BMW M4 to debut in Detroit, lose manual transmission

BMW took the wraps off its M4 Concept at Pebble Beach last weekend, and many speculated that the highly anticipated production version of the sleek new two-door sports coupe would debut at the Los Angeles Auto Show later this year. But a well-placed source tell Autoblog that the E92 M3's successor won't arrive in Southern California this November. Instead, the German automaker will wait until the Detroit Auto Show in January for its first official reveal.
An all-new 3.0-liter inline-six with twin turbochargers is expected under the hood, and it should provide about the same horsepower as the current 4.0-liter V8 (rated at 414 horsepower), but with much more torque that arrives lower on the tachometer. The lightweight engine is said to have an impressively high redline, which is unusual for a turbocharged engine.
Unfortunately, Save the Manuals members aren't going to like this next bit of news. After four generations of three-pedal M3 models, our source says the upcoming F82 M4 will arrive with a dual-clutch transmission (DCT) as standard equipment - with no manual option - just like the latest iteration of the track-ready Porsche GT3 (few have complained about the automaker's PDK after driving the latest sports car from Stuttgart). In exchange for some moans, groans and gripes from enthusiasts, BMW's DCT mounted aft of the M4's inline-six will provide quicker acceleration and improved fuel economy.

This is the BMW Z4 GTE that will wear the Roundel in ALMS

The Speedweeks at Daytona International Speedway are a month of racing and reveals, with the season's metal going for the flag at races like the Rolex 24 at Daytona and other cars being introduced to the public. In the latter category is the BMW Z4 GTE (click the image above to enlarge) joining the American Le Mans Series GT class this year with BMW Team RLL (Rahal, Letterman and Lanigan). This machine replaces the M3 GT that completed four years of service and won the class title in 2010 and 2011. Naturally, the team is tempering expectations for the Z4 GTE by repeating the fact that it sees this season as a development year.
BMW Team RLL drivers for its two cars will be Bill Auberlen and series rookie Maxime Martin in the No. 55, aided by Jörg Müller for the endurance races at Sebring and Road Atlanta. The No. 56 car gets Dirk Müller on a full-time basis, Joey Hand when he's not competing in the DTM series, and John Edwards when Hand isn't available. Uwe Alzen will help out with driving duties in the No. 56 at endurance races.

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.
