Our Long-Term 2022 Cadillac CT5-V Blackwing Is off to an Unforgettable Start

It’s been unforgettable since day one: Despite our fully respecting the break-in restrictions, the CT5-V Blackwing forcefully blew off its tires in a fit of wheelspin on its first drive home in our long-term fleet. Sure, the conditions were chilly and wet, but the amount of hooliganism at the ready, even when using well shy of this car’s full 668 horsepower, can almost seem reckless. That is, if the CT5-V weren’t so communicative, predictable, and controllable, making it easy to ease past the limit without losing the handle. But we didn’t yet know the breadth of emotions that Cadillac’s V-8 sports sedan would quickly sear into our memory during this long-term test.

After the CT5-V Blackwing ran with far more expensive four-doors at our Lighting Lap track showdown, and after we named each of Cadillac’s Blackwings to our 2022 10Best list, we ordered up both for a long-term test so we could hang on to some of the best-driving sports sedans ever created for as long as possible.

When it came time to spec, we had to have a manual. The last CTS-V, the CT5-V’s predecessor, went automatic only, but Cadillac righted that wrong with the new car, and 62 percent of CT5-V Blackwing buyers have chosen the DIY gearbox. Our car is a tasteful dark blue called Wave Metallic, which we would have preferred to pair with the $1500 bronze-colored wheels rather than the bronze Brembo brake calipers it has. This car also has the $4100 Carbon Fiber 1 Package of aerodynamic add-ons, black-and-tan leather seats with carbon-fiber seatbacks ($6090), and the $1450 weight penalty that is the sunroof option. Between that sunroof and the iron rotors (versus the carbon-fiber option), this example weighs 115 pounds more than the first CT5-V Blackwing manual we tested. Not surprisingly, this one ran 0.1 second slower to 60 mph and through the quarter-mile, although 3.7 and 11.7 seconds, respectively, is bonkers for a 4200-pound sedan that can comfortably seat five. At 1.02 g’s, skidpad grip nearly matches that of the Corvette Z51, and the CT5-V’s 143-foot stopping distance from 70 mph beats every C8 Corvette we’ve tested, proof that the Blackwing-spec Michelin Pilot Sport 4S tires are considerably grippier than the off-the-shelf versions.

But those numbers didn’t come easily. The supercharged small-block V-8 that powered our car for its first 1700 miles didn’t survive the initial test session. After about 15 standing-start acceleration runs, the V-8 started misfiring dramatically, and the Caddy left on a tow truck. Somehow, combustion got too lean on the even bank, which led to cylinder scoring and necessitated a heart transplant. We’ve outlined the carnage and findings from a teardown of that engine once it made its way back to GM in a separate story.

Roughly six weeks later, the CT5-V was back, and we started a 1500-mile stint of restraint to break in the new V-8—keeping engine speeds below 4000 rpm, no wide-open throttle or constant vehicle speeds. The engine swap was covered under warranty, although we got charged $50 for fuel used to test the new engine after it was installed.

Back at the track a second time, the CT5 was all bellow and zest, turning in the acceleration times mentioned above. Just when we were thinking all was right once again in CT5-V Blackwing land, a cluster of deer appeared during one of our final runs, and one ran into the CT5’s flank, primarily damaging the passenger’s-side rear door.

If you thought that was unlucky, the very next day our long-term CT4-V Blackwing went to the track, where it startled one of the birds feasting on the fresh kill. The bird then swooped straight into the A-pillar of the lesser Blackwing, which was going 100-plus mph.
