After a brief tease, BMW lifted the veil from the 2019 BMW 8-Series lineup, which includes a coupe and convertible model. The 2020 BMW 8-Series will usher in a whole new variant with a few extra doors.

We expect the 2020 BMW 8-Series to continue offering the coupe and convertible variants with minimal updates, but the big news will be the debut 2020 8-Series Gran Coupe. This new four-door 8-Series will boast the same low-slung, aggressive-looking face and hood as the coupe and convertible models, but it will be a different rig from the windshield back. The biggest changes will be to its size, as the 8-Series Gran Coupe will be 9 inches longer, 1.2 inches wider, and 2.2 inches taller than its coupe sibling. Add to that a 7.9-inch-longer wheelbase to better accommodate rear passengers.

Inside, the 8-Series Gran Coupe will pay tons more attention to the rear-seat passengers, giving them more robust seats combined with an extra 7.1 inches of legroom, 7.7 inches of shoulder room, and 3.4 inches of headroom. Front-seat passengers will also get an extra 0.2 inches of headroom, and trunk space will grow by 0.7 cubic feet. Rear passengers will also get two independent seats split by a small center seat you can use in a pinch for a fifth passenger and independent climate controls, air vents, storage tray, and USB-C ports.

The cabin will feature tons of modern and upscale goodies, including a 12.3-inch digital gauge cluster and driver-information center, a 10.25-inch central infotainment screen, iDrive, cloud-based voice control, gesture control, navigation, Apple CarPlay, a 16-speaker Harman-Kardon audio system, Nappa leather seating, wireless charging pad, Wi-Fi, and tons more.

The 2020 BMW 8-Series Gran Coupe will have a pair of powertrain flavors, starting with the 840i and its 3.0-liter turbocharged inline-six engine that pumps out 335 horsepower and 368 pound-feet of torque. This will launch the 840i to 60 mph in 4.9 seconds. Adding optional xDrive all-wheel drive will drop the sprint time to 4.6 seconds.

Moving into the M850i xDrive will add a 4.4-liter twin-turbo V8 with 523 hp and 553 lb-ft of torque that will rocket the Gran Coupe to 60 mph in just 3.7 seconds. Both engines will pair with an eight-speed automatic transmission.

Neither the NHTSA nor the IIHS has tested the current 8-Series, so the jury is out on just how safe the 2020 8-Series Gran Coupe will be. What we know is the 2020 8-Series Gran Coupe will come standard with forward-collision warning with automatic emergency braking. It will also have a slew of optional driver-assist features like blind-spot monitoring, lane-departure warning, 360-degree camera, parking assistant, rear cross-traffic alert, speed-limit information, and more. At the very least, the 2020 8-Series Gran Coupe will have the safety features needed to be an IIHS Top Safety Pick.

The 2020 BMW 8-Series Gran Coupe is due to be released in September 2019.

Official pricing will start from $85,895 and the range-topping M850i xDrive will start from $109,895 ($995 destination fee included).

The 8-Series will compete with the Mercedes-Benz S-Class, Audi A8, and Porsche Panamera.
