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.

Automotive April Fools' joke roundup [w/videos]

Happy April, everyone. And we all know what this first day of the month means: April Fools' Day. Today is a national holiday for pranksters with the Internet acting as a serious enabler, and it's always fun to see what kind of vivid imaginations exist out there in the automotive world. The abundance of fake news gets a little old as the day rolls on, but we did manage to get in a few chuckles thanks to a handful of major automakers and automotive news outlets that got into the pranking spirit this year
Some of our favorites this year includes Subaru showing what happens when you combine a bunch of rumors, a Corvette some may have already thought was a joke or Honda providing some in-car innovation circa the late 1980s. Honestly, we're still waiting for official confirmation from Mitsubishi that the recently introduced 2014 Mirage is an elaborate April Fools' joke using a failed design intended for the 1995 Geo Metro. We dug up as much "official" OEM foolishness we could find, as well as some of our other favorites, and posted them all below.

BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.
