As has become the norm with high-performance factory Chevrolet Corvettes, the first production Corvette ZR-1 is heading to auction this month at Barret-Jackson's 47th annual Scottsdale event. And like those previous Vettes and a few Camaros, this is a charity auction. Barrett-Jackson will waive all fees as well, with all benefits being donated to the Stephen Siller Tunnel to Towers Foundation. Siller was a FDNY firefighter who lost his life on 9/11, and the foundation was started by his family to help first responders and seriously injured service men and women.

"Our 47th Annual Scottsdale charity docket features some of the rarest vehicles available for purchase in the world," said Steve Davis, president of Barrett-Jackson, in a press release. "But what makes these vehicles even more prized than their rarity is the fact they have been generously donated to aid people who are struggling and in need of help. We're grateful to team up with the many great organizations that are a vehicle for positive change in our world." The C7 Corvette ZR-1, as we all know, is the most powerful factory production Corvette ever made. Powered by a supercharged 6.2-liter V8 with 755 hp and 715 lb-ft of torque, paired to a seven-speed manual transmission, the new ZR-1 is literally an instant icon already.

The first C7 ZR-1 isn't the only special Corvette up for auction. Carolyn and Craig Jackson will also be auctioning off their personal 1988 Corvette 35th Anniversary Edition to help raise funds for the American Heart Association. Only 2,050 examples of this Corvette were built, and it's powered by a 5.7-liter V8 paired to an automatic gearbox.
