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.

Alpina B3 Bi-Turbo offers Europeans a pre-M3 performance 3er

Anyone that's spent some time behind the wheel of the Alpina B7 probably knows enough to understand what Americans are missing with this, newly launched Alpina B3 Bi-Turbo. We've got no lack of M models to choose from, it's true, but the Alpina touch offers a completely different driving character, with almost as much performance. A pity then that Alpina has no plans that we've heard of to bring this one across the pond.
Filling the gap between the current 3 Series offerings and the outgoing M3 (we're not likely to even see the new M3 and M4 until September's Frankfurt show, nor be able to buy one until after that), the B3 Bi-Turbo brings serious performance to the F30 3er. As the name indicates, two turbochargers are used to force-feed BMW's 3.0-liter inline-six engine, for a total output of 410 horsepower and 442 pound-feet of torque. That power offers a big jump from even the BMW 335i sedan, and will push the B3 to 62 miles per hour in just 4.2 seconds and on to a top speed of 190 miles per hour. Alpina's own sport suspension underpins the thing, while the power is modulated by way of a eight-speed automatic transmission.
The new B3 will be easily recognizable thanks to its "Classic" 20-inch, 20-spoke Alpina wheels, and a rather subtle, aero-enhancing body kit. No pricing has yet been announced, but you will find a host of additional information in the attached Alpina press release below.

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.
