In
1987 everything looked rosy for Lotus. The first prototypes of a new
smaller front-engined car, to be called Elan when launched, had gone
on the road, Group Lotus had made more than £2 million profit for General
Motors and a restyled Esprit was announced. The new style car, coded
X180 at Hethel, was launched in October 1987, with deliveries beginning
almost at once. Because this was merely a new bodyshell on an existing
and well proven chassis, with a new gearbox/transaxle, this was an excellent,
low investment way of developing a new model. The progress from concept
to production had taken only 15 months.
In
October 1987 Lotus dropped the original Giugiaro styled Esprit and replacing
it with a restyled car, designed by Peter Stevens. The new car was much
more rounded and every panel and piece of glass had been changed, yet
its overall profile was very similar indeed.
Compared
with the now obsolete and sharper edged Giugiaro style, the X180 was
more rounded, smoother and softer than before.
Compare
these two side on studies, and you should be able to pick one X180 styled
Esprit from the other, though the differences are small. The car above
is the Turbo version, complete with Esprit Turbo badges behind the doors,
while below is the normally aspirated model, which carries its Esprit
badges below the rear quarter window. Note the Lotus Design badge ahead
of the door pillars.
The
aerodynamic impression of shapes, incidentally, can be deceptive. Although
the new car looked much smoother than before, its drag coefficient was
in fact slightly higher, at 0.35 instead of 0.34. Cohn Spooners team
of designers, led by Peter Stevens, had solved a near impossible task
with great style. The aggressively sharp edged Giugiaro design which
had been truly in vogue in the Seventies but had been outdated by design
trends in the Eighties, was replaced by something more sensuous, more
gently rounded and more sophisticated yet it sat on the same backbone
chassis, with the same wheelbase and track dimensions. As with other
modem Lotuses, the new style was designed to be produced in two large
halves, top and bottom, mainly from glassfibre, but with some local
Kevlar reinforcement, using the companys patented vacuum-assisted resin
injection (VARI) process. The style was created in house, at Hethel.
Giorgetto Giugiaro, I understand, was not asked to offer ideas, and
probably never even saw the new shape until it was unveiled.

Two
more studies of the X180 Esprit. This is the normally aspirated model
(right), as introduced in the autumn of 1987, with what was know as
the open back body style between the two sail panels on the rear quarters.
While the 1988 model Esprit Turbo (left), which had a glass back feature
between the sail panels, and a different rear lower body moulding and
cooling grills arrangements. Although the profile of the new body varied
by no more than an inch from the old at any point, it looked very different.
All key lines were rounded off, rather than razor sharp, most details
such as the fuel-filler flap, and the air scoops for the engine bay,
which were in the sill mouldings ahead of the rear wheels, were much
tidier than before, front and rear bumpers were made in knock-resistant
mouldings, and, in spite of initial impressions, every single pane of
glass was a new shape and size. The new body featured a lift out panel
in the roof, this being either in a Nomex honeycomb material, or in
tinted glass.
There
were several basic visual differences between the normally aspirated
and the turbocharged types. Each car had its own special type of cast
alloy road wheel, though the same tyres were shared between types, while
the Turbos front end had extra driving lamps and a different front end
air intake. The biggest and most obvious difference was clear from the
three quarter rear aspect. Both types of car featured neatly detailed
flying buttress panels from the rear of the doors to the flip-up spoiler
on the tail, but only the turbocharged car filled in most of that recess
with a large sheet of glass to give what Lotus claimed was a tunnel
back feel. The Turbo also had a different rear lower body, with a carefully
profiled under tray/spoiler to act as a scoop to help extract hot air
from the engine bay and the brakes. Like the last versions of the Giugiaro-styled
Esprit of 1975 to 1987, the X180 Esprit had reclining seat backs. However,
as can be seen here, most of the time the seats would be pushed back
hard against the bulkhead, giving no scope for the backrests to be reclined.
Note the fixings for the glass roof panel. Inside the car there was
significantly more legroom and passenger space in general, but this
was still a small two-seater coupe cabin because there was a limit to
what Grand Prix designer John Cooper would call the Albert Hall effect
which could be achieved. Instruments and the panel were new, there was
a better ventilation system, which was sorely needed, as all hot climate
Esprit owners would no doubt agree, yet this was still not a car in
which tall, particularly well-built drivers could get comfortable.
The
X180 Esprit had a new type of instrument panel and facia, though the
general layout and features were familar. The footwell package was more
spacious than before, but all such improvements were relative, as it
still helped to have small feet and relatively short legs. Facelifts,
in general, do not always work very well, but the X180 process was in
any case much more than a mere facelift. It was a complete restatement
of the Lotus mid engined theme, and it worked out extremely well. The
designers had worked round the car in great detail, producing a neater
and more integrated solution to almost every task. The new car looked
so good that it was a temptation to go back to the old type, criticize
slots, flaps, lines and features and say to oneself: How could we ever
have put up with that? It was not heresy, but of how many other Giugiaro
designs would one even begin to be critical? Though little could be
done about the overall size of the two seater cockpit, particularly
as no changes had been made to the central backbone, or to the height
of the chassis pressings, the view from the drivers seat was little
different from before. There was a new and more integrated facia design
dominated by VDO instruments, the roof panel could be removed, though
surprisingly few owners seemed to take advantage of this feature and
improvements had been made to the ventilation system.
Mechanically
the new shape Esprits were very similar to those of the 1986 to 1987
HC models which had just been made obsolete, which is to say that for
normally aspirated cars the 172bhp engine was standardized, while for
the Turbo there were two different types, one with Dellorto carburettors,
the other with Bosch K Jetronic fuel injection. There was one major
exception, but only on non Federal market cars at first. Instead of
the familiar Citroen/Maserati type of five speed gearbox, Lotus had
to find a replacement that would fit, which was robust enough and suitably
packaged. Because the number of powerful European cars with combined
gearbox/final drive transaxles was increasing all the time, Lotus had
no trouble in finding a new supply. Links with Renault of France, which
had flourished in the Sixties in the case of the mid engined Europa,
were revived, and Lotus chose the robust Renault 25/Renault GTA type
of five-speeder instead of the old Citroen type. Surprisingly, though,
the Citroen gearbox was retained on USA market Esprit Turbo HCPIs for
the first year or so. The old Citroen gearbox had served Lotus well
and was still available from France, but all the mainstream Citroen!
Peugeot models which had used it had dropped out of production. Soon,
Lotus reasoned, the French company might want to close down supplies.
The 25/GTA-type gearbox, on the other hand, was relatively modern, and
had an assured future. This gearbox, incidentally, was a very versatile
unit. In the sporting GTA itself it was arranged to be ahead of the
final drive unit, and driving back to it. In the Renault 25, it was
behind the line of the final drive, and driving forward to it! For the
new Esprit, therefore, where the gearbox was behind the final drive,
there were strong similarities to the Renault 25 type of installation.
There was one other significant mechanical change, which was forced
upon Lotus. When Renault were developing the new gearbox, they had decided
to use outboard disc brakes on their cars. Accordingly, there was no
way that Lotuses inboard discs could be fixed to the new casing. The
old Esprit, therefore, had always used inboard disc brakes, fixed to
a Citroen transmission intended for such a fitting; the new car had
outboard discs for the very first time.
Clearly
the Esprit restyle had arrived at exactly the right moment. Backed by
the might of General Motors, Lotuses self confidence was glowing as
never before, and they had recently acquired control of the Lotus sales/distribution
organization in the USA. This was moved from New Jersey (west of New
York) to a brand-new facility at Atlanta, Georgia.The company was making
good profits, the still secret new Elan was on the way and sales shot
up. At the London Motorfair in October 1987 Lotus announced that they
had taken orders for 371 Esprit Turbos, worth £8.2 million. In 1987
a total of 462 Esprits, new type and old type combined, had been produced,
but helped along by the new style this total rose to no fewer than 1,058
in 1988, which was easily an Esprit record. In fact this was an all
time Esprit record, for although there would be another major new development
in 1989, Lotus never again built more than 1,000 Esprits in a year.In
the first half of 1988 UK sales totalled 271 cars, while exports rose
to 311, of which no fewer than 172 went to the USA. At the end of 1988
those figures had risen to 572 UK sales and 323 USA sales.
The
new style Turbo was a genuine 150mph car and this, allied to overall
fuel consumption of around 20mpg (Imperial), made the latest car an
intriguing proposition. Purists still complained about the restricted
cockpit space, the need for power assisted steering and the fact that
the car did not have ABS anti lock braking, but even they could drive
the Esprit faster than almost every other supercar, and still arrive
at the end of a trip with a big smile on their faces As Autocar testers
wrote in April 1988: The Esprit Turbo has many points in its favour.
Searing performance, a chassis and brakes to match and sensational looks
are only part of it. You also get acceptable fuel economy, a fine ride
with very little road noise and reasonable luggage space for a two seater
By supercar standards, the Esprit Turbo is something of a bargain.
