Former Formula One hopeful James Rossiter will make his American Le Mans Series debut later this month, having signed on to become the latest partner for Franck Montagny in Andretti Green Racing's ever-changing line-up.

The Briton, who came closest to achieving his F1 dream when he joined the testing strength at both Honda and Super Aguri, has inked a two-race deal with AGR that will see him partner former Super Aguri 'team-mate' Montagny for the ALMS events at Road America and Mosport.

Montagny joined Andretti Green's XM Satellite Radio Acura line-up when the team dispensed with veterans Bryan Herta and Christian Fittipaldi, and has been partnered in his two races to date by Marco Andretti and Indy Pro Series standout Raphael Matos. The Frenchman starred in practice at Mid-Ohio, but has yet to transform the team's luck - or results.

Sportscars have yet to feature strongly on Rossiter's CV, as the 24-year old concentrated on pursuing the F1 dream, starting his career in Formula Renault - chasing Lewis Hamilton and IRL hopeful Alex Lloyd to the 2003 British title - before graduating to F3 with the same Fortec Motorsport team that had taken him to FRenault success.

Having tested an F3000 car alongside future F1 drivers Nico Rosberg and Nelson Piquet Jr, Rossiter went on to again finish third in a British championship, having pushed Piquet and Adam Carroll throughout 2004. That performance was enough to earn him a berth in the F3 Euroseries with French outfit Signature-Plus, but the 2005 season was not a success as he finished a distant seventh in the championship.

He did enough to be noticed by Honda Racing F1, however, and was added to the team's roster of development drivers as he moved up to the World Series by Renault with Pons Racing. A learning year saw him finish 13th overall, but underline his talent with second place in the series' Monaco Grand Prix support race.

Rossiter was retained as one of Honda's test drivers for 2007, but the addition of seasoned F1 driver Christian Klien limited his opportunities and, in May, he was confirmed as a test driver for Honda-supplied Super Aguri. When the Leafield team folded early in 2008, however, his links to F1 were severed, and he was left without a race seat until being picked up by AGR.
