The BMW M6 (E63 LCI), specifically the facelifted version produced from 2007 to 2010, represents the pinnacle of the E63 generation. Powered by the S85B50A 5.0-liter V10 engine producing 507 horsepower, and paired with a 7-speed Sequential Manual Gearbox (SMG), this variant aimed to deliver uncompromising performance and a uniquely engaging driving experience. The LCI (Life Cycle Impulse) facelift brought subtle styling revisions, improved interior refinements, and refinements to the SMG transmission, addressing some criticisms leveled at the pre-facelift models. Positioned as the high-performance coupe derivative of the 6-Series, the M6 competed with grand tourers like the Porsche 911 and Aston Martin DB9, offering a blend of luxury, technology, and track-capable performance.

INTRODUCTION
The BMW M6 (E63 LCI) represents the culmination of BMW’s engineering prowess in the early 2000s. Introduced as a facelift to the original E63 M6 in 2007, it built upon the foundation of the 6-Series coupe, transforming it into a high-performance machine. The LCI updates included revised styling cues, such as redesigned headlights and taillights, as well as interior enhancements. However, the heart of the M6 remained its remarkable 5.0-liter V10 engine. This engine, derived from BMW’s Formula 1 program, delivered an exhilarating driving experience characterized by its high-revving nature and potent power output. The SMG transmission, while controversial, offered rapid gear changes and a direct connection to the engine.
Powertrain & Engine Architecture
The S85B50A engine is a naturally aspirated 5.0-liter (4999 cc) V10. It features an aluminum alloy block and cylinder heads, and utilizes Double-VANOS (variable valve timing) on both intake and exhaust camshafts. The engine employs individual throttle bodies for each cylinder, contributing to its sharp throttle response. Fuel is delivered via a multi-port fuel injection system. The engine’s high compression ratio of 12:1 necessitates premium fuel. The 7-speed SMG (Sequential Manual Gearbox) is a single-clutch automated manual transmission. It allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles. The SMG’s programming was refined in the LCI models to improve shift smoothness and reduce jerkiness compared to earlier versions.
Driving Characteristics
The M6 LCI delivers a driving experience that is both exhilarating and demanding. The 507 horsepower and 383 lb-ft of torque provide ample power for rapid acceleration. The 0-60 mph sprint takes approximately 4.4 seconds, and the car is electronically limited to a top speed of 155 mph. The SMG transmission, when driven aggressively, offers incredibly fast gear changes, but can feel less refined during low-speed maneuvers. The suspension is firm, providing excellent body control, but can be unforgiving on rough roads. The steering is precise and communicative, offering a direct connection to the road. Compared to the standard 6-Series, the M6’s driving experience is significantly more focused and performance-oriented.
Equipment & Trim Levels
The M6 LCI came standard with a comprehensive list of features, including leather upholstery, power-adjustable heated seats, a premium sound system, and automatic climate control. Optional extras included carbon fiber interior trim, upgraded leather options, a head-up display, and active suspension. The M6’s interior was designed to be luxurious and sporty, with a focus on driver engagement. The dashboard layout is similar to that of the standard 6-Series, but with unique M-specific accents and instrumentation.
Chassis & Braking
The M6 LCI features a reinforced chassis and suspension components compared to the standard 6-Series. The front suspension utilizes a spring strut design with a transverse stabilizer bar, while the rear suspension employs an independent multi-link setup with a stabilizer bar. The braking system consists of ventilated discs at all four corners, with larger rotors and calipers compared to the standard 6-Series. ABS (Anti-lock Braking System) is standard. The M6’s chassis and braking systems are designed to handle the car’s high performance capabilities.
Market Reception & Comparison
The M6 LCI received generally positive reviews from automotive critics. Praise was directed towards its powerful engine, engaging driving dynamics, and luxurious interior. However, the SMG transmission was a point of contention for some reviewers, who found it to be less smooth and refined than traditional automatic transmissions. Compared to other trims in the 6-Series lineup, the M6 offered significantly higher performance and a more focused driving experience. Fuel economy was predictably poor, with combined fuel consumption of around 16.4 US mpg. Reliability was also a concern for some owners, with reports of issues related to the SMG transmission and cooling system.
Legacy
The BMW M6 (E63 LCI) remains a desirable and collectible car today. Its unique V10 engine and engaging driving dynamics have earned it a devoted following. While maintenance costs can be high, particularly for the SMG transmission, the M6 offers a driving experience that is difficult to replicate. The car’s value has remained relatively stable in the used car market, reflecting its status as a modern classic. The S85 V10 engine is considered by many to be one of BMW’s greatest achievements, and the M6 LCI represents the pinnacle of its development.
