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.

Jaguar Land Rover to drop supercharged V8 for turbocharged BMW power

There are few things that sound as good as Jaguar's 5.0 liter supercharged V8. As great as it is when the supercharger whines or the exhaust cracks and pops on throttle lift-off as the air pressure equalizes, the basic design dates back to the '90s. Plainly, the engine isn't as efficient as it needs to be, but designing a new V8 from the ground up is an expensive proposition. Instead, Automobile reports that Jaguar Land Rover is set to use a twin-turbocharged V8s supplied by BMW. Scalable architecture is all the rage as automakers streamline designs in order to save costs. For example, Jaguar's current supercharged V6 is quite literally a V8 with two holes missing. They didn't even change the length of the block. It seems both of those designs are on their way out, with the V6 being replaced by a inline-six closely related to the company's inline four. It seems that rather than designing an new and expensive V8 for their top of the line models JLR, is sourcing from BMW. From 1994 to 2000, BMW owned Land Rover. A few models, including the Land Rover Range Rover, used BMW engines then and in the initial years of Ford's JLR stewardship. It seems things have now come full circle. BMW currently makes a twin-turbo 4.4 liter V8 that produces anywhere from 440 to 600 horsepower, depending on the application. Automobile says that a new 4.0 liter V8 is in the works and that it will most likely be the engine that JLR uses. Expect it to be more powerful, more fuel efficient, and lighter than what both BMW and JLR currently offer. This seems like a win for both companies. BMW gets to offset the cost of a new motor while JLR, a smaller company, doesn't have to invest in a whole new architecture. As automakers search for ways to cut costs, expect collaborations like this to continue. Infiniti and Mercedes-Benz both share a four-cylinder engine. Ford and GM have worked together to design a shared 10-speed automatic. While we may lament the loss of that wonderful Jaguar Land Rover engine, we can still be happy that they haven't abandoned the V8.

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
