You’ll have to look closely to find similarities between Cadillac’s CT4-V and its IMSA prototype race car, the DPi-V.R, but push a CT4-V hard on a racetrack and you might start thinking that the two share more than just their headlight and taillight signatures.
The CT4-V, like its predecessor, the ATS-V, rides on General Motors’ superstar Alpha platform. Cadillac softened the bushings for a better ride on the street, but the magnetorheological dampers counter any squish when it’s time to work. The chassis is unperturbed by intimate encounters with curbing. Don’t be shaken by the spooky high-speed oversteer when exiting the off-camber Turn 10; push hard to Oak Tree and you’ll find confidence in the outstanding brakes. Lean on the Continental tires and they’ll provide two weeks’ notice before quitting, and nothing is more informative than the Caddy’s precise, responsive steering.
Look beyond the magical chassis and it’s easy to undervalue the CT4 for not being a full-blown V-Series. Its 325-hp turbocharged 2.7-liter inline-four is hardly comparable to the 464-hp twin-turbo V-6 that bestowed the ATS-V sedan with an 11.7-mph advantage on the front straight. At the top end of the tach, the big-bore four labors like an overworked pack mule and groans just as much. From apex to apex, the 10-speed automatic hustles through gears to keep the engine in a plateau of midrange grunt. Tugging on the paddle shifters provides a more engaging experience, but doing so doesn’t shave any tenths, and it’s best to let this smart gearbox think for itself.
A 3:06.2 lap from Cadillac’s junior V is a solid showing, but a chassis of this pedigree begs for more muscle. We can only hope the forthcoming CT4-V Blackwing will bring the heat.
