When GM released the official horsepower rating for the Corvette ZR1, many expected the 2009 Cadillac CTS-V, which is also powered by the supercharged 6.2L small-block V8 but with a smaller Eaton compressor, to have a horsepower rating higher than Cadillac original stated.
No wonder it’s reportedly the fastest production sedan to ever lap the Nurburgring.
