As the luxury crossover market continued to heat up in the last decade, Cadillac added the SRX to compliment the Escalade. Riding on the same platform as the STS, the SRX offers equal levels of performance and luxury. While the base setup is a V-6 powering the rear wheels, a 320-horsepower Northstar V-8 and all-wheel drive is available for enhanced performance and handling. The Cadillac SRX comes with a five-year/100,000-mile powertrain warranty and gets an estimated 20-23 mpg on the highway.
