The 2009 Mercedes-Benz SL550 model is not a completely new version. It appears it’s a mid-cycle revamp of this roadster classic. The additions and enhancements to the SL550 result in improvements on a car that was one of the finest things on wheels in the first place.
The 5.5-liter V8 engine in the 2009 Mercedes-Benz SL550 remains untouched from previous models. The SL550 seven-speed V8 engine putts out 382 hp and 391 lb.-ft of torque with a 0-60 of 5.3 seconds.
Given the unique way the horsepower and the torque match up, driving the Mercedes-Benz SL550 feels like taking yoga. You and your SL550 are perfectly balanced.
The Dolby Digital 5.1 sound includes 10 speakers (510 watt output), a slot for music memory cards and even a Bluetooth interface. Music lovers can download up to 4 GB of your favorite music to a memory card and slide it directly into the sound system.
Another SL550 creature comfort is the AIRSCARF. It’s a heating system that’s built into both the driver and passenger seat headrests and efficiently circulates warm air around the head and neck at the push of a button.
The 2009 Mercedes-Benz SL550 offers a retractable hardtop that can be opened or closed in just 16 quiet seconds. The unique folding design offers an incredible large cargo area about 7.2 cubic feet when the top is down. The trunk holds 10.2 cubic feet when the top is up.
