Coming
under the aegis of General Motors has created a different mood at
Lotus. The liason has opened doors to the Norfolk-based specialist
sports car maker that enable it to continue doing what it is best
at, but doing it now safe in the knowledge that GM is a guarantor
should Lotus need access to financial resources for advanced work.
Previously Lotus often found themselves with the expertise but without
the all important purse strings.
With
this new found confidence in the future, a mere 18 months was all
it took the company's in house design team to design a replacement
for the once stunningly futuristic but now unfashionably angular
Giugiaro penned wedge that we first saw in 1976.
The
new Lotus Esprit Turbo has found the soft, rounded lines that flow
in a harmonious composition with air intakes that are part of the
organism rather than an afterthought – unlike some of it's
competitors. Yet this accomplishment produces no trace of sacrifice
in the rakishness of a car that has to look as it is moving when
it is at rest. Intensive wind-tunnel work has produced a vehicle
that is at once more stable at speed and yet more slippery. The
Turbo cleaves the air with a 0.33Cd while it's naturally aspirated
counterpart is under 10 per cent worst off. An interesting feature
of the Turbo's design is the glass panel that sits astride the rear
buttresses, but stops short of the rear deck. This device is partly
responsible for the improved aerodynamics and also improves the
visual integrity of the car when viewed from certain angles.

The
fitting of such a panel would be tempt fate in a body-shell subject
to much flexing, so it is a tribute to the rigidity of the new shell
that no such problems exist. The old Esprit was made from hand-laid
GRP, the new car followed the Lotus patented VARI (vacuum assisted
resin injection) route like the Excel and picks up the speed, quality
and stiffness in the process. The mechanical underpinnings are much
the same, but the spring and damper rates of the double wishbone
coil sprung independent suspension have been altered and the rear
disc brakes moved out board. Lighter alloy wheels more than make
up for an on-paper increase in un-sprung weight.
The
four cylinder all-alloy 16 valve engine remains unchanged save for
the use of a water-cooled turbocharger with integral wastegate.
Power is up by 5bhp to 215bhp at 6,250rpm with 220lb/ft of torque
at 4,200rpm. The twin carburettored Esprit is good for 172bhp at
6,250 rpm and 163 lb/ft of torque at 5,000 rpm which gives the car
a claimed top speed of 138mph and 0-60 of 6.5 seconds. The Turbo
adds 14mph to the top speed while cutting 1.2 seconds off the acceleration
benchmark.
The
original Esprit was a tight fit for anyone who dared aspire to tallness
and if height could be a problem, then so could girth. All that
has changed, and an all new more roomy and yet cosy interior that
is at once more modern, more ergonomic and easier to see out of
greets the lucky driver and passenger. The very tall still have
a problem, but for the majority, the car is close to perfect. The
revised dashboard now reveals its information more easily and the
general fit and finish of the hide and carpet is pleasing as it
should be on a low volume production car costing £22,950 without
Turbo, £28,900 with.
The
new Esprit and Esprit Turbo have taken the essence of the original
and honed it to a fine point. The car now has a blend of qualities
that like a good wine is mature, synergetic and in balance. That
balance brings to mind a lesson that the late Colin Chapman, founder
of Lotus Cars, was taught in engineering school. "It is easy
to make a bridge stand; it is difficult to make it just stand."
