The Cadillac ATS-V sedan arrives track-capable from the factory next spring, powered by the first-ever twin-turbocharged engine in a V-Series. Rated at an estimated 455 horsepower (339 kW) and 445 lb-ft of torque (603 Nm), the 3.6L V-6 is the segment’s highest-output six-cylinder and enables 0-60 performance of less than 4 seconds and a top speed of more than 185 mph.
