Caterhams have very poor aerodynamics due to the blunt windscreen, open-wheel design, and open cockpit. At very high speeds, lift becomes a problem. To combat this, the CSR has several features that reduce lift by 50%. The front cycle wings are fitted closer to the tires to reduce turbulence. In addition, they have a small lip that angles air upward and creates a small amount of down force. Also, the new front suspension scheme reduces turbulence and drag formerly caused by the spring and damper units. The biggest enhancement is the vent added on top of the nose cone. On previous Caterhams, the air from the radiator caused turbulence by knocking against the engine and other parts on the underside. A plastic panel behind the radiator now directs air straight out through the vent, creating down force and reducing turbulence.
