The Lotus Esprit is a rear mid-engine, rear-wheel-drive sports car built by Lotus Cars at their Hethel, England factory, from 1976 to 2004. Together with the Lotus Elise / Exige, it is one of Lotus' most long-lived models.
The Esprit was among the first of the (near) straight-lined, hard-edge creased, and sometimes wedge-shaped, polygonal "folded paper" designs of the prolific, and highly successful Italian industrial and automotive designer Giorgetto Giugiaro. The Esprit's backbone chassis was later adapted to carry the body of the DeLorean car, another low-bodied, Giugiaro-drawn, sharp-creased, wedge-shaped sportscar design. In 1978, the first updates led to the series 2 and engined Esprit S2.2, made until the 1982–1988 Series 3 and Turbo Esprit models, that used a 1980 Giugiaro designed aerodynamic and aesthetic restyling package.
The Lotus Esprit however, lived on through the 1990s, and into the 2000s. It received its first significant restyling by designer Peter Stevens, who also did styling on the McLaren F1. Stevens gave the Esprit overall softer lines and shapes, but the car did not get a new series number – it is instead often just called the 'Stevens Esprit', or by its project number, the X180, made from 1988 to 1994.
In 1994, an official Series 4 Esprit, drawn by designer Julian Thomson, had a further rounded shape, especially the bumper sections and lower body of the car. Styling-wise, this became the most long-lived Esprit (1994–2004), only receiving its last changes, by Russell Carr in 2002.
Over the years, the performance of the Esprit's 4-cylinder engine was increased from around and just under of torque, to double those power figures, mainly through greater inlet and exhaust flow, and strong turbo-charging. And from 1996, a new V8 twin-turbo engine was added, offering . Contrary to a long list of low-volume British (sports) cars, with the 3.5 l Rover V8 engine, the Esprit received a Lotus in-house designed V8. Top speed rose from some in 1976, to over for the V8, twenty years later.
After a 28-year production run, the Esprit was one of the last cars made with pop-up headlights, together with the 5th generation Chevrolet Corvette.
Background
In 1970 Tony Rudd, who had started at Lotus the previous year, proposed two new model development projects. The first, Project M50, resulted in the 1974 Elite. The second, Project M70, meant to develop a successor to the Europa which, like the Europa, was to be a two-door fixed-head mid-engine coupé.
A meeting between Colin Chapman and Giugiaro was arranged in 1971 by designer Oliver Winterbottom, who also suggested that Giugiaro use his Maserati Boomerang concept as the inspiration for the new Lotus.
Work began on the new car in mid-1971 with production of a 1:4 scale model. According to Italdesign, Chapman was disappointed with the wind-tunnel test results with the model and halted the project, but the Italian coachbuilder pressed on and built a full-size mock-up on a stretched, modified Europa chassis. That nameless prototype, often simply called "the Silver Car", appeared on the Italdesign stand at the 1972 Turin Auto Show and the positive reception convinced Chapman to approve further development.
Development continued with production of a second prototype, registered as "IDGG 01" and known as "the Red Car", that would be a functional car. Design of the car's mechanical systems progressed, but was not complete when the Esprit was officially announced.
S1 (1976)
The Esprit was launched in October 1975 at the Paris Motor Show and entered production in June 1976, replacing the Europa in the Lotus model lineup. These first cars became known as "Series 1" (or S1) Esprits. The wedge-shaped fibreglass body was mounted on a steel backbone chassis. Power was from the Lotus 907 four-cylinder engine that was rated at in European trim and in US/Federal trim. The engine was mounted longitudinally behind the passengers and drove the rear wheels through a Citroën C35 5-speed manual transaxle also used in the SM and Maserati Merak. Rear brakes were mounted inboard, following contemporary racing practice. The Series 1 embodied Lotus' performance through light weight mantra, weighing less than .
Front suspension consisted of upper A-arms and lower lateral links triangulated by the anti-roll bar. Rear suspension consisted of tapering box-section trailing arms and lower lateral links. The half-shafts had no provision for plunge and handled some of the lateral forces. There were coil-over shock absorbers and disc brakes at all four corners. Steering was by an unassisted rack and pinion.
