Late last year, Mercedes-Benz confirmed that its seriously pretty CLS Shooting Brake concept would go into production, and our trusty spy photographers have now caught the first test mules out on the road near the automaker's headquarters. Aside from the addition of some shapely new sheetmetal at the car's hind quarters, not much is expected to change from the standard CLS-Class sedan range, and that's just fine with us.

Expect Merc's new twin-turbocharged 4.6-liter V8 to be the base engine at launch, with a CLS63 AMG Shooting Brake (be still our hearts!) coming down the pipeline. When Mercedes-Benz initially confirmed that the five-door CLS would go into production, we were told it would arrive sometime in 2012, and because these test mules appear to be nearly done with the development phase, we wouldn't be surprised if the final car debuts at the Geneva Motor Show next March (if not sooner).
