Corvette ZR1: How Chevy makes an exotic 1,064-horse supercar for 1/5th the price
Posted by Talbot Payne on May 31, 2025
Austin, Texas — All hail the members of the world’s elite club of 1,000-horsepower-plus supercars: Ferrari, Bugatti, Aston Martin, Lamborghini, Chevrolet.
Chevrolet?
The 1,064 Chevy Corvette ZR1 has joined European exotics despite a sticker price that is a fraction of its storied competitors. While the $174,995 ZR1, which Chevy made available for media testing at America’s formidable Circuit of the Americas Formula One course outside of Austin, is hardly affordable, it’s a bargain compared to, say, the 1,018-horspower, $850,00 Ferrari SF90 XX or 1,160-horse, $3.5 million Aston Valkyrie
Chevy’s secret sauce, GM executives say, is leveraging in-house engineering, a strong supplier base, and the General’s formidable army of manufacturing resources.
“First off, you might ask why the others are charging so much money,” smiled Vice President for Global Chevrolet Scott Bell in an interview here. “(This is) in our DNA. Corvette from the very beginning has been about having something that’s aspirational, but also attainable. And our engineers just continue to push to places I never dreamed.”
Unlike small volume production cars like the SF90 XX — of which only 1,398 are planned — the Corvette is built on a dedicated, automated assembly line in Bowling Green, Kentucky.
European exotics’ small numbers guarantee exclusivity and high resale residuals for wealthy collectors, whereas Chevrolet has long prioritized volume production, company insiders say, to make it an attainable supercar.

The in-house production is a point of particular pride for GM. When crosstown rival Ford, for example, set its sights on the supercar class with its mid-engine, carbon fiber-tub Ford GT, it followed the European exotic model. The limited production, $500,000-plus model was produced from 2017-2022 for a total of 1,350 units by specialty performance manufacturer Multimatic in Toronto (Multimatic is also producing Ford’s front-engine 2025 Mustang GTD supercar that’s estimated to start at $350k).
“(The ZR1) is made in Bowling Green, Kentucky, by all of our team members. It’s engineered in Detroit. So this is a big American story,” said GM President Mark Reuss. “It’s not farmed out. It’s not made somewhere else, and the starting price is something that we’re all very proud of.”
While the move to a mid-engine platform opened a bigger envelope for track-focused performance, program managers also anticipated a broader demographic of customers who had not shopped Corvette when it was a front-engine car. The mid-engine layout screamed sophistication.

“Corvette is based on a different business model than the exotics, because they are going for a bigger market,” said Steven Cole Smith, special projects editor for Hagerty. “Corvette has outperformed again with the ZR1. They are punching way above their weight with this car.”
Significantly, the Corvette eschews exotic, expensive, lightweight materials like a carbon-fiber chassis used by some if its peers to maintain the ZR1’s accessibility. At 3,800 pounds, the aluminum-chassis ZR1 is a thousand pounds heavier than, for example, the all-carbon Aston.
Chevy’s Bell said the scale of GM is key to the ZR1’s unique story.
“We do this car in some volume, which is pretty significant in this space,” he said. “When we went to the mid-engine, the aspiration grew, and we saw some new customers come into the Corvette family. The volume has helped us continue to invest in how far can we take it.”
In recent generations, the Bowling Green plant has pumped out 35,000 vehicles per year and the C8 has consistently hit that mark since 2021 with the ZR1 model now coming on line.

“We leverage the scale of this great company, General Motors, and everything we do with the brand Chevrolet allows us some things that are very efficient, very effective,” Bell said. “(We’ve got) a lot of variants of this car: Stingray, E-Ray, Z06 and now ZR1. “(In) Bowling Green, we learn from all of our facilities across the U.S.”
General Motors Co.’s sprawling manufacturing footprint brings with it a deep bench of efficient suppliers who help pump out over 2.5 million vehicles per year. With volume comes efficiency.
“It’s engineered into the car,” Reuss said. “Our supply base is really good. We get that relationship — that advantage — that’s gone on for many years. They know what we’re trying to do. They give us their best, we give it our best, and that’s pretty magical.”

That includes a comfortable, state-of-the-art interior that wouldn’t be out of place in a luxury European sedan. Stitched leather thrones in multiple colors including red, orange, and two-tone. Big digital screens that include high-tech features like a Performance Data Recorder, camera mirror and crisp graphics.
“That scale gives us permission to go after the ultimate in performance,” Bell said.
Similar features are found in other GM vehicles like the Silverado LT, High Country and electric trucks as well as Cadillacs. That interior grows more sophisticated for the ‘26 model year (ZR1 has a short tun as a 2025 model before adopting 2026 upgrades).
“The 2026 model year has an all-new interior . . . that’s even a step up from when we started (C8) five years ago,” Bell said. “The evolution is from learnings that we have across many platforms within our company.”

At the heart of Corvette models is an LT family of V-8 engines, from the pushrod, 6.2-liter LT2 in the base Stingray to the insane, overhead-cam, twin-turbo 5.5-liter mill in the ZR1. LT2 is an evolution of the pushrod engine that has powered millions of Chevy trucks over the years as well.
“Pulling this kind of horsepower out of a V-8 in a Corvette helps us in the truck world,” Bell said. “We are in a unique position.”
The ZR1 brings a race-developed, 5.5-liter engine — its sophisticated, high-revving, flat-plane crank design shared with Ferrari — that competes against the world’s best sportscar brands week-in and week-out on tracks across the globe.
“It’s a very proud moment (for) just the engine itself: 5.5-liter, flat-plane crank, twin-turbos,” Reuss said. “Those are the biggest (turbos) on a production car, period. Our front-engine cars were all supercharged, because we couldn’t fit the turbos. This is . . . one of the big reasons we went to mid-engine.”

Hagerty’s Cole Smith credits GM manufacturing with ZR1’s otherworldly performance numbers: “The turbos have a lot to do with the ZR1 capability. They had to have a base engine that was capable of holding up to that kind of stress.”
In addition to competing with the C8.R race car in the IMSA Weathertech (at the Detroit Grand Prix this weekend) and World Endurance Championship (the 24 Hours of Le Mans runs next month) series, Chevy has been torching track lap records with the ZR1 across North America this year — at the hands of its own engineers.
“The engineers that set the track records are the ones that work on these cars day in and day out,” Bell smiled. “All the racing we do, we can transfer that skill set into manufacturing.”
It may not cost seven figures, but the $175,000 ZR1 (along with its $100k Z06 and E-Ray siblings) looks like a million bucks and is attracting high-end customers. Bell says Corvette has responded with a more premium experience.
“The Bowling Green facility uses the best of the best of what we produce at GM, but we also ring in some of that hand-crafted culture as well,” he said. “For our upper-end customers there’s a museum there, there’s (track-testing) at Spring Mountain (Nevada), so we bring that exclusivity to people who are going to spend this kind of money.”
