Owners of any 964-generation Porsche 911 can have their car turned into the Ruf RCT of the 1990s thanks to a new restomod service from the German tuner. You'll get an air-cooled, turbocharged flat-6 just like in the original, along with modern upgrades of your choosing including a full carbon-fiber body.

The Mercedes-Benz GLS is a posh ride but a more luxurious version from Maybach is now available. It's designed to target the Bentley Bentayga and Rolls-Royce Cullinan, and after spending some time with one, we can confirm that it definitely looks and feels the part.

BMW has been spotted testing a new flagship SUV related to the X7 and likely to be badged an X8. It won't simply be a coupe-like version of the X7 as our spy shots reveal. Rather, it will be more like what the X2 is to the X1.

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