The 2019 Mercedes-Benz SL-Class is a luxurious two-door hardtop roadster. Part of the sixth generation introduced in 2012, it stands out for its elegance and performance. It's available in two trims: SL 450 and SL 550. The SL 450 has a 362-hp, 3.0L V6 biturbo engine, while the SL 550 boasts a powerful 4.7L V8 biturbo engine that develops 449 horsepower. Both models feature a 9-speed automatic transmission and rear-wheel drive. The roadster has keyless ignition and entry, a power retractable hardtop, leather upholstery, heated power-adjustable seats, an 11-speaker Harman Kardon sound system, and a COMAND infotainment system with navigation, Apple CarPlay, and Android Auto. Advanced safety features include forward collision warning with automatic braking, a driver drowsiness monitor, and Mercedes’ Pre-Safe system, which prepares the vehicle for an imminent crash. For 2019, the SL gained automatic high-beam control as a standard feature.
