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.

2015 BMW i8 Prototype

M Meets Edison
The real telling moment for the new BMW i division will be seeing how the recently tested 2014 i3 sells in its various markets, since that is the car that changes how we perceive our expectations of the brand. But this 2015 BMW i8 green supercar has all the earmarks of a slam-dunk project, we just needed to drive it and make sure for ourselves.
BMW has a spectacular test facility in southern France, called Miramas, and that's where we just had our first brief go behind the wheel of the i8. There were three cars for us there and they were dressed up in exactly the same paisley camo that we've all seen in the spy photos published everywhere for the past year. The interiors, though swathed in masking to hide all the details, varied in their color.

Mazda Turnpike in Japan shut down for racing

The people behind Motorhead Magazine in Japan clearly have some friends in high places. Not only did they manage to shutdown eight kilometers of the Mazda Turnpike up the Hakone mountain, but they invited some of the country's premiere racers to take a drive up the hill. This wasn't just a Sunday cruise either. Featuring a BMW Z4 from the Super GT series, a classic Ford GT40, two flavors of Nissan GT-R and two takes on the Subaru Impreza WRX STI, these guys came ready to run. When an opportunity to let racecars challenge a curvy mountain road presents itself, you don't squander it. Thankfully, the folks at Motorhead knew that and outfitted the course with a plethora of cameras and high-quality sound equipment to capture the action. The result is nothing short of sublime. Take the video's urging to turn up your speakers for this one, and watch as these racers hit ludicrous speeds in a beautiful place never meant for them.
