Evolution and Lineup Architecture
The 2018 model year marks the sunset of the sixth generation of the BMW 6 Series-based M vehicles. Offered in three distinct body styles—the two-door coupe (F13), the sleek four-door Gran Coupe (F06), and the retractable-soft-top convertible (F12)—the M6 lineup provided buyers with tailored compromises between rigid dynamic handling and daily grand-touring usability.
By 2018, BMW had streamlined the ordering process by baking many previously optional performance upgrades into the standard or Competition Package allocations. While the standard M6 offered an impressive array of luxury and speed, the availability of the Competition Package transformed the vehicle's driving dynamics significantly. The lineup catered directly to affluent buyers seeking a status-symbol grand tourer capable of supercar-rivaling acceleration without sacrificing traditional executive creature comforts.
Body Style Variants
Choosing among the three variants involves distinct trade-offs in weight, rigidity, and aesthetic presence:
- M6 Coupe (F13): The lightest and structurally stiffest of the three, featuring a standard exposed carbon-fiber roof panel that lowers the center of gravity and optimizes handling balance.
- M6 Gran Coupe (F06): Adds a stretched wheelbase and two rear doors, improving rear-seat accessibility while maintaining a dramatic, low-slung roofline and aggressive rear haunches.
- M6 Convertible (F12): Features a multi-layer fabric soft-top that folds electronically, offering open-air V8 acoustics at the expense of a heavier curb weight and reduced trunk capacity.
Powertrain and Performance Specifications
At the heart of every 2018 BMW M6 beats the formidable S63TU engine—a 4.4-litre, 32-valve, twin-turbocharged V8 featuring a hot-V configuration where the twin-scroll turbochargers are nestled inside the cylinder V-bank to minimize turbo lag and optimize throttle response.
In standard form, this power plant generates 560 horsepower between 6,000 and 7,000 rpm, alongside a massive wave of 500 lb-ft of torque available from a lowly 1,500 rpm all the way up to 5,750 rpm. Power is routed to the rear wheels through a lightning-quick 7-speed M Double Clutch Transmission (M-DCT) equipped with Drivelogic shift-speed adjustments, complemented by an Active M Differential that continuously varies lock-up between the rear wheels to maximize traction.
The Competition Package Advantage
For drivers demanding sharper reflexes and extra muscle, the optional Competition Package elevates output to 600 horsepower while maintaining the same 500 lb-ft torque ceiling. Beyond the 40-horsepower bump, the package introduces a comprehensive suite of hardware enhancements:
- Revised Suspension Tuning: Stiffened springs, dampers, and anti-roll bars alongside a lowered ride height.
- Direct Steering Calibration: A more direct steering ratio tailored for enhanced feedback during aggressive cornering.
- M Sport Exhaust System: Features black chrome tailpipes and modified internal baffling for a throatier, more aggressive exhaust note.
- Unique Alloy Wheels: Distinct 20-inch lightweight forged M wheels wrapped in performance rubber.

Exterior Styling and Aerodynamics
The exterior design of the 2018 M6 balances muscular aggression with refined elegance. Distinctive M-specific styling cues separate it from standard 6 Series models, starting with the aerodynamic front fascia featuring massive air intakes designed to feed oil coolers and intercoolers. The kidney grille bears double slats carrying the iconic M6 badge, a subtle indicator of the vehicle's high-performance pedigree.
Along the flanks, sculpted character lines flow from functional front fender air breathers bearing M side gills, sweeping back toward muscular rear wheel arches. The lightweight carbon-fiber roof on the coupe variant features a distinctive center recess that channels air cleanly over the vehicle. At the rear, an integrated trunk-lid spoiler, aerodynamic diffuser, and signature quad exhaust tips establish a wide, planted stance.
Interior Craftsmanship and Technology
Stepping inside the 2018 BMW M6 reveals a cabin draped in premium materials, dominated by extended Merino leather upholstery, carbon fiber or fine-wood interior trim accents, and an Alcantara headliner. The cockpit is driver-centric, featuring standard 20-way power-adjustable M multi-function seats that provide exceptional lateral support during hard cornering while remaining comfortable over long road trips.
Infotainment and Convenience
The dashboard centers around BMW’s iDrive system (version 6.0), displayed on a high-resolution freestanding central screen controlled via the rotary iDrive controller and physical shortcut buttons. Key cabin technologies include:
- Head-Up Display (HUD): Features M-specific graphics, displaying vehicle speed, gear selection, and a multi-color tachometer shift light indicator.
- Audio Systems: A standard Harman Kardon surround-sound system, with upgradable options for a high-end Bang & Olufsen High-End Surround Sound system featuring illuminated acoustic lenses.
- Driver Assistance: Available packages added active blind-spot detection, lane departure warning, frontal collision warning with pedestrian mitigation, and side- and top-view parking camera systems.
Driving Dynamics and Ride Quality
Weighing in north of 4,000 pounds across all variants, the 2018 M6 is a heavyweight grand tourer rather than a featherweight track car, yet its dynamic capabilities belie its sheer mass. The chassis utilizes aluminum extensive double-wishbone front suspension and integral-V rear suspension, paired with Adaptive Drive electronic dampers that adjust stiffness in milliseconds based on road conditions and driving modes.
Drivers can independently configure steering weight, throttle mapping, transmission shift aggressiveness, and damper firmness via the iDrive menu or by saving preferred settings to the red M1 and M2 buttons mounted directly on the steering wheel. In Comfort mode, the M6 swallows highway miles with luxurious compliance. Selecting Sport Plus transforms the vehicle into a roaring, responsive performance machine, though the car's physical footprint requires conscious line placement on narrow backroads.
