Sadly, the V8 powered ATS-V+ isn't going to happen. What's even worse is that this news was officially confirmed by Cadillac. Our colleagues at Motor Authority have spoken with David Caldwell, who is Cadillac's communications manager, and he told them that the rumors were a complete bogus.
He also said that given the fact that Cadillac has produced a car like the ATS-V that is extremely capable, it will be pretty much unlikely that it gets a new engine. What was also confirmed however is that the V8 will be powering another model in company's lineup, and it is the CTS-V.
This gets us pretty excited, because the car will be revealed this summer, according to Caldwell. It will be powered by the supercharged 6.2-liter V8 unit, which produces 640 horsepower (477 kW) and 855 Nm (630 lb-ft) of torque.
Caldwell also continued explaining why there won't be two cars having the same V8 powertrains. It is because there's simply "no need for the two V product lines to be twins". Since both V-Series models are extremely capable and premium, it is reasonable for Cadillac to "dial-in two types of performance character", one of which is smaller and one bigger.
It still would have been great if the V8 ATS-V+ have happened!
