2015 Mercedes-Benz SL-Class builds on its enviable reputation as a superbly satisfying roadster with the addition of a new twin-turbo V6 model. Known as the SL400, this new model lowers the base price of the SL lineup, but without lowering the performance or prestige of this iconic luxury roadster.
New Features and Revisions
The new-for-2015 Mercedes-Benz SL400 adds a twin-turbocharged V6 to the SL-Class mix, along with a significantly reduced base price. On the other end of the spectrum, the SL65 AMG gets a new 7-speed automatic transmission to go with its 621-horsepower twin-turbo V12 engine.
