Composed of elegantly styled coupe and convertible models, the 2023 BMW 8-series lineup mixes grand proportions with luxurious appointments. While they’re not as visually dramatic or practical as the four-door 8-series Gran Coupe version (reviewed separately), both of the two-door body styles are terrific boulevard cruisers. Thanks to a pair of smooth engine options—particularly the gutsy 523-hp twin-turbo V-8—the 8 coupe and convertible have the giddy-up to match their opulence. If extreme performance is a priority, the separately reviewed M8 models fit the bill. Apart from poor outward visibility and a snug back seat, the inside of the 2023 8-series is beautiful and supremely quiet. The Lexus LC will attract more attention, but the Bimmers offer a better ride-and-handling balance and an unquestionably upscale experience.

BMW gives the 2023 8-series coupe and convertible a handful of small updates, including a subtlety revised front fascia with a newly standard illuminated kidney grille. Both body styles can now be had with new wheel designs and fresh metallic paint colors: Skyscraper Grey, San Remo Green, Portimao Blue, Frozen Tanzanite Blue, and Frozen Pure Grey. The M850i adds aerodynamic side mirrors—courtesy of the M8 models—and an M badge in the grille. The newly optional M Sport Package Professional (coupe only) brings dark elements to the grille and headlights as well as black-painted brake calipers; on the M850i it adds a black spoiler, too. To commemorate the 50th anniversary of BMW’s M performance division, the M850i can now be had with the classic M logo, which replaces the exterior BMW roundel badges. Inside, the touchscreen grows from 10.3 to 12.3 inches.

We prefer the prodigious power of the all-wheel-drive-only M850i, with its 523-hp twin-turbo V-8. We also like the type of drama provided by the regal and more immersive drop-top version, even if it comes with a nearly $10k surcharge. The 8’s cabin is lavishly appointed with leather covering most every surface and attractive accents, both of which can be mixed to match everyone’s preferred aesthetic. We’re particularly fond of the Cognac Merino leather and Aluminum Dark Trace interior trim. Among the options we’d select are the glass controls for an even ritzier interior, and the neck warmers in the front-seat headrests­ that’ll allow us to enjoy longer periods of top-down driving in our four-season state.

BMW’s biggest coupe and convertible start off with a 335-hp turbocharged inline-six-cylinder. These 840i models pair with an eight-speed automatic transmission and either rear- or all-wheel drive (called xDrive in BMW’s parlance). While we haven’t driven an 8 with the six-cylinder, BMW has built a reputation on silky smooth and responsive powertrains, so only speed freaks will likely be disappointed. Instead, we’ve driven both body styles of the M850i that feature a 523-hp twin-turbo V-8, eight-speed automatic, and standard all-wheel drive. This combination delivers impressive acceleration for the Bimmer’s size and provides a rich soundtrack in the sportiest setting. Likewise, the transmission transitions from relaxed to reactive based on the driver’s right foot. Most importantly, the 8-series delivers on its grand-touring promises, with a supremely quiet ride and surprising athleticism. Its steering feedback is direct and linear but filters out road imperfections and front-tire feedback. Although its adaptive dampers allow extra flexibility depending on the selected drive mode, they make the 8 remarkably stable during cornering in their stiffest setting. The car’s powerful brake system and firm pedal feel further enhance the feeling of absolute confidence.
