Lately, Caterham just seems to launch more and more amazing versions of the Caterham Seven. The new Caterham Superlight R500 combines the tuned 2.0 liter Ford Duratec engine with ultra-lightweight to produce a real stunner, but without the cost or complication of the V-8 in the
RS Levante.
The name, R500 indicates that this is derived from a racing model, and has a power-to-weight ratio of 520 bhp per tonne, or more realistically, 450 bhp per tonne with a driver aboard.
This is in the range of
exotic cars like the Pagani Zonda F and Maserati MC12, and Porsche Carrera GT.

Acceleration is at the same supercar level, with a 0-60 mph time of 2.9 seconds. This is hair-raising stuff, and very nearly as fast as you can get even if spend $500,000!
Light and simple
There is no magic here, just a logical extension of the passion for light weight and simplicity that Colin Chapman brought to high-performance cars more than 50 years ago, and which is now carried on by Caterham.
Beneath the hood is a Ford 2.0 liter Duratec engine, tuned by Caterham Powertrain to 263 bhp at 8,500 rpm, which is by no mens extreme by current standards. This is a very sporty engine, with good mid-range torque, but not too much low down. Peak torque of 177 lb ft is delivered at 7,800 rpm, emphasising that this engine is tuned for top-end power.
The engines drives through a six-speed manual gearbox to a limited slip differential. The Caterham sequential box is available as an option.
Caterham Sevens are based on a tubular frame with aluminum panels, and the Superlight 500 gets the latest reinforced frame, which is 12 per cent stiffer than earlier models, yet shows no increase in weight. The Superlight models are intended for competition and road use, so don't have any unnecessary components or systems.
Wishbones and de Dion axle
Although based on the double wishbone front suspension and de Dion rear axle of other models, a number of changes have been made to the Bilstein dampers, and front and rear anti-roll bars, while Eibach springs are used. Avon CR500 tires are mounted on 15-inch wheels.
To reduce weight, the front cycle-type fenders are carbon fiber as are the dash panel and lid for the luggage compartment. The seats are made from Kevlar. To ease entry and exit from the car, a Momo detachable steering wheel is fitted.
Also new is a fully electronic instrument set up. The price in the UK is a not unreasonable £36,995 (About $75,000)
