It has been unforgettable since day one: Regardless of our absolutely 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. Certain, the circumstances had been chilly and moist, however the quantity of hooliganism on the prepared, even when utilizing effectively shy of this automotive’s full 668 horsepower, can virtually appear reckless. That’s, if the CT5-V weren’t so communicative, predictable, and controllable, making it simple to ease previous the restrict with out dropping the deal with. However we did not but know the breadth of feelings that Cadillac’s V-8 sports activities sedan would shortly 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 cling on to a few of the best-driving sports activities sedans ever created for so long as attainable.
When it got here time to spec, we needed to have a handbook. The last CTS-V, the CT5-V’s predecessor, went computerized solely, however Cadillac righted that incorrect with the brand new automotive, and 62 % of CT5-V Blackwing consumers have chosen the DIY gearbox. Our automotive is a tasteful darkish blue referred to as Wave Metallic, which we’d 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 Bundle 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.
However 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. In some way, combustion obtained too lean on the even financial institution, which led to cylinder scoring and necessitated a coronary heart transplant. We have outlined the carnage and findings from a teardown of that engine as soon as it made its manner 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 interrupt within the new V-8—retaining engine speeds under 4000 rpm, no wide-open throttle or fixed car speeds. The engine swap was lined underneath guarantee, though we obtained charged $50 for gasoline used to check the brand new engine after it was put in.
Again on the observe a second time, the CT5 was all bellow and zest, turning within the acceleration occasions talked about above. Simply 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 among our ultimate runs, and one bumped into the CT5’s flank, primarily damaging the passenger’s-side rear door.
Should 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 chook then swooped straight into the A-pillar of the lesser Blackwing, which was going 100-plus mph.
