A modified Cadillac CTS-V that ran roughly 1500 horsepower at Street Car Takeover Charlotte returns weeks later at the Atlanta stop with the dial turned up to 1700 horsepower — and a 7.62-second, 182-mph pass that made it the fastest CTS-V in the world. At 4,200 pounds, it is still carrying the mass of a full luxury sedan while running times that would embarrass far lighter dedicated drag cars. Watch to see the record-setting run for yourself.
