The numbers here are simple: 550 horsepower, 550 lb.-ft. of torque, and a six-speed manual transmission. Were these numbers for a special edition Corvette, we’d be happy enough. But when they’re specs for the 2009 Cadillac CTS-V – a freakin’ 550-horsepower Cadillac! – well, we start to wonder if it’s time to dust off that old “Standard of the World” moniker. A limited-slip rear differential gets power to the ground, and Performance Traction Management uses the stability control sensors to maximize tire grip for acceleration.
