3. IFR Aspid
How does 0-62mph in 2.8 seconds sound?
If the answer's positive, then read on. This is the Apsid, a Caterham-esque two-seater, created by former World Rally Championship engineer Ignacio Fernandez Rodriquez and his consultancy IFR Automotive.
Whereas his World Rally Championship creations were built for speed and not comfort, he is promising that the Aspid offers the best of both worlds, making it as practical in the city as it is on the open track.
Power comes from a 2.0-litre engine with 270bhp or, in supercharged form, 400bhp. Weighing just 700kg, the car is capable of 0-62mph in 2.8 seconds and 100mph in 5.9 seconds.
Prices will start from 75,000, although a long list of options can almost double the price. The show model is for preview purposes only, with the first production models ready later this year.
When's it due? 2009
