BMW M850i XDrive Gran Coupe 2020: 523-HP Grand Tourer Review

The 2020 BMW M850i xDrive Gran Coupe stands out as a versatile powerhouse, merging the sleek aesthetics of a coupe with the functionality of a four-door sedan. Powered by a twin-turbo 4.4-liter V8 engine producing 523 horsepower and 553 lb-ft of torque, this vehicle accelerates from 0-60 mph in under 4 seconds, thanks to its xDrive all-wheel-drive system and eight-speed automatic transmission. Weighing around 4,400-4,700 pounds depending on options, it delivers shocking straight-line speed while maintaining composure on long highway cruises or twisty roads.

Striking Exterior Design and Aerodynamics

BMW’s design team crafted the M850i Gran Coupe with an elongated silhouette that enhances its visual appeal. The body stretches 231mm longer than the standard 8 Series Coupe, primarily due to a longer wheelbase, which improves stability without sacrificing agility. Wide hips from an expanded rear track give it the broadest stance in BMW’s lineup, contributing to a planted, muscular look.

Laser headlights illuminate the path with precision, paired with slim LED taillights and a relatively modest kidney grille compared to later models. The low-slung roofline evokes a coupe-like profile, but practical doors ensure easy access for rear passengers. Carbon-fiber trim options accentuate its sporty character, while 20- or 21-inch wheels fill the arches aggressively. This design not only turns heads but also aids aerodynamics for efficient high-speed travel.

Luxurious Cabin Packed with Technology

Inside, the cabin rivals premium sedans with high-quality leather seats, multi-zone climate control, and an intuitive iDrive infotainment system featuring a 10.25-inch central screen. Wireless Apple CarPlay is standard, though Android Auto requires checking specific markets. Gesture controls and a panoramic glass roof enhance the futuristic feel.

Front seats offer heating, ventilation, and ample support for long drives, with optional crystal controls adding a sparkling touch for $1,730. Rear space accommodates four adults comfortably, though the sloping roofline limits headroom for taller passengers—better suited for two rather than three in the back. A Bowers & Wilkins 16-speaker audio system elevates the experience, and driver aids like adaptive cruise control and parking cameras come standard.

While not matching the Mercedes S-Class in opulence, the materials and build quality impress, with a quiet cabin isolated from road noise in Comfort mode.

Explosive V8 Performance and Drivetrain

At the heart lies BMW’s S63 4.4-liter twin-turbo V8, tuned for M Performance with 523 hp. Paired with xDrive AWD and a ZF eight-speed automatic, it propels the car to 0-100 km/h (62 mph) in 3.9-4.2 seconds. Reviewers note its smoothness, with instantaneous throttle response and rapid shifts, making overtakes effortless.

• Peak Power: 523 hp @ 5,500 rpm
• Torque: 553 lb-ft @ 1,800-4,500 rpm
• Transmission: 8-speed automatic with paddle shifters
• Drive: xDrive AWD with rear bias

Top speed is electronically limited to 155 mph, but the real thrill is the surge from low revs, mimicking a rocket launch. Fuel economy hovers around 17-20 mpg combined, respectable for its power.

Dynamic Handling and Ride Quality

Despite its 4,683-pound test weight, the M850i feels nimble thanks to rear-wheel steering, sharp steering, and adaptive M-tuned dampers. In Adaptive mode, it adjusts throttle, suspension, and shifts to the road, offering fluid body control over undulations while firming up for corners.

Sport and Sport+ modes sharpen responses, increase steering effort, and amplify exhaust notes—though some find the artificial engine sound intrusive. It pulls 0.95 g on skidpads in lighter variants, with impressive braking from 70-0 mph in 152 feet. Urban potholes challenge the stiff run-flat tires, but overall ride comfort rivals luxury sedans.

Practicality for Daily and Long-Distance Use

This gran coupe shines as a daily driver and tourer. Trunk space swallows luggage for four, and the longer wheelbase smooths highways better than the coupe. Rear seats fold for versatility, and it’s family-friendly for non-tall occupants. City maneuvering benefits from cameras and sensors, though low clearance demands care.

Compared to rivals:

Test cars often exceeded $120,000 with options, positioning it against premium competitors.

Technology and Safety Features

Advanced driver aids include lane-keeping, blind-spot monitoring, and night vision in packages. The heads-up display and digital gauges keep focus on the road. xDrive enhances traction in snow, as noted in winter tests. Reliability aligns with BMW standards, with the powertrain proven in X5/X6 M50i.

Pros and Cons at a Glance

• Pros: Blistering acceleration, stunning looks, comfortable ride, tech-rich interior, AWD grip
• Cons: Rear headroom tight, artificial engine sound, pricey options, less agile than true sports sedans
