There's so much afoot in the world of luxury and performance cars this year it's almost impossible to keep pace with it all--but we're doing it so you don't have to. First up in today's news highlights: the 2015 Mercedes-Benz C Class has been spied in testing again, this time revealing its interior, as well as another look at its updated, more graceful exterior.

The Alfa Romeo 4C is getting ready for its global sales launch, and with it, we get a new batch of fantastic photos. Yes, the Alfa 4C really is more beautiful than you thought it was.

BMW isn't one to be left out of the innovation cycle, and the i8 promises to be a rather amazing combination of green and mean--a promise that gains weight with the sound of the sports-hybrid at full throttle.

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