No, this is not just a wagon, it's a Shooting Brake. As in the carts that used to be used to "break" in wild horses, training them to haul loads in an orderly manner. As in the carts that people used to go on hunting outings. Shooting Brake as in a 2012 Mercedes-Benz CLS with a wooden compartment floor and a load volume between 590 and 1550 litres. Don't worry about weighing this thing down, either. The new Brake has a twin-turbo 4.6-liter V8 with 408 horses (get it?) and 443 lb-ft of torque.
