The BMW 3-Series is considered a benchmark in the compact luxury market. Like BMW, many automakers choose to add incremental sales with new body styles. The new Cadillac CTS coupe joined the well-regarded sedan and sport wagon models for the 2011 model year. The CTS Coupe features 2+2 seating for four passengers. A standard 3.6L V6 engine is offered with six-speed manual and automatic transmissions. Both rear-wheel-drive and all-wheel-drive models are available. For ultimate bragging rights, the high-performance CTS-V packs a 556-bhp supercharged V8 motor under the hood. Like the sedan, the CTS coupe is larger on the outside than the BMW 3-Series and Infiniti G, its two closest competitors.

Cadillac adds a coupe variant of the CTS for the 2011 model year. The two-door, four passenger coupe joins the sedan and wagon versions. Compared to the sedan, the coupe is shorter and wider. Power for most CTS coupes is provided by a standard 3.6L V6 engine. Both rear-wheel-drive and all-wheel-drive are offered. The high-performance CTS-V version is powered by a 556-bhp supercharged V8. The CTS-V also includes magnetic ride control and Brembo brakes.
