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.

2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

Top Gear's latest trailer shows off a golden Bugatti Chiron

Top Gear is returning on March 5, and after a lackluster first series with the new hosts, the new group seems determined not to hit a sophomore slump. Chris Evans is gone, and the latest teaser trailer shows the new trio of Matt LeBlanc, Chris Harris, and Rory Reid strapped into some pretty fantastic cars, including the Bugatti Chiron and the Ford GT. All of the typical Top Gear segments appear to be present, though the quick cuts don't give us many details. The trailer shows a copious amount of powerslides from an assortment of cars, and even Chris Harris racing around Daytona. Aside from the Bugatti and Ford, cars from Porsche, Lamborghini, Ferrari, BMW, Aston Martin, and Alfa Romeo are all present. Co-hosts Eddie Jordan and Sabine Schmitz don't appear at all, so it seems their roles may be downplayed to focus on three guys, as was the case pre-reboot. We have some hope for this re-relaunched show and will be keeping an eye out for more details in the lead-up to the series premiere.
