Four Possible Versions Of The BMW M3 Engine

According to unofficial information published m3post.com, BMW had to choose for the next generation M3 will be launched in 2013, one of only four possible versions of the engine.

The first possibility would be mounting a bi-turbo TwinPower 4-liter V8 (S65) of the current generation. The advantage would be that such power would be added to a respectable and impressive torque to the current configuration, while preserving fuel to an acceptable level.

A second option would be N55 or N54, 3-liter engine with six-cylinder BMW that you can configure either a single turbine (N55) or for two (N54), TwinPower technology to provide multiple versions of power. Configuration would of course be modified to provide at least 420 horsepower. This version is the main cost advantage, the engine is already offered on other BMW models.

The "crazy" option would be for the Bavarians to "squeeze" under the hood, the 4.4-liter V8 unit will be offered for future generation M5 and M6. Engine power could be easily reduced to M3, but this version is not very appealing at least two reasons. First, fuel consumption is very high (counter-opinion that now promotes BMW) and in addition, this engine could be mounted on the Z4 (Bavarians want to reduce costs by offering some of the same engine for the two models).

Finally, the last option would be - those who were on the wall a poster of M3 can not read "blasphemy" that follows - mounting a V6 engine based on the S63 unit. Well, it seems that this version is even the favorite of BMW, and although it is unknown how many turbines will be installed on this engine.

What do you think is the most plausible version?
