BMW says current M3 sold out, no new AWD M models planned

Car and Driver asked the head of BMW M, Friedrich Nitschke, a few questions about what the go-fast division had in mind for the future, and was rewarded with some enlightening answers. The best news to purist ears is that Nitschke said customers don't want all-wheel drive on their M cars, so it's the rear wheels alone that will propel new product into the future. If you want both an M badge and four driven wheels, it's the X5 M, X6 M and M Performance models you're looking for in the catalog.
"Mixed bag" is the phrase you're looking for regarding the other answers. Nitschke said that future M engines "at the core of their architecture" would "be closer to BMW AG engines" that are optimized for M cars, instead of following in the line of unique marvels like the V10 and naturally aspirated V8. They will keep the high redlines, however, with Nitschke saying "there is room beyond" the 7,000 rpm mark in BMW's current V8 turbos.
Managing weight will keep the same priority for M that it is for every other brand, so electrically assisted power steering is coming, as is an "unconventional" materials mix. At the smaller end of the M scale, Nitschke described three-cylinder engines as "attractive," saying that the brand can produce more than 310 horsepower from a three-pot.

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.

BMW i8 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.
