The Alpina B8 Gran Coupe shares its body with other Gran Coupes, but there's quite a bit more individuality. The distinctive 21-inch Alpina alloy wheels and blue brake calipers mark it out as something special. These wheels can be exchanged for 20-inch items wearing all-season tires if you wish. Compared to a normal GC, there are other differences too. The air intakes in the front bumper are larger, and at the rear, you'll notice a black diffuser, Alpina B8 badging, and a subtle color-coded decklid spoiler. Unlike the round items on an M8 GC, the oval outlets here identify the signature Alpina exhaust system. And where the non-Alpina model has a fixed carbon-fiber roof, the B8 has a panoramic power-sliding and tilting moonroof with a sunshade by default; the carbon roof is still optionally available. Most exterior trim, save for the illuminated grille, gets the blacked-out Shadowline treatment, but you can opt the Chrome Line trim back in if you prefer it.
With a length of 200.5 inches, a width of 76.1 inches (84.1 with the mirrors), and a height of 56 inches, the BMW Alpina B8 Gran Coupe's dimensions are substantial, but on par with the M8 GC on which it's based - the only difference is the M8 GC is almost half an inch longer.
The Alpina B8's svelte body is stretched over a 119-inch wheelbase and, thanks to the xDrive drivetrain, extensive spec sheet, and substantial footprint, it weighs in at a considerable 4,831 pounds. Its size and weight are in the same ballpark as rivals such as the Audi RS7, and around 350 lbs more than the standard M8 GC.

There are 15 exterior colors for the 2023 BMW Alpina B8 Gran Coupe, of which two are no-cost Alpina-exclusive colors, namely Alpina Blue Metallic and Alpina Green Metallic. There are eight other colors carried over from the M8 GC's palette with a few new names for 2023; the list includes Alpine White, Mineral White, Carbon Black, Black Sapphire, Sunset Orange, Portimao Blue, San Remo Green, and Skyscraper Grey. Tanzanite Blue II, Aventurin Red, and Dravit Grey are $1,950 metallics. Two matte colors, Frozen Pure Grey and Frozen Tanzanite Blue, cost $5,000 extra. We would opt for one of the two Alpina colors for that final measure of exclusivity.
Shown off in many of the B8's press photos, the stunning Alpina Green Metallic is our favorite. It's an Alpina-exclusive hue that you won't see on any mainstream BMW, and instantly indicates that Alpina has worked its magic. As a bonus, it's also free.
The standard wheels are 21-inch trademark Alpina 20-spoke items with covered lug nuts and performance tires. However, smaller 20-inch Alpina wheels with exposed lug nuts and all-season tires are optionally available at no extra cost.
The Alpina Gran Coupe has four tailpipes, just like the M8 Gran Coupe, but unlike the M car, they are oval and not round and sit in a differently styled lower valance.
Unlike the M8 Gran Coupe, which has a fixed M Carbon roof with no available sunroof, the Alpina B8 has a powered glass panoramic moonroof that can slide and tilt as standard. However, you can still order the M Carbon roof for $2,800, but this is a fixed roof that cannot be fitted with a sunroof.
