2023 BMW M850i XDrive: 523-HP Grand Tourer Tested

The 2023 BMW M850i xDrive stands out as a high-performance luxury coupe that combines a potent twin-turbo V8 engine with sophisticated all-wheel-drive dynamics, offering drivers an engaging yet comfortable experience on long journeys and spirited drives alike.

Powertrain and Acceleration Excellence

At the core of the M850i xDrive lies a 4.4-liter twin-turbocharged V8 engine producing 523 horsepower and 553 lb-ft of torque, available from as low as 1,800 rpm, paired with an 8-speed automatic transmission and xDrive all-wheel drive. This setup propels the coupe from 0-60 mph in just 3.7 seconds, rivaling more focused sports cars while maintaining grand touring poise.

The engine’s delivery is seamless, with low-end torque providing effortless overtaking power on highways and a throaty snarl in Sport mode that transforms the car into a predator on open roads. Reviewers note the V8’s characterful exhaust note drowns out any turbo lag concerns, making every throttle application rewarding. The transmission shifts reactively, holding gears longer in performance modes to maximize engagement.

• Peak Power: 523 hp @ 5,500 rpm
• Torque: 553 lb-ft @ 1,800-4,500 rpm
• 0-60 mph: 3.7 seconds
• Top Speed: Electronically limited to 155 mph (higher with optional packages)

Chassis Dynamics and Handling Balance

Despite its nearly 4,700-pound curb weight, the M850i xDrive handles with surprising composure thanks to adaptive dampers, rear-biased xDrive, and optional rear-wheel steering. The suspension soaks up road imperfections in Comfort mode, transitioning to firmer settings in Sport without becoming harsh, outperforming rivals like the Porsche 911 Turbo S in ride compliance.

Cornering reveals a rear-drive bias that encourages playful rotation, though the steering lacks the sharp feedback of lighter BMW M cars due to the four-wheel steering system designed for stability in larger vehicles. Braking is confident with massive rotors halting the car from high speeds without drama. Overall, it’s a cruiser that complies enjoyably on twisty roads but shines on high-speed sweeps.

Luxury Interior and Technology Features

The cabin exudes premium quality with high-definition 12.3-inch touchscreen, supple leather upholstery, and programmable shortcut buttons alongside a rotary iDrive controller. Materials feel top-shelf, though lumbar support could be enhanced, and the interface shows its age compared to newer BMWs like the i4.

Seating is supportive for long hauls, with sculpted fronts offering thick padding that hugs without fatigue. Rear space is adequate for adults on shorter trips, but blind spots from thick pillars remain a noted drawback. Ambient lighting and a digital gauge cluster elevate the ambiance, creating a decadent environment.

• Head-up display standard
• Mark Levinson or Bowers & Wilkins audio options

Fuel Efficiency and Practicality

Expect 17 mpg city and 24-25 mpg highway per EPA ratings, with real-world tests achieving up to 29 mpg on highway loops for the coupe. The 21-gallon tank supports reasonable range for touring, though the V8’s thirst is evident in aggressive driving. Trunk space accommodates golf bags or weekend luggage, enhancing GT credentials.

Design and Styling Appeal

The M850i’s slinky silhouette turns heads with aerodynamic mirrors, M badges, and optional dark accents from the M Sport Professional package. It’s understated luxury rather than overt aggression, blending seamlessly into premium environments while hinting at its performance.

Safety and Driver Assistance

Standard features include forward collision warning, automatic emergency braking, lane departure warning, and adaptive cruise control. The xDrive system enhances stability in wet conditions, and large brakes provide reassurance.

Pricing and Value Proposition

Starting around $100,000 for the coupe, the M850i offers strong value against Bentley Continental GT rivals, with depreciation to about $54,100 after three years. It’s a V8 holdout in an electrifying world, prioritizing character over ultimate efficiency.
