It’s been unforgettable since day one: Despite our totally respecting the break-in restrictions, the CT5-V Blackwing forcefully blew off its tires in a match of wheelspin on its first drive house in our long-term fleet. Sure, the circumstances had been chilly and moist, however the quantity of hooliganism on the prepared, even when utilizing nicely shy of this automotive’s full 668 horsepower, can virtually appear reckless. That is, if the CT5-V weren’t so communicative, predictable, and controllable, making it straightforward to ease previous the restrict with out shedding the deal with. But we did not but know the breadth of feelings that Cadillac’s V-8 sports activities sedan would rapidly sear into our reminiscence throughout this long-term check.
After the CT5-V Blackwing ran with far more expensive four-doors at our Lighting Lap observe showdown, and after we named every of Cadillac’s Blackwings to our 2022 10Best list, we ordered up each for a long-term check so we may grasp on to among the best-driving sports activities sedans ever created for so long as potential.
When it got here time to spec, we had to have a handbook. The last CTS-V, the CT5-V’s predecessor, went automated solely, however Cadillac righted that fallacious with the brand new automotive, and 62 p.c of CT5-V Blackwing consumers have chosen the DIY gearbox. Our automotive is a tasteful darkish blue known as Wave Metallic, which we might have most well-liked to pair with the $1500 bronze-colored wheels slightly than the bronze Brembo brake calipers it has. This automotive additionally has the $4100 Carbon Fiber 1 Package of aerodynamic add-ons, black-and-tan leather-based seats with carbon-fiber seatbacks ($6090), and the $1450 weight penalty that’s the sunroof possibility. Between that sunroof and the iron rotors (versus the carbon-fiber possibility), this instance weighs 115 kilos greater than the first CT5-V Blackwing manual we tested. Not surprisingly, this one ran 0.1 second slower to 60 mph and thru the quarter-mile, though 3.7 and 11.7 seconds, respectively, is bonkers for a 4200-pound sedan that may comfortably seat 5. At 1.02 g’s, skidpad grip almost matches that of the Corvette Z51, and the CT5-V’s 143-foot stopping distance from 70 mph beats each C8 Corvette we have examined, proof that the Blackwing-spec Michelin Pilot Sport 4S tires are significantly grippier than the off-the-shelf variations.
But these numbers did not come simply. The supercharged small-block V-8 that powered our automotive for its first 1700 miles did not survive the preliminary check session. After about 15 standing-start acceleration runs, the V-8 began misfiring dramatically, and the Caddy left on a tow truck. Somehow, combustion acquired too lean on the even financial institution, which led to cylinder scoring and necessitated a coronary heart transplant. We’ve outlined the carnage and findings from a teardown of that engine as soon as it made its means again to GM in a separate story.
Roughly six weeks later, the CT5-V was again, and we began a 1500-mile stint of restraint to break within the new V-8—protecting engine speeds under 4000 rpm, no wide-open throttle or fixed car speeds. The engine swap was coated beneath guarantee, though we acquired charged $50 for gasoline used to check the brand new engine after it was put in.
Back on the observe a second time, the CT5 was all bellow and zest, turning within the acceleration instances talked about above. Just after we had been considering all was proper as soon as once more in CT5-V Blackwing land, a cluster of deer appeared throughout one in all our remaining runs, and one bumped into the CT5’s flank, primarily damaging the passenger’s-side rear door.
If you thought that was unfortunate, the very subsequent day our long-term CT4-V Blackwing went to the observe, the place it startled one of many birds feasting on the recent kill. The fowl then swooped straight into the A-pillar of the lesser Blackwing, which was going 100-plus mph.
