Racing the Cadillac CTS-V in the World Challenge Series lets Cadillac put their cars where the action is.  Racing improves the breed, and by racing a Cadillac CTS-V that is not only production based but very close to the production model Cadillac can directly translate lessons from the track to the street.

Here is a direct comparison from the CTS-V Coupe to the CTS-V Coupe Race Car:

Slowing down for Racing the Cadillac CTS-V?

For some series and manufacturers, the race car has to be carefully tuned up to be competitive.  For WCRacing, Cadillac restricts the CTS-V engine output from the 556 hp that the street car makes to 460 hp for the race car.  Yes, when racing the Cadillac CTS-V Cadillac gives up almost 100 hp.

The racing engines are prepared by Katech.  They use the same 6.2L OHV V8 as the street car, but don’t have the supercharger.  As prepared they would make 520 hp, but are restricted to 460 hp for the series.

A big difference from the street car to make up for the power loss is weight.  The race car hits the track at 3,200 lbs plus rewards weight.  The street car weighs 4,222 lbs.  In the World Challenge, winning drivers get rewards weight to add to their car for the next race.  This helps balance the series even further during the season.  You can see the rewards weight each driver is carrying by numbers on the windscreen.

The complete vehicle specification for the racing the Cadillac CTS-V can be found on the World Challenge site here.

Cadillac is not afraid to throw down the gauntlet and put their cars on the track.  Racing the Cadillac CTS-V even with the series restrictions can give a very good test ground for engineering improvements in the street cars.    Racing the Cadillac CTS-V is also very entertaining.

Bravo Cadillac!
