Which is quicker in a good ol’ fashioned drag race: the hybrid Porsche 918 Spyder or the electric Rimac Concept_One? You can find out thanks to the latest episode of the online show Bangin' Gears.

Another Porsche making headlines today is the 718. The entry-level Porsche sports car is available as a coupe (718 Cayman) or convertible (718 Boxster) and we’ve just driven both. Find out what the cars are like in our first drive review.

There are two noteworthy upgrades for the 2017 GMC Sierra 2500HD. One is the availability of a new Duramax diesel V-8 and the other is the availability of GMC’s All Terrain X off-road package.

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