Official specs: 2009 Cadillac CTS-V makes 556 horsepower We knew what to expect, but now the specifications for the 2009 Cadillac CTS-V are official. Its 6.2-liter supercharged V8 produces 556 horsepower at 6,100rpm and 551 pound-feet of torque at 3,800rpm. Cadillac claims the CTS-V sedan will go from 0-to-60mph in just 3.9 seconds and through the quarter mile in 12 seconds flat. Top speed when equipped with the six-speed automatic transmission is limited to 175mph. Get the six-speed manual and youâ€™re free to run all the way to 191mph. Looks like Lutzâ€™s declaration that the CTS-V will put the BMW M5 on a trailer are right â€“ at least according to Cadillacâ€™s numbers.
