Wirth Research is a group of engineering companies, founded by Nicholas Wirth in 2003, specialising in research, development, design and manufacture for the motor racing industry and other high technology sectors. The companies use virtual engineering technologies to enable a completely simulated vehicle design, development and testing process. The group is known for deviating from traditional physical development models; most notably neglecting to use a wind tunnel and instead relying solely upon computational fluid dynamics to design the 2010 Virgin Racing VR-01 Formula 1 car.
