The C5 built
In the spring of 1983, Hoover
Ltd at Merthyr Tydfil was approached by the Welsh Development Agency (WDA) to
see if they were interested in quoting for a project for Sinclair Research
"who are working on an electric car, and as a by-product of the research
have designed an electrically-assisted bicycle. They are looking for a
sub-contractor to whom they can entrust the assembly". It so happened that
Hoover had recently made a policy decision to look for sub-contract work,
although they did not think that they were in the bicycle manufacturing
business. However, when they heard that Sinclair envisaged sales of 200,000 a
year, rising to 500,000 a year, and that the fabrication techniques would match
their plant and experience, they naturally became very interested.
Of course, Barry Wills was
looking at possible manufacturers other than Hoover, but he was impressed at the
speed with which they reacted, and particularly when he saw the sketches which
Denis Roberts of Hoover had drawn of an assembly line for a product about which
he knew virtually nothing. Wills saw that he was dealing with people who could
understand what he needed very quickly - before he had told them even! - and
arrangements went ahead for drawing up an agreement. The WDA baulked when they
discovered that the plastic moulding could not be done in Wales, but eventually
an acceptable form of wording was found and Hoover at Merthyr Tydfil became the
manufacturing base for the C5.
One result of the leakage of
the Sinclair-Hoover negotiations:

Building C5s was not quite
what Hoover had envisaged when they were offering sub-contract facilities. They
had thought that perhaps they would be offering a specialist service, such as
porcelain enamelling, which was just one part of the process of producing a
washing machine. For the C5, they decided that they would have to set up a
separate part of the factory with its own quality control, goods inwards,
dispatch, and so on. In April 1984, half a dozen people were chosen from the
main factory, sworn to secrecy, and set on to manufacturing C5 parts. By the
time that original team had outgrown its sealed room, Hoover had set up a proper
assembly facility on the other side of the main Cardiff - Merthyr road, linked
to the main factory by means of an (existing) underground tunnel. Hoover
building MP7 was equipped with security locks and installation of the production
line began. Altogether, Hoover spent something of the order of £100,000
providing the facility.
Goods are delivered to a
roller shutter door, inspected, and stored for use in the various stages of
production. Almic of High Wycombe built the body welding equipment; the
polypropylene shell is dropped on to a jig and the welding tape tacked into
place with a telesonic gun. The main body is dropped over the top and clamped in
position by means of an inflated band. Current passes through the tape and fuses
the parts together; the jig is opened and the body taken out and hung on a
conveyor track. The whole process takes about 70 seconds. At another point the
assembly of the rolling chassis begins; tyres (from Taiwan) are fitted to rims
(from Italy), axles are assembled, with bearings pressed on and fitted to the
main chassis yoke; the steering assembly is fitted, and gradually the rolling
chassis is built up. Meanwhile, the accessories such as lamps are fitted to the
body shell, the wiring harness added; and soon body meets chassis for the first
time to form a complete C5.
When the vehicle is complete,
it moves along the conveyor on to the rolling-road test stand, which puts it
through its paces and either passes it for finishing and dispatch, or draws
attention to any faults there may be. The rolling-road test stand was developed
at Hoover and, like a lot of the other C5 test equipment, was manufactured by
Dancol of Feltham. The vehicle sits on the rolling road, an arm simulates the
weight of a 12-stone person, and the brakes of the vehicle are tested under
load. Each vehicle has its own manufacturing log going through with it. Hoover
had already developed an advanced testing arrangement for washing machines which
gives a computer print-out on machine performance, and the plan was to interface
the rolling-road tester to the in-house Hoover computer.
Finished C5s are rolled into
cardboard boxes on the conveyor belt which terminates in a special stacking
mechanism so they can be loaded straight on to the distribution lorries, stacked
three high, three wide, and six deep. Both packaging and the stacking conveyor
were designed and built locally.
There is little provision for
storage in the factory; the idea is that C5 packs are loaded straight into the
distribution lorries, which leave the site when they are full and travel to one
of the three distribution centres; Hayes, Preston or Oxford. The plan was that
there should be a stockpile of vehicles in time for the launch so that delivery
could be made well within the statutory 28 days.
In the autumn of 1984, Hoover
started assembling, disassembling, and reassembling 100 C5s, both to find out
what snags there would be in the process and to train the operators who would do the
work. Two production lines were installed, each of which could produce 50
vehicles an hour. At the outset, there was no plan to work shifts, but by
bringing both lines into play, and introducing shifts as necessary, up to 8,000
C5s could be produced every week.
It was a tremendous testimony
to the integrity of everyone involved with the development of the C5 - and the
sub-contractors and suppliers ran into hundreds - that the press was unable to
get hold of anything like a true story concerning it. The Engineer published some inspired guesses but, having presumably
overlooked the fact that the C5 might have been built to the
electrically-assisted pedal cycle regulations, multiplied its top speed by
three. A non-professional (and, if it comes to it, an unprofessional)
photographer produced a hazy photograph which was published in the Mail
on Sunday in October 1984, but it was incredible that anyone who had managed
to take a photograph of a vehicle - even a photographer that bad - could have
got the accompanying story so wrong: could it, in fact, have been a sop to his
conscience that the photograph was so poor and the detail so inaccurate?
Following that publication, Sinclair Vehicles sent a letter to all contractors
and suppliers who were in the know, assuring them that it had not been one of
the "planned leaks" for which the motor industry is known.
It is 10 January 1985; the
snow on the ground is beginning to thaw as I trudge up the hill from Alexandra
Palace station to the hall where the launch is to take place. While it is a
relatively still and quiet winter's day outside, the hall is buzzing with
activity inside: people milling around collecting press packs from girls dressed
in grey with touches of yellow, the theme colours of the occasion; many of the
men are wearing pullovers in shades of grey and yellow as well. We troop into
the arena, and take our places on tiered seating which puts me in mind a
dolphinarium. Even as we sit there, hardened journalists are subbing their press
handouts. Sinclair Vehicles and Sinclair Research staff are moving about
nervously; the atmosphere is awash with adrenalin.
Clive Sinclair speaks:
"Good morning ladies and gentlemen; thank you very much for coming to this
press conference today. It is of course a world first - the world's first press
conference held in a plastic bag... I'm going to start in a rather unusual
fashion by telling you what we are not announcing today, because there have been
some fairly confusing leaks. We are not announcing a conventional car. Sinclair
Vehicles Ltd is dedicated to the development and production of a full range of
electric cars, but today we have an electric vehicle, the first stage on the
road to the electric car... There have been several reports that the vehicle is
made of fibreglass; in fact it's not: the body is the world's largest, mass-produced injection moulding. It's astonishingly light, and astonishingly strong,
moulded in the ICI wonder plastic polypropylene which has absolutely marvellous
properties for a vehicle... enormously tough, enormously durable, obviously
completely free from rust. The pigmentation is in the material itself, so no
matter how scraped or scratched or bumped it gets it's never going to lose its
colour, never going to deteriorate... Another fallacy is that the vehicle is
powered by a washing machine motor. True, the Italian company that makes these
motors does make washing machine motors - but they also make torpedo motors.
This lightweight, highly efficient motor is specially developed for our
vehicle... Another (very understandable) fallacy is that on a low-speed vehicle,
wind resistance doesn't matter... the truth is that if you're designing a
vehicle efficiently - and of course we are concerned with the ultimate in
efficiency - wind resistance matters an enormous amount. A cyclist travelling at
20 mph is using 90% of his energy overcoming wind resistance. The reason people
have come to the conclusion that it doesn't matter up to 30 mph in a car is that
cars have such appalling road resistance. But the C5 doesn't; we've gone to
tremendous lengths to get the road resistance very low, and having achieved that
on an ordinary flat road, the wind resistance became dominant so we put a great
deal of effort into achieving a very low drag factor... Almost everything has
been designed and tooled from scratch for us - the lights, batteries, motors,
electronic control system. Because of our work at Sinclair Research, the
electronic control system is very advanced and we have a custom chip that
monitors everything and controls everything - get into the vehicle and you don't
have to think about it; it's all done for you...
We were very concerned right
from the start with safety. For that reason we asked the Department of Transport
who we should talk to and brought in all the best advice we could. We've gone to
great lengths to make the vehicle very visible both in daylight and at night,
and to make it tough. We're very much of the view that by encouraging people to
be on three wheels rather than two we will be adding considerably to safety on
Now, before I hand over to the
managing director of Sinclair Vehicles, Barrie Wills, I'd just like to introduce
the vehicles to you."
Music which is deemed suitable
for such occasions blares out. Further down the arena are six cardboard boxes in
which something appears to be happening. The fronts of the boxes are covered with
translucent paper, and six lights come-on; then six C5s burst through, driven by
six grey and yellow girls. They drive right round the arena and line up
side-by-side on the finishing mark. It is a solemn moment.
Barrie Wills recounts his
introduction to Clive Sinclair, his initial scepticism, and how he was won over
to the electric vehicle.
Wills went on to explain the
constitution of Sinclair Vehicles "similar to Sinclair Research, a small,
high-calibre team of people, principally product development and marketing
oriented with a very heavy dependence on the resources and expertise of
"We're developing a
family of traffic-compatible, quiet, economic and pollution-free vehicles for
the end of the Nineties. You're seeing the baby of the family today, the C5, a
completely new form of practical personal transport designed to meet the new
legislation for electrically-assisted cycles." Wills outlined the
legislation as it applied to the development of the C5. "Using a package
that was designed around the seating position of a Ford Capri, we developed it
for production, laying down standards well in excess of the legislative
requirement, imposing upon ourselves a system of testing based upon the United
States automotive self-certification patent."
Then came a video film which
took us through the development, testing and manufacture of C5s. "The
Prescott hill climb circuit was used to test both hill climbing performance and
brake descent. Parts of the track were flooded and many of the tests were
conducted in sleet and snow." Just like the weather outside that day.
"Accessories to make the C5 an all-weather vehicle have been designed and
are seen here... Waterproof side screens fit on front and rear wheel arches and
are attached to the body shell by Velcro. The protective cape and hood is also
attached by Velcro at the front and sides of the vehicles. Subsequent to this
stage, a fashion designer has developed the cape principle into an attractive
weathercheater, which is a cross between a ski jacket and a mountaineering
anorak. This includes a clever form of apron which encloses the cockpit area
while allowing freedom of arm movement for signalling."
Back to Barry Wills "...
The last thing we needed to produce C5 was a vehicle manufacturer. The
manufacture and assembly is far closer to that of a domestic appliance than it
is to a vehicle, and after a very exhaustive review, we chose Hoover's Merthyr
Tydfil plant for the assembly. They have put together a dedicated assembly
facility which was progressively equipped, manned and commissioned during
1984." He showed slides of the facility. "... Since 1 November 1984,
an excess of 2000 - and the count at 10.30 this morning was 2507 - saleable
vehicles have been built in preparation for the market launch today. We expect
to produce in excess of 100,000 units in 1985, creating some 200 new jobs at
Warwick and at Merthyr Tydfil.
"The C5 is the subject of
a massive three-month, £3M mail-order launch advertising campaign under the
theme of "A new power in personal transport". The first press
advertising will appear tomorrow, and the first TV commercial tonight. We going
to show you that TV commercial now."
Intimate, persuasive voice:
"Imagine a vehicle that can drive you five miles for a penny; a vehicle
that needs no petrol, just a battery; and that takes the press of a button to
start, the squeeze of a lever to stop. That needs no licence, no road tax, and
you can drive it whether you're 14 or 40. A vehicle that costs just £399. The
Sinclair C5 is a new power in personal transport. The Sinclair C5. £399. Want
to buy one? Want to see one? Or simply want to read all about it? Just dial 100
and ask for Freephone C5 - now."
Barrie Wills continues:
"Mail-order maximises initial quality awareness through the reinvestment of
higher sales margins directly into advertising. This provides the best possible
platform for retail introduction, which we anticipate in the UK before the
summer using retail chains such as white goods stores, supermarkets,
do-it-yourself stores, and department stores. Our marketing plans are made
possible by a series of major innovations in the after-market. These dispense
with the need for a conventional car dealer and service workshop infrastructure.
C5 servicing is franchised to Hoover: 19 Hoover service offices nationwide,
employing over 400 service engineers, have been equipped to undertake vehicle
maintenance on a door-to-door basis. 300 Sinclair battery centres have been
established using Comet Group stores and service shops and selected Woolworth
stores. These are already equipped to provide initial and replacement batteries,
installation kits and additional battery chargers, and to handle any customer
warranty problems on behalf of the battery manufacturer, Oldham. During the
mail-order phase, door-to-door delivery is being handled by United Parcels from
three strategically located warehouses... C5
heralds a revolution in personal transport. We need now to pay tribute to all
those who have contributed to making it all possible: Lotus Cars, Hoover plc,
Oldham Batteries, Woolworth, ICI, the 80 suppliers of components, the suppliers
of services and equipment, the Electricity Council, the Welsh Office, the
Department of Transport, British Aerospace, Motor Industries Research Association,
the Transport and Road Research Laboratory, the Royal Society for the Prevention
of Accidents and the UK Safety Organisation, and the University of Warwick.
Above all my team at Sinclair Vehicles - the best team of people I've ever
worked with. Together, we are also a new power in personal transport. Thank
This official photograph shows that the driver of a C5 is higher up than the driver of a Mini. Unofficially, the driver of the C5 is its stylist, Guy Desbarats, and the Mini is a cardboard cutout.
There is going to be a chance
to drive the vehicles later, but now it's question-time: the first question from
The Times: "Can you tell me where
I can buy one now; where is it on sale?" A benign opening question which
sets the pattern for a generally friendly session - just like the QL. We
disperse. Some people start to queue for their turn on the C5; others take a
stroll round the sideshows - C5 Driver magazines, C5 Driver hats, C5 Driver
pullovers, a C5 video-game, C5 mugs, C5 bags, C5 carrier bags, C5 caps, C5
duster, key-rings, sun visors, badges, T-shirts; the specially developed
garments. I queue up with Bill Sinclair for a ride on the C5; we're allowed one
circuit of the arena, and compare notes, exhilarated and excited. Then the
moment the lens boys have been waiting for: Clive Sinclair climbs into a C5 and
press photographers crowd round. How will the press receive this? I pick someone
at random: "Have we seen history being made today?"
"Yes, but not in the way
that Sinclair hope for. It's a shame that this vehicle could destroy credibility
for the future when Sinclair comes up with real vehicles. They're so keen to
come up with something, that they've had to come up with something that people
really weren't expecting. And a lot of people are going to view it, I think, as
a toy rather than a serious vehicle to use on the road. And I'm worried about
the road safety aspect, and I think a lot of other people are."
"But isn't this to
introduce people to electric vehicles at an amazing low-price - just as the ZX80
opened the market for home computing?"
"Yes, I think that's
probably the idea, but the ZX80 wasn't playing with lives. This is a gamble,
you're playing with lives - young people out on the roads."
"That's true, but surely
an enormous amount of thought has been given to safety?"
"Obviously a lot of
thought had to go into the safety aspect, but I still think that is still too
great a risk to allow 14-year-olds on the roads in one of these - I've got a 14-year-old son... imagine trying to cross lanes on a dual carriageway to turn
Can it be that the new
legislation has sown the seeds of the downfall of the C5? Would you let your 14
year-old out on the main road in one of these? Anyone who has suffered the
nightly truamata of the 16 year-old out on the moped will know the answer.
marvellous little vehicles - though I've yet actually to see one..."
Seldom has has a new product received such a wealth of attention from the cartoonists.
Was launching the C5 in the
bleak midwinter a calculated (or miscalculated) risk? The timing was such that
production was under way, and the launch could hardly have been held up until
the possibility of a bright spring day. Details were beginning to leak out to
the press, and from that point of view it was right that the official story
should be released as soon as possible lest the erroneous speculation should
have done more harm than good.
And although Sinclair Research
and the home computer market was quite separate from Sinclair Vehicles and the
C5 market, the two did meet in Clive Sinclair, who knew that success with the C5
would reflect well on the home computer market which was beginning to run into
Some said that Sinclair was at
the peak of his success and the press was looking for an opportunity to degrade
him. Some might, but generally I do not think that is a fair assessment,
especially with hindsight. The C5 was welcomed in some quarters - on the cycle
tracks of Stevenage, at Lowestoft, by the GLC: County Hall's chief traffic
engineer Ken Huddart called it a positive step forward in road safety. There was
some neutral reaction; in the House of Commons, Parliamentary Under Secretary of
State for Transport Lynda Chalker averred that the C5 was "no more
dangerous than a pedal cycle". One or two people who had lost their driving
licences through a passion for alcohol made news by purchasing C5s so that they
could once more become mobile menaces. In Glasgow, Stella Small said that since
1981 she had been successfully running a milk float which she had bought
second-hand from the Co-op.
"Of course I was riding on
the pavement, oshifer! I don't think I'd have been safe on the main road, do
Ron McTrusty at it again.
The vehicle was deliberately
launched as the C5 in the hope and expectation that the public would find a name
for it. As it was, names such as Doodle-Buggie, Hoover Hedgehog, Skinny Mini and
a Voltswagen came and (mercifully) went. But generally, the reaction was
adverse. The C5 was "rapped" (as the journalists say) by insurance
chiefs, road safety officers, and coroners. Dr Paul Knapman, Westminster
coroner, predicted that one day a C5 driver would die in a crash. "It's
just a matter of time" he said. In those independent isles, Man and
Guernsey, the C5 was to be treated as a car - which effectively ruled out its
use as it stood since it had neither speedometer nor horn.
Industrial unrest precluded
the visit of the Prince and Princess of Wales to the Hoover C5 factory scheduled
for 29 January. What this might or might not have done for the vehicle is worth
another pause for thought. At about the same time, it was announced that plans
for starting up the second C5 production line had been delayed, although sales
in excess of 5000 vehicles were claimed for the first month after launch.
At the beginning, Sinclair was
inclined to blame James Tye of the British Safety Council for the adverse
reaction; Tye had publicly stated that the launch should be called off, because
the BSC was unhappy with the safety of the C5. To be fair, he had said:
"Bear in mind, it is a well-designed thing for what it is"; it was
just that his eyes had been among the first to lose their scales. The other side
of the safety coin was that RoSPA (the Royal Society for the Prevention of
Accidents) had helped to compile a C5 safety booklet, which was handed out
freely at the launch.
All this was to no avail. The
C5 had massive publicity, and had it been able to stand on its own merits, it
doubtless would have done, whatever the critics said. As it was, that seductive
exhilaration which won everyone over to the C5 on the test track quickly
evaporated by the feeling of vulnerability among real traffic. A cost-cutting
exercise to get the price down to the magical £399 (which in any case was
pushed up to £428 when the delivery charge was taken into account) should not
have been achieved at the expense of a single accessory such as the high level
plug-in reflector bar. For whatever reason, all those vehicles which were tried
by the press - naturally out to test reliability and safety to the very limits -
should never have failed.
Those who know what a tremendous amount of development work went into the C5 to make it reliable and safe cannot help but be saddened that the end product did not appear to carry those marks of Sinclair's £7M investment.

When I submitted these texts to Rodney Dale for proof reading, his letter in reply included these two interesting fragments, reproduced with permission:
"What doesn't seem to come over is the sudden feeling of exhilaration being deflated. I rode/drove a prototype C5 round Lotus's yard - skips of scrap metal etc. towered above me, a couple of huge lorries were manoevering to deliver whatever they had. And yet I felt no feeling of danger, or lack of safety. Many other people had tried the C5 and felt the same. But at Ally Pally, it suddenly dawned on everyone at about the same moment that it wasn't so safe after all. A 5-foot pole with a fluorescent flag would have worked wonders."
"I remember another story about testing the C5 on the road - to maintain secrecy, this was done on the day of Prince Charles's wedding, as everyone was indoors glued to the telly."
