The SLS’ presence in the Mercedes line is a throwback to the old 300SL. Both its shape and engine are exquisite. There’s only one version, the SLS 6.3 AMG, which is equipped with a 6.2-litre V8 that is capable of delivering an impressive 560 horses. With a long hood and gull wings, this is an exceptional car. It was a classic even before it was put on the market.
