Only Two Cadillacs Have V8s Now
We added a section to discuss the state of Cadillac’s current V8 lineup.
Imagine spending millions of dollars developing an entirely new V8 engine, only to kill it after just two years and 1,200 cars. That’s exactly what happened at Cadillac with the Blackwing V8, a twin-turbocharged, dual-overhead-cam masterpiece created to further distinguish the brand from the rest of the GM fold. Call it bad timing or a shift in strategy, but one of GM’s most ambitious engine programs in decades was gone almost as soon as it arrived.
A Vision Cut Short

By the early 2010s, Cadillac had already earned a reputation for building genuinely sporty luxury cars. The V-Series lineup had proven the brand could take the fight to BMW M and Mercedes-AMG, while cars like the CTS-V helped reshape Cadillac’s image from retirement-home transportation to something enthusiasts actually coveted. When former Audi executive Johan de Nysschen took the top job at Cadillac in 2014, following a brief and turbulent stint at Infiniti, he inherited a brand with momentum – and a chance to aim even higher.
De Nysschen’s goal was nothing less than turning Cadillac into a true rival for the German luxury establishment. That meant further distancing the brand from its GM siblings and investing in unique hardware that could justify premium pricing. The effort spawned the twin-turbocharged Blackwing V8 developed specifically for the CT6 flagship sedan, and planned follow-up models. Engineered from a clean sheet for maximum performance and efficient packaging, the V8 reportedly cost $16 million to develop.
The South African executive also pursued a broader cultural shift. In one of his most controversial moves, he relocated Cadillac’s headquarters from Detroit to New York City, arguing that a luxury brand needed to live and breathe luxury rather than operate alongside volume-market divisions. The strategy echoed a similar move he championed at Infiniti. De Nysschen also pushed Cadillac to prioritize long-term brand building over short-term sales targets, positioning it as an aspirational marque rather than a volume chaser.
That philosophy ultimately put him at odds with GM leadership. While Cadillac’s global sales rose during his tenure, thanks largely to strong growth in China, US sales moved in the opposite direction. GM and de Nysschen parted ways in 2018, and the Blackwing V8 was abandoned two years later. Cadillac largely returned to sharing more architecture and components with other GM brands while embracing an aggressive EV strategy that, at one point, was expected to make nearly the entire lineup electric, leaving only the Escalade as an internal-combustion holdout. Today, that plan has been softened considerably, with Cadillac once again developing a new generation of gas-powered vehicles.
A World-Class Platform And V8 Engine
Cadillac CT6 Body Structure (Omega Platform)Cadillac
The Blackwing V8 was designed to fit vehicles using a new Omega rear-wheel-drive platform, which was already in development before Johan de Nysschen arrived at Cadillac in 2014. In fact, the platform debuted just a year later beneath the CT6. The full-size sedan was sold in the US from the 2016 through 2020 model years, though it remains on sale in China and even received a redesign for 2024 while retaining the Omega architecture. However, weakening demand in China means its days there are likely numbered. No other production vehicle used the Omega platform, though rumors persisted that Cadillac once considered spinning off a three-row SUV from it, as well as a production version of 2016’s Escala concept, which actually used the Omega platform and packed a Blackwing V8.
The platform borrows heavily from GM’s smaller Alpha platform, which underpins the CT4, CT5, and the final Chevrolet Camaro. Extensive aluminum use helps keep weight in check, while heavier high-strength steel appears only where it offers clear advantages in crash performance or structural rigidity. The platform also supports advanced technology such as Super Cruise, Magnetic Ride Control, and rear-wheel steering. As a result, even fitted with the twin-turbo Blackwing V8 and the standard all-wheel-drive system and 10-speed automatic that came with the engine, the CT6 tips the scales as low as 4,407 pounds, or hundreds of pounds lighter than comparable German luxury sedans.

The Blackwing V8’s production run was even shorter than the Omega. Cadillac offered the engine for just two model years (2019 and 2020) and only in the North American-market CT6 Platinum and CT6-V. Known internally as the LTA, the 4.2-liter V8 features an aluminum block housing a forged-steel crankshaft, forged-steel connecting rods, and high-strength aluminum pistons. Its unusually small 3.39-inch cylinder bores allowed engineers to use smaller, lighter pistons, helping the engine rev more eagerly than its displacement might suggest. Other highlights include twin throttle bodies, direct injection, Active Fuel Management, and a variable-pressure oiling system. This ain’t your old man’s Northstar.
The Blackwing also employs a “hot-V” layout. While common among performance engines today, the design was still largely the domain of German luxury brands when the CT6 arrived. By mounting the turbochargers in the valley between the cylinder banks and integrating them with the exhaust manifolds, Cadillac reduced the engine’s overall size while shortening the distance exhaust gases needed to travel. The result is quicker turbo response and reduced lag.

The turbos generate up to 20 psi of boost, while an electronically controlled wastegate helps ensure 90 percent of peak torque is available from just 2,000 rpm, ensuring effortless thrust just off idle. Among the performance numbers are a peak 500 horsepower and 574 pound-feet of torque in the CT6 Platinum and 550 hp and 640 lb-ft in the CT6-V. The peak power and torque arrive at 5,000 and 3,400 rpm, respectively, and in the CT6-V helps deliver zero-to-60 mph acceleration in approximately 3.8 seconds and a governed top speed of 149 mph.
Cadillac Is No Stranger To Horsepower

On the topic of the Blackwing V8’s power output, we want to highlight some of Cadillac’s other achievements in the horsepower wars. Cadillac has been investing millions of dollars in its powertrains alongside General Motors to produce some of the most powerful engines the umbrella company has ever sold. Even though the brand’s modern, sporty luxury image didn’t fully come to fruition until more recently, it began with the introduction of the first CTS-V in 2004. This sedan changed the way buyers perceived Cadillac, partly due to its 5.7-liter V8 that made 400 horsepower and 395 lb-ft of torque.
By the mid-to-late 2000s, models like the XLR-V two-seater and STS-V sedan joined the V-Series ranks with their 4.4-liter supercharged V8s. With twelve total V-Series models under its belt, Cadillac knows a thing or two about high-powered cars. Of course, the automaker saves money today by sharing engines and platforms with other GM brands, and two of its quickest V-Series models are all-electric (the Lyriq-V and Optiq-V).
A Future Classic In The Making?

According to information compiled by GM Authority in 2024, Cadillac delivered just 285 examples of the CT6 Platinum equipped with the Blackwing V8 and 915 examples of the CT6-V, for a combined total of only 1,200 cars. Based on the reported $16 million development cost alone, that’s more than $13,300 per engine before accounting for the cost of actually building and installing it. Each Blackwing V8 was hand-assembled at GM’s Performance Build Center in Bowling Green, Kentucky, alongside the engines destined for the Corvette – something that isn’t cheap and makes its brief production run even harder to justify on paper. Fortunately, the investment didn’t go completely to waste.
While the Blackwing itself never found a second home, lessons learned during its development helped inform the dual-overhead-cam 5.5-liter V8 used in the C8 Corvette Z06 and, in twin-turbocharged form, the Corvette ZR1. The engines aren’t directly related. The Blackwing’s 4.2-liter V8 uses a longer stroke and prioritized effortless low-end torque for a luxury sedan, while the Corvette’s flat-plane-crank 5.5-liter V8 features a much larger bore and a sky-high redline in pursuit of outright performance. Even so, the Blackwing helped pave the way for today’s Corvette screamers.

For enthusiasts, the story’s end isn’t all tragic. Blackwing-powered CT6 sedans still surface on the used market, and most remain well below their original sticker prices, which hovered around $95,000 in the cars’ final year. Recent listings have shown CT6-V models trading in the $50,000-$70,000 range depending on mileage and condition, figures corroborated by findings on the CarBuzz Marketplace, while Blackwing-powered CT6 Platinum models can be found for even less. Given their combination of world-class engineering, genuine luxury, blistering performance, and extreme rarity, these forgotten Cadillacs look increasingly like future collectibles rather than used luxury sedans.
The Blackwing V8 Wasn’t The Future, But It Was Brilliant

Cadillac had a vision to become a true global luxury leader, but perhaps it was a vision rooted too heavily in the past. The industry has moved on, with powerful sedans with V8 engines giving way to SUVs and electrification, especially in China, the world’s largest car market by a significant margin. Still, the Blackwing name lives on as Cadillac’s ultimate performance badge, worn by the recently discontinued CT4-V and CT5-V Blackwing models and possibly set to return on a next-generation CT5. Meanwhile, the rare CT6s powered by the original engine will likely be remembered for years to come as the brilliant flash in the pan that they were.
Only Two Cadillac Models Have V8s Now

After decades of engineering some of the most impressive V8-powered sedans, coupes, and even wagons, Cadillac’s V8 lineup has been reduced to a mere two models. The CT5-V Blackwing is the coolest, with its supercharged 6.2-liter V8 that makes 668 horsepower and 659 lb-ft of torque. The muscle sedan can sprint to 60 mph from a standstill in just 3.4 seconds before surpassing 200 mph at its peak. Buyers can choose between a 10-speed automatic or a 6-speed manual transmission to feel more connected and engaged. The only downside is its price of $98,900 before destination and options.
The only other V8-powered Cadillac in 2026 is the Escalade. Technically, we could split the SUV into its regular and V-Series models to say there are three Cadillacs with V8s, but they all use the same 6.2-liter engine. The regular version uses a naturally aspirated engine like the one found in Chevy’s trucks and other full-size SUVs; it makes 420 hp and 460 lb-ft of torque, just like its Chevy counterparts. However, the V-Series model bolts a supercharger on top to surpass the CT5-V Blackwing’s outputs. Buyers can get an SUV with 682 hp and 653 lb-ft of torque for a minimum of $168,000.
