The Caterham Seven CSR | Part Two

Chassis

The new suspension system, which required adjustments to the chassis, paved the way for Caterham to revise the Sevens tubular spaceframe. The resulting overhaul sees a 25 per cent increase in torsional stiffness.

Interior

Internally, the new Seven CSR is barely recognisable from previous models.

To improve driver ergonomics, the traditional flat mounted toggle switchgear has been completely dispensed with, replaced by a driver focused curved fascia wrapped around an exposed steel tubular framework. Alloy style dials, gear-knob, handbrake and a bespoke steering wheel complete the stylish new interior, with room created for storage space in the central console and in the armrest.

Aerodynamics

Aerodynamic improvements have majored on the face of the famous Seven.

The introduction of re-profiled cycle wings, which are mounted even closer to the tyre to cut drag, and a new larger nose cone complete with a floor mounted chin, have combined to reduce the front end lift by 50 per cent. The net effect for the driver is a major decrease in high-speed understeer.

With one eye on the heat and humidity of some overseas markets, the new broader nose cone houses a larger radiator, and an underside intake and top positioned outlet duct to improve airflow management.

Wheels & Tyres

Working in conjunction with long-standing partner, Avon, the Caterham Seven CSR will squat firmly on Formula Three engineered 15-inch tyres, which measure a muscular 10 inches wide at the rear to assist traction and handling. Bespoke 15 spoke lightweight aluminium wheels will be fitted as standard.
