Might these new 94 Ah cells from Samsung SDI make their way into the 2017 BMW i3? About a month ago BMW CEO Harold Krueger surprised the EV world by casually mentioning in an interview with Die Zeit that in 2016 the i3 would have increased range. That of course sparked a lot of online speculation as to how would BMW accomplish this. Did they figure out a way to squeeze in more of the same 60 Ah Samsung battery cells that the i3 currently uses? Might they have sourced higher energy density battery cells from another supplier? Could Samsung have made the new 94 Ah cells available to BMW now? According to Samsung's Battery Technology Roadmap it didn't look like they would have those cells available for at least another year. From the Samsung SDI website. The 94 Ah cells aren't even listed as available (click to enlarge) According to some well connected insiders, it is beginning to look like BMW will indeed use Samsung's now 94 Ah battery cells in the 2017 i3 which will b...

Fill 'Er up! I know many readers here have spent countless sleepless nights pondering the the age-old question: How long does it take to refuel a BMW i3's tiny gas tank? Well maybe not, but I have had people argue that driving the i3 REx on an extended trip would be very inconvenient because they would have to stop to fill up the gas tank every 50-60 miles. I've done quite a few road trips with my i3 REx, and stopping once an hour for a couple of minutes to refill the tank never really bothered me much. I wrote a post last year which detailed a 462 mile round trip I made to Vermont from my home in New Jersey and refueling was one of the topics that many people commented on. On that trip, I had to stop for gas a total of seven times, as I only recharged the car once, which was at my destination. I drove 111 miles on battery, 351 miles on the range extender and used a total of 9.87 gallons of gas, averaging 35.5 mpg. It was snowing in Vermont when we arrived In that post, I w...

BMW CEO Krueger revealed plans to increase the i3's range in 2016 It's no secret that if BMW wants the i3 to continue to remain relevant they will eventually have to increase its all electric range. In fact, in about a year there will be no less than two electric vehicles available in North America that have double the i3's all electric range and also cost less. Nissan will be launching the second generation LEAF, and Chevrolet will bring the Bolt EV to market by the end of 2016 and they are both rumored to have approximately 200 miles of electric range. I think it's fair to say most people expected BMW to up the i3's range to stay competitive, but when they would do so was not known. Until now. BMW CEO Harold Krueger in an interview with Die Zeit recently said this about the topic: “Battery cell technology continues to evolve. The range of the i3 will be increased in 2016. A further technological improvement is to be expected in three or four years: Then you’ll be ...

We stopped at the Big Moose Deli in New York for some coffee. It's about ten miles from the Vermont border.  Perhaps the most discussed topic of the BMW i3 is the implementation of the range extender for the North American market. In an effort to have the vehicle qualify for the California Air Resource Board BMW set restrictions on how and when the range extender can turn on, effectively reducing the utility of the REx. These restrictions are most apparent when attempting to use the car for long journeys which include drastic increases in elevation. This topic has been covered here and on every other EV site extensively, and recently it was announced that BMW is working on a software update that will allow, under certain conditions,  the range extender to come on much earlier than the 6.5% threshold it currently uses. I am actually beta testing that software for BMW now, having had it installed on my i3 just last week. The new software also includes some other updates that wil...

The infamous Check Engine light of the BMW i3 REx Many people that order the range extender option on the i3 do so because they just aren't comfortable with the BEV i3's 81 mile EPA range rating. Personally I really didn't want it but my driving demands dictated that I really needed it. If the i3 had 15% to 20% more range I would not have ordered the REx and I suspect there are a lot of others that would fall into the same category as me on this. We know it's there and we aren't particularly proud of hauling around the oil, gasoline and the rest of the muck that goes with it. So the last thing we really want is to be constantly reminded that we have a gasoline engine in our shiny, new electric cars. Unfortunately that is exactly what is happening. The day after a picked up my car the check engine light (CEL) illuminated for a few hours and then shut off. I called my dealer as soon as it went off and was told to bring it in so they could check it out. Then when it tu...

I was recently interviewed by Brad Berman of Plugincars.com about my initial thoughts on my i3. The interview just went live on the site so I've bought it over here for my followers to read. Please leave your thoughts on my answers in the comments section. ____________________________________________________________________________ Tom Moloughney, long-time EV driver and first owner of a BMW i3 with the range-extender option, answers fundamental questions about the car. 1) How is the BMW i3’s range-extending system different from the Chevrolet Volt and Toyota Prius Plug-in Hybrid? The range extender on the BMW i3 works differently than systems on plug-in hybrids (that to varying degrees sometimes power the wheels from the engine). The rear-wheel-drive i3 is the only pure series plug-in hybrid currently available. The i3’s two-cylinder range-extender engine never mechanically drives its wheels. The Fisker Karma worked this way, but that vehicle is no longer in production. 2) ...
