The exact horsepower rating of the upcoming Camaro ZL1 has been a closely guarded secret, until now.

When initially unveiled at the Chicago Auto Show Chevy representatives were clear that while it shares its supercharged 6.2-liter V8 engine with the Cadillac CTS-V, it would make more horsepower than that model. More recently came reports that the number would exceed 570-hp. Now, news sources are reporting that; after speaking with Chevy engineers during a recent visit to GM’s Milford Proving Grounds, they can confirm an SAE rated 580-hp at 6000 rpm.

In addition to this the ZL1 model will also get track-capable cooling systems for the transmission, differential and brakes, not to mention some extra-grippy Michelin Pilot Sport Cup rubber. And, as previously reported, the car will also get GM’s incredible magnetic ride shock absorbers and the ZR1′s Performance Traction Management system.

We can't wait!
