The return of Formula 5000s to Castle Combe will be one of the key attractions at the circuits’ Autumn Classic race meeting on Saturday.
During on-track demonstration sessions, at least three mighty Formula 5000 single-seaters from the early 1970s will run at the Wiltshire track, including the ex-Peter Gethin McLaren M10B, which won one of only two F5000 races held at Castle Combe in period.
Meanwhile, Grand Prix cars from Cooper, Lotus, BRM and Williams will tell the Formula 1 story from the late 1950s through to the end of the 1980s.
Examples of the Cooper T43/51 and Lotus 18 will be joined by two US-built Scarabs now raced by Julian Bronson and Eddie McGuire, an ex-Graham Hill BRM P261 from 1964, an ex-James Hunt Hesketh 308C and the Williams FW06 raced by Alan Jones to second place at Watkins Glen in 1978.
Taking the story up to the late 1980s is the Lotus type 101 chassis number 3 with a 600bhp normally-aspirated Judd V8 engine. The car, now owned by Steve Griffiths, was used by Nelson Piquet at the start of 1989 and then by Satoru Nakajima for the balance of the season.
The first European Formula 5000 Championship was held in 1969 when Peter Gethin was champion in his McLaren M10A. In May 1970, the thundering single-seaters arrived at Castle Combe for one of the most prestigious single-seater events in the circuit’s history.
The existing outright circuit lap record of 64.4s, set jointly in 1968 by Ron Fry (Ford GT40) and Jim Moore (Kincraft), was decimated when Gethin and Howden Ganley left the new mark at 56.6s, an average of over 117mph and a time that would stand for 14 years.
Formula 5000 returned to Castle Combe in 1971 when Frank Gardner won in his Lola T192 from the McLaren M18s of Gethin and Ganley. It was the last Formula 5000 race at Castle Combe as circuit owner Howard Strawford battled to keep the track open in the face of major noise issues.
The ex-Sid Taylor Racing McLaren M10B that Gethin raced in 1970, now owned by Martin Longmore, will be driven by Matthew Wurr in the parade laps along with two later F5000s. Neil Glover will drive the unique Chevron B37 built for the VDS team and raced by Gethin and Teddy Pilette in the US championship in 1976.
Nigel Greensall will drive a Lola T332, one of the most successful of Lola’s Formula 5000 designs. Greensall is the fastest man ever around Castle Combe as he lapped a Grand Prix Tyrrell 022 in 50.59s (130.93mph) in 1997, shortly before circuit alterations slowed average lap speeds.
The day’s racing programme covers an array of period cars including 500cc F3s, Formula Juniors, Jaguars, VSCC cars and the headlining GT and Sports Car Cup.
