2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

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.
