2014 BMW M3 Will Have Twin-Turbo V6
For a while now, it has been speculated that BMW is simultaneously testing both a straight-six and a V6, to find out which suits the attitude of the car better. But according to Inside Line, this is no longer the case as a highly advanced V6 is the engine chosen.
The reason for this is simple: the V6 is better when it comes to packing it into the car’s body. The two twin-scroll turbos will be mounted within the V of the engine. “This unique-to-BMW approach reduces the length of the inlet tract compared with a regular turbo-vee setup, helping to sharpen throttle response and minimizing heat buildup after air passes through the intercooler,” Inside Line says.
The engine won’t be a chopped version of the V8 twin-turbo in the M5 and M6, as the insider says it will not be a 3.3-liter but a completely new 3.0-liter. Power will be boosted to 429 horsepower and 405 pound-feet of torque, but the biggest improvements will be to the efficiency of the car.
