1987 Lotus Esprit NA

Throughout its 28 year history there were many variations of the Lotus Esprit but all of them can be grouped into two design groups.

The first category is what is commonly referred to as the Giugiaro Esprit; named after the original Italian designer of the car, Giorgetto Giugiaro. The easiest way to identify those cars is if the car was built before 1988 MY (model year) then it is a Giugiaro Esprit. Styling-wise, the Giugiaro Esprit is distinguished by sharp angles and a wedge shape.

In 1988, designer Peter Stevens who is also famous for designing the McLaren F1 supercar softened the crisp edges of the Esprit. It was more modern looking and more sexy from a design perspective.

The Esprit was built completely by hand. The Esprit production line was established back in 1976. Until the end of production in 2004, nothing changed much since those days a quarter of a century ago. There were only 21 people on the line. Each car took about 584 man-hours to assemble.

With multiple people working on the car, total assembly was accomplished in about one week. One car rolled out of the assembly line every business day. Upon completion, each vehicle was driven on the test track.

After the test drive, the car was put on a lift and thoroughly inspected and adjusted. Afterwards, the car was test driven a second time to verify everything was perfect.

Although the Esprit was developed over 30 years, the basics remained the same throughout its life, all the way from the S1 through to the very last V8 02. The basics are pure supercar with its two-seater, mid-engined, rear wheel drive layout and that wedge shape.

The Esprit was built around a steel backbone chassis, with the body panels made of Glass Fibre. All Esprit engines were designed and produced by Lotus from the first 2.0 liter inline 4 to the strong V8. Gearboxes on the other hand were sourced from other manufacturers. This was done as Lotus couldn’t afford to buy the tools to make their own gearboxes due to the small Esprit sales volumes.

October 1987 to September 1990. In the latter part of 1987, Lotus produced 2 Esprit models, the top of the range Esprit Turbo and the cheaper Normally Aspirated “Esprit”. The cars were virtually identical visually. Known as the Steven’s Esprits.
