SPEED.com's Marshall Pruett reports that Dragon Racing owner Jay Penske has filed a lawsuit against his IndyCar engine supplier, accusing Lotus Cars Limited T/A Lotus Motorsport of "contractual fraud." The report goes on to quote Penske's father Roger – lynchpin of the Chevrolet IndyCar engine program – as saying that he is aware that his son had conversations with GM about an engine deal, although he says he has not been a party to them.

Lotus announced last month that it was dropping two of its teams – Bryan Herta's Team Barracuda BHA and Dreyer & Reinbold Racing, which are expected to run Honda and Chevy engines, respectively. Losing Dragon's two cars for Sebastien Bourdais and Katherine Legge would leave the struggling British-run and Malaysian-owned manufacturer with just a single full-time IndyCar entry – HVM Racing's car driven by Simona de Silvestro. Jean Alesi is rumored to be running a Lotus-powered car at Indy run by Tyce Carlson's Fan Force United Indy Lights team, but is not expected to run any other events.
