Redesigned for the 2009 model year, the SL-Class remains the most premium Mercedes roadster. The two available models for the U.S. market are the SL550 and SL600, while Europeans shoppers can also opt for the lesser SL350 and SL280.
The biggest changes to the SL line following the 2009 update are to the front of the car. The vehicle now has CLS-style headlamps to complement the new bumper and grille. Meanwhile, the taillights have been augmented with LEDs and a refined shape.
The SL550 and SL600's engines remain unchanged. The former has a 5.5-liter V8 delivering 382 horsepower at 6000 rpm and 391 pound-feet of torque between 2,800 and 4,800 rpm. The latter is motivated by a 517 horsepower twin-turbo V12, delivering 612 pound-feeet of torque from 1900 rpm up to 3500 rpm. Both models now have factionally better fuel economy.
The next-generation SL range include two AMG models: the SL 65 and SL63. The SL 65 will feature Mercedes' twin-turbo V12 �" producing 612 horsepower �" while the SL 63 uses a 6.3L V8 with 525 horsepower. We take a look at both vehicles in separate reports.
The car's steering system has been improved to feature a variable rack ratio, which adjusts in line with the steering angle, increasing sharply as soon as this reaches five degrees. All of which means that, compared to a steering system with a constant ratio, the driver does not have to move the steering wheel as much when cornering. More Details.......
