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.

Dinan S3-R BMW 1M Coupe

I nearly shed tears a few years ago upon learning that BMW was only planning to produce a very limited quantity of its then-new 2011 1 Series M Coupe. In simplest terms, the two-door was a 1 Series fitted with a modified version of the automaker's twin-turbocharged 3.0-liter inline-six, and the running gear (gearbox, driveshaft, axles) from contemporary M3 models. It was also a return to form for the brand. Aggressively short and stubby in stature but packing telltale flared wheel arches that hinted at its potential, the four-seater was a spiritual successor to the original (and much loved) E30 M3 from decades earlier.
After spending a day with the original high-performance 1 at New York's Monticello Motor Club, I declared, "The little coupe with the big flares is old-school retro cool and deliciously fun to drive ... the new BMW 1 Series M Coupe doesn't target boy-racers, it targets enthusiasts." Yet sadly - and despite strong demand - BMW limited the model's production to just one year. All told, only 740 units made it to the States, and each was gobbled up at a starting price of $46,135, a price tag history will show to be a bargain.
Since I had little hope of even driving one again, I deliberately pushed all memories of BMW's 1 Series M Coupe from my mind - until my phone rang recently. On the other end was a representative from Dinan Engineering who wanted to know if I would be interested in driving the company's new S3-R BMW 1M. A quick Google search revealed it to be a heavily modified version of the discontinued 1 Series M Coupe. As if they needed an answer...

First Ride: 2015 BMW M3 and M4

Getting Our Butts In The Seats
Both the non-M BMW 3 Series sedan and 4 Series coupe have so far brought much pleasure to us at Autoblog. The terrific four-cylinder 328i trim has become our favorite of the 3 Series line, while we have yet to get a chance at the 428i coupe. That said, the 35i trim powered by a 3.0-liter TwinPower Turbo inline six-cylinder engine is not exactly to be sniffed at.
We all know the ones you're really waiting for, though. The F80 fifth-generation M3 sedan and the supremely sexy F82 M4 coupe. Rumors have been buzzing for a couple of years now that the engine would be another V8, only turbocharged this time, or else a tri-turbo six. Well, today BMW confirmed that the mill under the hood's power bulge is a 3.0-liter inline six-cylinder TwinPower Turbo of the biturbo variety, referred to internally as "S55B30 variant."
