The BMW //M cars have been powered for nearly twenty-years by normally-aspirated modified engines giving the buyers higher-revs and more horsepower. For the past few years, BMW has been focusing on their turbo and twin-turbo technology building engines that won them several awards.

In a recent interview with BMW’s Director of European Delivery, Keri-Lynne Shaw, it was confirmed that the amazing 3.0 liter twin-turbo engine found across BMW’s series, had a huge impact in the recent sales. There were also several reports of BMW moving away from its V8/V10 engines due to emission standards and manufacturing costs and replace them with smaller, more efficient ones.

So, it was no surprise when Autoweek and Autoblog reported BMW’s decision to steer away from the large naturally-aspirated engines and replace them across their //M models with twin-turbo engines. It is known that many tuners managed to take the 3.0 liter twin-turbo to the levels and power of a 4.0 liter V8(M3’s engine these days).

The first model to take advantage of the turbocharged engines is the controversial BMW X6M, a car that will be powered by a 4.4-liter V8 twin-turbo outputting 500 ponies and 516 lb-ft of torque.

As a BMW enthusiast, I’ve grown with the M engines and always loved them, so it will be interesting to see how the new engines will be received by the picky BMW fans.

What do you guys think? Naturally aspirated V8 or twin-turbo V8? Cons/Pros?
