Factory Five GTM wins Green Grand Prix 2nd Year in a Row!

Simon Hauger and His West Philly HS Team Win with 100+ MPG Run

I received more good news from Simon Hauger and his team of students running a modified GTM in the annual Green Grand Prix, held recently at Watkins Glen race track.

The West Philly High School GTM in action at the 2012 Green Grand Prix.

The team won their class averaging just over 100 mpg on the track on Friday driving and 92.5 mpg on Saturday for the road rally!

Simon reports: “The car ran great and just gets a ton of attention where ever we take it.”

Two weekends ago Lockheed Martin sponsored the team’s GTM as a part of their exhibit at the USA Science and Engineering Festival in Washington, DC.

The Green Grand Prix-Winning GTM is a modified version of Factory Five Racing's flagship supercar. The GTM is normally powered by a 400-650 hp GM LS corvette engine.

Lockheed was the title sponsor of the event and used the GTM as a headline feature. About 300,000 people visited over the three days.

“I’ve never seen that many people at a show before. We were totally swamped the entire time we were there. The response we got was amazing,” said Simon Hauger.

Congratulations to Simon and his team on another impressive victory!
