2014 BMW M6 Gran Coupe: Performance, Luxury, And Value

The 2014 BMW M6 Gran Coupe redefines high-performance sedans by merging ferocious acceleration, sophisticated handling, and everyday usability into one striking package. Powered by a twin-turbocharged 4.4-liter V8 engine producing 560 horsepower, this four-door coupe delivers supercar-like thrills while offering space for four passengers and a usable trunk. It’s a vehicle that excels on open highways and winding roads alike, though its hefty price tag demands careful consideration.

Engine and Performance: A Twin-Turbo Beast

At the heart of the M6 Gran Coupe lies BMW’s S63 4.4-liter twin-turbo V8, churning out 560 horsepower and 500 lb-ft of torque from as low as 1,500 rpm. This setup propels the car from 0-60 mph in just 3.7 to 3.8 seconds, with quarter-mile times around 12.0 seconds at 122 mph. The seven-speed M Dual-Clutch Transmission (M-DCT) shifts seamlessly, whether in automatic mode or via paddle shifters, ensuring power is always at the ready.

Launch control maximizes acceleration, though repeated hard launches can overwhelm the traction systems due to the car’s 4,400-plus-pound curb weight. On the road, the engine’s melodious growl builds with revs, accompanied by turbo whooshes that add to the drama. Top speed reaches 155 mph standard, or up to 190 mph with the optional M Driver’s Package.

Fuel economy lags behind the performance, rated at 14 mpg city, 20 highway, and 16 combined by EPA standards. Real-world testing yielded about 16.4 mpg on premium fuel, typical for this power level.

Chassis Dynamics: Agile Despite the Size

Despite its grand touring proportions—197.2 inches long with a 116.7-inch wheelbase—the M6 Gran Coupe feels surprisingly nimble. BMW M engineers stiffened the chassis by bolting the rear subframe directly to the body, added adaptive M Dynamic Damper Control shocks, and tuned the electronics for sharp responses. In Sport or Sport Plus modes, the suspension firms up, delivering catlike grip and precise cornering with minimal body roll.

Steering is direct and communicative, though some reviewers note electronic aids can feel intrusive unless fully disabled. The rear-wheel-drive layout shines on twisty roads, allowing throttle steering when traction control is off, but the car’s weight and length make it less ideal for tight lanes. Carbon-ceramic brakes, optional on test models, provide fade-free stopping power even after repeated hard use.

• Comfort Mode: Supple ride over broken surfaces, ideal for long cruises.
• Sport Mode: Balanced sharpness for daily driving.
• Sport Plus: Maximum aggression, though some find it overly sensitive at high speeds.

Compared to the M5 sedan, the Gran Coupe sits lower, enhancing the sporty feel but complicating entry/exit for taller drivers.

Design and Aerodynamics: Head-Turning Style

The M6 Gran Coupe’s fastback silhouette combines coupe elegance with sedan practicality. Aggressive lines, wide stance, and quad exhausts give it supercar presence, turning heads wherever it goes. Its longer body versus the two-door M6 adds rear-door access without sacrificing style. Matte-blue finishes, as seen in some tests, amplify its visual impact.

Aerodynamics aid high-speed stability, contributing to composed behavior at triple-digit speeds. However, the long hood and sloped roofline compromise forward visibility, making tight maneuvers challenging.

Interior Comfort and Quality: Luxury Meets Sport

Inside, the cabin exudes premium quality with rich leather, carbon-fiber accents, and Alcantara headliners in a two-tone scheme. Front seats offer extensive power adjustments, heating, ventilation, and aggressive bolstering for high-g driving. The driver-centric cockpit features intuitive controls, including a stubby gear selector and large paddles.

Ride quality remains tranquil even at speed, with effective noise insulation. However, rear space is tight—best for children or short trips—due to the coupe-like roof. The raised center tunnel and rear climate vents further limit middle-seat usability. Trunk capacity is 16 cubic feet (460 liters), adequate but smaller than rivals like the Mercedes CLS63 AMG.

Owners praise the ventilated seats, A/C efficiency, and Competition Package upgrades for transforming daily drives into engaging experiences.

Technology and Driver Aids

The 2014 model boasts BMW’s iDrive infotainment, navigation, and a high-quality audio system. Adaptive suspension, stability control, and multiple drive modes allow personalization. Electronic nannies modulate power smoothly, preserving fun without abrupt interventions.

Safety features include stability control, ABS, and optional adaptive cruise. Poor sightlines over the nose highlight the need for caution in urban settings.

Pricing, Value, and Rivals

Starting around $100,000, fully loaded examples with carbon brakes and luxury leather exceeded $116,000. This positions it above the M5 and against foes like the Mercedes CLS63 AMG (cheaper by £15,000 in some markets) or Audi RS7. While thrilling, its cost questions value versus more exotic alternatives.

Pros:

• Explosive acceleration and top-end power
• Refined ride across modes
• Premium, supportive interior
• Impressive high-speed stability

Cons:

• High price with options
• Cramped rear seating
• Thirsty fuel consumption
• Weight impacts agility in tight spaces

Long-Term Ownership Considerations

Maintenance on high-performance BMWs can be costly, with premium fuel mandatory and turbocharged engines requiring diligent care. Resale holds well for low-mileage examples, appealing to enthusiasts. Owners value its versatility for track days, road trips, and daily duties.

Final Verdict

The 2014 BMW M6 Gran Coupe excels as a grand tourer with sports car soul, offering unmatched power delivery and composure. It’s not the nimblest in class due to weight, but for open-road enthusiasts, few match its blend of luxury and velocity. If budget allows, it’s a rewarding choice over pure sedans like the M5.
