Emelia Hartford preps ZR1 for Pikes Peak

A Corvette build is turning into a real motorsport test now — not just a content car, not just a dyno number, and definitely not a drag-strip flex. Emelia Hartford said this week that she’s heading back to the Pikes Peak International Hill Climb on June 21, 2026, this time in a 2026 Chevrolet Corvette ZR1. That matters because the ZR1 is already a monster in stock form, but Pikes Peak asks a different question. It wants power, sure, but it really wants a car that can breathe, brake, and stay stable all the way to 14,115 feet. ### Why is this more than a YouTube build? Because Hartford isn’t just filming mods in a garage and calling it race prep. She’s on the 2026 Pikes Peak entry list in the Time Attack 1 class, which puts the whole project in a competitive frame right away. Last year she was already part of the event, so this isn’t a novelty appearance — it’s a return with a faster, more serious car. (corvetteblogger.com) ### Why use a ZR1 here? The C8 ZR1 gives her a huge ceiling to work with. Chevrolet’s new ZR1 makes 1,064 hp from a twin-turbo 5.5-liter V8, making it the highest-horsepower production Corvette ever and, basically, an absurd starting point for a hillclimb car. But Pikes Peak isn’t a top-speed oval. A 233-mph headline doesn’t win a mountain if the car overheats, fades the brakes, or gets sketchy in fast transitions.

Hartford’s first big move was building an unrestricted custom exhaust using Valvetronic components and a custom X-pipe — the “F1” exhaust she talks about in the prep video. The point isn’t just noise. Less restriction can help the turbo car shed weight and breathe more freely, and one secondary report says the setup cuts about 60 pounds.

The build includes a 1 5/8-inch chromoly roll bar, NASCAR-style door bars, and a race-seat test fit. Hartford even says this kind of full cage wasn’t in the Nürburgring-spec ZR1, which tells you how far this car is moving away from showroom trim. Once the door cards and interior pieces come out, reversibility gets a lot harder. (corvetteblogger.com) ### Why is Pikes Peak such a different problem? The course is 12.42 miles long with 156 turns, starting around 9,390 feet and finishing at 14,115 feet. So the car is climbing into thinner air the whole time. That hurts cooling and changes how aero and engine systems behave. Think of it like asking a supercar to do one giant qualifying lap while slowly losing the atmosphere it was tuned around. ### So is this a power build or a handling build? (corvetteblogger.com) It looks like a survival build first, speed build second. Yes, the ZR1 has huge power, and yes, the exhaust grabs attention. But the more important clues are the cage, seat, and the fact that this is being aimed at Time Attack 1 rather than some straight-line showcase. Pikes Peak forces every weak point into the open — cooling, braking, chassis confidence, driver visibility, all of it. (ppihc.org) ### What should people watch next? Watch for the unglamorous stuff. Tire choice. Brake package. Alignment. Cooling ducting. Ride height. Those details usually decide whether a Pikes Peak build is genuinely quick or just dramatic on camera. The ZR1 brings the headline number, but the mountain will judge the boring parts. (corvetteblogger.com) ### Bottom line? Hartford’s ZR1 project matters because it puts one of the wildest new American performance cars into a race that exposes weaknesses fast. If the build works, it won’t just prove the ZR1 is brutally quick. It’ll show the car can be turned into something disciplined enough for one of motorsport’s hardest sprints. (corvetteblogger.com)
