Cadillac SRX Information. A luxury crossover SUV introduced in 2004, the Cadillac SRX is a rear wheel drive vehicle. The SRX is based on the Cadillac Sigma platform and has a variety of engine and interior options. There is an SRX as well as an SRX-V model, although the SRX-V model was not produced after 2005.
In a class not known for impressive fuel efficiency, every mile per gallon counts, and the SRXâs estimated 17 mpg in the city and 24 on the highway do it no favors in that category. To minimize your trips to the gas station, Cadillac has equipped the SRX with a 21-gallon gas tank.
