FAST FACTS
"Is the M8 Gran Coupe overkill, given that the 'regular' M850i xDrive Gran Coupe with its fire-breathing 523-horsepower V8 already exists? Well, yes, obviously — but that's also the point. This segment is all about excess, and the M8 Gran Coupe is a 617-hp monument to it. Although the M8 GC is, like the M5, unusually long for a midsize sedan, we daresay it's the better driver's car, as it uses essentially the same twin-turbo V8 without any of the PHEV frippery, saving hundreds of pounds. Looks a lot better, too."—Ranked #4 out of 5 Midsize High-Performance Sedans
MotorDonkey's proprietary vehicle data identifies every significant version of each model so that you can compare and decide. There's only one standalone version of the 2025 BMW M8 Gran Coupe, and here it is, along with our expert analysis and recommendations.
Comparing the M8 Competition Gran Coupe to the Alpina B8 (another aggressively priced variant of the 8 Series Gran Coupe), it's notable that the M8 is a few hundred pounds lighter, which explains why its acceleration is better. The M8 also has a larger fuel tank than the other 8 Series Gran Coupe variants, which is nice given that its fuel economy is the lowest of the bunch. And speaking of price, the M8 is more than $10k cheaper than the B8 Alpina. The problem is that it's still way more expensive than the very similar M850i Gran Coupe.
