BMW makes no significant changes to the 2025 8 Series
Part of the second 8 Series generation introduced for 2019
Overview
When you want your touring to be grand, the BMW 8 Series is ready to travel hastily, and in style. Available as a two-door, four-seat coupe or convertible, the 8 Series is the sportier and more expressive flagship counterpart to the staid and serious 7 Series sedan. Its reason for being is maximum luxury combined with exciting driving dynamics, wrapped in bodywork emphasizing design over practicality. Rumor has it BMW might soon replace the 8 Series with a more affordable 6 Series, so if this is the car you want, don't wait much longer to get it.
Cost to DriveCost to drive estimates for the 2025 BMW 8 Series M850i xDrive 2dr Coupe AWD (4.4L 8cyl Turbo 8A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.95 per gallon for premium unleaded in Wisconsin.
Edmunds spotlight: What is special about the BMW 8 Series?
Made for people with money to spend, the BMW 8 Series represented the pinnacle of luxury and performance when the current-generation model went on sale in 2019. As it did then, the 2025 8 Series comes in three body styles (including the four-door Gran Coupe, which we review separately). Also, in addition to the 840i and M850i models, the car gets the full M division massage when you select the M8 Competition (reviewed separately). Large, powerful, and opulent coupes and convertibles are relatively uncommon today, and to top it off, the 8 Series offers a diverse lineup. That's what makes the 8 Series special.
Competitors to consider
The BMW 8 Series coupe and convertible face few rivals. An equivalent Audi doesn't exist, and Mercedes-Benz has retreated to a lower price class with its latest CLE coupe and convertible models. That leaves the Lexus LC and Mercedes SL as the most likely alternatives to the 8 Series, but they have even less useful back seats than the BMW. The same is true of the Porsche 911 Carrera, but it commands a pretty penny over a BMW 8 Series. Is BMW perfectly positioned with the 8 Series?

edmunds TESTED
The 2025 8 Series convertible excels at long highway journeys. It has a well-constructed interior and a sublimely comfortable ride. It'll entertain you on a curvy back road and keep up with the competition when you leave a set of stoplights, but this Bimmer simply excels at long-distance comfort.
How does the 8 Series drive? The 840i with the base six-cylinder engine has more than adequate power, and the eight-speed automatic transmission delivers smooth, lightning-fast shifts. At our test track, our 840i convertible test car accelerated from 0 to 60 mph in a quick 4.8 seconds. Dynamic back-road driving from this big grand tourer is impressive too, with relatively flat cornering and impressive braking performance.
There are a few drawbacks to the base 8 Series convertible, including heavy but vague steering, poor throttle calibration at slow speeds, and a lack of braking feel. Those are small gripes when you consider the car's overall aptitude.
Comfort
9/10
How comfortable is the 8 Series? The 840i's ride quality is excellent. The adaptive suspension soaks up almost all road imperfections. It's still smooth sailing even in Sport mode. Combine that with one of the quietest cabins in its class, and you've got a car that begs to be taken on a long road trip. The front seats are very comfortable for hours on end. The rear seats are a bit less comfortable, but they're adequate for small children, which is expected in this class.
The buttons for the climate control are a bit confusing at first, but the air conditioning and heated seats work well. The seat ventilation feature, on the other hand, doesn't provide much cooling effect.
Interior
8/10
How’s the interior? The cabin's look and feel are impressive. The primary controls are well placed and require little attention to operate. But there's little room in the back for anyone other than small children. The seats are essentially two nicely upholstered luggage buckets.
The front seats are highly adjustable, so there's no issue finding an ideal position. Visibility is slightly compromised due to the thick pillars and lack of visual references, but the standard blind-spot warning and surround-view camera system help. Overall, none of these drawbacks are unusual for this class.

How’s the tech? The standard audio system is powerful and clear enough that you don't need to bother with the optional (and pricey) Bowers & Wilkins upgrade. But if you're willing to shell out the extra cash, it does provide excellent sound quality, even with the top down. The infotainment system features a crisp, responsive screen and easy-to-navigate menus. Alternatively, you can use voice controls if you don't want to fiddle with the iDrive controller. The system is quite accurate, but because it is cloud-based, it can be slow to respond. All of the 8 Series' advanced driving aids work well.
Storage
7/10
How’s the storage? It can be tough to criticize the trunk space in a convertible, but the 840i is neither small nor inexpensive. As such, we expected a bit more efficient use of space. With the top up, the trunk has a decent capacity of 12.4 cubic feet. That puts it well ahead of the 911 Cabriolet and the Lexus LC 500 convertible.
But all that capacity vanishes if you'd like to put the top down as you need to deploy a trunk divider, which essentially leaves space for two half-full grocery bags. The rear seats do fold for longer items — assuming the top is up — but the opening is quite narrow.
It's much better on the inside, where both front passengers will find ample room for their personal items, especially in the long, padded door pockets. The rear seats do have anchors for car seats, but they're better used for holding bags and jackets.

Fuel Economy
7.5/10
How’s the fuel economy? The 840i convertible gets an EPA fuel economy estimate of 24 mpg combined (21 city/29 highway), which is a bit higher than most rivals. Our test car got 23.4 mpg on our highway-heavy 115-mile evaluation route. That's a bit disappointing considering the bias toward highway driving on our route.
Value
8/10
Is the 8 Series a good value? You're bound to have high expectations when you're shopping for a six-figure convertible, and the 840i delivers. It has premium build quality, along with excellent interior materials. We would avoid the optional glass controls and a few other packages, though, to keep the cost down.
BMW's four-year/50,000-mile basic warranty is average for the class. Three years of free maintenance is a bit less common, however, and it helps the 8 Series' score here.
Wildcard
8/10
At its heart, the 8 Series convertible is a road-trip kind of vehicle. It's quiet as a mouse on the highway and comfortable over any surface. And when the roads get twisty, you can still have quite a bit of fun behind the wheel. This convertible also has plenty of get-up-and-go. Looks are subjective, but the 8 Series feels pretty stately whether you're staring at it in a parking spot or cruising down the coast.
Which 8 Series does Edmunds recommend?
It isn't the fastest or most expensive version of the 8 Series, but we recommend the 840i coupe. Quick enough in a straight line, available with rear-wheel or all-wheel drive, and equipped with a rakish fixed roof that preserves trunk space, this version of the car offers flexibility and choice. And with the money you'll save over a higher trim, you can upgrade it with extra features.
The Edmunds experts tested the 2025 8 Series both on the road and at the track, giving it a 7.9 out of 10. What about cargo capacity? When you're thinking about carrying stuff in your new car, keep in mind that carrying capacity for the 8 Series ranges from 12.4 to 14.8 cubic feet of trunk space. And then there's safety and reliability.
