There was some speculation surrounding the powerplant hiding underneath the hood of those 2016 Cadillac CTS-V prototypes we’ve seen running around Milford, Michigan and putting in hot laps at the Nurburgring in Germany recently. Some thought its V8 would be twin-turbocharged, while others believed a supercharger was in order. Those rumors were put to rest yesterday when a video proved the latter, but does this come as good news or bad news?
Last year when we asked whether Cadillac should supercharge or turbocharge the third-generation CTS-V, the votes were overwhelmingly in favor of the twin-turbocharger route, taking 56 percent of the vote. Only 29 percent were in favor of the blower, so most of you will be a little disappointed by General Motors’ decision. The good news is it will most likely be a slightly reworked version of the 6.2-liter supercharged V8 to be found under the hood of the upcoming 2015 Corvette Z06, which makes a striking 650 horsepower and 650 lb-ft of torque.
The only real downside is the CTS-V may be less efficient than some of its twin-turbo its competitors, such as the Mercedes E63 AMG and BMW M5. The CTS Vsport variant of the car is much lighter than the 4,233 lb M5 however, so if the CTS remains slimmer in becoming a ‘V’ model, it could counteract the potentially thirstier engine. The LT4 V8 makes use of GM’s Active Fuel Management system, able to run on four-cylinders with no boost when cruising on the highway, a feature which will likely carryover into the CTS-V.
Either way we’ll end up with an extremely capable performance sedan, but are you happy the supercharger is sticking around for the next-generation car?
