Cadillac is preparing to unveil its 2016 CTS-V sedan at the upcoming North American International Auto Show in Detroit. We already knew the car will be a supercharged V8, thanks to clips of it testing at the Nurburgring, however a new report from AutoGuide hints that it will be a version of GM’s 6.2-liter supercharged LT4 V8 currently used in the 2015 Corvette Z06.
The 6.2-liter powerplant will reportedly produce 640 horsepower in the 2016 CTS-V, 10 less than the LT4 produces in the 2015 Corvette Z06. This small power reduction could be the result of a more restrictive exhaust system used on the 2016 CTS-V, which would give the four-door luxury sedan a quieter, more refined sound than the Z06.
If the 2016 CTS-V does produce 640 horsepower, it would have effectively trumped its rivals at Mercedes-Benz and BMW with the horsepower card. Mercedes’ latest E63 AMG produces 577 horsepower from its twin-turbocharged 5.5 liter V8, while the most powerful BMW M5 produces 575 horsepower.
We’ll have all the info on the 2016 CTS-V when Cadillac spills all the details in Detroit. In the meantime, you can satisfy your 2016 Cadillac CTS-V cravings with videos of it tearing up Germany’s Nurburgring during industry pool days.
