First and foremost, the F1 required extensive modification to its bodywork in order to gain as much aerodynamic downforce as possible. Although it retained the same carbon-fibre monocoque as the road car, the entire exterior of the car was purpose-built. A much longer nose and tail, as well as a wider rear wing, were designed in order to maximize the amount of aerodynamic downforce, while the wheel arches were widened in order to allow for the maximum amount of grip from the tyres allowed by the rules. Ground clearance was also changed to front and rear, rather than the front and rear clearance of the 1996-spec car.
