Hennessey's Exorcist: Camaro Transformed into 9-Second Beast

I remember walking past a Camaro that looked tame and tidy, then watching it disappear down the strip like it had a rocket strapped to it. That mismatch between appearance and performance is the whole point of Hennessey’s Exorcist—a Camaro ZL1 that behaves like a supercar in plainclothes.

Chevrolet retired the Camaro not long ago, and chatter about its return keeps circling. Rumors point to a four-door revival built on GM’s Alpha 2 platform, sharing bones with upcoming Buick and Cadillac sedans, and possibly keeping a V8 under the hood. If true, that would shake up the muscle-car balance: Dodge and Ford would be forced to respond, and a new Camaro sedan could show up as a 2029 model, perhaps debuting in late 2028.

Why used ZL1s still matter

Until that future arrives, the fastest route to Camaro glory runs through the used market. Seek the sixth-generation ZL1. Straight from the factory it already packed a 6.2-liter supercharged V8 with 650 horsepower and 650 pound-feet of torque, low-12s in the quarter mile, and mid-3-second 0 to 60 times. That’s potent. But tuners don’t read brochures—they rewrite them.

Enter Hennessey. Their Exorcist package turns an already angry ZL1 into something that belongs in conversations with hypercars. The upgrades are extensive and focused on extracting power reliably: a larger supercharger, improved air induction, ported heads, custom camshaft work, upgraded valve train components, long-tube headers, a bigger heat exchanger, and a tailored engine calibration. Hennessey also offered dyno tuning and road testing during the build, plus a two-year warranty for peace of mind.

• Reported peak output: 1,000 brake horsepower and 966 lb-ft of torque.
• 0 to 60 mph in roughly 2.1 seconds.
• Quarter mile in about 9.6 seconds at 147 mph, top speed near 217 mph (350 kph).

Those figures put the Exorcist in rare company. It outruns many exotic supercars on the strip and gives Hellcats and other muscle icons a real run for their money. And it does so without the garish theatrics some competitors flaunt. Outside, subtle badging and a numbered plaque are the only clues to its secret identity. Drive it down the boulevard and most people will assume it’s a well-specced Camaro. Push the throttle and the secret shows itself.

There are trade-offs. Reliability and drivability depend on installation quality and maintenance. Fuel economy disappears. But if the point is raw, accessible speed that makes a statement on the drag strip and still fits in a garage, the Exorcist nails it.

Will Dodge’s Demon variants keep the crown for outright quarter-mile theatrics? Maybe. Will Ford and Chevrolet answer with new factory-built muscly sedans and faster trims? Time will tell. For now, anyone chasing shock-and-awe speed in a Chevy badge can find the Exorcist waiting in the used scene—sharp, savage, and strangely civilized until you ask for everything in one go.

Would you park one in your driveway?
