The 2011 Cadillac CTS Sport Wagon is essentially the same size as the acclaimed CTS Sport Sedan on the outside, but its unique cargo compartment nearly doubles carrying capacity, with 25 cubic feet of space behind the rear seats; and 53.4 cubic feet with the rear seat folded.

Available features include those of the well-appointed CTS Sport Sedan, including all-wheel drive, a 40-gigabyte internal hard drive, pop-up navigation screen and a hand-cut-and-sewn cabin.

A 3.0L DI V-6 is the standard engine and it's rated at 270 horsepower. Along with direct injection technology, the 3.0L engine employs variable valve timing to optimize power and fuel efficiency and reduce emissions.

The CTS Sport Wagon also offers an optional 3.6L DI V-6 engine that produces 304 horsepower. It is a larger-displacement member of the engine family that also includes the standard 3.0L engine. Both engines balance performance and efficiency while operating on regular unleaded gas. Hydra-Matic six-speed automatic transmissions back both engines. The CTS Sport Wagon offers optional all-wheel drive.

On the inside, the CTS Sport Wagon takes the successful formula of its sedan predecessor and adds a level of storage capability, making it a compelling alternative to an SUV or larger vehicle. The rear cargo area contains an integrated cargo management system that stows neatly under the floor when not in use. The standard power liftgate is operated by push-button and can be programmed to lift to a specific height.
