And why is a high power-to-weight-ratio important?

And why is a high power-to-weight-ratio important? Because it dictates how fast the car accelerates flat out. Then, the carbon fiber body/chassis is also much lighter than most, as designers without Grand Prix experience tend to over-design their structures. The very narrow body without fully enclosed fenders also reduces weight. First, the power train is very light compared with mass-production units. Also, because the power train is light, the loads on the body are lower, so again less weight does not need to be built into the structure.

To save weight they have adopted a narrow coupe body with cycle-type front mudguards, and side-mounted radiators which flow into the rear fenders.4 liter engine, and a weight of under 1,100 lb.

On top of all that, Caparo, which produces a lot of components for the auto industry, have priced the Freestream at about $320,000 (176,000).

So how does the Caparo do it? Not with 2,000 bhp because the car would weigh at least 2. So long as the handling is good, the car will be very fast anywhere.Coming soon from England is the Caparo Freestream supercar, which will have a power-to-weight ratio of 1,000 bhp per ton! The Bugatti Veyron which has 1,001 bhp manages about 560 bhp per tonne, so how you can see that the Caparo is streets ahead of any other supercar in textile braided wire power-to-weight ratio, and that is what makes cars accelerate fast. Even so, this car changes the concept of exotic cars to where it should be - ultra-lightweight, compactness and exciting performance round twisty roads or circuits. The result is a pencil-slim car with 480 bhp at 10,500 rpm from a supercharged 2.5 seconds!! Holy mackerel that is fast. In fact, Bugatti has demonstrated that sheer power means a lot of weight, particularly in the transmission and brakes.5 tons, which would miss the target.

In fact, these are all factors used by Colin Chapman to design the early Lotus cars, and since used by all racing car companies.

To get a high power-to-weight-ratio you need a light car.

It has a very narrow cockpit, with the passenger sitting slightly behind the driver to reduce width, so this is more of a track racer or trackday special than a road car.

The whole design concept has been aimed at reducing weight, ore not putting in things that add weight. In other words, the Caparo Freestream really takes advantage of Grand Prix technology to build a supercar. This tremendous cornering power and braking would not be possible without the use of Grand Prix design principles. A car with a high power-to-weight-ratio can cover led firework bulb the ground quicker because it gets out of corners fast and accelerates up the straights faster.
.

The Caparo Freestream looks very unusual, but if you want sheer performance this is it! The makers say the car will hit 200 mph, and accelerate from a standing start of 100 mph in 5. Oh, and they also say that owing to the downforce available, the T1 will be able to corner and brake at 3g - incredible. Both the new engine and transmission are very light, as are all the components. And fast acceleration is very exciting, and can also improve safety of the car in some circumstances.

Lightweight solution

Instead of going for a big engine with masses of power, the designers, who worked on the McLaren F1, have gone for ultra lightweight and a compact V-8 engine based on F1 technology.

Yes... Greater power per weight always helps, because anything that’s not part of generating power or cushioning the body from shock is just a thing to drag around. Going up and down hills makes the point quite well. Now, explosive power is not required, but it’s relative — the steeper the incline, the more it matters. I’d think that for endurance running, one should have the lightest upper body consistent with general health and the strongest core and legs you can get without stress injury.
