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.

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.

Why BMW doesn't plan to integrate Apple's iOS in the Car

While watching Apple introduce iOS in the Car during its WWDC keynote on Monday, we wondered how automakers, even the 14 who've already signed up to integrate this new in-car functionality of iOS 7, will feel about having the Cupertino company's mobile operating system supplant their own in-car systems. After all, some OEMs like Ford, General Motors and many luxury automakers have sunk millions of dollars into developing their own advanced infotainment, navigation and communication platforms like MyFord Touch, CUE and older systems like iDrive.
One automaker has now spoken up. A BMW spokeperson was interviewed by someone in the news department of British auto dealer group Arnold Clark and confirmed that the company would not be getting in line to integrate iOS in the Car anytime soon. The reason, as we suspected, is that BMW believes its own products developed over the last decade are both plenty good and already so deeply integrated with other systems of the car that, as told to Arnold Clark, "it would not be that straightforward to start changing all of the architecture of a car as has been implied [by Apple]."
While BMW isn't interested in spending more money to integrate Apple's services and functionality over its own, it has spent a good bit already to integrate iPhone functionality in its cars, including the relatively rare ability to support iPod Out and display Apple's own interface on Mini models with the optional Mini Connected feature, as well as committing to integrate Siri 'Eyes Free' functionality.
