We have no reason not to believe it. What design language can be perceived through the camo is uncannily Cadillac, and the spied car is low-slung with low-profile tires all-around, four exhaust tips, and far too much meat on its bones to be the equally-anticipated Cadillac ATS-V.
High-altitude testing is an important step for engine calibration especially, as the air is thinner – and thus, Oxygen more scarce – at higher altitudes.
We can likely expect the new CTS-V to debut early next year, and like the second-generation CTS-V, it will be propelled by a supercharged V8 taken or derived from the Corvette’s powerplant. Chances are that it will be the very same supercharged 6.2 liter LT4 V8 as found in the 2015 Corvette Z06, which should give this new “V” roughly the same 650 HP to play with.
You can see the spy shots for yourself, and watch TFL Car hunt down the camouflage-clad mystery Caddy at that outlet’s own website.
