The M8 and M8 Competition are very similar on the surface, with Competition badges and unique wheels being the only exterior hint at the improvements beneath the skin. Both models share a 4.4-liter twin-turbo V8, with the base M8 producing 600 hp and the Comp managing 617. As standard, both are equipped with adaptive LED headlights and taillights, adaptive dampers, and a customizable exhaust system. Both feature 16 speakers inside, and a head-up display, as well as variable drive modes for road and sport - although the Competition model adds a track setting. It also gets a stiffer suspension, recalibrated electronics for more intense performance, more front camber for better turn-in, and an M-Sport exhaust. Both feature 20-inch wheels, with the Competition pack getting access to a unique design. Both models also get 12 exterior color options, four trim choices, and eight Merino leather upholstery variations.
