The 8 Series was one of a kind performance car back in the 90s when it was first introduced. It went away when the sales drastically dropped. It took BMW 18 years to bring back the 8 Series to the market. The second-generation BMW 8 Series is a recent addition to the lineup of its high-performance luxury cars. The 8 Series is available in Coupe, Convertible, and Gran Coupe body styles, and this lineup replaced the 6 Series.

All the cars are powered by V8 engines, except the Porsche 911, which shines with its same old 6-cylinder engine. The AMG S 63 is the fastest with its 0-60 MPH performance, while the 911 tails behind it by leaving the M850i in the third spot. The 911 Carrera S does the fastest quarter-mile where it takes down both BMW M850i and the Mercedes AMG S 63 by a small margin. The BMW M850i (without rev limiter) sits atop the list with its 191 MPH speed alongside the 911 Carrera S.

How well does the 2021 BMW M850i Coupe handle?

With its Adaptive M suspension, the thrill of driving a BMW is enhanced by both sophistication and comfort. The damper control works well on the M850i where the active roll stabilization provides balance to the car at high speeds. The M Sport differential delivers power to all four wheels with the xDrive AWD system.

The multi-link aluminum suspension both at the front and the back further enhances the ride quality and comfort. With a Servotronic power-assist steering wheel, the M850i handles well. The integral rear axle steering provides better agility and maneuverability with a short turning radius and agile handling dynamics.

Braking Performance

The BMW M850i is equipped with a 4-wheel ventilated disc M Sport brake setup from Brembo with composite front rotors, dynamic brake control, and cornering brake control. The front wheels have 15.5-inch brake rotors with four-piston calipers, whereas the rear gets 15.5-inch brake rotors with a single-piston caliper. With its 4,478 pounds of weight, the M850i has impressive braking performance and minimal brake fade.

The BMW M850i takes just 105 feet of distance to stop from 60 MPH of speed. With its huge 15.5 inch brakes both at the front and the rear, it takes down both Mercedes AMG S 63 and the Lexus LC 500. The lightweight Porsche 911 Carrera S is still ahead with its 100 feet stopping distance from 60 MPH despite having the smallest rotors of the lot at both ends.

2021 BMW M850i Fuel Economy

8.0/10

Other than delivering an astonishing performance, the M850i is capable of taking you places with its satisfactory fuel economy. With its 523 hp engine, it delivers 17 mpg in the city, 25 mpg on the highway, and 20 mpg combined. It has an 18.0-gallon fuel tank that pushes the range up to 306 miles, 450 miles, and 360 miles in the city, on the highway, and in combined driving conditions, respectively. Overall, the numbers are amazing for such a performance car.

Other than the Porsche 911, the BMW M850i also offers great city mileage. In terms of highway range, the AMG S 63 is slightly better than the other cars. However, when it comes to combined mileage, the M850i matches the 911 Carrera. As the rivals offer bigger fuel tanks, both Lexus and Mercedes manage to offer a combined range of more than 400 miles.

2021 BMW M850i Interior

9.0/10

Since its launch in 2018, the cabin of the BMW M850i has remained mostly unchanged. Still, we received certain technology and convenience upgrades over time. For 2021, the cabin is wrapped in premium Merino leather upholstery with ash grain wood trims and metal-look accents. The driver-oriented dashboard is configured with multiple displays and glass controls on the center console. You can even wrap the dashboard in Nappa leather upholstery. The M Sport leather steering wheel gives you a clear view of the driver's display, while the optional heads-up display can be controlled with the steering-mounted buttons.

2021 BMW M850i Coupe cockpit area

The M850i seats 4 passengers in its lavish cabin. For the front, BMW offers 18-way power-adjustable heated bucket seats with cushion extension, side bolsters support, articulating upper backrest, and 4-way lumbar support. The easy-entry front seats make way for the rear 50-50 split bucket seats, which are unfortunately a bit too upright.

Other than that, we have a Live Cockpit Pro instrument cluster with satellite navigation, check control vehicle monitor, wireless charging, dual-zone automatic air-conditioning, auto tilt-away steering, dynamic cruise control, day-night auto-dimming rear-view mirror, cell phone pre-wiring, and a rearview camera.

The 2021 BMW M850i Coupe is just like other sports coupes in terms of seating and space. However, it is no match to the Mercedes AMG S 63 when it comes to cabin space. Still, you have decent shoulder room and legroom in the front row. The second row is cramped as compared to the one of the AMG S 63. Even the Lexus LC 500 offers competitive cabin space. BMW has focused on practicality as it offers the best in class trunk capacity of 14.8 cubic feet. Some of the highlights of the interior features are:

  • Merino leather upholstery
  • 18-way power ventilated seats
  • Nappa leather dashboard
  • Ash grain wood trims
  • M Sport leather steering wheel
  • Live Cockpit Professional
  • Dynamic cruise control

What's there to keep you entertained?

The M850i has a 10.2-inch iDrive 7.0 infotainment screen that sits at the center of the dash. The infotainment is operated via voice, touchscreen, and a touchpad controller placed on the center console. For device connectivity, it has Apple CarPlay and Android Auto as standard. With that, you have enhanced USB and Bluetooth connectivity as well. The SiriusXM 360L Radio is a new addition to the package with a complete 1-year subscription. With BMW Connected Services, you get access to a WiFi hotspot with 3 GB trial data for 3-months.

The audio streaming livens up the cabin with the Harman-Kardon surround-sound audio system with 16 speakers and a 464W amplifier. The BMW Live Cockpit Professional comes with a 12.3-inch driver's display. The display optimizes the driver information for clarity and visibility. With that, you have a satellite navigation system that comes with over-the-air map data updates. The heads-up display projects vehicle's info below the driver's line of vision on the windshield. Some of the highlights of the infotainment system are: 

  • iDrive 7.0 with 10.2-inch multi-input display
  • Touchpad controller
  • Apple CarPlay
  • Android Auto
  • Bluetooth and USB tethering

2021 BMW M850i Exterior

9.0/10

The 2021 BMW M850i Coupe stands out when compared with the regular BMW sedans and coupes. With its aggressive looks and sloping roofline, the 8 Series is one of a kind. Within a short period, the 8 Series has taken over as the most stylish BMW coupe in the lineup. The customization options and the M Sport package gives it a more detailed styling. The sharp LED laser headlamps shine bright even during the day with the LED DRLs. The widened chrome grille is paired with an aerodynamic bumper with huge air intakes. The design lines from the hood climb up the roof and slope down the rear. The aerodynamic door lines make way for the air from the side panels.

2021 BMW M850i Coupe 

The M850i has a hefty tail as seen from the rear. To make it look better, it has a set of sleek LED tail lamps and massive aerodynamic bumpers, and a roaring sports exhaust with quad tails. As standard, the M850i rides on 20-inch M V-spoke cerium grey wheels with blue piston calipers. You can avail yourself of the jet black wheels with high-performance tires and matt black calipers. The exterior of the M850i can be configured with chrome accents, carbon fiber inlays, and an optional aerodynamic kit. You have 11 premium metallic color options to choose from, out of which the Dravit Grey metallic arguably looks the best. The extended shadow line trim further darkens the tone of the paint job.

BMW has perfectly designed the M850i to sit between its high-end Sedans and Gran Coupes to deliver a luxury sports car experience. In terms of weight, it is more than a hundred pounds lighter than the AMG S63 and a few inches shorter in terms of length. Still, the M850i looks quite raw with its wide body and a sports car stance. With a 5.0-inch ground clearance, it rides higher than other cars in its segment except for the Lexus LC 500 which is higher. The short wheelbase is the reason behind its agility. Some of the highlights of the exterior features are:

  • LED laser headlamps with DRLs
  • Chrome grille
  • Aerodynamic bumpers
  • Quad tail sports exhaust
  • Carbon fiber exterior package
  • Metallic paint options
  • 20-inch V spoke jet black wheels

2021 BMW M850i Safety

9.9/10

The 2021 BMW M850i Coupe gets its strength from the BMW CLAR platform. BMW has made good use of carbon fiber in its chassis and the remaining structure to make it more balanced, rigid, and structurally advanced in terms of safety. Being a high-performance luxury coupe, the BMW M850i has not been crash-tested by the IIHS or the NHTSA.

BMW is known for its advanced safety that protects its passengers on the road. The BMW Active Guard comes with a frontal collision warning and city collision mitigation with braking. Now the lane departure warning is offered as standard as well. On top of that, you have dynamic cruise control, an active protection system, and a driver attention alert. Some of the standout safety features are: 

  • BMW CLAR platform
  • Frontal collision warning
  • City collision mitigation with braking
  • Lane departure warning
  • Dynamic cruise control
  • Driver attention alert

2021 BMW M850i Coupe vs 2021 Mercedes AMG S 63 Coupe

The BMW M850i offers a valuable package with its amazing exterior styling, a power-packed V8 engine, onboard technology, and driver's convenience and assistance options. Moreover, the M850i both rides and handles well with its M sport-tuned steering and suspension. On the other hand, the Mercedes-Benz AMG S 63 is up a notch with its remarkable power and price bump as compared to the M850i. It's in no way less desirable than the BMW in any aspect. Moreover, the AMG S63 has better comfort and overall luxury. Still, the M850i seems like a value-for-money package.

2021 BMW M850i Coupe vs 2021 Porsche 911 Carrera S Coupe

The BMW M850i has to climb up the ladder to stand beside the iconic Porsche 911 Carrera S. Even after several years, the 911 remains unbeatable with its dynamic driving, lightweight construction, and an engine that spares no one. The M850i coupe is well packed to deliver close enough performance with better luxury, convenience, and an affordable price tag. However, the 911 Carrera is on another level as it can still take down the M850i in one go. With a bit of practicality, the BMW M850i gets ahead of the Porsche 911 in day-to-day liveability.

2021 BMW M850i Coupe vs 2021 Lexus LC 500 Coupe

The Lexus LC 500 sounds like the best coupe you can avail at such a price. When you dig deep into the performance figures and options, nothing is surprising about the LC 500 as it's not that special. For some extra cash, you can avail yourself of the BMW M850i with better power, ride quality, and impressive performance. The M850i even delivers better fuel economy than the LC 500 with its 523 hp V8. Also, the LC 500 has an RWD drivetrain, which can be fun, but the M850i is more capable with its standard AWD system. Moreover, the cabin space of the BMW is more practical as well.

2021 BMW M850i Final Verdict

9.1/10

BMW has finally revived its 8 Series in the best way possible. The M850i is made to rule the streets with its performance and handling. Another thing that BMW did right is the design and has made the 8 Series more sensible by avoiding the polarizing design language of the recent sedans. From the inside, BMW has equipped it with the latest driver assistance features, convenience options, and entertainment features to keep the driver satisfied. BMW also offers optional packages to further equip your M850i. With that, the 2021 BMW M850i Coupe is a worthy choice in the segment. It holds its own against the fierce rivals at a much lower cost. We can expect the M850i to get even better with upgrades down the line.
