The production version of the Mercedes CLS Shooting Brake was spied recently during cold weather testing. The CLS Shooting Brake is a "station wagon" (estate) version of the four-door coupe, which aims to bring a little more versatility to Merc's elegant model range. Mercedes will sell the CLS Shooting Brake with a choice between several diesel and petrol engines. A high-performance CLS63 AMG version of the Shooting Brake is also expected. The new model does not yet have a direct rival, however, the Audi A7 Sportback does look like an alternative to the Mercedes CLS Shooting Brake.
