Caterham CSR

From Caterham press:

The Caterham 7 CSR is the latest evolution of the Seven design. It sees the long-awaited return of Cosworth to the road car market after a ten-year absence with two bespoke, high performance engines. The new model also benefits from the introduction of a fully independent rear, and inboard F1-style, front suspension plus major aerodynamic and chassis enhancements.

Launched in 2005, the CSR represents everything Caterham has learned about the Seven in over 3 decades of manufacturing the car.

2006 saw the introduction of the Caterham Cosworth Masters series, a semi-endurance formula for the CSR, which has underlined the new model’s sporting credentials. In September 2006 a road legal CSR260 lapped the Dunsfold test track, famously used by the BBC’s Top Gear, in an astounding 1:17.4, unofficially taking the record from the £300,000 Koenigsegg CCX.

The heartbeat of the Seven CSR is the new Cosworth developed 2.3-litre Ford Duratec engine. The all-alloy, four-cylinder twin cam unit will produce 260bhp and unrivalled levels of reliability and performance.

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 percent increase in torsional stiffness.

To improve driver ergonomics, the CSR260 offers an option of a driver focused curved fascia wrapped around an exposed steel tubular framework. Silver dials, fresh air vents, a bespoke steering wheel complete the stylish new interior and with room created for storage space in the central console and in the armrest.

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 percent. The net effect for the driver is a major decrease in high-speed understeer.

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.
