The first production-model 2013 SRT Viper GTSwas recently auctioned off for $300,000, company officials announced today.

According to Chrysler Group LLC, the supercar was auctioned off in California over the weekend with proceeds going to the Austin Hatcher Foundation for Pediatric Cancer, which helps children and families dealing with the challenges of pediatric cancer.

The Auburn Hills-based automakerofficially unveiled the vehicle earlier this year. The supercar returns with more power and performance from its all-aluminum, mid-engine 8.4-liter V-10 that delivers an estimated 640 horsepower and 600 lb.-ft. of torque.

“What an exciting and momentous occasion for the Austin Hatcher Foundation and the SRT brand,” said Beth Paretta, director of marketing and operations for the SRT Brand and Motorsports. “We’ve enjoyed a lot of attention since showing the all-new SRT Viper to the world just three months ago in New York; and now being able to use some of that interest in our flagship supercar to generate support for this deserving charity is simply outstanding.”
