2023 BMW 8-Series Review, Pricing, and Specs

Overview

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.

What’s New for 2023?

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.

Pricing and Which One to Buy

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.

Engine, Transmission, and Performance

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.

Fuel Economy and Real-World MPG

The more powerful M850i, which includes a twin-turbo V-8 and standard all-wheel drive, means a significant reduction in EPA fuel-economy ratings versus the turbo six-cylinder that powers 840i models. The M850i is rated up to 17 mpg city and 25 highway, whereas the less powerful 840i has estimates of up to 23 mpg city and 30 highway. We tested the M850i coupe and convertible on our 75-mph fuel-economy route where they achieved 29 and 26 mpg, respectively. While both body styles exceeded their EPA ratings, the coupe did so by 4 mpg whereas the soft top only managed 1 mpg more. For more information about the 8-series’ fuel economy, visit the EPA’s website.

Interior, Comfort, and Cargo

The 2023 8-series interior offers all the infotainment gadgetry and luxury features expected in a high-priced grand tourer. Every model has 14-way power-adjustable heated front seats, soft-close automatic doors, and customizable ambient lighting; more extravagant upgrades include glass control and additional high-end materials. It can even be outfitted with unique BMW Individual options, such as a fancy white-and-brown color scheme. Although it does offer a pair of vestigial rear seats, they’re not pleasant places for adults to spend time. The 8’s low roofline also impedes headroom in the front seat and outward visibility isn’t great, but that’s the price of fashion. Its interior cubby storage consists of a coverable tray at the front of the center console, a useful central bin, and adequate door pockets. We also managed to fit five carry-on bags in the coupe’s trunk and another six with the back seats stowed, but the convertible held one bag less in each scenario.

Infotainment and Connectivity

A 12.3-inch digital gauge cluster and a 12.3-inch touchscreen are standard on every 8-series. Unfortunately, the instrument panel is overcrowded and not particularly intuitive to operate with the steering-wheel controls. The infotainment system has a variety of ways to interact with it, including a useful rotary knob on the center console. It also features standard Apple CarPlay capability, wireless charging, and a Wi-Fi hotspot—Android Auto is absent. Those who want a more elaborate sound system can opt for the Bowers & Wilkins Diamond surround system.

Safety and Driver-Assistance Features

The 2023 8-series offers myriad driver-assistance technology, including a semi-autonomous driving mode. For more information about the 8-series’ crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard forward-collision warning and automated emergency braking
• Available adaptive cruise control with stop-and-go technology
• Available lane-departure warning and lane-keeping assist

Warranty and Maintenance Coverage

BMW covers every 2023 8-series with a competitive limited warranty, however, it flip-flops advantages with its Lexus rival. While the LC has an extra two years or 20,000 miles of powertrain protection, the 8 lineup includes an additional two years or 26,000 miles of complimentary scheduled maintenance.

• Limited warranty covers four years or 50,000 miles
• Powertrain warranty covers four years or 50,000 miles
• Complimentary maintenance is covered for three years or 36,000 miles
