The engine’s rated at an impressive 550 horsepower and an eye-raising 627 lb-ft of torque, Cadillac said. That’s for the V-Sport; a 500 HP version will be available for other CT6 models,
Automotive News says. The V-Sport (while not a full-on V) is the first performance-oriented version we’ve had for the cushy CT6, and it will come with summer performance tires, a mechanical LSD, magnetic ride dampers and 19-inch Brembo brakes. This also marks the first time the CT6 has gotten eight cylinders; until now the top motor was a 3.0-liter twin-turbo V6.
