The Rochdale Olympic Phase I & II
The Olympic represented a huge step forward from anything Rochdale
Motor Panels had built before, and its existence is largely down to
one man: Richard Parker. His first contact with Rochdale was in 1955
when he was purchasing some glassfibre to make a special body for an
Austin Seven; later he became involved in creating the GT. While he
was waiting to take up a postgraduate apprenticeship at the Bristol
Aircraft Company, he was asked to join the company. At this time
Rochdale was still building the GT and there were many discussions
on the way the market was heading and what kind of car they should
develop next. Pooling their skills, Parker's Engineering degree and
Smith and Butterworth's knowledge of manufacture of their earlier
bodies, they realized that they could build a bodyshell strong enough
to do without a chassis frame. Simple sketches were drawn of the
car's proposed styling and then photos were taken from different
parts of cars that the team found appealing. A fundamental
requirement of the design was that it should be aerodynamic, to
gain the best performance from whatever engine was used.
At the time Richard's father had an early Porsche and this had a
significant influence on the final shape of the Olympic, though
styling cues can also be seen from the GT and Riviera models. With
the basic styling agreed, plaster shapes were made, sections being
scrapped or modified until the definitive Olympic design emerged.
Meanwhile Richard had joined Bristol where he would remain until
Smith asked him to join Rochdale permanently.
When Richard returned, RMP had almost completed the mould for the
first prototype. The prototype body was laid up and work began on
constructing the car. It had been agreed to use components from the
Morris Minor (solid rear axle, torsion bars at the front and a
BMC A-series power train) as they were simple, strong, cheap and
readily available. The prototype tested at over 85mph despite its
meagre engine power, illustrating the aerodynamic qualities of the
body.
Development on the prototype continued well into 1960 with the car
covering 30,000 miles, during which time details were finalised for
the production version and another mould was prepared, incorporating
larger windows and a purpose made, highly curved windscreen. The
success of the Riley 1.5, using Morris Minor-derived running gear,
led to a swift switch that gave the Olympic 105mph performance.
Most production cars had the Riley 1.5 engine, though Minor, MGA,
Ford 100E and 105E were also fitted and one left the factory with a
Coventry Climax racing engine.
Road testers raved about the Olympic. In a first test of the
well-used prototype, The Motor wrote: "Driving the prototype
emphasised the rigidity of the construction, none of the body shake
often found in glassfibre specials being evident. There was very
little wind noise and the top speed was commendably high." Full
road tests of the production Riley 1.5-powered car sold as a complete
kit of parts for £670 which it was claimed could be assembled in
48 hours but which, in fact, took many people 48 days or more were
equally positive. Performance figures of 0-60mph in 11.7 seconds and
102mph maximum (limited by gearing) were recorded with a 60bhp
engine which also gave fuel consumption of over 40mpg.
The Phase I took its front suspension from the Morris Minor or Riley
1.5: a torsion bar system with rack and pinion steering that was
regarded as one of the best around at the time. On the Rochdale, the
Minor's tie bars are replaced with an anti-roll bar, which provides
location as well as roll restraint. At the back end, the Minor's leaf
springs are rejected in favour of radius arms and telescopic
spring/damper units, which locate the back axle very effectively.
Handling is one of the Olympic's strongest points: its engine is
set well back so the weight distribution is excellent and cornering
is very neutral with little roll and good throttle control.
The front suspension, steering and engine mountings are carried on a
steel tubular subframe which is bonded to the inner wings and
floorpan, while the rear suspension and the gearbox mountings bolt
directly into the glassfibre body without any steel reinforcements.
High stress points were identified during the car's development and
extra layers of glassfibre used there, so that the body's thickness
varies throughout from around 2mm in areas like the centre of the
doorskin to 10mm or more where the radius arms bolt to the body. The
only other steel in the body is a roll hoop built into the windscreen
surround, which makes it strong enough to roll over several times
without damage to the glass just some crazing to the roof, as a few
owners have proved!
Rochdale's position in the forefront of Ford Special production ended
abruptly with a disastrous factory fire in February 1961, which
destroyed the building and all the moulds inside it. This terrible
setback came at a time when a great deal of money had been sunk into
the development of the Olympic, which had just received rave press
reviews. Rochdale was forced to abandon all the early models and
concentrate exclusively on getting the Olympic back into production.
It took months, during which many orders were lost.
The Rochdale team didn't rest on their laurels, introducing the
Phase II Olympic at the start of 1963 with a Ford Cortina 1500GT
engine and redesigned suspension all round, now Triumph-derived at
the front and incorporating disc brakes. There was an electric
cooling fan, windscreen washers were standard and the GRP thickness
was reduced, which reduced the body weight by 1cwt. A hatchback
made luggage access easier and performance from 78bhp was 0-60mph
in 11.2sec and a maximum of 115mph. The price for the new kit was
now £735, or the car could be purchased ready-assembled for
£930.
But behind the scenes, Frank and Harry were getting fed up with the
hassles of being car manufacturers, sourcing all the components,
and dealing with the inevitable customer complaints when they couldn't
fit the bits together (virtually all Olympics were sold as kits).
Richard Parker had been poached by Lotus and in retrospect, they had
priced the Olympic too low and couldn't afford to improve the
quality. They found a profitable sideline in making heating ducting,
which gradually turned into their primary business.
In all, some 250 Phase I and 150 Phase II cars were built, almost
all by 1967 though the car was theoretically still available in the
early 1970s. The last Olympic bodyshell was turned out (after a lot
of effort to persuade them to make it) in 1973 and a few years later
the moulds were sold to a group of Rochdale owners who still preserve
them.
