Sharp-edged wedges were the order of the day in the Seventies, when Giorgetto
Giugiaro’s original Lotus Esprit was unveiled as the Silver Car concept
at the Turin motor show in 1972. Based on a Europa twin-cam chassis, it
was developed to the point where the first Esprit prototype was displayed
at the 1973 Geneva salon.
It was another three years before the first customer cars were delivered,
and as was typical in the mid-Seventies, the customers were left to finish
the car’s development The Europa had never been regarded as a particularly
desirable car, having unattractive styling and poor interior packaging.
The Esprit had to address these issues, and that the concept still looks
fresh today (if a little passe in execution) is testament to the team that
produced it.
iugiaro had wanted to call the car Kiwi, but Lotus management was intent
on a name beginning with the letter E, as is Lotus tradition. A trawl through
the dictionary came up with Esprit, which it felt summed up the car’s
prightliness.
Even before the project had been properly instigated the choice of powerplant
was never in doubt, with Lotus hailing recently completed development of
its Type 907 twin-cam engine. Mounted ahead of the rear axle line, the unit
has become one of the all-time greats.
When the new car made its debut, Car magazine compared it with the Countach,
largely because of its dramatic, sharp edged styling. By then Lotus was
synonymous with fine-handling cars; and Car reckoned the Esprit’s
handling and performance were as sharp as its design.
In good condition the car can still hold its own against the current crop
of junior supercars — but you have to buy wisely. — Steve Williams
is based in Windsor — his company specialises in the servicing and
maintenance of all Lotuses and he’s our guide through the maze that
is buying a Giugiaro Esprit.
Body and chassis
Lotus’ pioneered a production method called Vacuum Assisted Resin
Injection (VARI) which created a particularly strong and durable glassfibre
shell. All its post-1975 cars use this technology, but the shells are heavy
considering their plastic construction.
The Esprit’s chassis is equally durable, but accident damage and rot
– which is mercifully rare – are not easy to repair. The only
proper solution is to fit a replacement chassis, (they are now galvanised).
The chassis itself is £1500, but add in replacement suspension bushes,
steering rack and brake pipes and the cost doubles. Getting a specialist
to replace it will add another grand or so.
All Esprits from the S2.2 onwards are fitted with a galvanised chassis,
and many built before then have since had one fitted. Steve comments: ‘If
you’re, looking at an S1 or S2 make sure the chassis hasn’t
corroded; the only way to check is to put the car on ramps. Between the
chassis and the bodyshell there’s an insulating layer of felt, which
absorbs water then corrodes the chassis. It’s not possible to check
the top of the chassis as it’s out of sight, but if you tap the metal
with a hammer you should hear a crisp clang. If you don’t it’s
likely the metal has started to dissolve.’
Body panels are also available — in fact. if you need a new shell
it’s possible to buy one. Because the shells are strong, the only
issue with these cars is poorly repaired accident damage. Any repairs should
be completely invisible, but cracks, splits and general unevenness all indicate
the work of a bodge artist.
While you’re inspecting the bodywork take a look at the nearside rear
wing. Loose cargo in the boot sometimes whacks the inside of the panel leading
to star-shaped cracks. The offside isn’t similarly afflicted because
the battery prevents anything from making contact with the wing.
The Esprit’s nose is prone to stone chips, but at least there’s
no resulting rust. More serious is stone damage to the bodywork —
if the panels are hit hard enough by flying debris, you’ll find those
star-shaped cracks again. The only way to fix this is to grind the, glassfibre
back and insert fresh matting, which is labour intensive if there’s
a big area to be treated.
Engine
There were three versions of the all-alloy Lotus twin-cam engine fitted
to the Esprit. The 2.0-litre is designated type 907, the 2.2-litre carries
the type 912 tag and the 2.2-litre turbo is known as the type 910. All the
engines will cover 100,000 miles quite happily between rebuilds as long
as 6000-mile service intervals have been adhered to.
Engines in the Turbo HC are much stronger, with an uprated cambelt, along
with stronger carriers, covers, pistons, liners and turbo. From here on,
the pistons and liners were of Nicasil-coated aluminium, which is more durable.
Because the oil pump is set high on the engine it takes a while to draw
the lubricant from the sump. So make sure an oil filter with an anti drain
valve has been fitted — if it hasn’t, the big-end noise that’s
inevitable for the first few seconds will be audible for much longer. Steve
warns: ‘Some owners try to economise by fitting a Ford oil filter,
which is half the price of a genuine lotus one, but with the real thing
weighing in at just £12 and the Ford one not being up to the job.
it’s a bit of a false economy.
Expect to see 35psi at 3500rpm once the engine is up to temperature, and
at tickover don’t be alarmed if there’s just 5psi showing on
the gauge. According to the handbook, there should be no less than 45psi
with the engine singing away at 6500rpm.
All Esprit engines should have their belts replaced at 24,000-mile intervals
or every two years, so check this has been done. Servicing should also have
been carried out every six months or 6000 miles.
The 907 engine often leaks oil from the cam carriers and covers. The oil
drips onto the exhaust manifold and gets burned off — don’t
just tighten the carriers or covers as damage will result from stripped
threads and distortion. Because of these leaks (often caused by cam cover
gasket failure) the engine may start to misfire, as the oil will collect
in the spark plug recesses.
The heating and cooling cycle combined with poor cooling suffered by the
exhaust manifold causes it to crack after a while. Make sure it’s
not blowing when cold, as replacement may not be straightforward. If you’re
buying a non-Turbo you might get away with just four hours to replace the
part, but a Turbo with problems requiring cylinder head removal could take
up to 12 hours. With official Lotus dealers charging up to £75 per
hour and a manifold costing anywhere between £300-400 and more, you
could quickly blow a large hole in your budget.
Says Steve: ‘Its also paramount that you keep an eye on the boost
pressure gauge when you give the car a test run. The wastegates are prone
to seizing, so as well as watching that the gauge peaks at 0.8bar, listen
out to ensure it’s operating properly You should be able to hear it
quite clearly.’
Cooling systems were a constant source of development because of overheating
problems. The low-slung radiator can leak (without it being obvious) and
head gasket failure or even warped cylinder heads are not unheard of.
All Esprit engines will run happily on super unleaded, as they are all fitted
with valve seat inserts. Steve recommends the addition of a lead substitute
to boost the octane rating and help prevent pinking.
Transmission
The rear suspension design of S1 and S2 models is such that the universal
joints and (Maxi front) wheel bearings don’t last long. Steve recommends
you ask if the correct hardy-Spicer items have been specified, as anything
else won’t last long. Look for evidence that the wheel bearings have
been greased regularly. Esprit S3s onwards have a much more durable design.
The five-speed gearbox is the same as that found in the Citroen SM. If the
spigot bearing hasn’t been greased it will fail, wrecking the crankshaft
in the process. There’s no way of checking this has been done without
removing the gearbox. but if the owner claims that the clutch has been replaced
recently, ask if the spigot bearing was replaced at the same time.
Steering and suspension
Steering racks on S3s and later wear more quickly than on earlier models,
as the wider wheels and tyres put a greater strain on it. Don’t expect
to see more than 48,000 miles out of a rack — a hard-driven car could
eat its rack in half that mileage and a new one will set you back £200,
along with the bill for replacement.
If the steering seems impossibly heavy it’s probably because the universal
joint on the steering column has seized, which will cost £20 to replace
(plus fitting).
The front suspension of post-1985 cars is Toyota-derived and reliable. Before
this date, the design was based on the Elan system, with trunnions that
needed regular oiling. Check the lower wishbones, which can crack near the
anti-roll bar mountings.
Brakes and wheels
Because there’s no method of lubricating the handbrake, it tends to
seize; it also tends to get kicked with monotonous regularity because the
lever is mourned on the sill. On S1 and S2 models, the mounting can break
away, but the introduction of the S3 brought with it a strengthened mounting.
S1s were fitted with Wolfrace alloy wheels, adding to the kit car look.
From the S2 onwards Esprits were fitted with Speedline wheels. Early S3s
featured BBS wheels, which are now very hard to source — fronts are
all but unobtainable.
The Esprit doesn't suffer the poor electrics that often plague glassfibre
cars,
but do check headlamp relays.

Electrics
Plastic cars often have unreliable electrics, but the Esprit doesn’t
suffer too badly. The window motors can seize because of corrosion and the
glovebox-mounted fusebox can lead to problems when the fuses get knocked
by luggage, but that’s about it.
It seems that once a car starts to suffer from electrical glitches it will
get progressively worse. So if there are things starting to go wrong, make
sure you’re aware of the extent of the problems. Headlamp relays are
worth checking, as these will be one of the first trouble-spots.

Interior trim
Various trim materials were used, including leather, cloth and Marquasite,
which is similar to crushed velvet. The leather trim (available as half
or full) tends to crack with age, especially on the driver’s seat.
Essex cars were fitted with air-conditioning, and the system is normally
pretty reliable – as long as it’s been look after.
Exterior trim
The bonded screens of S1 and S2 models were state of the art when new, but
they don’t age very well. Check if the screen has been resealed since
it came off the line — if it hasn’t, it’ll be due before
long. Resealing the screen costs £100 or so, but if the screen cracks
when it’s being removed (which is likely) the cost will quadruple.
Check the dash and footwells for deterioration because of water ingress.
Window frames for the side glass are powder-coated — but not very
well. Replacements are available but if caught in time the metal can be
refinished.
Spares
Panels are available and, as the shell is plastic, you won’t have
to worry about hidden rust. That’s not so with the chassis, but with
replacements available that’s another thing you don’t have to
worry about. The problems are with the smaller trim items, although there’s
still an amazing amount turning up at autojumbles and through the club.
Conclusion
Rolling restorations are easy with the Esprit — if the car you’re
looking at has poor paintwork you know the bodywork won’t deteriorate
while you’re saving your pennies. The secret, as ever, is to buy the
best you can afford and be choosy when looking. And don’t be tempted
to buy an S1 just because that’s what was in the Bond film —
later models are better screwed together.

WHICH IS WHICH?
The Esprit S1 first showed its face at the 1974 Paris salon, although promotion
problems prevented it from going on sale until June 1976. It was powered
by an in-house, 1973cc, aluminium engine developing 160bhp. This was bolted
directly to the chassis (so the driveshaft could act as a suspension arm),
leading to poor levels of refinement — just 744 were built.
The S2 debuted in June 1978, featuring an improved interior, Speedline wheels
and SD1 taillights — 1,060 were produced. Power remained at 160bhp
and, to commemorate Mario Andretti becoming F1 World Champion, 147 JPS black
and gold special editions were built.
In February 1980, the engine was stroked to 2174cc and the Esprit became
the S2.2. From here on a galvanised chassis was standard, but only 88 S2s
were made. The Turbo Esprit was launched in February 1980, as the Essex.
With 210 bhp it cost nearly £20,000 — 100 were planned but just
57 were made. With proper rear suspension, the car was much smoother and
quieter. Spilt-rim Compomotive alloy wheels were fitted.
In April 1981, the normally aspirated Esprit became the S3, with the same
chassis and suspension as the Turbo for greater refinement; 767 rolled off
the line. At the same time, the Turbo became a regular production model
with a reduced trim specification and a price reduction to £16,928.
Dry-sump lubrication was a feature until 1983 — a carry-over from
the Essex. 1,658 were produced. The final version of the Giugaro-designed
Esprit surfaced in 1986: the 215bhp Turbo HC, standing for High Compression.
A year later Peter Stevens’ restyled Esprit went on sale.
HOW MUCH?
Unless you’re looking for a project car (and make sure that’s
what you really want) you’re going to have to find at least £4000
to buy an Esprit. For That money it won’t be ready to show –
or perhaps even use if it’s later than an S2. Buying an S1 may seem
very romantic if you’ve just been watching James Bond, but the cars
were troublesome then and they’re no easier to Iive with now.
Club Lotus
member Trevor Cook bought his 1976 Esprit S1 two years ago, having searched
the UK and Ireland for a good one.
His first Lotus (Trevor had wanted an Esprit S1 since seeing one in The
Spy Who Loved Me) had to be a series 1, which are increasingly difficult
to source in good condition. With just 744 made, and most of those exported,
there aren’t many decent ones from which to choose. In the end the
yellow S1 pictured was bought, with just 20,600 miles recorded, which he
found just a few minutes from his Middlesex home.
A previous owner had Lotus dealer network connections, and even better,
the car had been stored for nearly 12 years along with bits that are hard
to source — things like rolls of the interior trim used for the seats
and dash top. Although a full interior restoration isn’t needed yet,
it’s reassuring to know such items — which normally scupper
the concours restorer — are to hand.
Apart from fettling the cooling system, the car hasn’t needed much
work. Trevor reckons there’s a bit of detailing to be done on the
fascia to make it truly outstanding and once that’s done he hopes
to use it for local club meetings.
Although his car is irreplaceable, Trevor is no longer convinced that the
S1 is the model to go for: ‘The design and build of the S1 is abysmal.
Nothing fits, whereas on the subsequent cars things were generally sorted.
I wouldn’t recommend an S1 to anyone unless they know what they’re
taking on — but there’s no way I would be parted from mine.’
