As always, there were more than a couple of entries which had been modified by expert Cadillac tuners D3 , including a CTS-V Coupe with one extremely fast driver. How fast was he. Well, two impressive Mopar entries, a brand new 707 horsepower Dodge Charger SRT Hellcat and an SRT-10 Viper, got overtaken by the ‘V Coupe in one lap. We weren’t too surprised to see a D3-built and Cadillac Challenge-prepared CTS-V overtake a stock Charger Hellcat. Overtaking the Viper was a bit of a bigger task, however this driver/car combo makes it looks easy as can be. Revel in the Mopar-shaming, General Motors-powered race footage below, Cadillac fans.
