Once renowned for having an exhaustive lineup of exceptional convertibles, Mercedes-Benz has significantly reduced the number of offerings in recent years. However, the iconic SL continues to shine. The AMG SL 55 4MATIC+ entry-level model is powered by a turbocharged 4.0-litre V8 developing 469 hp, while the AMG SL 63 4MATIC+ cranks it up to 577 hp. The all-new AMG SL 63 S E Performance uses an electric motor to reach 805 hp and 1,047 lb-ft of torque. For real.
