BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

BMW i5, i7 rumors surface again

When we first wrote about a rumored BMW i5 in January 2014, after speaking to the Munich-based head of electric vehicle operations and strategy, BMW USA wrote to tell us that the "suggestion of a BMW i model larger than the i3 is hypothetical at this point." After that note came a year of speculation from places like Car and Driver, Automobile and Autocar zeroing in on what this "hypothetical" EV would look like. Car has this year's first scoop, laying out a few more of the ideas behind the expansion of the i line. Said to be aimed straight at the Tesla Model S, it is based on the long-wheelbase, Chinese-market 5 Series but will be badged as either an i5 or an i7. Expected to arrive in time for the 2018 model year to join the next-generation 5 Series, it will be priced to compete with the Model S, but loading up on options can push that beyond $125,000, according to Car. Outside will be a sedan body, possibly with cues from the 6 Series Gran Coupe and the next 7 Series. The internals will be a mix of components like steering, brakes, and suspension from the next ICE 5 Series, with a plug-in hybrid, battery-extending powertrain derived from the i8. Car's info suggests a four-cylinder motor with around 245 horsepower up front, with a 204-hp e-motor also up front and a 90-hp e-motor in the back, as opposed to the i8's single motor. That arrangement provides about 544 total horsepower and will allow the sedan to run in purely electric front- or rear-wheel drive, or as a petrol-electric all-wheel drive. Electric range should be around 80 miles, and the ICE will be limited to operation above 40 miles per hour. There's reason to start putting weight behind these specs because they repeat, almost exactly, those written in the Automobile piece from December. That story said BMW wants to build 30,000 of them per year, and a concept could come in 2017.

How to charge up your BMW i3 with a Honda

Behold a cheaper version of BMW's range extender for its i3 plug-in. And it's brought to you by ... Honda? Sort of, if you take the approach that Gadget Review took when it looked for an alternative to ponying up the $4,000 or so for the gas-powered i3 range extender that comes from the factory. What was procured was a Honda portable generator for Home Depot for the experiment, which involved gassing the generator up in a parking lot, plugging in the i3 and going out for a cup of coffee. The result was that, after about a half-hour of charging, the i3 picked up about four miles of driving range. Not exactly revolutionary but it least a bit instructive. And given that Honda generators start at about $800, the idea, while clunky, is potentially cash-saving. Gadget Review briefly took the experiment one-step further by trying to run the generator inside the back of the car and plugging in, complete with a rigged-up ventilation system, but the host thought better of it once he realized that there'd be suffocation involved. Why this was never tried on the Nissan Leaf, we'll never know. Check out Gadget Review's five-minute video below.
