Overview
BMW may no longer represent the pinnacle of driver engagement, but its 2020 8-series shows it can build a top-notch grand tourer. Available as a coupe or convertible, the big two-door Bimmer rides with a smoothness and quietness that befits its prodigious price tag. A pair of refined and responsive powertrains help expedite its passengers to their destination, and its well-sorted chassis provides enough agility to enthrall the driver. Although its sloping roofline hinders the view out back, the interior is an expertly crafted space that can be filled with the finest features and materials. The 2020 BMW 8-series won't stun onlookers with its styling, but its presence undoubtedly commands respect.
What's New for 2020?
For 2020, BMW introduces the less expensive and less powerful 840i models. Available with rear- or all-wheel drive—and as a coupe or convertible—these versions use a twin-turbo inline-six that makes 335 horsepower and 368 lb-ft of torque and hooks up to an eight-speed automatic transmission. BMW also adds the handsomer 8-series Gran Coupe to the lineup, but we review that body style separately.
Pricing and Which One to Buy
It's hard to find the comparatively subdued 2020 8-series more desirable than the absolutely gorgeous 2020 Lexus LC. However, that changes once you're behind the wheel, especially with the M850i's delightfully powerful twin-turbo V-8. As such, we'd recommend that model in convertible form. While it costs an extra $10,000, that money is well spent when its dropped top opens up the otherwise confined-feeling cabin. In order to avoid matching the lofty price tag of the BMW M8, which we review separately, we'd be smart with our selected options. That means we'd only add the glass controls, neck warmer, and both driver-assistance packages that altogether cost a reasonable $3350.
Engine, Transmission, and Performance
BMW's biggest coupe and convertible start off with a 335-hp twin-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 important, 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 18 mpg city and 25 highway, whereas the less powerful 8 has estimates of up to 23 mpg city and 30 highway. We tested the M850i coupe and convertible on our 200-mile 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 softtop only managed 1 mpg more.
Interior, Comfort, and Cargo
The 2020 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 10.3-inch touchscreen are standard on every 2020 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 2020 8-series hasn't been crash-tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). It does offer myriad driver-assistance technology, including a semi-autonomous driving mode. 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 2020 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 4 years or 50,000 miles
- Powertrain warranty covers 4 years or 50,000 miles
- Complimentary scheduled maintenance is covered for 3 years or 36,000 miles
