Caddy considering tuner models, "Super V" series

Cadillac wants to sell ultra-high-performance tuner versions of its CTS-V, STS-V and XLR-V models, according to a published report today. The cars could be modded by Brabus, McLaren, Lorinser or Dinan, according to Edmunds. Cadillac product director John Howell told the publication that his company was considering turning to a European tuning house for the project because it conveys a more sophisticated image. Another possible lineup -- this one built in-house by Cadillac -- could go under "Super V" moniker. These models would have slightly more power than the current "V" models, and would enable Cadillac to compete with Mercedes AMG models and the BMW M-Series. Cadillac has long been rumored to be testing a CTS model with the 505-horsepower, 7.0-liter LS7 V8 from the Corvette Z06. The model would allow the CTS to rival BMW's new M5.
