Powertrain & Engine Architecture
At the heart of the 840i Gran Coupe LCI lies the BMW B58B30C 3.0-liter inline-six engine. This engine is a cornerstone of BMW’s modern powertrain strategy, known for its smooth power delivery and efficiency. The ‘B58’ designation indicates its position within BMW’s modular engine family. It utilizes direct fuel injection, a twin-scroll turbocharger, and Double-VANOS variable valve timing for both intake and exhaust. The engine produces 333 horsepower at 5500-6250 rpm and 500 Nm (368.78 lb-ft) of torque between 1700 and 4000 rpm. This broad torque curve contributes to strong acceleration in real-world driving conditions. The engine is paired with an 8-speed Steptronic automatic transmission, which offers smooth and quick shifts. This transmission is programmed for both comfort and performance, with the ability to manually shift using steering wheel-mounted paddles.
Driving Characteristics
The 840i Gran Coupe LCI delivers a refined and engaging driving experience. The combination of the 3.0-liter inline-six and the 8-speed automatic results in a 0-60 mph time of approximately 5.1 seconds. While not as overtly sporty as the M8 Competition, the 840i offers ample power for confident overtaking and highway cruising. The automatic transmission is well-tuned, providing seamless gear changes and contributing to a relaxed driving experience. The suspension, tuned for comfort, effectively absorbs road imperfections, while still providing a sense of control in corners. Compared to the 830d, the 840i offers significantly more power and a more responsive feel. It lacks the ultimate performance of the M8 Competition, but provides a more balanced and accessible driving experience for many drivers.
Equipment & Trim Levels
The 840i Gran Coupe LCI comes standard with a comprehensive suite of features, reflecting its positioning as a luxury vehicle. Standard equipment includes BMW’s Live Cockpit Professional, featuring a 12.3-inch digital instrument cluster and a 10.25-inch central touchscreen display. Leather upholstery, ambient lighting, and a premium sound system are also standard. Optional extras include upgraded leather options, a Bowers & Wilkins Diamond Surround Sound System, active integral steering, and various driver-assistance systems such as adaptive cruise control and lane keeping assist. The LCI facelift brought updated interior trim options and enhanced connectivity features.
Chassis & Braking
The 840i Gran Coupe LCI utilizes a sophisticated chassis design. It features a double-wishbone front suspension and an independent multi-link rear suspension, optimized for both comfort and handling. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Electronic stability control (ESC) and anti-lock braking system (ABS) are standard safety features. The steering system is an electric power steering setup, offering precise and responsive control. The car’s weight distribution is carefully balanced to enhance handling characteristics.

Critics note that the 840i strikes a good balance between performance and comfort, making it a versatile grand tourer. Compared to competitors such as the Mercedes-Benz CLS and Audi A7, the 840i is often lauded for its engaging driving dynamics and sophisticated technology. Fuel economy is respectable for a vehicle of this size and performance, with combined fuel consumption ranging from 8.4 to 8.9 l/100 km. Reliability has been generally good, although some owners have reported minor issues with the infotainment system.
Legacy
