2015 BMW S 1000 RR looks to retain sportbike supremacy

The BMW S 1000 RR is already a pretty potent member of the superbike ranks, but BMW is revealing a host of upgrades for this two-wheeled lightning bolt at the Intermot 2014 motorcycle show that should make it even faster.
The biggest additions to the latest 1000 RR are its new cylinder head, lighter valves and different intake cam to tweak even more power from the bike's 1.0-liter, four-cylinder engine, and BMW now rates it at a claimed 196 horsepower (or 199 horses if you go with the European measurement, converted from 146 kilowatts), a boost over the first-gen's 193 ponies, and 83 pound-feet of torque through a six-speed gearbox. Those adjustments would probably be enough to make the cycle a tick faster alone, but the Bavarian engineers also cut 8.82 pounds (4 kg) to bring the motorcycle's weight with a full tank of fuel to a feather-light 450 pounds. Much of that diet comes from the redesigned exhaust that cuts about 6.6 pounds off the scales.
Cradling that tweaked engine is a redesigned, lighter frame with fully adjustable springs. The bike also comes standard with Race ABS, stability control, seven-step variable traction control and three riding modes. In terms of styling, all of these changes are communicated through an updated fairing with repositioned, though still asymmetric, headlights.

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.

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.
