BMW switching to turbocharged M cars
After two decades of normally-aspirated high-revving engines shoehorned under the hoods of its M cars, BMW is changing direction and will begin to offer direct-injection turbocharged powerplants in its future high-performance flagships. The German automaker is blaming tough environmental emission standards and the soaring manufacturing costs of the specialty-built V8 and V10 engines found in today's M3, M5, and M6 models for its decision. We also suspect the fact that both Audi and Mercedes-Benz have successfully offered torque-laden forced-induction powerplants for years on their performance models may have something to do with it (also keep in mind that an aftermarket-tuned version of BMW's own twin-turbo 3.0-liter inline-6 can easily match the power output of the M3's normally-aspirated 4.0-liter V8). The first new M model to carry the turbocharged honor will be the X6 xDrive M, with a twin-turbo 4.4-liter V8 reportedly making 500 hp and 516 lb-ft of torque. That same engine is reportedly going into the next F10-chassis M5 due in late 2010.

The 2010 M5 will have less horsepower and less torque than the 2009 CTS-V?

Mercedes will begin phasing out V12 engines
Mercedes-Benz, longtime stalwarts of the V12 engine, is considering lowering its preferred cylinder count by a third. While our first inclination is to assume that this change is being made to increase the fuel efficiency and lower the emissions of the overall Daimler line, the real reason that the bent-12 engine program is being dropped is simply because the block is too long. A V12 is, for all intents and purposes, the same length as an inline-six, and the German automaker's latest line of mainstream engines are all in a V-design, so its cars are no longer being designed with an engine compartment large enough to house such a lengthy engine. Fear not, power fans, as the company isn't abandoning high horsepower in general. The V12 program is apparently being shifted towards twin-turbo V8s, and the magic of forced-induction means there's no reason to assume that fewer cylinders will equal fewer ponies. Expect the moratorium on V12s to begin the next few years.
