McLaren has teamed up with Lanzante to build a successor to the legendary F1 LM based on the P1 GTR track car. Just six are being built and one of those cars, a prototype, has been spotted testing on the Nürburgring.

Mercedes-Benz is in the process of overhauling its engine lineup. The overhaul includes replacing the current assortment of V-6 engines with new inline-6 engines delivering V-8-like performance.

Porsche’s second-generation Panamera will be getting a wagon body style—including here in the United States. A barely disguised prototype has been spotted on the ‘Ring and reveals the handsome new look.
