The Cadillac SRX launched into the luxury SUV market through its release in 2004 while using the Sigma platform and maintaining five-door functionality. The initial Cadillac SRX model from 2004 contained a motor installed front to rear alongside optional all-wheel drive (AWD) functionality coupled with rear-wheel drive (RWD) as standard. The Cadillac SRX offered standard transmission choices between five- or six-speed automatic until 2007 when the V8 models received the new six-speed automatic transmission for improved performance and efficiency. The Cadillac SRX allowed towing up to 4,250 pounds to meet multiple transportation needs. The Epsilon II platform became standard for the second-generation Cadillac SRX between 2010 and 2016 which featured front-wheel-drive as its primary setup. The AWD system had an electronic rear differential which improved traction capabilities. The 2012 model featured a 3.6 L V6 engine compatible with E85 flex-fuel together with transmission enhancements for improved fuel efficiency. The Cadillac SRX integrated advanced technology with the introduction of the CUE infotainment system which improved the driving experience in 2013. Customers need to purchase SRX products from official channels to maintain maximum security and performance levels for their vehicles. The ongoing reliability of the Cadillac SRX depends on original equipment manufacturer (OEM) parts to maintain its developmental path for both innovation and quality.
