Review: 2026 Cadillac CT5 V Series Blackwing Precision Package
In many ways, Cadillac deserves heartfelt appreciation for allowing the CT5 V-Series Blackwing to survive this long with such a clear bloodline carrying over from a previous era of automotive technology. A massive supercharged V8 engine, zero hybrid or electric assist, four doors with a spacious rear seat, and even a six-speed manual gearbox all completely buck modern performance trends. The popularity of the Blackwing’s optional stick shift reveals how many sport sedan enthusiasts still exist, as over 62% of buyers choose the third pedal for rowing their own gears. Now, for 2026, Caddy adds a new Precision Package to the CT5-V Blackwing that ups the ante with reduced unsprung weight, sharper responses, and enhanced capabilities for longer sessions on track. I recently took a 700-mile road trip from Los Angeles to Laguna Seca and back in the pure-bred rear-wheel-drive variant, which can rip off burnouts well into third gear with the supercharger screaming and exhaust bellowing at full throttle. Though my trip sadly lacked any laps on California’s iconic racing circuit – I was there for a motorcycle track day – rest assured that the Blackwing with the Precision Package handles long-distance cruising, canyon carving, and life in traffic with equal aplomb, exactly as expected from the world’s greatest sport sedan. The new Precision Package specifically adds stiffer springs and a thicker front sway bar, as well as new steering knuckles and rear toe links to allow for a more aggressive alignment from the factory. But Cadillac went so far as to revise the suspension’s rubber bushing durometer, and then retuned the electronics for Magnetic Ride Control (or MagneRide) as well as the Blackwing’s many customizable drive modes to match the substantive hardware changes. And likely most critical: an upgrade from traditional cast-iron brakes to standard carbon-ceramics, which both shave weight and improve the prospects for longer track stints without suffering brake fade. My tester arrived in a slightly less than subtle configuration, with a light blue paint job Cadillac called “Drift Metallic” over a Jet Black interior and black 19-inch wheels. Unlike some lower-spec models in the lineup, especially the plasticky CT4, the CT5 comes with premium materials as expected of a classic Cadillac both inside and out: carbon fiber for the aero details that contrast nicely with the lightly flaked paint job, plus a healthy dose of the miracle material on the inside complemented by knurled metal trim, as well as a pleasing combination of physical switchgear beneath the expansive dash and gauge cluster touchscreen. As usual for any GM, most of the infotainment features snappy and crisp menus, including Apple CarPlay, not to mention the ability to easily play with the extensive drive modes available to unleash the Blackwing’s full potential. And first things first, before even hitting the road, I turned everything off and set out to torch those rear tires. At no point will 668 horsepower and 659 lb-ft of torque in such a luxurious, manual sedan ever get old. Pulling away from stoplights, I regularly chirped a tire in first gear even with traction control fully activated. Switching everything off just takes the beastly shove to another level, ripping through first and up into second gear almost immediately despite tall ratios, then kicking the tail out in third even at two-thirds throttle. The Precision Package equips Michelin’s dependable Pilot Sport 4 S tires on those optional 19-inch wheels – not too big but not too small – and at 4,123 pounds, the Blackwing also never seems slow even while feathering in throttle to keep the rear tires planted during hard acceleration. But only focusing on straightline speed – as much hilarity as those hard pulls always deliver – misses so much of what makes the Blackwing, and especially one with the Precision Package, such a uniquely enjoyable monster. As usual for GM once again, MagneRide nails the balance between stiff and cushy, with adjustable damper settings available via the center touchscreen. On better roads, I wound up preferring softer cushion with the steering in the middle setting for a bit less resistance when turning in, but then everything else turned up to the max. This provided more communication while hammering through transitions and allowed a bit more squat while launching out onto straights, which transferred more weight to the rear tires and helped to prevent too much tomfoolery given the brawny grunt available with even a mild flick of my right big toe. If there’s one main criticism to levy at the Blackwing, the 6.2-liter V8’s meager 6,500-rpm redline stands out as something of a disappointment. Such a low limit works in the CT5’s Escalade V big brother, for example, but space for another thousand revs on the tach might help to draw out a more raw edge from the lower and sleeker sibling. Luckily, almost unlimited low-end torque and a perfectly weighted shifter makes the act of climbing through the powerband and then flicking through gears an unmitigated joy. So many automakers still selling the increasingly rare species of manual cars tend to err on the side of lightweight and springy action, for both the shifter and clutch pedal, in the hopes that more customers will feel less intimidated by the mechanical nature of driving a more analog car. Not so here, as the short throws and perfect effort required to rack through the firm gates feel sturdy and solid, as befitting a prodigiously powerful sport sedan. By the time I reached Monterey, I wanted more than ever to hit Laguna’s infamously tricky Corkscrew and crest Turn 1 at full throttle before diving headlong through Turn 2 as sideways as possible. But of course, a 4,000-plus-pound four-door never belongs on track with two-wheelers, no matter how much I wanted to truly explore the Blackwing’s absolute limit with the new performance enhancements of the Precision Package. <- Gallery -> Whether the Precision Package truly makes sense for public roads wound up as something of a bigger question, especially for prospective buyers who may or may not plan on taking such an excellent daily driver out on the racetrack. The carbon-ceramic brakes never squealed when cold, in fairness, and will help prevent brake fade while hauling such a heavy vehicle around a track – but also do likely make up for a large percentage of the whopping $18,000 price for the entire option pack. As a counterpoint, carbon-ceramics do make sense for long-term ownership, since a good set can last for an order of magnitude longer than traditional iron rotors and pads. And yet still, in a four-door sport sedan with so much power, that also weighs so much, despite the excellence of MagneRide, the tighter suspension and retuned steering can almost border on too twitchy. Especially on rougher roads, the reduced mass at each corner and more aggressive alignment sacrifices just a bit of the luxurious cruiser character that makes a non-Precision Package Blackwing seem so planted and substantial. Unlocking that more aggressive personality seems worthwhile a fair amount of the time, and even with the uprated chassis, this Caddy never quite steps outside the magic window where comfort meets capability. But while hustling around LA or road tripping – at perfectly reasonable speeds, of course – on the long hours through California’s Central Valley, I occasionally found myself wanting a little less surface chatter transmitted through to the passenger compartment. I also averaged just over 20 miles per gallon over the course of the trip, though a slightly less exuberant exploration of every last horsepower and pound-foot may well return slightly improved fuel economy. Not that any other 668-horsepower vehicle will likely do much better, either, and certainly not with carbon-backed bucket seats keeping me swaddled both massaging and ventilating luxury through hot California summer. The carbon seats come as part of an $8,090 option package that includes custom quilting in the extensive semi-aniline leather. I need the ventilation and massaging but might skip out on the quilting. Similarly, Carbon Fiber 1 and Carbon Fiber 2 on the window sticker add $5,600 and $6,730, respectively, for the exposed weave on all the exterior goodies – I might pass on those and go with a more restrained gunmetal metallic, if only in the name of true sleeper status. All told, including the Precision Package, this Blackwing totaled up mightily above the $97,600 starting price to $140,840 as tested. Whether ticking every last box on the spec sheet or sticking with minimal options to get the most car for the money, any Blackwing seems worth snatching up before this generation of analog muscle finally says goodbye for good. Unless, that is, the next generation that Caddy already started teasing sticks with the same stellar recipe. Or even reintroduces the erstwhile station wagon variant, in the hopes of better taking the fight to Audi’s RS6 Avant and BMW’s M5 Touring competitors with a unique stick shift proposition that would entirely reset the terms of engagement.
