BMW’s M4 is about to undergo its mid-cycle update. A prototype has been spotted and reveals that some of the changes will include a few parts lifted from the high-performance M4 GTS.

A car that has just been updated is Audi’s S3. Unfortunately there’s no extra power on offer for cars in the United States, but as some solace Audi will offer a much more powerful RS 3 in the not too distant future.

The Fisker Karma is making a return as the Karma Revero. The new extended-range electric sedan has been revealed today, and while its styling hasn’t changed much there is said to be a number of mechanical mods.

You'll find all of these stories and more in today's car news, right here at Motor Authority.
