To celebrate its 50th anniversary, Caterham unveiled its most powerful Seven ever; the X330 – a one-off supercharged model boasting a mind-boggling power-to-weight ratio of 600 bhp per ton. The stealthy, matt black concept is based around the range-topping CSR Superlight, but the addition of a supercharger to the four-cylinder 2.3-liter Ford Duratec engine increases power massively from 260 to 330 bhp – as the name suggests. That means the X330's equivalent power-to-weight ratio puts it ahead of the Bugatti Veyron (521 bhp per ton) and the McLaren F1 (559 bhp).
The near 35% power hike is achieved by a Rotrex C30-94 supercharger, which provides a boost characteristic that rises linearly with engine speed. In other words, although the X330's punch is greater at higher revs and speed, low-speed driveability isn't compromised thanks to an exceptional torque curve with over 221 lb-ft from 5500 to 7500rpm – 20 lb-ft more than the CSR260.
As the X330 is an engineering test bed, it is envisaged that some of the concepts will eventually find their way into production. To begin with the X330 will spearhead the British firm's R&D into bioethanol power in the coming months as it seeks to assess the viability of alternative fuel sources in road and race applications and cement a further 50 years of history for the legendary Seven.
In keeping with the Seven ethos of 'adding lightness', the extremity of the X330 doesn’t stop at moving parts. Lighter gauge steel is used in the trellis-style chassis and the use of new lightweight wheels together with an abundant use of carbon fiber for the bodywork all adds to the stealth appearance of this perfect 50th birthday present.

And how about another lightweight monster...
In road legal trim and riding on Dunlop Direnza tyres Michael Vergers smashed one the world’s most prestigious production car records in a Radical SR8. The 13-mile Nordschleife circuit lap record now stands at 6 minutes 55 seconds, a full 20 seconds off the next placeholder.
The Radical SR8 is powered by a 2.6-litre high-revving V8 engine, built in-house by Powertec, developing 360bhp. It generates enough downforce to be able to theoretically drive upside down and holds the outright lap record at Cadwell Park. With over twenty-five cars built and running, the SR8 is now a well-developed and reliable car.
The SR8 is not cheap, but where else in the world can you get a sports car which is designed around the world's only lightweight V8 engine which develops over 360bhp in standard form? The Powertec RPA enigne revs to 10,500rpm, has exceptionally good power and torque curves, and sounds gorgeous!
The SR8 is a available with either an ultra-lightweight Hewland JFR six-speed sequential gearbox, with plate-style LSD or the new uprated Quaife RQ2, with it's ultra-lightweight shift and torque-biasing LSD
The SR8 is comfy to sit in (a new, high-sided seat holds the driver in very securely) and all the controls come directly to hand. The pedal box and seat are fully adjustable, enabling drivers of all sizes to fit comfortably, which is just as well as the SR8 will pull 3g around a fast corner, helped by the sporty Dunlop 15'' / 16'' diameter slicks, designed specifically for the car.

The mildly tuned and customized EDO Murci LP640:
Edo Competition modified the Lamborghini Murcielago LP640 in the field of driving dynamics, optic and sound. Improvements that differ this edition considerably to the serial.
Aerodynamics is extremely important for a super sports car, especially, if you move it on the limit. In order to get more output on the rear axle, edo competition offers a rear wing with adjustable lip.
A unique sound is generated by edo competition high-flow muffler with stainless stell exhaust tips. A new exhaust butterfly valve control on
request with remote control will also be available. Thus, the sportive rear view is an outstanding side-effect.
More performance generates edo competition by changing the motor electronic with specially-adjusted mufflers and special high-flow air filters.
Particular customer requests give each Lamborghini a personal touch, e.g. it is possible to carry out different interior or multimedia tunings.
Features
Engine:
ECU recalibration
Special high-flow air filters
Newly designed high-performance catalytic converters
New exhaust butterfly valve control (remote-controlled on request)
New high-flow muffler
New stainless steel exhaust tips
Body:
Specially designed rear wing with adjustable lip
Wheels:
Custom paint on request
Interior:
Rear view camera
Tire pressure monitoring system
Carbon fiber interior trim
