"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 buy the BEV or the i3 REx. I ultimately decided on getting the range extender, because the EPA range rating wasn’t as high as I had previously hoped. If the i3 BEV had an all electric range of 95 miles per charge or higher, I would have opted for the BEV. The EPA rating of 81 miles per charge just wouldn’t be enough for my high mileage driving needs, and even though I had lived the past five years with two pure BEVs — the MINI-E and ActiveE — I chose to go back to gas with the i3 REx."
