Mercedes-AMG has expanded the GT Roadster lineup with the new GT S Roadster. The car has the same 515-horsepower rating as the GT S coupe and will reach 60 mph from rest just as quick.

Dubai's Devel is working on a wild 6x6 SUV to join its 5,000-horsepower Sixteen supercar. The SUV will go by the name Sixty, and a prototype has been shown to accelerate quicker than an AMG GT coupe.

BMW's 8-Series coupe is set to make its debut on June 15 and a new teaser has been released. The debut will take place in Le Mans, where the M8 GTE race car will compete the next day in the 24 Hours of Le Mans.
