Aerosmith singer Steven Tyler was first in the world to have a Hennessey Venom GT Spyder. He recently unveiled a few surprises at Barrett-Jackson in Scottsdale, where his 2012 Spyder raised $800,000 for charity. The Aerosmith vocalist passed the car over to a new owner.

Besides Steven Tyler’s Hennessey Venom GT Spyder, the new owner got a guitar signed by the complete Aerosmith gang.

Barrett-Jackson is world’s greatest collector car auction show in Scottsdale, Arizona. With this auction, the company helped raise funds for charities supporting US veterans, children, and medical research. The winning bid also included a week of vacation at Tyler’s Maui beach house.

The sale was for a good cause as all money will be directed to Janie’s Fund, a charity run by Tyler to support abused girls. This Fund was inspired by his 1989 song “Janie’s Got a Gun.”

Tyler first saw the Venom GT at its debut as a coupe at the 2011 Pebble Beach Concours d’Elegance. Tyler gave Hennessey a call and asked for a test drive while down in Hennessey Performance’s home state of Texas for the filming of “American Idol”. A couple of hours later, he ordered a convertible.

There were only five Hennessey Venom GTs for the 2013 model year.

This includes the first Spyder. The original price tag was $1.1 million. As for the car, the power comes from a twin-turbocharged 7.0-liter V-8 delivering 1,200 horsepower and 1,155 pound-feet of torque. There is a 6-speed manual transmission and the car reaches from 0-60 mph in just 2.7 seconds.

The car also features a custom audio system tuned by David Frangioni, a former audio engineer for Aerosmith and CEO of Audio One. The interior is black leather with red accent stitching and a teardrop eye logo like one of Tyler’s tattoos.
