Mercedes SL 500 2016 Review: V8 Performance And Luxury

The 2016 Mercedes SL 500 redefines what a luxury convertible can achieve, merging ferocious performance with everyday usability. Powered by a potent twin-turbo V8, it delivers near-supercar acceleration while wrapping occupants in opulent comfort, making it a standout choice for discerning drivers.

Powertrain and Performance: A Symphony of Speed and Smoothness

At the heart of the SL 500 lies a 4.7-liter twin-turbocharged V8 engine producing 335kW at 5250rpm and 700Nm of torque from 1800-3500rpm. This setup propels the car from 0-100km/h in just 4.3 seconds, a marked improvement over predecessors thanks to a new nine-speed automatic transmission.

The transmission’s closely stacked ratios and rapid shifts enhance responsiveness, while a ‘sailing’ function decouples the engine during coasting to improve efficiency, achieving around 9.0L/100km combined. In real-world testing, drivers noted its seamless operation across modes, prioritizing cruising refinement yet snapping to life in Sport+ for overtakes.

• Engine Specs: 4663cc V8, DOHC, 32-valve, twin-turbo
• Power: 335kW @ 5250rpm
• Torque: 700Nm @ 1800-3500rpm
• 0-100km/h: 4.3 seconds
• Top Speed: Electronically limited to 250km/h

Dynamic Select modes—Comfort, Sport, Sport+, Eco, and Individual—allow tailoring the experience. Comfort smooths out highways, while Sport sharpens throttle and steering for twisty roads.

Chassis Dynamics: Precision Meets Plush Ride Quality

The SL 500’s Active Body Control (ABC) suspension is standard, virtually eliminating body roll and delivering a planted feel through corners. Wide 285/30R20 rear tires provide massive grip, paired with a keen front end that inspires confidence.

Despite its grand tourer focus, it handles like a sports car when pushed, rewarding with powerful brakes and agile responses. Everyday driving shines with a compliant ride that absorbs imperfections, even on 20-inch wheels.

This balance makes it ideal for boulevards or backroads, far from the ‘soft’ label some critics apply.

Design and Aerodynamics: Timeless Elegance Evolved

Measuring over 4.6 meters long, the SL 500 boasts a sleek silhouette with a long bonnet and updated front fascia featuring a prominent Mercedes star in a chrome-accented grille. The folding metal roof deploys in 20 seconds at speeds up to 50km/h, transforming into a coupe-like cruiser with coupe-level refinement.

Optional wind deflector minimizes turbulence, enabling clear conversations at highway speeds. LED headlights and sculpted lines enhance its presence, blending classic roadster proportions with modern flair.

Interior Refinement: Luxury Redefined for Two

Inside, premium leather, wood trim, and metallic accents create a cockpit of sophistication. Seats offer heating, ventilation, and massage functions, with ample adjustment for long hauls. The infotainment system, centered on a high-res display, includes navigation, COMAND controls, and a Burmester audio setup.

Build quality is impeccable, with solid hush and a ‘cocoon’ feel top-up. Rear space is limited to luggage, but a powered frunk swallows 400 liters.

• Key Interior Features:
• Multi-contour seats with massage
• Ambient lighting (64 colors)
• Touchpad controller
• Apple CarPlay/Android Auto compatibility

Fuel Efficiency and Practicality: Surprising Thrift for a V8

Official figures claim 31.4mpg combined, though tests yielded 24mpg with mixed driving. The nine-speed and stop-start system contribute to 9.0-13.5L/100km in use. A 75-liter tank supports extended ranges.

Practical touches include a spacious trunk and easy-access controls, proving it’s no fair-weather toy but a viable daily driver.

Safety and Technology: Cutting-Edge Protection

Standard safety includes seven airbags, stability control, and attention assist. Optional packages add blind-spot monitoring, lane-keeping, and adaptive cruise. ABC enhances stability, while torque vectoring aids cornering.

Mercedes’ Pre-Safe system preempts collisions by tightening belts and closing windows. Euro NCAP awarded predecessors five stars; the 2016 model upholds this with refined electronics.

Ownership Costs and Rivals: Value in the Luxury Segment

Priced around £85,000 new, it competes with Porsche 911 Cabriolet, BMW Z4 M40i, and Jaguar F-Type. The SL edges in refinement and space, though rivals may feel sportier.

Depreciation is moderate for Mercedes GTs, with strong residuals if maintained. Servicing via official dealers ensures longevity.

Real-World Driving Impressions: From Highway to Highway Hero

Owners praise its boulevard-cruising poise and wind-in-hair joy. The V8’s rumble adds theater without drone, and ABC isolates from bumps. In 2026, used examples offer timeless appeal with modern usability.
