Overview
The 2025 BMW 8 Series Coupe and Convertible are BMW’s large luxury 2-doors, topped by the hardcore M8 variants, which we review separately. The regular 8 Series models start with the 335-horsepower turbocharged inline 6-cylinder 840i, but you also have access to an M850i xDrive with a 523-hp twin-turbo V8 and 523 hp. Both body styles offer true grand touring with a sporting bent. All are all-wheel drive, except for the base RWD 840i. With the M Sport package standard on all trim and Merino leather in the cabin, the 8 Series represents flagship BMW sporting values in a svelte 2-door format.
What’s New for 2025?
The 8 Series has continued mostly unchanged since its 2023 refresh, and the 2025 model follows suit as a carry-over from last year. The 2025 BMW 8 Series’s price is the only thing that changes, increasing by just over $2,500 at the base level.
Exterior
The 2025 8 Series sits low to the ground, with a wide, aggressive stance, muscular haunches, slim Icon Adaptive LED headlights, and a prominent but flat kidney grille, not the controversial bucktooth item on the 4 Series. The M850i looks subtly sportier with its front spoiler attachment, the M exterior mirrors originally used on the M8, and an M rear spoiler (coupe only).
The 840i runs on 19-inch alloy wheels, while the M850i upgrades to 20-inch Y-spoke M alloy wheels with staggered performance tires. The Convertible’s fully electric soft top opens or closes in 15 seconds at speeds up to 30 mph.

Interior
Merino leather upholstery is standard, and extended leather for the door panels and dashboard is available. The cockpit is driver-centered, and the wide center console rises toward the dashboard, topped by a 12.3-inch touchscreen still running the older iDrive 7. The driver faces a digital gauge cluster of the same size, so this isn’t one of the newfangled BMW interiors with the big curved single-piece display and newer iDrive systems.
Both body styles are 4-seaters with two sculpted rear seats, suited to kids only, with only 29.5 inches of legroom and around 34 inches of headroom. A 16-speaker Harman Kardon audio system is fitted, but you can upgrade to a 1,400-watt Bowers and Wilkens setup.

Pros and Cons
Pros:
- M850i’s 523-hp V8 hits 60 in 3.6 seconds with effortless refinement
- Merino leather, M Sport package, and Harman Kardon audio are all standard
- Convertible’s soft top operates in 15 seconds at up to 30 mph
Cons:
- Rear seats are tight and best for occasional use only
- M850i’s 19 MPG combined is thirsty for a grand tourer
- May be discontinued, limiting future resale confidence
Verdict
The BMW 8 Series Coupe and Convertible are the reserve of the few who can splurge on an impractical luxury 2-seater, and you don’t even need to spring for the V8 to make the most of it. The superb 840i comes with BMW’s signature inline six-pot and will still get you to 60 mph in well under five seconds and return a respectable 24 mpg. The M850i may be the soul of the lineup with its sub-four-second sprint and V8 soundtrack, but it’s not the best-value buy overall.
The ride is composed, even on the 20-inch wheels, and the cabin cossets you in the lap of luxury, even though you can see it’s an older BMW interior without the latest digital cockpit with its huge, continuous display. The Mercedes SL may be more flashy, and the Porsche 911 sharper dynamically, but the 8 Series is an excellent blend of comfort and sport. This may also be its last model year, so you don’t have long if it ticks all your boxes.
