This sentence taken from the article has to be complete and total BS.

"Cadillac uses no artificial Torque Management like low-gear throttle dialback. Controlling the car is entirely up to you"

Saying that Cadillac uses no Torque Management for a car with 550 ft.\lbs. of torque and a 5 year 100k warranty cannot be accurate. C6 corvettes have HUGE amounts of TM, and don't have near the torque of this motor. Either the new automatic (6l90E) is completely bulletproof, or the above sentence is BS.

"They'll likely cost more than $1,000. Most options will be available a la carte, and Cadillac says a loaded CTS-V will be in the upper-$60K range."

Interesting.

Maybe it is done via traction or launch control rather than pre-emptive torque reduction?

Performance Traction Management has been discussed around here somewhere- I'll try and dig up a link.

It was developed for the World Challenge CTS-VR, and adapted for use on the ZR-1 and CTS-V. It gently dials back torque when wheelspin is detected, then adds it back in once the tires regain traction. I assume it can be defeated by entering the "everything off" mode (press and hold), just like the Stabilitrak.

Here's the "official" description from GM's Press Release:


Enabling the precise control expected in a high-performance sedan, the CTS-V features Performance Traction Management system, borrowed from championship racing teams. This technology uses advanced electronics to manage engine torque for optimal traction during acceleration. In situations such as acceleration from a stop or exiting corners, Performance Traction Management regulates torque delivery for the best possible launch.

Performance Traction Management uses the same sort of electronics as stability control programs such as Cadillac's StabiliTrak system, but applies it in a different manner. Rather than monitoring and controlling wheel slip to assist in stopping or slowing the car, PTM regulates torque delivery to instantly match the available tire grip for maximum acceleration.
