Reflections
on Bentley at Le Mans
by David Blumlein

'EXP
Speed 8' they chose to call it. Ah, it is that epithet 'Speed' which
forges the links with Bentley's illustrious past, an era in which
this relatively young marque became the supreme force in sports car
racing. There can be few genuine enthusiasts who did not feel some
tinge of delight that the famous name's reappearance at Le Mans this
year, especially in view of the fact that it did so unexpectedly well.
After all, was it not a 'speed' model that was responsible for the
firm's last two victories in the Sarthe?
This
happy episode naturally awakes an urge to look back and reflect on
some of the manifold achievements or, more specifically, on one particular
car, the first racing Speed Six, subsequently known as 'Old no. 1",
its race number on the occasion of its first Le Mans win.
This
six-cylinder version of the vintage Bentley has an unusual provenance:
it was created through necessity. The original 4-cylinder 3-litre
model had been launched as a sporting car but it was very much the
custom of the time, particularly among the more affluent in the twenties,
to purchase a chassis and have bespoke coachbuilt bodywork added to
one's taste. The 3-litre model fell victim to this trend rather more
than intended and it soon became clear to "W.O." that the
weight of all this bodywork was hampering the performance of the car.
Something more powerful was urgently needed.
Thus
came into being a 3-litre engine with two more cylinders giving a
capacity of some 4 3/4-litres. A major difference was that the camshaft
was now driven by a three-throw crank at the back of the block, reflecting
something of W.O.'s early experience with railways at Doncaster.

This
new motor was fitted to a prototype chassis clothed in rather clumsy
six-light saloon bodywork with a deliberately ugly radiator shell,
the car being passed off as a 'Sun' (although at this time there had
been some four different cars built from Berlin to America bearing
this name, the last such conveniently going out of business in 1924,
the year we are concerned with!). Bentley himself and colleagues used
the car on long continental test drives, the patron taking the opportunity
to include visits to the French Grand Prix at Lyon and the Le Mans
24-Hours for which he had become an ardent supporter and which that
year, of course, yielded the first of Bentley's five wins.
It
was on the return to Dieppe that the 'Sun' by chance came across the
prototype Rolls-Royce Phantom 1 equally on test and, as a result of
the 'race' the two cars had for a while, Bentley became convinced
of the need to increase the capacity of the 6-cylinder engine before
production got underway. Hence the 6.5-litre, designed to cope with
all that bodywork that the expanding Bentley clientele demanded.
The
firm's racing activities continued to revolve around the 3-litre and
its bigger cousin the 4.5-litre, the former bringing dramatic victory
at Le Mans in 1927, the latter in 1928.
In
the meantime the 6.5 was offered as a Speed Six, a twin-carburettor
version upgraded to give more performance. One of these (to become
the "Old No. 1") was given its race debut in the Double
Twelve race at Brooklands on 10-11 May 1929. This event served as
a useful curtain-raiser for Le Mans cars rather as the Silverstone
6-Hours/1,000 km came to be in the latter decades of the 20th century.

The
Speed Six sheared its dynamo drive but this was amazingly to be
its only retirement in its 'works' competition life through mechanical
failure!
The
car then led the 1,2,3,4, triumph of the marque at Le Mans that
year, Barnato and Birkin leading the 4.5-litres home. Later that
month this same car won the B.A.R.C. Brooklands Six-Hours race with
Barnato and Jack Dunfee, only to be crashed at Bradshaw's Brae by
the fearless Glen Kidson in August's T.T. on the Ards circuit.
Two
more Speed Six cars joined the works team for 1930, the competition
from Stutz and Mercedes calling for the bigger power of the six-cylinder
engine, but "Old No. 1" did its stuff again at Le Mans,
giving Barnato his hat-trick, sharing this time with Kidston. The
Clement-Watney car came second but Clive Dunfee crashed the third,
not being able to extract it from the sand at the modified Pontlieue
corner.
The
impending collapse of the company meant that this was the official
team's last appearance at Le Mans but Speed Six "Old No. 1"
had carved herself a special place in Le Mans history, shared only
by three post-war victors: the honour of winning twice in succession
with the same actual car (the others being the Ford GT40 P.1075
of 1968-69, the Joest Porsche 956 chassis 115 in 1984/85 and more
recently the TWR Porsche WSC001 in 1996-97).

For the history books, the Speed Six is chassis LB2332, index no.
MT3414.
And
so to our new Speed Bentley. The story is still fresh in our minds
and doesn't need repeating here but I finish with a couple of observations.
First, the car is not a 'warmed-up' version of the Audi R8C coupés
that failed at Le Mans because they had been commissioned far too
late to be developed in time. Secondly, the Speed 8 is the first car
to enter the LM-GTP category at Le Mans since 1999 when the aerial
activities of Mercedes seemed to frighten everyone off from the class;
it revives interestingly the debate about open or closed cars standing
the best chance of coping with twenty-four hours of hard motoring.
And
so, as the new decade unfolds, let us hope that the Speed 8 can at
least live up to the record of the Speed Six model, the best of the
vintage Bentleys and allegedly W.O's favourite.
