The dyno test for a car is much like the lie-detector test for a person. And it shows exactly what kind of power two new Cadillac variants, the 2014 XTS Vsport and the 2014 CTS Vsport, put to the pavement.
To begin, the XTS Vsport offers a twin-turbo 3.6L LF3 V6, with 410hp, and 369 lb-ft of torque to the crank. This power is then transferred through a six speed automatic transmission, through four wheels. Note: The engine of the XTS is placed transversely, unlike the more athletic CTS.
When put to the dyno at Church Automotive Testing in Wilmington California, the 2014 XTS Vsport put down solid numbers of 349hp, and 362lb-ft at all four wheels.
Then comes the 2014 CTS Vsport. It features the same 3.6-liter twin-turbo v6, but mounted longitudinally. That power is then sent to the rear wheels via a new 8-speed automatic transmission. The factory numbers for this sport sedan are a hearty 420 horsepower and 430 pound-feet. Not bad, considering there’s eventually going to be something above it.
When it came to dyno time for the CTS, 388hp and 435lb-ft were measured at all corners. That’s a horsepower loss of only 8 percent from the crank, and five more lb-ft of torque than what’s advertised. With this data logged, it looks like the LF3 is underrated. To compare, Edmunds once tested the outgoing CTS-V Wagon at 492 horsepower and 502 lb-ft of torque. We’re sure the next-generation CTS-V will raise the bar even higher.
