The main changes for the Cadillac CTS in 2005 came in the powertrain. First off, Cadillac actually downgraded the standard engine to a 2.8 L, 210 hp V6 engine. On the other hand, the CTS got a new 3.6 L trim featuring a 3.6 L, 255 hp V6 engine. Both the 2.8 L and 3.6 L trims have standard 6 speed manual transmission and optional 5 speed automatic. The 2005 Cadillac CTS has 4 doors, seats 5, and gets 17 mpg in the city and 27 on the highway. Standard features in both trims include air conditioning, power door locks, power windows, power seats, cd player, ABS brakes, and traction control. Shell out a little extra and you'll get stability control and a sunroof. Overall, reviewers applaud the introduction of the powerful new 3.6 L V6 engine. They also like the roomy interior and solid handling. However, the larger frame detracts a little from the ride. More importantly, experts say that the CTS just doesn't quite measure up to its overseas competition in the sport sedan market. In any event, consider the 2005 Cadillac CTS a solid domestic model with room to grow.
