BMW is working on a new 8-Series that will spawn a high-performance M8 variant. There will also be an M8 race car competing in the World Endurance Championship and United SportsCar Championship, and judging by the camouflaged prototypes it’s going to be a mean machine.

Buick has just unveiled a new generation of the Regal GS. But North America and China won’t be the only recipients of the car this time. The Regal GS will also be sold in rebadged form in markets where Holdens, Opels and Vauxhalls are sold.

Even in standard form, the Porsche 718 Boxster is a brilliant car. However, Porsche is cooking up more potent versions and the first of these will be a new 718 Boxster GTS. Prototypes for the car have just been spotted.
