20th Anniversary Hennessey HPE650 Camaro beats ZL1 to the punch

The Chevy Camaro ZL1 convertible was just announced this morning, and already it's been topped by John Hennessey. Why settle for 580 HP when you can get 655 HP and a promise of exclusivity?

To mark his 20th year of building insane cars, Hennessey will roll out this spiced-up version of the Camaro. The 20th Anniversary Edition HPE650 will be limited to 20 copies, each done up in black-on-black paint, and available as either coupe or top-dropper. You can even get one with an automatic, so help us.

Those extra ponies allow the HPE650 to punch through 60 mph at 3.7 seconds and pull a quarter-mile in 11.7 ticks. We assume the convertible version might be a touch slower in return for letting the wind blow freely through your mullet.
