F82 M4 tagged posts

According to BMW insider, after the release of the M2 next year, the next exciting news for the M brand is the GTS model of the M4.

For your reference, the GTS trim is a more track-oriented variant, it usually deletes some non-necessary parts and incorporates structural enhancements. For example, the E92 M3 GTS weights approx. 300 lbs less than the standard M3. Of course, there may be other upgrades to the powertrain, suspension and braking system.

Currently there is no further information about the M4 GTS, we will keep an eye on it and report back any updates.

The S55 engine-equipped 2015 BMW M3 and M4 has been for sale for a while.

However, before looking at the below two technical documents from BMW, I bet you do not know the M3 and M4 in such depth. These two official documents provides precious details about these M cars and its heart: the S55 engine.

For example, some of the major differences between the S55 engine and the N55 engine (which is found in all BMW *35i models), are: 1. the S55 has closed deck crankcase, and the N55 is open deck; 2. the S55 has LDS-coated aluminum cylinder liners, while the N55 is using cast iron liners.
