During the late 1980s and early 1990s, the Wesbank Modified Series in South Africa was where Audi's racing cars got a second lease of life. For homologation reasons, the mighty 90 quattro IMSA GTO, however, could not be used. Instead, a purpose built S4 GTO was created during the 1992 season, using a 100 S4 chassis with as many parts from the IMSA car as the regulations allowed. The resulting racer won at its debut and dominated the 1993 season. Believed to be the fastest of all of the period's five-cylinder racing Audis, the S4 GTO was reunited with its original driver Christopher Aberdein at this year's Goodwood Festival of Speed. Also out on the hill was this Penske PC23 Mercedes, which had been part of Roger Penske's great coup at the 1994 Indy 500. Exploiting a displacement limit exception in the regulations that favoured stock block engines, he had Ilmor create a Mercedes-Benz push-rod V8 from scratch just for the Indy 500. More powerful than any of his rivals' engines, Roger Penske had once again found the 'unfair advantage' and his team dominated the race. The featured PC23 was leading the race by 40 seconds when Emerson Fittipaldi crashed out with less than 25 laps to go. Now part of the Mercedes-Benz Museum collection, it was brought to full running order for Goodwood.
Few cars are as evocative as a Martini-liveried Lancia 037 Group B car. At Goodwood, one of the very last built works cars was demonstrated on the hill.
Hopefully working on a new generation of models, Lotus also continues to further refine the existing line-up and this Evora GT430 is their latest product. Powered by a 430 bhp V6, it is the most powerful Lotus production road car ever. Retaining the well honed Evora platform, the GT430 should be an absolute blast to drive.
