I took this photograph at the Donington Park Museum in March 1996 showing the rear end of the car that brought BRM its only World Drivers' and Constructors' Championships.
It's the 1962 BRM P578 which Graham Hill drove in the 1962 and 1963 seasons, although the 'stack-pipe' exhaust system was quickly revised as the pipes had a tendency to drop off quite frequently. The Great Racing Cars of the Donington Collection says this about the car:
'The ‘Stack-Pipe’
BRM’s
Championship winner
Sir Alfred Owen made it clear to BRM’s
personnel that 1962 was to be their make-or-break season. They had won their
first, and so far only, Grand Prix victory at Zandvoort in 1959, and now the
expensive new 1½ litre V8 engine had to prove itself successful. It did, and
Graham Hill won his first Grand Prix at Zandvoort, went on to win again in the
German, Italian and South African rounds, and ended the season as World
Champion Driver. British Racing Motors won the World Constructors’
Championship; honour was satisfied, and the concern survived. BRM’s prototype
P56 V8-engined car appeared in practice
for the 1961 Italian Grand Prix at Monza, where it impressed as one of the
sleekest and smallest Formula 1 cars of its time. The engine was a 90-degree
twin-overhead camshaft V8 with Lucas fuel injection, designed by Chief Engineer
Tony Rudd, and initially it offered about 188bhp at 10,500rpm. The prototype
P56 car introduced a neat and light multi-tubular spaceframe chassis with
strikingly handsome bodywork, and the type began the 1962 season with
individual megaphone exhausts swept-up from each cylinder bank. These won it
the name of the ‘Stack-Pipe BRM’, and Hill won the first heat of the Brussels
GP with it, then went on to win at Goodwood and then in an epic near dead-heat
with Jim Clark’s Lotus-Climax at Silverstone. The stack-pipe exhausts regularly
came adrift, and were replaced by a complex low-level system at Spa. Hill fought
a season-long battle with Clark, and his American team-mate Richie Ginther
drove ably to take third place in Germany and second to Hill in BRM’s great day
at Monza. BRM V8 engines sold well to private customers, and the P56s raced on
through 1963 when Hill won the Monaco and United States GPs and Ginther
excelled once more. The pair chased Clark home in the World Championship table.
By that time, people had stopped laughing at BRM!'
The car was generally known as the P578 to differentiate the 8-cylinder car from the previous season's 4-cylinder P57, but because it had a P56 engine the car itself was known as such by BRM.
