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.

Ferrari, BMW lend expertise to Olympic bobsled, skeleton, luge

LONDON — There are plenty of reasons why the sport of bobsleigh is sometimes referred to as Formula One on ice, but few as obvious as Italy's World Cup sleds. Resplendent in Ferrari red, and with a set of team sponsor Pirelli's P-Zero tyres painted on the sides, they are even liveried to look like racing cars. Ferrari, Formula One's most glamorous and successful team, have worked with the Italian federation, whose sleds run without sponsor branding at the Olympics, since 2010 and in the run-up to next month's Pyeongchang Winter Games. Former rival BMW, title sponsor of the World Cup, has long partnered the U.S. bobsleigh team, while McLaren teamed up with Britain's bob and skeleton athletes for the 2014 Sochi Games in Russia. "There's always the link between the Formula One companies, or any motor company, and skeleton and bobsleigh," says Rachel Blackburn, the engineer who has been involved in Britain's skeleton program since 2006 and who used to work for McLaren. "There's the Ferrari sleds and the BMW sleds ... when we were at McLaren it kind of made a good story," she told Reuters by telephone from her home in Dubai. That somewhat manufactured rivalry has died down in the years since Sochi, with McLaren no longer involved and Ferrari's presence low key. But the worlds of grand prix motor racing and sliding sports still have plenty in common. Bobsled, luge and skeleton are among the fastest of Olympic sports, with bobsleds reaching speeds over 90 mph. Drivers are subjected to gut-wrenching G-forces, and crashes can be fatal. And then there is the ongoing debate about cost controls, the direction of future rules, preserving a level playing field and obsessive secrecy — all endlessly recurring themes in Formula One. 80 mph on a tea tray Blackburn said skeleton, where riders hit 80 mph on what has glibly been compared to an oversized tea-tray, sits somewhere between Americas Cup yachts and Formula One cars in terms of speed and aerodynamics. "Applied engineering is far more interesting than the pure stuff, so when its applied to something that's fun and exciting it does make it a lot easier to solve problems," she said. "There is the Americas Cup, sailing, Formula One and the high speed ice sports as well. It's the same concept.
