The CTS was the first car to use the Sigma platform which debuted in 2003. Engineered on the famed Nurburgring in Germany, the CTS's handling was instantly heralded upon its introduction. The first CTS was powered by a 3.2L 220HP V6 that was derived from the 3.0L Opel V6. It was the first Cadillac in 50 years that offered a rear wheel drive manual transmission configuration. The CTS was also the first production Cadillac to utilize the "Science and Art" design philosophy which yielded bold angles and a unique look like no other car on the road.
My CTS is Raven Black 2003 model with manual transmission. The car was impressive from the factory but being a car enthusiast, I had to make it better. I have done several suspension, engine, and electrical modifications on the car. This site will focus on the in-car computer modification.
