The G-Force chassis, which carried Buddy Rice to Indianapolis 500 glory in 2004, will be no more from this season, following the news that Elan Motorsports Technologies is to rename its IRL chassis.

From this season, the Target Chip Ganassi, Rahal Letterman and Fernandez Racing teams will use Panoz branded chassis' - named after the company's owner Don Panoz.

"We have decided we will use the name Panoz," CEO David Bowes said. "We needed to have a new branding strategy going forward that makes sense with our growth and which promotes the images and names as we want.

"We moved manufacturing to the US in the winter of 2002 and did all of our bodywork in-house. At that time tubs were still being built in the UK. A year later we moved the entire enterprise to our headquarters in Braselton, including our purchasing functions, design office and aerodynamics. As there is no part of G Force remaining any longer in the UK, we feel justified in making this change."

The company will use two names - Panoz and Elan - with Panoz the name of the products which the company will produce and sell itself while the Elan name will refers to the side of the company that performs engineering and manufacturing exercises for other companies.

"When we are manufacturing products for ourselves that we are selling from our headquarters, it is called a Panoz," Bowes explained. "Because we are growing and developing new business in aerospace and military/defense markets, we felt the need to differentiate and simplify.

"We are now an All American race car company. On those components where we are free to choose suppliers, more than 80 percent of the pieces involved come from American companies."
