2016 Mercedes-AMG SL 65: In-Depth Review & Specs

The 2016 Mercedes-AMG SL 65 stands as a pinnacle of automotive engineering, blending ferocious performance with unparalleled refinement. This twin-turbocharged V12 roadster delivers 621 horsepower and 738 lb-ft of torque, propelling it from 0-60 mph in under 4 seconds while offering the comfort of a high-end grand tourer. Despite its age, it remains a benchmark for those seeking uncompromised luxury and speed.

Engineering Marvel: The Heart of the Beast

At the core of the SL 65 lies a hand-built 6.0-liter twin-turbo V12 engine, a masterpiece from Mercedes-AMG’s Affalterbach facility. This powerplant peaks at 621 hp at 4,800 rpm and unleashes 738 lb-ft from just 2,300 rpm, ensuring effortless acceleration across the rev range. Paired with a seven-speed AMG Speedshift Plus automatic transmission, it shifts gears with precision, though it lacks the dual-clutch swiftness found in lesser V8 models.

The transmission’s gear ratios start at 4.38:1 in first and taper to 0.73:1 in seventh, optimized for both sprinting and cruising. Rear-wheel drive channels this torrent of power, demanding skill from the driver, especially in dynamic modes where traction control can be dialed back for thrilling drifts.

Design and Aerodynamics: Form Meets Function

The SL 65’s exterior exudes aggression with its long hood, sculpted flanks, and massive grille. Its retractable hardtop allows seamless transformation from coupe to convertible in 17 seconds, even at speeds up to 31 mph. Aerodynamic aids like active flaps and a deployable rear spoiler enhance stability at high speeds, contributing to a top speed electronically limited to 186 mph.

Inside, the cabin is a sanctuary of Nappa leather, carbon fiber accents, and dual 11.6-inch COMAND screens. Standard features include heated and ventilated seats, a Burmester audio system, and adaptive cruise control. For 2016, upgrades like power-operated trunk lid, heated mirrors, and auxiliary audio input elevated everyday usability.

• Retractable hardtop for versatile open-air driving
• Premium leather upholstery with massage functions
• Advanced infotainment with navigation and Apple CarPlay compatibility
• Ambient lighting in 64 colors for personalized mood setting

Dynamic Capabilities: Beyond Straight-Line Speed

While the SL 65’s V12 dominates headlines, its chassis tuning reveals true sophistication. Adaptive damping adjusts in milliseconds via AMG Ride Control, balancing compliance on highways with sharpness in corners. The power-to-weight ratio of approximately 323 hp per ton edges out the SL 63, yet its 105 kg extra heft is noticeable in tight turns.

Braking is exemplary, with massive 15.4-inch carbon-ceramic rotors (optional) providing fade-free stopping power. In everyday driving, it glides silently; unleash it, and the exhaust roars like a symphony of fury. However, its grand tourer roots shine brightest on sweeping roads rather than twisty tracks.

Fuel Efficiency and Practicality: The Trade-Offs

No V12 escapes scrutiny on fuel economy, and the SL 65 is no exception. EPA estimates peg it at 14 mpg city, 21 highway, and 17 combined—worse than the V8 SL 63. Real-world figures plummet under hard acceleration, demanding premium fuel and frequent fill-ups for its 21.1-gallon tank.

Practicality includes a usable 13.8 cubic feet of trunk space with the top up, expandable via the power deck lid. Two-plus-two seating accommodates adults in front but relegates rears to occasional use. At an MSRP of $219,775, it’s for connoisseurs, not families.

Technology and Safety Features

The 2016 model brims with innovations. Magic Body Control scans roads ahead to preemptively adjust suspension, while Active Curve Tilting leans into bends like a motorcycle. Safety suites encompass collision prevention, blind-spot monitoring, and lane-keeping assist.

• AMG Dynamic Mode for customizable throttle, shift points, and stability
• 360-degree camera for tight maneuvers
• Pre-Safe system that tightens belts and closes windows pre-impact

These features underscore Mercedes’ forward-thinking approach, making the SL 65 safer than its brute persona suggests.

Ownership Experience: Costs and Reliability

Prospective buyers face steep maintenance costs—expect $5,000+ annually for services, tires, and brakes. Fuel and insurance add to the tally, positioning it as a hobbyist’s dream rather than a daily driver. Reliability is solid for a high-performance machine, though turbo and electronic complexities warrant extended warranties.

Resale holds strong among collectors, with low-mileage examples fetching premiums. Consumer feedback praises its smoothness and power but notes the thirst and weight.

Performance Breakdown: Numbers in Context

Quarter-mile times hover around 11.5 seconds, with relentless pull to the limiter. Highway merging feels otherworldly, as torque floods in instantly. Compared to contemporaries like the Bentley Continental GT, the SL 65 offers superior handling without sacrificing comfort.

In video walkarounds, its Designo paint and 20-inch alloys gleam, drawing crowds at shows. POV drives reveal a cockpit alive with turbine whooshes from turbos spooling up.

Market Position and Alternatives

The SL 65 crowns the SL lineup, starting from £173,295 in the UK equivalent. Alternatives include the SL 63 AMG for better efficiency or the Porsche 911 Turbo for track prowess. Yet, none match the V12’s soul-stirring presence.
