Mercedes-AMG’s latest E63 has spawned its wagon variant. The longroof debuts in extra spicy E63 S trim, meaning it’s packing as much as 603 horsepower and 627 pound-feet of torque.

Pininfarina has teamed up with German motorsport firm HWA and two-time Formula One world champion Emerson Fittipaldi to develop a new supercar. It will be revealed at the 2017 Geneva auto show, after which fans will be able to download and drive it in the “Gran Turismo” video game.

Volkswagen has been spotted testing its next-generation Touareg. It keeps a five-seat layout although looks to be wider and more dynamic than its predecessor.
