The 2017 model year is the last for the Dodge Viper supercar. To send it off into the sunset, Dodge is launching a series of special edition models. Most of these are already sold out but you can still order the regular version of the car, including the track-focused ACR.

Mercedes-Benz is working on a mid-cycle update for its S-Class range. Over the weekend we saw spy shots of a prototype for the updated version of the S63 from Mercedes-AMG. The car appears to be adopting some visual tweaks in the front bumper.

Another spied vehicle is Porsche’s redesigned Cayenne. The SUV looks to be adopting a sportier look. Its powertrains, meanwhile, should be shared with the redesigned Panamera, which the new Cayenne will trail by about a year.

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