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.

Why you can expect lots more crossovers from BMW

BMW is becoming the ultimate crossover sales machine. More than a third of the German brand's US sales in 2015 were crossovers, and the automaker expects 40 percent of 2016 sales to be the all-purpose runabouts. What's more, BMW of North America CEO Ludwig Willisch said that when the X7 gets here the percentage will take another leap. Even though BMW was one of the automakers to raise warning flags about how China's depressed car market would impact earnings, the Willisch said the Munich brand couldn't get enough of the X1, X3, and X5 in the first three quarters of 2015 in any of its key markets. Remedy is on the way with an expansion of the Spartanburg, SC plant. When it's finished later this year the US factory will be able to build 29 percent more product than before, annual capacity rising from 350,000 to 450,000. Spartanburg currently builds the X3, X4, and X5. There's every reason to believe that BMW will post another record US sales year in 2015, adding a lot of fat to its profit statement in what should be a record year overall. TrueCar predicts 17.5 million light vehicle sales in the US last year, a 6.1-percent increase over 2014. BMW could also take the luxury crown after posting a monster month of December sales, we'll know when the numbers are reported this week. The huge numbers have come with the help of incentives. BMW spent slightly more than competitors Mercedes-Benz and Lexus, but only fractionally up on 2014 incentive spending.

History of BMW touring cars looks splendid in Adrenalin trailer

More high-quality documentaries about the history of motorsports are always welcome. When thinking about racing, we generally focus on moving forward to go a little faster or shave a tenth of a second off a lap. There's not much time to look backward. It's too bad, because there are so many fantastic stories from the sport's history. Thankfully, an upcoming doc is taking on the challenge of telling some of these tales, and it looks like a movie not to miss, especially for BMW fans.
Adrenalin - The BMW Touring Car Story mixes high-quality, vintage footage with new interviews from many of the drivers of these machines to craft what looks like a fantastic experience. Covering the period from the '60s to the modern DTM era, just the trailer shows racing from the 2002, 3.0 CSL and of course the E30 chassis M3 of the '80s. You also get to hear from legends behind the wheel like Hans-Joachim Stuck, Johnny Cecotto and Joachim Winkelhock telling their stories.
Adrenalin comes out in November on DVD, Blu-Ray and on-demand. Check out its trailer above for a taste at what it's aiming for. The documentary definitely looks like one to watch.
