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.

This Or That: 1980 Oldsmobile 442 vs. 1989 BMW 635CSi [w/poll]

The last time I roped a coworker into an automotive debate, I lost. Resoundingly, I might add. Still, 2,385 voters chose to cast their lots for the Fiat 500 Abarth, as opposed to 5,273 choosing the Ford Fiesta ST, and so I can rest easy in the knowledge that at least 30 percent of you, dear readers, see things my way. I still like to think we have more fun, too.
My loss in the first round of our This or That series, in which two Autoblog editors pick sides on any given topic and then attempt to explain why the other is completely wrong, didn't stop me from picking another good-natured fight, this time with Senior Editor Seyth Miersma. Last time, our chosen sides were eerily similar in design, albeit quite different in actual execution. This time, our vehicular peculiarities couldn't seemingly fall any further from one another: A 1980 Oldsmobile 442 wouldn't seem to match up in comparison to a 1989 BMW 635CSi.
How did we come up with such disparate contenders? Simple, really. Seyth and I mutually agreed to choose a car that's currently for sale online. It had to be built and sold in the 1980s, and it had to be a coupe. The price cap was set at $10,000. The fruits of our searching labors will henceforth be disputed, with Seyth on the side of the Germans, and myself arguing in favor of the Rocket Olds. Am I setting myself up for another lopsided loss?

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.
