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.

2014 BMW M6 Gran Coupe

Is This A Great Idea For An M Model?
The BMW 6 Series Gran Coupe is already an issue of large debate. The essential business case for the car is that it's more distinctive than a straight 5 or 6 Series, and has much of the sense of space and luxury of a 7 Series. It has the wheelbase of a 5 Series, the relative width of a 6 Series, and an exterior length close to the standard wheelbase 7 Series. And, as we reported in our drive of the 640i Gran Coupe in May 2012, the 6 Series Gran Coupe costs pretty much the same as the 7 Series, engine trim for engine trim. The sedan (coupe?) is therefore a proposal clearly meant for an extremely particular clientele. There's no news yet on how well exactly the 6 Series Gran Coupe is selling in its chief markets, but we are curious. The Germans frequently tend not to break out their sales figures that way, mixing sales of the Gran Coupe in with the two-door 6 Series.
And, so, we have now arrived at the inevitable point where the M version must be introduced. Say howdy to the $113,000 2014 BMW M6 Gran Coupe (actually $115,195 for starters with all of the taxes added). That's $4,650 more than the also highly priced M6 coupe. Let the vehement debates begin. The upcoming 2014 Audi RS7 should be priced right at this level as well, and the Mercedes-Benz CLS63 AMG (perhaps with an S iteration in the next allotment we get Stateside) should go for roughly the same.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
