The 2016 Cadillac CTS-V is already one of the most powerful four-doors on the planet, but could an even hotter version be in the works?

The current car develops a massive 640 horsepower and 630 pound-feet of torque from its supercharged 6.2-liter LT4 V-8, the same V-8 found in the Corvette Z06, but a well-placed source at Cadillac has revealed to Automobile that this isn’t the limit.

“I don’t know where it stops, but it’s not at 640 hp, that’s for sure,” the source said.

It’s thought Cadillac’s smaller ATS-V will eventually get a hotter ‘Plus’ model to do battle with the likes of the latest BMW M4 GTS and a planned Mercedes-AMG C63 Black Series, so it’s conceivable Cadillac may be planning something similar for the CTS-V.

How much extra power may a potential CTS-V Plus model pack? It will likely depend on what’s in store for new versions of the BMW M5 and Mercedes-AMG E63 due on the market in the next 12-24 months.

Stay tuned for an update.
