Since its founding it has also acquired several manufacturers, including famous Formula Ford builders Van Diemen and IndyCar Series constructor G-Force.

In 1999, changes in regulations led to the development of an open-top spyder for the LMP900 class, the Panoz LMP-1 Roadster-S. Like the GTR-1, the LMP-1 was a front-engine car.

The GTLM was designed for the "LM"GT2 class for slightly modified production sports cars.

Following the 2002 purchase of G-Force, Élan Motorsport Technologies took over production of the third generation IRL chassis.

[5] During the 2005 season, teams started to abandon the chassis (in favor of the Dallara) as it became increasingly unstable in traffic at Indy.

American Dream Motorsports entered a Panoz in the 2008 Indy 500 for Phil Giebler, but he crashed in practice.

It features a four-cylinder Mazda MZR engine mated to a six-speed sequential gearbox.

The DP01 was the sole chassis used for the Champ Car World Series in the 2007 season and the 2008 Long Beach Grand Prix.

The car weighed 675 kg and used a 750 bhp (560 kW) engine built by Menard Competition Technologies.

British race team Fluid Motorsport have taken over the former Snetterton Circuit in Norfolk, United Kingdom where they offer a parts and certification service for historic Van Diemen designs as well as compete in the British Formula Ford Championship.
