BMW M3 and M4 CSL not in the cards

We aren't sure whether to file this one under "good news" or "bad news." BMW confirmed to Top Gear that there "are no plans" for lightweight versions of the new M3 and M4, in the same vein as the E46 M3 CSL (despite rumors to the contrary). The reason?
"There wasn't a CSL on the previous generation, and the way we look at it is like this: the CSL was great because it had this real focus on lightweight engineering. But we've already done that with these new cars. We've made them as light as possible - they come in under 1500 kilograms (3,306 pounds), which for a car like this is incredible," said Matt Collins, BMW's product manager for small to medium cars.
Now, as much as we love the idea of a hardcore version of any car, we appreciate BMW's point of view that the newest Ms are already as light and tough as they need to be. Collins elaborated, saying, "Rather than doing a halfway house to begin with and then rolling out a CSL, we thought we'd make the 'real' car as light as we possibly could. So we've no plans whatsoever to make a lighter, harder version just yet."

2015 BMW Alpina B6 xDrive Gran Coupe priced from $118,225* [w/poll]

If you're in the market for a high-performance BMW and you live in Europe, you've typically had two range of options at your disposal: you could go for one of BMW's own M models, or turn to Alpina. Though technically independent of BMW, Alpina is about as close to the manufacturer as a tuner can get, and many of its models are offered through BMW's own dealer network.
That's overseas, but in the North American market, BMW has typically taken a different approach, offering just one Alpina model - the B7 - to fill in for a lack of M7 performance sedan. That all changes, however, with the debut of the BMW Alpina B6 xDrive Gran Coupe.
Slotting in alongside the M6 Gran Coupe, the Alpina B6 xDrive Gran Coupe is marginally more expensive and slightly less powerful, but makes up for those relative (and negligible) shortcomings in spades. Both are based on the 6 Series Gran Coupe and both pack a 4.4-liter twin-turbo V8, but with key differences. Where the M6 produces 560 horsepower, the Alpina offers 'only' 540. But where the M6 channels 500 pound-feet of torque to the rear wheels through a seven-speed dual-clutch transmission, the Alpina drives 540 lb-ft to all four wheels through an eight-speed automatic.

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.
