Cadillac's first car-based sport-utility vehicle offered V6 or V8 power, and carried up to seven passengers with an available third-row seat. SRX was taller than a passenger car, but not as high as a truck-based SUV. Rear-wheel drive was standard. Optional all-wheel drive did not include low-range gearing. Available with either drive system was a 260-horsepower V6 or a 320-horsepower V8. The sole transmission was a five-speed automatic with a separate gate for manual shifting. ABS and traction control were standard. So were front side airbags and curtain side airbags for the first two seating rows. Available in a package that included all-wheel drive was GM's Magnetic Ride Control, which automatically adjusted suspension firmness based on the road surface. The V6 models used 17-inch wheels, versus 18-inch for V8s. Each SRX had a manual liftgate without a separate-opening window. Leather upholstery was standard. The split folding second-row seat slid fore and aft 4 inches to adjust leg room. The optional two-passenger third-row seat was power-operated to fold down flush with the rear cargo floor. Available in its place was a compartmentalized storage bin. Wood interior trim, heated front seats, and power-adjustable pedals were standard on V8s, optional with V6 power. Other options included rear DVD entertainment, Cadillac's UltraView sunroof with a 5.6 square-foot opening, and UltraViewPlus that added a vented glass panel over the third-row seat. Competitors included the Acura MDX, Infiniti FX, Lexus RX 330, and Volvo XC90. Cadillac also produced the larger, truck-based Escalade.
