Until now Cadillac’s renaissance was incomplete. Engineers and designers had worked to update, transform, or simply improve nearly every model in the Cadillac lineup, with one glaring exception – the entry-level CTS. Yes, there was the CTS-V with hair-raising power, but it lacked the polished nature of the Escalade and STS. However, with the introduction of the 2008 CTS, the transformation is complete. Included with the new CTS are a new upscale interior, a revised yet still recognizable exterior, and a 300-horsepower V6. More important, at least to driving enthusiasts, is the availability of a six-speed manual transmission. Let the BMW and Lexus comparisons begin.
