The car will also undergo aerodynamic changes and improvements to the traction control system.

Its purpose is to homologation a number of aerodynamic changes used in Group A racing.

During testing in early 1948 it was found that some aerodynamic changes had to be made to improve the handling of the aircraft.

Other new rules involve aerodynamic changes that should slow the cars slightly, Walker said.

The aircraft incorporates numerous structural and aerodynamic changes.

In addition to aerodynamic changes from recent years, the handling mechanisms have been altered significantly from only two years ago.

The race two years ago was so dull that Nascar mandated aerodynamic changes to promote closer racing.

Weight increases and aerodynamic changes led to later Spitfire Is having a lower maximum speed than the early production versions.

The new F393 featured major aerodynamic changes compared to its predecessor and introduced a monodamper front suspension layout.

The cabin entrance door was moved in front of the wing and other aerodynamic changes.
