This CTS is a serious sports sedan that requires no apologies. The fresh interior design is complemented with high quality materials. Engine choices include a 3.0l V6 (270-bhp), a 3.6l V6 (318-bhp) and the outrageous 556-bhp, 6.2l V8. Transmission choices include a 6-speed manual or automatic. Optional AWD and a limited-slip differential provide additional traction. In theory, the CTS competes with compact premium models like the BMW 3-Series and Mercedes-Benz C-class. However the larger proportions of the CTS are closer to mid-sized models like the Mercedes-Benz E-Class. Prices start in the low about $40,000s for a model with leather seats and an automatic transmission.
