Back at the tail end of the 1980s, the Ford Sierra RS500 Cosworth was the ultimate touring car. Now, more than three decades later, it’s firmly back in fashion.
It has taken a while for historic touring car racing to embrace the Group A era. For many years, period touring car racing ended at 1966; the action was all about Ford Ford Mustangs, Mini Coopers and Lotus Cortinas, with later machinery largely ignored.
But little by little, the times have been a-changin’. The creation of the Gerry Marshall Trophy races at Goodwood gave the Group 1 cars of the 1970s a new impetus, and now, over the past two or three seasons, fresh life has been given to the Group A cars that raced right through to 1990.
It’s gathering momentum and the cars are spectacular, racing with both Motor Racing Legends and the Historic Sports Car Club.
Group A regulations were introduced to the British Touring Car Championship in 1983, allowing scope for major development from the road car. For the works Rover SD1s from Tom Walkinshaw Racing, the envelope was pushed to the point of being ripped open.
However, as the decade evolved, it was the 2.0-litre turbocharged Sierra that really set the BTCC pace, and Robb Gravett used it to become the final Group A champion in 1990.
For 1991, the BTCC moved to a single-class 2.0-litre formula – the start of what became the Super Touring era – and the RS500s became redundant.
Over in Japan, meanwhile, the Group A weapon of choice was the mighty four-wheel-drive Nissan Skyline GT-R, although this never really infiltrated the BTCC.
Thirty years later, the two top guns of Group A now regularly lock horns in an Anglo-Japanese contest in historic racing, and the result is fantastic, as 600bhp fire-breathing monsters do battle in some pretty capable hands.
Such is the level of interest in these cars that RS500s with strong provenance fetch £250,000 or more, but now you can have a newly built ‘continuation’ RS500 to period specification.
Back in the day, Alan Strachan was an engineer with touring car star Andy Rouse and built the RS500s that his team used. Now he’s offering newly built RS500s in the same trim for £185,000 and is building three of them this winter.
Meanwhile, Ric Wood’s CNC Motorsport outfit will build you a Skyline GT-R to period specification. He has already done four of them and will build more to order.
