Mercedes-Benz AMG SL63: Revealed!

Mercedes-Benz AMG SL63

Mercedes-Benz has revealed the Mercedes-Benz AMG SL63 together with their new Formula One car.

While Daimler was at it, though, it has taken the opportunity to show off its new Mercedes-Benz SL63 AMG Roadster for the first time. Based on the SL-Class that debuted just two months ago at the Detroit Auto Show, the SL63 packs AMG’s fast-becoming-ubiquitous M157 twin-turbo 5.5-liter V8 with 529 horsepower, but unburdened of 242 pounds of excess weight from the outgoing model (thanks primarily to the widespread use of aluminum and magnesium where the last model was made of steel), the new SL63 AMG can rocket from 0-62 mph in 4.3 seconds (4.2 with the optional AMG Performance Package) while returning 30 percent better fuel economy.
