255 miles of combined range? This range estimator is probable a little more optimistic than real life, but I definitely believe 200 miles is possible with the new 2017 i3 REx.  What a difference three years makes.  I was able to secure one of the first 2017 BMW i3 REx cars that made its way into US dealer inventory, compliments of Chris Chang, Sales Manager at BMW of Bloomfield here in New Jersey. The vehicle is mostly the same as my 2014 i3 REx, the one big exception is it has the new 94 Ah battery cells, which increase the overall battery capacity from 21.6 kWh to 33 kWh without increasing its physical size. That was necessary, since this isn't a redesigned i3, so the battery modules had to fit in the existing battery tray. The 2017 i3 REx in Fluid Black next to my "Moloughney Red" wrapped 2014 i3 REx As much as I wanted to check out the moonroof option that this car had (finally the moonroof is available in the US!), there is no denying the single most important improv...

Over the course of 56,000 miles, I've driven on pure battery 96% of the time. My 2014 BMW i3 REx is now 27 months old, and the mileage on the odometer just recently surpassed 56,000 miles. I've needed a little over 15,000 kWh of electricity, and exactly 50 gallons of gas to power the vehicle thus far. That means I've driven on pure battery about 96% of the time, and managed an impressive overall gasoline consumption of 1,120 mpg. Normally I wouldn't highlight the gasoline use in my electric car; it's really not something most electric vehicle owners like to do. However, as many Chevrolet Volt owners can attest to, adding a range extender to a short range (under 100 mile AER) electric vehicle can expand its versatility immensely. While I haven't needed to use the REx often, there were plenty of times, especially in the winter, that I was very happy it was there. Back in early 2014, a few months before the North American i3 launch, I openly debated whether I'd...

Fluid Black as pictured and Protonic Blue Metallic will most likely be very popular colors in 2017 While many of the changes that the 2017 BMW i3 will be getting have already been announced; such as the availability of the anticipated 94 Ah battery cells, the new Protonic Blue color and a moonroof option, I've now learned there are also more subtle changes in the US for the new model year. First, and most interesting, is the revelation that BMW will indeed continue to offer the i3 with the current 60 Ah battery, offering a lower range and lower cost i3 alternative. This is something that I don't believe has been reported on any other EV news site to date. I speculated that BMW would do this back in March, when I wrote this post dedicated to the topic. BMW hasn't made any statements regarding offering two battery options, and made no mention of it in the the official press release   of the 2017 i3. Still, my sources tell me otherwise. The 60 Ah i3 will only be offered as a ...

The 2017 i3's 33.4 kWh battery pack is the same physical size as the current 21.6 kWh pack. BMW purposely designed the battery tray this way, so that future battery upgrades would be possible. Allowing the i3's battery to be upgraded was always BMW's plan. The concept of upgrading an electric vehicle's battery pack is certainly not a new one. In fact, it's something that many EV owners have been vocal about wanting to see offered. So the news that BMW will begin a battery upgrade program for their current i3 owners is good indeed, even if it may be something that isn't really necessary, or practical - yet. The big news in BMW i's May 2nd press release was, as expected, that BMW would be upgrading the i3's battery cells from 60 Ah to 94 Ah. This means the 2017 i3 will have an EPA range of 114 miles, up from the current 81 miles per charge. These new battery cells are physically the same size as the currently used cells, but can hold 50% more energy and ar...

The 2017 i3 comes with 40% more range than the current model. It's also available in a nice new color: Protonic Blue The worst kept secret of the BMW i3 is officially no longer a "secret". BMW has formally announced that the 2017 i3 will have a new, longer range battery pack. They are indeed using the new Samsung 94 Ah battery cells that I speculated they would five months ago . Just as I predicted the new battery pack is increasing from 21.6 kWh to 33.4 kWh, which in an increase in capacity of about 50%. However the range of the i3 BEV will only increase by 40% from 81 miles per charge to 114, which is less than i predicted. That's because BMW is now using a larger buffer (the difference between the total battery capacity and the usable capacity) and also because the car now weighs more (roughly 100 lbs more) because the new higher capacity cells weigh slightly more than the ones they replace.  The slight increase in weight will likely only have a very minor effect o...

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...
