The Lotus Esprit Series 2 Sports Car

A review of The Lotus Esprit Series 2 Sports Car, covering development, important features, and technical data of this the eighteenth model in the Lotus range.

In this Article, I offer a nostalgic look at the Lotus Esprit Series 2, one of an elite group of classic cars, which was manufactured during the period 1977 to 1981.

The Lotus Esprit Series 2

During its two year production run, the Series 1 Esprit had received a number of criticisms from the press and customers, which caused Lotus to seek ways to improve the car.

The outcome of this was the launch of the two door, two seater, Series 2 variant in June 1978.

The only mechanical changes were the introduction of a modified camshaft, and the replacement of the original Wolfrace wheels with 14 inch Speedline alloy equivalents.

The most obvious external changes were:

  • Front under nose spoiler was blended into the shape of the car
  • Engine compartment air intakes now moved behind the rear side windows to facilitate the movement of cold air into the engine bay
  • Rover SDI rear lights replaced those from the Fiat X19
  • Headlights were now lifted by two electric motors
  • Redesigned, wider seats
  • New instrument cluster and a digital clock
  • Redesigned engine cover
  • The emblem “Esprit” replaced “Lotus” on the bonnet, with “Esprit S2” at the rear

There was a promotional coup when Mario Andretti and Ronnie Peterson received the first two Series 2 sports cars.

At the NEC Motor Show in October 1978, Lotus launched a limited edition of 100 of the Series 2 which displayed the black and gold John Player Special livery.

This was to commemorate Mario Andretti winning the Formula 1 World Championship, driving a Lotus 79 JPS Mark 4.

Each of these 100 cars received an individual plaque, fitted to the dashboard, which had been personally signed by Colin Chapman.

Between 1978 and 1979, it has been estimated that, in fact, 149 of the JPS variant were built.

The Series 2 still retained a drag coefficient of only 0.34, whilst its top speed was 124 mph, with a 0-60 mph time of 8.4 secs, and an overall fuel consumption of 24 mpg.

Between June 1978 and January 1980, when the Series 2 was discontinued, a total of 1,060 units were built.

The Lotus Esprit Series 2.2

The further development of the Esprit was by means of the introduction of a more flexible and powerful engine.

The solution was not only to increase the stroke of the original Type 907 engine, which would provide it with more low speed and mid range torque, but also adding a new crankshaft.

The result was that the capacity was increased from 1973 cc to 2174 cc, with a corresponding increase in torque.

This engine was now designated the Type 912.

Furthermore, an equivalent Type 911 engine was used, in March 1979, to power the new Sunbeam Lotus “hot hatch”, designated the Lotus 81.

In January 1980, the Series 2 Esprit was replaced by the Series 2.2 sports car, which now incorporated the new Type 912 engine, a galvanized chassis, and a modified, part stainless steel, exhaust system.

Engine Power Torque

1973 cc Type 907 as used 160 bhp @ 6200 rpm 140 ft/lbs @ 4900 rpm in the Series 1 and 2

2174 cc Type 911 as used 150 bhp @ 5750 rpm 150 ft/lbs @ 4500 rpm in the Sunbeam Lotus

2174 cc Type 912 as used 160 bhp @ 6500 rpm 160 ft/lbs @ 5000 rpm in the Series 2.2

Externally, it was only the new “Esprit 2.2” badge at the rear that heralded the uprated engine.

It used two twin choke Dell’Orto DHLA4SE carburettors, a glassfibre reinforced plastic (GRP) body, 9.7 inch front disc brakes and 10.6 inch rear discs, and a compression ratio of 9.4:1.

The Series 2.2 was produced between May 1980 and June 1981, when only 88 units were built.

This model was introduced as a stop gap measure, prior to the introduction of the Series 3 variant.

This marked the end of the Lotus Esprit Series 2

Perhaps this stroll down memory lane might have answered, or at least shed light on, a possible question:

Which Morgan Sports Car is Your Favourite?

However, should this question still remain unanswered, I will be reviewing, in some detail, in future articles within this website, the entire range of Morgan sports cars which were featured in the memorable era spanning 1911 to 1996.

I hope you join me in my nostalgic travels “down sports car memory lane”.
