Supercars, Division One, call them what you will, are among the most exciting racecars ever devised. Faster, lighter and more powerful than World Rally Cars, even their current restricted form they will out accelerate a F1 car: the benchmark for the standard 0-100km/h (0-60mph) measure is claimed by Swede Andreas Eriksson who recorded times in the 1.7s bracket last year. And yet these highly specialised machines are not, in motor sport terms, expensive. Commission a new car from one of the best and you need to think in terms of parting with something in the region of £200,000. A lot of money, but compare it with the £400,000+ price tag on Ford or Subaru WRC and compare the relatively long competitive life that a Rallycross car has, as well as the dramatically lower running costs – Irish Tarmac Rally Championship budgets are around £60,000 per event for a WRC – and Rallycross cars look like a motor sport bargain. It’s not only those who get to drive these cars who are captivated by them, all manner of motor sport fans will fall in love with the best cars – if only they can be persuaded to take a look in the first place. Died-in-the-wool rally fans may need to dragged kicking and screaming to their first Rallycross and The 2007 season will see second generation Citroën C4s from Most ‘mid-range’ saloons have grown over the last few years, race goers who don’t comprehend the idea of running the car KHM and Olivier Anne as well as a new version of the Fiesta the new Focus is bigger than the original version, the C4 bigger on dirt surfaces often need similar coercion, but if you can get ST from Andreas Eriksson’s Ford Team RS Sweden, Eklund than the Xsara, etc. The trend follows through to ‘compact’ these people to watch top class action, they are hooked, and Motorsport’s second shot at the Saab 9.3, Bergteamet’s new cars, the Fiesta and Clio both bigger now than in previous the wow! factor of the best cars is a very big part of what wins Volvo S40 and Helmia’s Renault Clio III. The latter pair are the incarnations – the Fiesta has track and wheelbase dimensions these people over. only truly new cars among the group, but as the S40 shares its only slightly different from the Escort Cosworth. 40 years ago a Porsche 911 was an unimaginably exotic platform with the current Focus, it’s a fair bet that it will work. Engine configurations could change too. Volvo drivers want and incredibly fast car. In that respect Rallycross cars have Assuming the rest have got their sums right and the second to try five-cylinder engine (perhaps in the C30, above) option – changed little. In the flesh, of course, today’s four-wheel drive, evolution of their cars work out better than the first, we are also suitable for the new Focus – and with WRC transmissions turbocharged, bespoke racecars have nothing in common with left with the Clio. Like the Fiesta, it is smaller than most of the becoming stronger, it seems certain that we will see transverse the 911, save that they, like it, are exciting to watch. established pace setters and could well point the way forward. engine installations tried again soon too.
