BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

BMW working with Dainese to put airbags in motorcycle suits [w/video]

Addressing the safety concerns of its customers, BMW Motorrad is co-developing a rider suit with Dainese to feature something that's much more common in automobiles: airbags.
Starting with Dainese's D-air Protect System, which is made up of inflatable protectors that deploy in 15 milliseconds, the two companies will integrate the technology into a BMW Motorrad brand, one-piece racing suit, the DoubleR RaceAir. Later a different, street-oriented airbag system that can be retrofitted to bikes will be offered to Beemer riders.
The DoubleR RaceAir is expected to be presented at the EICMA motorcycle show in Milan in November, after all required crash testing has been completed.

BMW M3 and M4 leak ahead of Detroit debut

Images of the overhauled BMW M3 sedan and M4 coupe have leaked ahead of a debut at next month's Detroit Auto Show, along with option sheets and some specs.
Both wear the standard hallmarks of BMW's M division. There's a subtle power dome in the hood, along with the requisite M3/4-branded strakes on the front fenders. The front and rear fascia are more aggressive than what we've seen in the 3/4 Series M Sport package, as well. Split-five-spoke wheels mean the neither car will stand out in the family portrait and those gold calipers, meanwhile, signify what has been rumored for some time - the M3 and M4 will be getting carbon-ceramic brakes.
The cabin is home to the standard suite of M accoutrements, including a new steering wheel and more heavily bolstered seats. Special trim, including carbon fiber, will be available to further set these cars apart from the standard models.
