The Car Connection (TCC) Web site reports that Cadillac will launch a new generation of high-performance cars in early 2003. TCC reports that the line will start with a 400-horsepower version of its new CTS sedan that uses a modified version of the LS6 engine used in the top Chevrolet Corvette Z06. The sporty Cadillac program is tentatively named CTSi, according to TCC, and a well-placed, senior GM source told the Web site that “the goal is to beat the (BMW) M5 in every turn.” The first CTSi model will go on sale about a year from now, TCC reports, citing GM insiders. TCC says the LS6-based V-8 will be matched to a six-speed manual transmission. Significant enhancements to the suspension are planned and the performance version should also be the first to get an upgraded interior to counter criticism of the CTS’ cabin. Cadillac hopes to produce performance versions of most, if not all, of its various car and truck models with the next upgraded car likely to be the new Seville, according to TCC.
