US i3 Deliveries Begin!

i3's sitting at a port in the US awaiting vehicle carriers to take them to dealerships
BMW of North America issued a press release today confirming that US i3 deliveries have begun. Not such a surprise since as of yesterday dealers across the country began taking in i3's.

BMW of North America's CEO Ludwig Willisch said of the i3 launch: Today marks a big day at BMW of North America – What started out as a dream for an innovative sustainable vehicle under the BMW i brand can now be found on streets across the U.S.”

There are currently hundreds of i3's in the US, either at the port, dealerships or en-route to the dealership. However only the BEV i3 is being released at the moment. The range extended version (REx) is still being held up at the port for what is assumed finalization of the EPA certifications. That is expected to be finished very soon and the REx vehicles can then begin shipping to dealers also. 
And so it begins...

Breaking: BEV i3's Arrive At Dealers Monroney Label Revealed

As expected, the i3 is officially the Most Efficient Car in America. The 81 miles per charge range is a bit disappointing though.


BMW has just now released the BEV i3's from the ports and they are en-route to dealers. The i3's with range extenders have not been released and will remain at the ports a little longer. The common belief it that the EPA range certification for the REx hasn't been finalized yet so the REx cars need to wait a little longer at the port.

The BEV i3 is rated at 81 miles per charge, which is somewhat of a disappointment, but the efficiency figures are off-the-charts good. 138 MPGe City, 111 MPGe Highway and 124 MPGe Combined. That makes the BEV i3 the most efficient automobile on the road in America, and by a good margin. More on this later, I just wanted to get this up as it was breaking.

How Much Does it Cost to Charge an Electric Car?




There are many reasons for considering making an electric car the next car you buy or lease. Besides the many environmental benefits, the promise of energy security, the silky-smooth driving experience with instant torque available without delay and low maintenance, one of the best characteristics of electric vehicles is how little they cost to operate. I've covered this topic here before, but this is something that really needs to be driven home. While Electric cars are currently more expensive than their conventionally-powered counterparts, the total cost of ownership over time can certainly be less, and in some cases much less.

Just as with gasoline cars some EV's are more efficient than others, but the average EV needs about 30 kWh’s of electricity to power the vehicle for 100 miles. For example, the EPA rating for the Nissan LEAF is exactly 30 kWh’s per 100 miles. A Tesla Model S 60 is rated at a combined 35 kWh’s per 100 miles and uses a little more energy since it’s heavier and more powerful than a LEAF, while the Chevy Spark EV has a combined consumption rating of 28 kWh’s per 100 miles. The BMW i3’s EPA consumption ratings haven’t been announced yet, but since the i3 is likely to be wear the “most efficient EV” crown, I expect it to be rated somewhere around 26kWh’s per 100 miles. The consumption for all electric vehicles can be viewed at the US Department of Energy’s website: www.fueleconomy.gov

According to Researchers at the University of Michigan Transportation Research Institute, the sales-weighted average fuel economy of all new vehicles sold in the United States in 2013 was 24.8 mpg. The average cost for a gallon of regular gasoline in the US over the past three years was $3.53/gallon. By using 15,000 miles as the average amount of miles a person will drive in a year, the annual cost of gasoline for the average car will be $2,135 per year, using the average cost of gasoline from 2011 through 2013.

Electricity rates vary much more than gasoline across the country, but the cost is much more stable. Unlike with gasoline, there aren’t huge spikes in electricity rates if a refinery has a problem, and neither does the price skyrocket when there is political instability in one of the large oil producing countries as we have seen lately, since all of the electricity we use in America is domestically produced. The average cost of electricity in the US is 12 cents per kWh. Therefore the average person driving an average EV 15,000 miles per year pay about $540.00 per year to charge it. As mentioned, the cost of electricity can vary greatly depending on where you live, but in order to equal the price of the average gasoline car’s fuel costs, the price of electricity would have to be four times the national average, and cost 48 cents per kWh. Nowhere in the US does electricity cost even close to that much. So the average American would save roughly $1,600 per year in fuel alone, and that's if gasoline prices remain around $3.53 per gallon. Gasoline prices do frequently spike up and down, but in the long run they always goes up. Electricity costs do eventually increase also, but not nearly at the pace of gasoline. Plus with fewer moving parts, EV's cost much less to maintain. If you combine the fuel savings with the reduced maintenance costs, it's clear to see an EV will cost you much less in the long run, even if the vehicle costs a little more up front.

Another great thing about electric cars is that you can easily reduce your electric bill by $40 to $50 per month just by being more efficient, and therefore completely eliminate your transportation fuel cost! You really can't use less gasoline unless you drive less or buy a more efficient car, but you can reduce your electricity usage at home and still drive as much as you always have. Simple measures like a programmable thermostat and the use of compact florescent or LED light bulbs can make a big difference. In fact, five 100 watt light bulbs left on continuously for a year use nearly the same amount of energy as it takes to power an electric car 15,000 miles! Here's how: five 100 watt light bulbs use 500 watts per hour. In 24 hours they use 12,000 watts or 12kWh. In 365 days they use 4,380kWh’s. A typical EV that uses 30 kWh’s for every 100 miles will use 4,500 kWh’s to drive 15,000 miles. Simply by turning unnecessary lighting off at your home, you can drastically reduce or completely eliminate your annual transportation fuel cost. Try doing that with a gasser!

Is The BMW i3 "Too European" For the US Market?



It's been called edgy, futuristic, polarizing, ground breaking and even flat out hideous. It has funky lines, rear coach (suicide) doors that can't be opened unless the front doors are and rear windows that are permanently closed. The nose has a pronounced "underbite" that any respectful orthodontist would love to correct and the tires are so skinny they look like they should be on something coming out of BMW Motorrad, and certainly not on a proper BMW automobile.

The internet is full of extremely harsh criticism of the i3's exterior styling. However most seem to praise the interior for it's modern, stylish and open feel, especially for such a small car. I don't think I've read a single article where the author didn't at least approve of the interior design, while most gave it very high marks. The term "Scandinavian loft" has been used frequently to describe the modern, open feeling the i3's interior offers.

But then there's the unconventional exterior styling that many people just can't get past. I have to admit, I didn't love it when I first saw it, but I never actually hated it. Then I felt a lot better once I saw it in person and got to drive it. The styling has definitely grown on me and I genuinely like how it looks now.  Others don't fell the same way. In fact, the i3's unique appearance has been discussed ad nauseum since its introduction. Here are a few examples:


On this message board, one person asked the question: Did they try to make it ugly?

Brad Berman of plugincars.com: Did BMW screw up the visual design of i3 electric car?

Perhaps one of the most offensive stories was from The Slate when they wrote: BMW i3 review: Electric car is a cheap, ugly Tesla Model S with an SUV on the side

Would this Citroen be popular in the US?
Then I started thinking about all the criticism and began to wonder if it is mostly driven by American opinions. BMW has consistently maintained the i3 is a "city car". Unlike Europe, city cars just haven't been accepted here yet. The European roads are full of small cars that would certainly appear "unconventional" to American motorists. Take smart for instance. There are smart cars everywhere you look in Europe, yet smart can barely sell a few hundred cars a month in the entire US. Also, many of the cars there look a bit more modern than what you typically find on American roads. Are Europeans just more accepting of new ideas and styling that pushes the limits of acceptability? Is form following function an easier sell to the European car buyer than it is to their American counterpart?

John Voelcker, editor of Green Car Reports and one of the industries most respected journalists covering the green car and alternative powertrain scene recently wrote this: 

"I'd agree that the BMW i3 is the best city car yet developed. Which is fine for Europe. The problem is that in North America, virtually no one has ever said, "Honey, we need to go buy a city car!"


Will America warm up to the unconventional BMW i3?
This does make sense but I'd argue that while it is a "city car", it is just as well served for the outlying suburbs of the big cities, making it a great commuter car for the daily grind, while still offering the spirited driving experience many want for the weekend joy ride. Which leads to the next questionable decision BMW made which is likely part of the reason so many people have been critical and that's the range. You can't go too far on that weekend cruise unless you paid the additional $3,850 and got the range extender. The EPA range rating hasn't been announced yet but it's widely expected that the i3's electric range will be officially pegged at about 80 to 85 miles per charge. America's a big country and with gasoline relatively cheap compared to the average price in Europe it's common to drive hundreds of miles at a clip here. I believe if BMW would have increased the i3's range a bit, so the EPA range rating was 100 or more miles, they would have eliminated a lot of the negativity surrounding the car so far. Of course the Europeans would like more range also (who doesn't?). It just seems less important there since they are likely to drive less than we do in the US and some would argue that European customers look at a car purchase more pragmatically in many cases.

BMW CEO Reithofer introduces the i3
Will the "unique" styling and short range conspire to limit the i3's success in the US market? Only time will tell. There will certainly be an initial surge of orders but once they are filled will the i3 continue to attract eco-conscious buyers to the brand. According to BMW, i3 ordering has been robust and they have over 11,000 orders in the bank worldwide. US ordering has just recently begun and the first deliveries are due here in only a few weeks but BMW hasn't said how many of the 11,000 orders have come from American customers.  BMW must be happy with i3 sales so far though because they recently ordered two more Engle molding machines that make i3 body shell components. They are only about six months into production so if they need to buy more production machinery already, that is likely a good sign.

Ready or not America, here i come!
What do you think? Do you like the i3's appearance? Do you hate it or are you in the middle? Will it be more accepted by European customers or will it have universal appeal? Let me know in the comments below.

To REx or Not To REx, That is The Question: Part 2

To REx or Not to REx, that is the question many potential i3 buyers are struggling with now
Back in September of 2011, only 6 months after I started this blog, I wrote a post titled "To REx or Not To REx, That is The Question". At the time, very little was known about the i3, and even less was known about the range extender; other than it would be available as an option and would appear sometime after the initial i3 launch.

The sign at the New York BMW i Born Electric Tour claimed a 100 mile range for the i3. It's looking like the EPA range rating will fall short of that.
My conclusion back then was if the BEV i3 had a real 100 mile range I would probably pass on the REx, but if the range was closer to 80 miles and the REx was only about $3,000, then I would probably go for it, providing I didn't have to wait too long after launch for the REx to be available. As it turned out, my fears about the range were justified. Even though I don't have proof of the EPA range rating yet, I feel confident by now that the range will be less than I had hoped, and that the i3 will have an EPA range rating that is somewhere in the 80s. I drive a lot and that's just cutting it too close for me. At 90-95 miles per charge I could probably do it, realizing that after 2 or 3 years the range will likely be in the high 80s anyway. A 100 mile EPA rating would have absolutely eliminated the need for the REx, but no company outside of Tesla is offering that on a real EV (one that is available across the Country). So at $3,850 the REx is a little higher than I would have liked it to be, but it's not astronomically overpriced, considering the utility value of having it on board and ready when you need it. 

So after bouncing back and forth a few times, I've decided I'll be getting my i3 with the range extender. After about five years of driving pure electric, I'll be back to hauling around an ICE. I don't love the idea, but I'm not hung up on "pure EV" dogma either. The goal is to use less gas and if the range extender allows me to drive on electric the vast majority of the time, yet still have the utility I need on the days I need to drive farther, than the goal is accomplished. The i3 simply won't have the necessary all electric range that's necessary for me personally but that doesn't mean it's not enough for many others. As you can imagine I'm not alone with the struggle to decide which version of the i3 to get. Now that the i3 is available to order in Europe, and only weeks away from being available in the US, I'm reading posts in the i3 forum and in our i3 Facebook group where others are grappling with the decision of if they should go BEV or REx.

I'll try to outline the pros and cons here. If you think I miss something please feel free to add your reasoning in the comments section. Here are my top six reasons for and six reasons against the range extender:

Why go for the range extender:


The added utility. Not having to plan out your mileage or look for public chargepoints if you know you'll be pushing the range on a particular day will be a welcome feature to many people. You won't have to think twice if your plans change and you need to drive more miles than you planned that day, and on days you know you'll be driving far you won't have to use the other family car, borrow a gas car or use a car sharing or rental service. With the exception of extremely long drives (hundreds of miles) that will take you up extended long mountainous routes the i3 with the REx can take you wherever you need to go without worry. Also as the car ages, the battery will lose capacity and your range will shrink. A new i3 with an 85 mile range may only be able to comfortably deliver 75 miles after 3 or 4 years. The REx means the car will always deliver the same utility regardless of how old it is and what shape your battery is in.

No range anxiety. There is some over lap with the first reason, but this really is another issue in itself. There is a difference in not using the car one day because you know the range wouldn't be enough, and miscalculating your total miles because your route had a detour, or your life had a detour that day. It happens. You  can plan your day all you want but things come up and you often need to drive farther than you thought you would have to. Usually the extra range you have is enough to get you home, but there are those days where you just come up short and can't make it. The last few miles you are gripping the steering wheel a little tighter and looking down at your range gauge every minute or so. I've been driving electric for nearly 5 years now and I can honestly say these kinds of issues don't happen often, in fact they are very rare. However when they do happen, it isn't fun. I can remember walking home at 2am last summer and thinking about how great it would have been to have that little REx motorcycle engine on my ActiveE. On that night, I ran out of charge about a quarter mile from my house. What made it really interesting is I live in a very rural area of New Jersey. There are no streetlights on my street and it's really pitch dark at 2am. Add to that I saw a bear walking on my lawn a few weeks earlier so as I was walking home I couldn't help but think of the headline, "EV advocate gets mauled by bear walking home because his electric car ran out of charge." I don't know if that is range anxiety or bear anxiety, but I could have really used the REx that night. I know some would say just get an EV with a bigger battery. No matter how big the battery is there could always be occasions when you miscalculate your range or drive farther than you planned and come up short. The range extender virtually eliminates any range anxiety unless you live in an extremely remote area where there aren't charge points or many gas stations where you drive. If that's the case, perhaps an EV isn't the best choice for you right now anyway.

Resale value. There isn't a lot of empirical data since modern EVs haven't been available long enough to really establish how much a pure EV will depreciate as compared to an EV with a range extender. Now that the earliest LEAF and Volt lessees are beginning to return their cars that were on three year leases, I believe in a year or so we can properly gauge if there is much of a difference. I suspect that electric cars with range extenders will fare much better in the second hand market. I know if I were looking to buy a three year old i3 I'd be much more concerned about the condition of the battery if it didn't have the REx. After three years there will be range degradation, there is no way around it as the battery ages. Will a three year old BEV i3 still have 90% of its original range? How about 85%? We simply don't have the answer yet. That uncertainty really hurts the value of the car. The potential new owner won't really know how far it can go until they buy the car and live with it for a while. However if the used i3 has the REx, then the all electric range isn't nearly as important. The buyer can still do anything they want with the car. They can drive it as far as they want to and the only negative they have is they may use a little more gas than when it was new because of the lower electric range. If it's a pure BEV they also have to worry about how many more years they have with the car until the range really impacts the cars utility - the REx removes that concern. Of course if you lease the car this isn't your problem and one of the reasons I recommend leasing if you are in the market for an EV today.

When will this be commonplace?
Lack of infrastructure. If there were level 2 charging stations in every parking lot, and finding a place to plug in while you work, dine and shop was without hassle, then daily life with a ~80 mile BEV would be simple. If we also had a robust DC quick charge infrastructure then long distance travel would be easy, even if it meant stopping more frequently then you would have to for a gasoline car. However we just aren't there yet. Outside of certain areas of California and a couple other progressive areas, charging infrastructure is still in its infancy. It's going to take a while for EV charging to be ubiquitous. I do believe we'll get there, but not for a while. There will be a lot of growing pains and I believe the number of EV's sold will greatly outpace the number of public charge points installed. For most people outside of a few select areas, I fear finding available EVSE's will be very difficult for the foreseeable future.


My ActiveE battery was frequently drained
Damage from frequent deep discharges. This may be a minor concern, but since the REx will turn on at about 6% state of charge, the battery won't be run down to very deep discharges. There is about 10% buffer when you drain the i3's battery completely so when the REx turns on the real state of charge is actually about 15%. The buffer is there so you don't do really deep discharges which would damage the battery. However I can't help but think if you are a high mileage driver like I am with a BEV i3 and frequently roll into your garage with the state of charge below 5% of the available capacity, the cumulative effect of doing this frequently will have negative effects on the battery. With my MINI-E and ActiveE, there were many times I drained the battery well under 5% and even drove them until they just stopped and wouldn't go any farther a few times. This isn't good for the battery, but since these were test cars that would be taken out of service after two or three years there was really no reason to pamper the battery. However if you shell out $45,000 for a new i3, you will want to take good care of your battery, as it's the most expensive component of the vehicle to replace. Frequent deep discharges can bring on early degradation which will mean less range and perhaps even cause more deep discharges and accelerate the early capacity loss of your pack.  

My ActiveE preconditioning in the snow
Cold weather range degradation. If you live in an area that gets cold during the year this is something you need to be very cognizant of. Even with a sophisticated thermal management system like the i3 has and the ability to precondition the battery and passenger cabin, the range of an electric vehicle is less when it's cold outside. The combination of the need to use energy to power the cabin heater, the seat heaters, the defroster, etc, plus the fact that the batteries simply cannot store and use the same amount of energy as efficiently as they do when it's warm conspire to cut into the range. Without having thoroughly tested the i3 in cold conditions, I still feel confident saying you can expect at least a 20% range reduction in temperatures below freezing, and that number could quite possible as much high as 30%. So lets say the i3 gets an EPA range rating of 85 miles per charge. I wouldn't expect the average driver will get more than 60 - 70 miles per charge when they are driving at or below freezing, and even less as the temperature drops much lower than that. It should be noted that this isn't permanent range degradation, like I was referring to above.  As soon as the temperature rises back up again, so will your range, but that could mean for 3-4 months a year you have to live with an EV will less than 70 miles per charge. With the REx all this means is you may use a little gas, but you won't have to change your driving style, find secondary roads to your destination so you can drive slower or wear a hat and gloves so you don't need to use the cabin heater.

Reasons against getting the REx:


Do you mind if I smoke?
It's an electric car! - You don't want really want to put gas in it do you? The whole reason for going electric is to get away from gas, right? Well there are lots of reasons for going electric while not needing to buy gas anymore is definitely one of the top ones. The way I see it, my goal is to use as little gas as possible. My EVs are mostly powered with electricity generated from my solar array which really makes them as close to true zero emission vehicles as possible. I don't feel bad if I end up burning 10 or 20 gallons of gas in a year with my REx i3, after all I used to use that much gas every four days when I commuted in my SUV. Still an electric car that burns gas can leave a foul taste in your mouth as the exhaust pipe does when the REx is running

This stuff shouldn't pour out of an EV!
ICE complexity means added maintenance. One of the great aspect of electric cars is their simplicity and
extremely low maintenance. Slap an internal combustion engine as a range extender in there and you just complicate things. Now oil changes, tune-ups, filters, mufflers, etc are all part of ongoing maintenance again, just when the electric car promised to put all that in your past. The only redeeming aspect is since you'll likely only use the REx occasionally, the maintenance schedule will not be nearly as intensive as it is on a normal ICE car. Still - this is a major drawback in my opinion.

The added weight of the REx reduces the cars efficiency and performance. The i3 is the most efficient electric vehicle on the road. Everything BMW did while designing it was centered around lower weight and increasing efficiency. The REx adds 265lbs of dead weight to the car, which has to be lugged around everywhere you go. Even if you don't use the REx for a month at a time, every mile you drive you'll be carrying it with you. The efficiency will take a hit and you'll be using slightly more electricity to power the car whenever you drive it. It's kinda like going hiking and carrying 30 water bottles in your back pack every time you hike, even though you usually only need 1 or 2 of them for 95% of your hikes. Plus, the added weight robs some of the performance. The all electric i3 will go 0-60 in about 7.0 seconds, while the REx i3 will need about 7.7 seconds. Still pretty quick, but if you're driving a REx i3 and a BEV i3 pulls next to you at a streetlight, kindly decline the invitation for a race.

It takes a little away from the cool futuristic feel of the car. Driving electric is a blast. It's a different driving experience that most will tell you is actually better than driving ICE. There is also a really cool feeling that you are really driving the future. The ultra silent vibration-less cabin, the instant torque and feeling that you are almost being pulled along by a string instead of the car providing the propulsion really lets you know you are definitely not driving something from a past generation. Add to that the i3's futuristic architecture, advanced electronic features, extensive use of carbon fiber for the passenger cell, aluminum for the frame and thermoplastic for the outer skin and this is indeed a car of the future that you can drive today. Do you really think an internal combustion engine that's vibrating and belching pollutants into the air as you drive along really belongs there? Of course it doesn't.

It will complicate your conversations: I've been driving electric for nearly five years now and I still get people asking me about my cars all the time. I can't go to a car wash without someone asking me about it and often when I return to my car parked in a lot at a shopping center there is someone there looking at it and wanting to ask me about it. With a REx i3 I can no longer say, "Yeah, it's all electric and I love never buying gas!" like I do now. I see the conversation going something like this:

Them: That's an interesting car is it electric?
Me: Thanks, yes it is.
Them: Wow! Cool  - so it's all electric?
Me: Well it's not all electric, but 99% of the time I drive it is all electric. It has a small gas engine that is used to recharge the batteries if I need to drive farther than the electric range will allow.
Them: Oh, so it's a hybrid. My neighbor has a Prius and loves it.
Me: (Groaning under my breath) No, it's an electric car with a range extender.
Them: So it's not like Prius then?
Me: Well it's not like the old Prius, but there is a new Prius now that is a plug in Hybrid and it's kinda like that but has a much greater electric range.
Them: So it's kinda like the plug in Hybrid Prius, but it's not a hybrid you say?
Me: Have a nice day. (Drives off mumbling)

I've driven the i3 a few times now, and the distinctive styling attracts a lot of attention. If you buy an i3 expect a lot of curious people asking you questions about it and the range extender definitely makes explaining the car more difficult.

Cost: The range extender option costs $3,850.00 in the US and that's a lot of coin. There is also the concern that in some states getting the REx option will then disqualify the car for the zero emission tax exemption. If that is the case, the range extender will end up costing them closer to $7,000 because the sales tax will add another $3,500 or so to the price. However I don't think this will be the case because I know BMW has been working very hard behind the scenes to get the i3 REx classified as a zero emission vehicle under the CARB BEVx rule. Hopefully we will get clarity on this soon because I know states like NJ, Washington and Georgia (possibly others also) all have tax exemptions and/or other state incentives for zero emission vehicles, but not plug in hybrids. Still, even if it only costs the $3,850, that is a significant additional cost.

Ultimately you have to decide what best suits your needs. I would hate to have someone buy a BEV i3 and then realize they can't live with the limited range and struggle with worrying about running out of charge. However I also don't want to give the impression that the BEV i3 wouldn't work for a lot of people. I happen to drive much more than the average person. I drive between 33,000 and 35,000 miles per year and average around 85 miles per day so for me the REx i3 makes more sense. However as I've said, I have lived the past 5 years with pure EVs and really didn't have too many instances when I wished I had a range extender. Only you know what's best for you. That reminds me of one of my favorite Dr Seuss quotes: 

“You have brains in your head. You have feet in your shoes. You can steer yourself any direction you choose. You're on your own. And you know what you know. And YOU are the one who'll decide where to go...” 
This one has the REx
You have brains in your head. You have feet in your shoes. You can steer yourself in any direction you choose. You're on your own, and you know what you know. And you are the guy who'll decide where to go.

BMW i3 Range Extender: How Robust Will It Be?



There are still many unanswered questions about the i3. What will the EPA range rating be? How will is fare in NHTSA and IICA crash tests, will it cost more to repair, and so on. However there is one particular feature of the i3 that continues to dominate the discussion boards and forums: What can and can't you do with the REx?

Back in June before the i3 was officially introduced, I did a blog post on this very topic which turned out to be very popular. In fact, it's one of my top viewed posts and has been viewed over 5,000 times so  far. We now know a few more details since then so I thought it was a good time to give an update here. While I have driven in REx i3's, unfortunately I haven't had the chance to thoroughly test on while it was in range extender mode. That wasn't a coincidence. BMW has still be fine tuning the software for the REx and hasn't allowed the press access to them for complete testing. However, somehow over in the UK The Telegraph got hold of one and was able to take to for a long drive and use the range extender. Overall the review was pretty favorable and the author gave the i3 four out of five stars. However that's not the whole story. The real "story" within this story is that the author reported this about the range extender and it's caused a but of a stir:

"I thrummed along at 70mph, but it soon became clear that at this kind of speed our comfortable range between fill-ups was more like 40-50 miles. Still, it was impressive how, even when it says it’s flat, the car maintains enough battery power to give an instant shove of torque. Only if you really run it down, which you’ll have to try pretty hard to do (or so I’d been told), would you compromise the performance. Which is what happened next. 


I’d just come through a heavy but localised rain storm on the M20 when the i3 started to slow. It was a gradual process, from motorway cruising speed all the way down to 44mph. By this time I was travelling up a slight incline and had effectively become a slow-moving obstacle. Lorries were catching me with quite frankly terrifying closing speeds. It was three or four minutes - which was long enough to make me consider pulling over - before the i3 recovered; just as slowly as it had lost speed, so it crept up. “It’s not a limp-home mode as such,” a BMW spokesman later told me, “but once the charge runs down to five or six per cent and the range extender cuts in, if you keep driving at 75-80mph it can’t maintain the charge.” Rather than damage the battery by running it completely flat, the i3 had restricted our performance."


This Telegraph video above doesn't mention the difficulty they experienced with the car slowing down at all even though they show it driving along on the M20 while it was raining like they printed version said. That's strange to me since the article seemed to make a big deal out of it. I would have like to have seen video of the car during the explained "slow down" event.

The i3 REx Engine
I've had quite a few conversations with the engineers and product managers at BMW about the range extender and while they are cautious no to over sell it's capabilities, everyone I have talked to promises it's not anything like a "limp mode", and in fact you can do just about anything with it as long as you understand how it works and drive accordingly - I take that as monitoring your speed and if you know you'll be driving up a long steep incline and take it easy for a few minutes before you begin your ascent so the REx can build up a little extra reserve power for the climb. There has been a lot of talk around the fact that in the US, you can't manually engage the range extender once the state of charge is below 75% as you can in Europe. The concern is with the range extender coming on at such a low state of charge (at ~5% SOC) that there may not be a large enough buffer for those instances when the car needs continuous supply of a lot of energy for high speed driving or to climb long, uphill grades at highway speeds.

I don't have the exact answers as to what exactly is possible and what isn't. In fact, I'm not even sure it's possible to offer such a definitive explanation. Sure, the engineers can offer a formula based on total passenger and cargo weight, vehicle speed, head or tail winds, percent of grade you are climbing, etc but who will even understand that let alone be able to transfer that to an actual real world driving situation? There are so many different situations and roads it's just not possible to give a clear black and white definition of what it can and what it can't do and I believe BMW will likely struggle with how to explain this to their customers - maybe that's why they haven't even tried to explain it yet! I have made a request to the program managers to let me drive an i3 REx for a day once one is available. I'll test it in every possible situation I can come up with in the time frame I have including a 220 mile trip to Vermont. Hopefully my request will be accommodated because I believe I can clear the air on this as much as possible, however as I mentioned above there are endless specific driving circumstances so no test will completely satisfy everyone. My advice: Drive one in REx mode to satisfy your concerns before you plunk down your money. I'm sure you can leave a deposit on one and have it refunded if you are not satisfied with the performance once you get the test drive opportunity.

i3 Product manager Oliver Walter
I can say I have spoken with program managers that have driven the i3 REx extensively, and they have assured me that on flat ground, you really have to purposely try to defeat it in order to use more energy than it produces and that it can easily drive along at 70 mph for as long as you need to and still have enough energy for short bursts of power to climb hills along the way. BMW i3 product manager Oliver Walter in particular has assured me the range extender is robust and will be able to power the car in just about any circumstance without the driver even noticing any difference than when it's in pure EV mode. The question becomes how fast can you drive and for how long, up how steep a grade, and right now, we just don't have definitive answers.

So why can't the i3's in the US have the same ability the European i3's have to manually turn on the REx ahead of time, when you know you'll need a lot of energy for demanding driving conditions like climbing a mountain later in your trip? The answer is in the CARB certification of the i3. BMW needs the i3 to be certified as a zero emission vehicle in order to claim the most ZEV credits they can for each i3 sold. However the benefits aren't only for BMW. BMW has been working behind the scenes to make sure that i3 buyers get the same tax credits, tax exemptions and benefits like HOV access that zero emission vehicles get, which in many cases is better than what is offered to PHEV buyers. For example here in NJ, if I buy a zero emission car like a Tesla Model S, I am not required to pay sales tax, but if I buy a Chevy Volt which has a range extender, it's classified as a PHEV and I have to pay sales tax. So if BMW by getting the i3 REx certification approved, manages to get New Jersey to classify the i3 REx as a zero emission vehicle, then I will save about $3,500 in sales tax. To me, that's worth losing the ability to manually turn on the REx early because there will be so few instances that I would ever need to; it's just simply not worth it. This isn't just for NJ though, there are quite a few other States that offer different incentives for ZEV's as compared to PHEV's. However as far as I know, BMW is still working out these details State by State and they haven't announced exactly what the certification will mean in each particular State just yet. As soon as there is more to report on the certification and State benefits I'll have it up here, and hopefully I'll get to report first hand on how the REx performs sometime soon. Happy Holidays everyone!


Of course a robust network of DC quick chargers like the one pictured here would render the range extender irrelevant. But are they coming?

US i3 Orders To Begin in November

InsideEvs.com recently reported that Jacob Harb, BMW's North American Manager for Electric Vehicles, told them that i3 orders for US customers will begin in November. That means we'll soon get information like pricing for options, warranty details and hopefully what leasing deals will be offered.

BMW has reported strong demand for the i3 in Europe with over 8,000 pre-orders already and the car won't even be available for another month there. Here in the States we'll have to wait a little longer. All BMW has officially said is that the i3 will launch here in the second quarter of 2014, and recent rumors have been pegging the launch for April or May which would mean early to mid Q2.

California dealers have also been telling their customers that they will be getting i3'\s for display and even test drives, and that there will be as many as 50 i3s at the LA Auto Show in late November for driving events. That would make a lot of sense since the LA Auto Show is one of the big auto shows in the US and California is the number one market for plug in vehicles. 

One factor that can influence the i3's popularity in the US is its EPA range rating which hasn't yet been announced. I have maintained for a long time now that I would be very disappointed if that number comes in lower than 90 miles per charge. Unfortunately judging from the early test drive reports from some reporters like John Voelcker of High Gear Media, it may in fact be lower than 90, and may even be substantially lower than 90 miles per charge. I'm not going to go into this too much just yet because it would just be conjecture. Once the EPA rating is announced I will have a detailed post up within a day, I promise because it is a very important topic to discuss.
