Brian Muir in an Alpina BMW 3-litre CSL during the May 1973 Spa 1,000km.
He shared the car with Hans Stuck, the pair finished second in class, eighth outright, immediately behind the sister Alpina machine raced by Niki Lauda – and Hans Stuck! The race was won by the Mirage M6 Ford prototype crewed by Derek Bell and Mike Hailwood.
Muir is too often forgotten in conversations between enthusiasts in Australia about successful internationals. He was a much respected figure in touring cars and sportscars in the UK/Europe for the better part of 30 years after leaving Australia for the UK for the second time, as winner of the ‘Smiths Industries Driver to Europe Prize’ in late 1964.

Brian had a terrific year in 1973, he raced Alpina tuned BMW CSLs in both the British Saloon Car Championship and the European Touring Car Championship.
In the UK the battle for outright honours was fought between Frank Gardner’s legendary SCA European Freight Services Chev Camaro Z28 and fellow Sydneysider, Muir.
Gardner won the title with wins in six of the eight rounds he contested, Muir won at Silverstone and Brands Hatch to finish fifth overall behind better performing smaller-capacity class cars.



Things were better in Europe though.
Brian and Niki Lauda won the first ETCC round at Monza – the Monza 4 Hours – in March leaving four Ford Capril RS2600s in their wake.
Muir was second at the 4-Hour Austria Trophy at the Salzburgring sharing with Toine Hezemans, and again at the following round, the 500km of Mantorp Park, Sweden. Ford Capri RS2600s won both races crewed by Dieter Glemser/John Fitzpatrick and Glemser/Jochen Mass respectively.
Paired with Alain Peitier, Muir’s car failed at the Nurburgring’s Grosser Preis der Tourenwagen with bearing trouble while running the just homologated 3.5-litre engine. It was the first of many bearing problems that year.
In a race – make that series – chock-full of GP drivers, Stuck and Chris Amon shared the winning 3303cc BMW 3.0 CSL from the similarly engined works car of Hezemans/Quester/Harald Menzel, then the 3498cc Alpina entry shared by Lauda/Hans-Peter Joisten.



Then it was off to Belgium for the classic 24 Hours of Spa Francorchamps.
There, Brian popped the car on the front row – sharing with German racer Joisten – between the works cars of Stuck/Amon and Hezemans/Quester.
Tragedy struck Joisten during the race when he passed two Alfa Romeo 2000 GTVs of Roger Dubos and Claude Ballot-Lena. Travelling too fast, Hans-Peter touched the barriers and was pinged back onto the track, where Dubos saw him and started to brake before being simultaneously rammed by Ballot-Lena, crashing into Joisten’s car. Both Joisten and Dubos were killed instantly in this freak accident.
Hezemans/Quester won from the factory Capri RS2600 of Mass/Fitzpatrick.
The next round was in the Dutch sand dunes at Zandvoort in mid-August. At the end of four hours the Zandvoort Trophy was held aloft by Hezemans and Quester who won from Muir and James Hunt in the Jagermeister Alpina entry. In third and fourth places were two RS2600 Capris led by the Fitzpatrick/Gerard Larrousse machine.



Three weeks later the ETCC circus raced at Le Castellet, contesting the 6 Hours of Paul Ricard.
With the RS2600 at the limit of homologated tricks – lookout for the 3.4-litre Cosworth GAA powered RS3100 in 1974 – the BMWs were again on the front row and finished in first to fourth places, a race of complete dominance.
Hezemans/Quester won from Ickx/Hunt, Stuck/Amon and Walter Brun/Cox Cocher. The best of the Capris – the Mass/Jackie Stewart machine – was fifth but 11 laps adrift of the winning car. Brian Muir and John Miles qualified eighth, but their 3.5-litre engine had head gasket failure after water loss.
The final round of the series was the RAC Tourist Trophy, it comprised two heats of two hours each at Silverstone on September 23.
The cat-among-the-pigeons was Gardner’s Camaro, although his speed was handicapped by tyre problems throughout. Harald Ertl’s Alpina CSL won the first heat from the Capris of Mass and Fitzpatrick with Muir a distant ninth having lost his front spoiler early in the race. Second place in the second heat behind Derek Bell’s Alpina machine was better; Brian was third overall behind Bell/Ertl and Mass’ Capri.
Toine Hezemans’ speed and consistency throughout the season paid off, he won the ETCC with 105 points from 42 years old Brian Muir on 77, and Dieter Quester on 75. BMW demolished Ford in the manufacturer’s title, 120 points to 97.

Note the ‘Nomex’ Polo-Shirt. Brian led the event late in its 50 laps but a pit stop to replace a tyre ruined his day, he was seventh in the race won by Pete Geoghegan’s Ford Cortina GT.
