The BMW 840i xDrive Gran Coupe, launched in 2020, is a four-door coupe that blends the sporting character of the 8 Series with increased practicality. Positioned within the G16 generation, it offered a more accessible entry point into the 8 Series range compared to the higher-performance M8 and M8 Competition models. The “Gran Coupe” designation signifies the four-door body style, differentiating it from the two-door 8 Series Coupe and Convertible. This model aimed to appeal to buyers seeking a luxurious, high-performance vehicle capable of comfortably accommodating passengers and luggage.

Powertrain & Engine Architecture

At the heart of the 840i xDrive Gran Coupe lies BMW’s B58B30C 3.0-liter inline-six engine. This engine is a cornerstone of BMW’s modern powertrain lineup, known for its smooth power delivery and efficiency. The B58 utilizes direct fuel injection, a twin-scroll turbocharger, and BMW’s VALVETRONIC variable valve timing and lift system. VALVETRONIC allows for precise control of valve timing and lift, optimizing engine performance and fuel economy across a wide range of driving conditions. The engine produces 333 horsepower at 5500-6250 rpm and 500 Nm (368.78 lb-ft) of torque between 1700 and 4000 rpm. This power is then channeled through an eight-speed Steptronic automatic transmission, which features smooth and quick shifts. The xDrive all-wheel-drive system intelligently distributes power between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.

Driving Characteristics

The 840i xDrive Gran Coupe delivers a refined and engaging driving experience. While not as overtly aggressive as the M8, the 3.0-liter inline-six provides ample power for confident acceleration and effortless highway cruising. The eight-speed automatic transmission is well-tuned, offering seamless gear changes and contributing to the car’s overall smoothness. The xDrive system provides a secure and planted feel, inspiring confidence in various driving conditions. Compared to a manual transmission equipped 8 Series, the automatic prioritizes ease of use and comfort. While a manual might offer a more direct connection for driving enthusiasts, the Steptronic transmission’s responsiveness and efficiency make it well-suited to the 840i’s grand touring character. The 0-60 mph time of around 4.8 seconds is respectable, placing it firmly in the performance coupe category.

Equipment & Trim Levels

The 840i xDrive Gran Coupe came generously equipped as standard. Typical features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, a large infotainment display with iDrive controller, and a comprehensive suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Optional extras included upgraded leather options, a Bowers & Wilkins Diamond Surround Sound System, active roll stabilization, and a head-up display. Interior trim options ranged from elegant wood veneers to modern carbon fiber accents. The dashboard layout is driver-focused, with a clean and intuitive design.

Chassis & Braking

The 8 Series Gran Coupe features a sophisticated chassis designed to balance comfort and handling. The front suspension utilizes a double wishbone setup, while the rear employs an independent multi-link suspension. This configuration provides excellent wheel control and a comfortable ride. The 840i is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The braking system is further enhanced by ABS, dynamic stability control, and corner brake control. The car’s weight distribution is carefully optimized to enhance handling balance.

Market Reception & Comparison

The 840i xDrive Gran Coupe was generally well-received by automotive critics. Reviewers praised its luxurious interior, refined driving experience, and powerful engine. The xDrive all-wheel-drive system was also highlighted as a significant benefit, particularly in regions with inclement weather. Compared to the 840i Coupe, the Gran Coupe offered increased practicality thanks to its four doors and larger rear seating area. Fuel economy was considered reasonable for a vehicle of its size and performance, averaging around 30 mpg combined. Reliability reports have been generally positive, with the B58 engine proving to be a robust and dependable unit.

Legacy

The BMW 840i xDrive Gran Coupe (G16) represents a modern interpretation of the classic grand touring formula. The B58 engine has established itself as a highly regarded powerplant, known for its performance and longevity. On the used car market, these models hold their value relatively well, reflecting their desirable combination of luxury, performance, and technology. The G16 8 Series, including the 840i, has cemented BMW’s reputation for building sophisticated and engaging automobiles.
