In 2006, McLaren developed the MP4-21 as a successor to the fastest car of 2005 – the McLaren MP4-20. Seven MP4-21 chassis were made.
Tighter packaging
The MP4-21 consists of 11,500 components, 90 per cent of which were changed from the MP4-20. These changes include tighter packaging to the rear of the car, a lowered and narrowed nose, and a reduction in the size of air intakes – including apertures in the main chassis – improving overall aerodynamics. This MP4-21 is in 2009 livery.
