This 2004 Cadillac CTS-VRace Car is a unique racing prototype, crafted in 2003 by Pratt&Miller of New Hudson, Michigan. Originally designed for Cadillac's SCCA World Challenge series participation from 2004 to 2007, this American muscle car retains its high-revving 6.0-liter LS6V8 engine, mated with a Hewland five-speed dog-ring manual transmission and limited-slip differential for superior road grip.
