1985. New Coke came and went. Back to the Future owned the box office. And the first BMW M5 began to rule Germany’s Autobahn. Then powered by a 3.5-liter inline six-cylinder borrowed from the BMW M1 supercar, the '85 M5 was the fastest sedan in the world.
Now in its sixth generation, the 2018 BMW M5 remains one of the world’s quickest, fastest, and best-handling sedans. It’s also the most powerful, most expensive and the most envied version of the BMW 5 Series. BMW’s M division, which is the German automakers in-house hot rod shop, completely redesigned and re-engineered the M5 for 2018. With 600 horsepower, it’s the most powerful M5 ever, and the first time the M5 has all-wheel drive and a traditional automatic transmission with a torque converter. Along with this year's other upgrades, these changes have improved the M5’s performance, safety, comfort, and drivability.
