Cadillacs entered the crossover utility vehicle market in 2004 with the introduction of the SRX. Directly competing against the Mercedes-Benz M Class, BMW X5 as well as the Lexus RX products, the seven-passenger 2004 Cadillac SRX was created with cues from the CTS. Available with rear-wheel and all-wheel drivetrains, the 2004 SRX luxury crossover offered the choice of V-6 or V-8 engine power.
A 3.6-liter V-6 engine generated 260 horsepower and was connected to a five-speed automatic transmission. Eight-cylinder propulsion for the 2004 Cadillac SRX came from a 320-horsepower Northstar powerplant featuring variable valve timing. Magnetic Ride Control was initially available on the all-wheel drive version of the SRX crossover in the 2004 model year. The technology was expanded to the rear-wheel drive model in 2005. In 2007, the Northstar V-8 equipped version of the Cadillac luxury crossover received a new six-speed automatic gearbox. Standard and optional equipment on the first-generation SRX included an UltraView sunroof, DVD-based navigation system with touchscreen control and eight-way power drivers seat.
Also added during the 2007 year to the SRX was a Bose 5.1 surround sound system and a Sport package. In 2010, the SRX was vastly changed assuming a smaller shape and more car-like attributes. The new SRX was also slightly less expensive than the previous model. Dropping the eight-cylinder powerplant, the 2010 Cadillac SRX could be outfitted with a naturally aspirated or turbocharged V-6 engine. The turbocharged version of the luxury crossover was dropped following the 2011 model year due to lack of customer demand. For 2012, a 308-horsepower direct-injected 3.6-liter V-6 engine became the optional engine on the Cadillac SRX. CUE (Cadillac User Experience) was added standard to the 2013 model of the crossover luxury vehicle increasing the connectivity provided on the SRX.
