Three and a half decades ago, BMW created the definitive luxury super sedan with the M5. To celebrate the model’s 35th birthday, BMW debuts the limited-production “Edition 35 Years” M5 for 2020. Based on the high-performance M5 Competition, the Edition 35 Years distinguishes itself with special Frozen Dark Grey II paint, 20-inch alloy wheels finished in Graphite Grey, high-gloss black brake calipers, and badge delete on the trunk. There are more special touches on the inside, such as black leather M Sport seats with contrast beige stitching, “M5 Edition 35 Jahre” engravings on the door sill plates and center console, and a gold anodized finish on the center console, door trim, and instrument panel. The Edition 35 Years also comes standard with the otherwise optional Executive Package and M Driver’s Package. Production is limited to 350 units worldwide. The rest of the M5 lineup consists of either Standard or Competition trim. All M5s come with a 4.4-liter twin-turbo V8. In the standard car, the engine makes 600 horsepower and 553 pound-feet of torque and pairs with an 8-speed M Steptronic transmission. The Competition features the same engine but with 617 hp and 553 lb-ft. An M Driver’s Package, which comes standard on the Edition 35 Years trim, raises the electronic speed limiter from 155 mph to 189 and includes a voucher for an M Driver’s School session at one of the BMW Performance Centers in the US. Although the M5 is a large, comfortable sedan, it’s also track-capable with a transmission oil cooler, an active M differential, and optional carbon-ceramic brakes. The M5 Competition sits about 7 millimeters lower than the standard car and has stiffer suspension. The EPA rates the M5 at just 17 mpg combined. The base version gets wireless-device charging, a Harman Kardon stereo, leather upholstery, and 20-way power heated front seats. The Executive Package, which comes standard on the Edition 35 Years M5, dresses things up further with soft-close doors, a power rear sunshade, ventilated front seats, heated rear seats, 4-zone automatic climate control, and a surround-view camera. The M5 comes with BMW’s latest iDrive 7 operating system as well as a 12.3-inch digital instrument cluster and a 10.25-inch center display. The M5 hasn’t been crash-tested on its own, but the standard 5 Series, on which the M5 is based, gets the highest available Top Safety Pick+ status from the Insurance Institute for Highway Safety (IIHS). The M5 also comes standard with blind-spot monitors, lane-departure warning, forward-collision warning with automatic emergency braking and pedestrian detection, and a head-up display (HUD). Adaptive cruise control and adaptive lane control are optional extras. The Mercedes-Benz E 63 AMG S and Porsche Panamera Turbo are both equally ferocious 4-doors that compete with the M5.
