1987-92 Ford Sierra RS500 Cosworth.

The Sierra RS500 Cosworth was the “evolution” version of the original RS Cosworth. The car featured a larger Garret T03B turbocharger, that was capable of handling much more turbo boost than the RS. In the car’s early competition days, power outputs on the race cars jumped from 360 bhp on the RS to around 450 bhp on the RS500. During the course of the RS500’s development over 5 and a half years, power ultimately peaked at around 620 bhp by the 1992 Bathurst 1000.
The RS500 can be identified from the RS by the second lip spoiler on the hatch and an addition lip on the front air-dam.
The RS500 made its racing debut at the Brno round of the 1987 World Touring Car Championship, were the Eggenburger finished first and second. The cars failed at their next appearance at Silverstone, but “won” the 1987 Bathurst 1000. The two Eggenburger cars were first and second across the line, but were later disqualified for irregularities with the wheel arches – which were found to be deeper than the standard car, allowing for greater wheel travel.
The Eggenburger Sierras finished up the 1987 WTCC by winning the Calder round in Australia, the Wellington round in NZ and the Fuji round in Japan. These wins contributed to Ford winning the manufacturers title in the 1987 WTCC.
By 1988, the Sierra were the cars to have in Group A racing. They dominated the 1988 ETCC, but failed to win the drivers championship due to the rules favouring class wins over outright wins. At the end of 1988, the FIA dropped the ETCC. The Sierras continued to be competitive in national championships, but the rules of the various championships started to move away from Group A regulations.
So the story moves to Australia. Australia continued to retain Group A rules long after the ETCC died.
The Dick Johnson Racing team was the first in Australia to develop the Sierra RS500s. At the start of 1988, a number of drivers were racing Sierras, but Johnson had a year’s head start on the others. As a result the DJR Shell Sierras finished first and second in the 1988 ATCC (Johnson 1st, team-mate John Bowe 2nd).
Johnson even took one of his Sierras to Europe to see how it compared to the Eggenburger and Andy Rouse Sierras. The Johnson/Bowe Sierra made a one off appearance at the 1988 Silverstone TT500, where it took pole and led until minor reliability dramas put the car out.
The Johnson team went to the 1988 Bathurst 1000 as favourites, but despite having a 3 car attack, suffered failures on two of the cars and only managed 2nd.
However, another local Sierra RS500 won. The B&H Sierra RS00 of Tony Longhurst/Thomas Mezera won, from Johnson and the Caltex Sierra of Colin Bond/Alan Jones.
In 1989, more teams switched to the Sierras for the ATCC. Long time Holden hero Peter Brock was amongst them, doing the almost unthinkable by switching to the Ford camp.
The Johnson team still won the 1989 ATCC, but faced extra competition from Brock, Glen Seton and Tony Longhurst.
The 1989 Bathurst 1000 was the final major Sierra victory (though a couple of other victories in Japan and NZ in lesser enduros followed). They finished 1st and 2nd, with the DJR Sierra of Dick Johnson/John Bowe beating home the Eggenburger/Moffat ANZ Sierra of Klaus Niedzwiedz/Frank Biela.
In Europe, the Eggenburger team won the 1989 Spa 24-hour race as well.
The Sierra continued to be developed and raced during the 1990 to 1992 seasons in Australia, but never quite had the same dominence they had in 1988-89.
The 1990 ATCC almost fell to a Sierra. In a close championship, there were three Sierra drivers (Dick Johnson, Peter Brock and Colin Bond) who could have won the championship at the final round, but they were beaten by Jim Richards, who was driving a Nissan Skyline. Then, despite overwhelming favouritism, the Sierra failed to win the 1990 Bathurst 1000. Best of the Sierras in the 1990 Bathurst 1000 was the second DJR Sierra of Paul Radisich/Jeff Allam, which finished second.
The Sierras did finally pick up a win in the BTCC in 1990 though, with Rob Gravett becoming the 1990 BTCC champion.
There were slim pickings for Sierra drivers in 1991, as the Skyline GTR dominated the Australian scene. By 1991, the BTCC had banned turbo cars, so there were no Sierras racing in Europe.
For 1992, there was a final glimmer of competitiveness. The Australian regulating body, CAMS, made some changes to the Group A regulations for the last season in Australia. The Sierras were allowed to use a 6-speed gearbox. Thanks partly to the 6-speed box and partly to the extra weight the Skylines had to carry, the Sierras managed to be much more competitive in 1992, with John Bowe claiming a couple of race victories.
The 1992 Bathurst 1000 was the last appearance in the Bathurst classic for a Sierra, and Dick Johnson took pole, before he and John Bowe finished second.
The final hurrah for the Sierra RS500s came in the 1992 Nissan Mobil series in New Zealand. Consistent performances in the two races saw Paul Radisich/Michael Preston win the Nissan Mobil series in the DJR Shell Sierra. A fitting end for the car’s career.


First race: 1987 World Touring Car Championship round – Brno 500, Czechoslovakia.
Last major race: 1992 Nissan Mobil 500 series, Pukekohe 500, New Zealand

First major win: 1987 World Touring Car Championship round – Brno 500, Czechoslovakia.
Last major win: 1989 Bathurst 1000 – Dick Johnson/John Bowe (note: two victories in the end of season Pukekohe 500 in NZ in 1989 and 90, plus victory in the 1989 Fuji 500 followed this, but these events did not have the stature or quality of entrants that Bathurst did).
