The SRX by Cadillac's

The SRX is Cadillac's entry in the competitive mid-size luxury SUV market that includes competitors such as the Lexus RX350, BMW X5 and Mercedes ML-Class.

The SRX is based on GM's Theta Premium platform -- an enhanced version of the regular Theta architecture, which forms the basis for the 2010 Chevrolet Equinox and 2010 GMC Terrain.

The 3.0 delivers 260 horsepower at 6950 rpm and 221 pound-feet of torque at 5600 rpm, while the smaller turbocharged mill cranks out 300 horsepower at 5500 rpm and 295 pound-feet of torque at 1850 rpm.
