There’s a particular kind of heartbreak reserved for the almost. The kind where you build an entire track-focused package, re-engineer the suspension, retune the differential, and still come up two-tenths of a second short. That’s the story of the 2026 Cadillac CT5-V Blackwing with the Precision Package at Car and Driver’s Lightning Lap 2026, and it stings just as much the second time around.
The big Caddy laid down a 2:48.4 at Virginia International Raceway, a formidable lap from a 4,143-pound sedan packing 668 horsepower from its supercharged 6.2-liter V8. That time is fast enough to hang with C7 Corvette Z51s and decade-old Porsche 911 GT3s. But it wasn’t fast enough to dethrone the Porsche Panamera Turbo S as the quickest four-door around VIR.
GM’s Brandon Vivian, the engineering boss whose fingerprints are all over the Blackwing program, reportedly told Car and Driver he built the Precision Package with Lightning Lap specifically in mind. The GM performance teams test at VIR themselves. They know every corner, every camber change, every blade of grass waiting to catch an overconfident right foot.
The Precision Package itself is no gimmick. It includes redesigned front knuckles allowing more aggressive camber settings, stiffer rear knuckle bushings, retuned front suspension top mounts and rear cradle bushings, revised spring rates, modified damper travel, billet aluminum rear toe links, and a complete recalibration of Magnetic Ride Control, the electronic limited-slip differential, and steering. The package rides on Michelin Pilot Sport Cup 2R tires and stops with carbon ceramic brakes at all four corners. As tested, the car came in at $150,365.
So what went wrong? Grip. In Turn 1 alone, lateral grip dropped from 1.08 g to just 0.98 g, costing three-tenths of a second in a single corner. The team clawed some of that back through the Climbing Esses and the treacherous off-camber downhill section called South Bend, a corner that tests your faith in physics when you’re piloting over two tons of American muscle at the limit.
The revised Performance Traction Management algorithms showed promise early in each lap. The CT5-V Blackwing exited Turn 1 nearly four miles per hour faster than last year despite the reduced lateral grip, suggesting the electronic tweaks to power delivery were doing their job. But the system’s effectiveness fell off as the lap wore on.
By the final sectors, PTM was cutting spark to keep the rear tires from overwhelming what grip remained. The tires simply couldn’t sustain their performance over the full two-and-a-half-minute lap.
There is a small consolation for Vivian and his engineers, and Car and Driver was generous enough to point it out. The Panamera Turbo S that holds the four-door record is technically a hatchback. So if you’re being pedantic about body styles, and in this game pedantry is a survival skill, the CT5-V Blackwing does hold the sedan record at VIR.
The CT5-V Blackwing remains a Car and Driver 10Best recipient for the fifth consecutive year, and for good reason. It starts at $98,900, comes standard with a six-speed manual transmission, and represents what might be the last great gasp of the supercharged American V8 performance sedan. It’s a car that can demolish a racetrack and then cruise home on Super Cruise hands-free driver assistance without breaking a sweat.
But records are records, and this one still belongs to Stuttgart. The Blackwing came to VIR armed with every engineering weapon GM could throw at it, from redesigned knuckles and Cup 2R rubber to carbon ceramics and a brain trust of engineers who eat lap times for breakfast. It still wasn’t quite enough.
Sometimes two-tenths of a second is an eternity, and sometimes it’s just bad luck with grip on a given day. Either way, you can bet GM will be back.
