Overall Rating
Mercedes-Benz SL:

R107 Overview:
Mercedes-Benz SL (R107). With 378 Nm of torque, it offers ample pulling power. With a weight of 1585 kg, it falls in the mid‑range. Rear‑wheel drive offers dynamic handling and sporty feedback. Acceleration is good (0–100 km/h in 8.8 s). The top speed reaches 215 km/h. A two-seater convertible designed for open-top driving pleasure. Seating for 2 makes it ideal for daily use.
The Mercedes-Benz R107 was produced before Euro NCAP testing began (1997) and therefore has no official rating. Safety features are rudimentary by modern standards, lacking airbags, ABS (early models), or advanced driver-assistance systems.
