Half A Car – Lotus Ford T 87 #87/R2 & #87/R4

For the 1981 World Championship Lotus had developed the twin chassis Lotus 86 which I looked at last week, no sooner had testing of that car been finished than the ruling body of the sport outlawed the skirts on which the car depended to seal the airflow beneath the body of the car and mandated a minimum ride height.

This led to the development of the Lotus 88 which had twin chassis as did the 86 but no skirts and a 6cm minimum ride height as mandated by the new rules. Unfortunately while the governing the body of the sport accepted the Lotus 88 as legal most of the other teams did not declaring that the second outer aerodynamic chassis was a banned movable aerodynamic aid and not a fully suspended chassis.

Set against a back ground to these semantic arguments between the grandee teams of Ferrari, Renault and Alfa Romeo going up against the garagistes of Brabham, Lotus, McLaren, Williams et al made of high drama and in this instance almost every body building cars turned against Lotus in denouncing the Lotus 88 which meant that it only ever took part in a couple of practice sessions.

For the first half of the 1981 season Lotus were therefore forced into running the Lotus 81 from the 1980 season. By the time the Formula one circus arrived in Great Britain Lotus made one final attempt to run the Lotus 88 in practice but were again refused by their fellow competitors and so Lotus ran the 88 sans second aeroydynamic chassis and with more conventional aerodynamic side pods and wings as #87/R2 is seen being driven by Nigel Mansell during practice for the British Grand Prix at Silverstone in 1981 and #87/R4 is seen with the later front wings at Hall & Hall and in the Paddock at Silverstone during the classic meeting earlier this year.

The single chassis version of the Lotus 88 is known as the Lotus Type 87. The highlight of the Lotus 87’s half a seasons competition career was a couple of 4th place finishes, for Elio de Angeles in Italy and Nigel Mansell at Ceasers Palace.

Chassis R2 was used by Elio de Angeles in Monaco, Spain and France scoring a best 5th place finish in Spain, Mansell took the car over for the British Grand Prix and failed to qualify. There after this car was used as a spare for the remainder of the 1981 season and the first race of the 1982 season in South Africa.

So far as I have been able to determine chassis #87/R4 seen in the more recent photo’s was driven by Nigel Mansell in at least four Grand Prix during the second half of the 1981 season. Note that the use of space age Carbon Fiber and Kevlar was becoming widespread by 1981 the following season the majority of Formula One monocoques were made from the material with the exception of Ferrari.

The absence of any bodywork around the rear suspension and exhaust shows what a rush job it was to get the Lotus 87’s to the grid most of the contemporary cars of the period had the rear axle covered in body panels by 1981 including the 1981 British Grand Prix winning McLaren MP4/1 of John Watson.

My thanks to Rick Hall if Hall & Hall for generously allowing me to take the photos of #87/R4, which is for sale, on his premises.

Chassis or Aerodynamic Aid – Lotus Ford 88

The Lotus 88 was a development from the ideas tested with the twin chassis Lotus 86. It differed, and was developed, in two crucial respects from the Lotus 86 it was designed to run with out skirts to seal the flow of air and would meet the 6 cm minimum ride height mandated by rules around late in 1980 for the 1981 season.

By having a secondary independently sprung chassis Lotus hoped to avoid the need to run their car with solid suspension which aided the road holding of ground effects pioneered by the Lotus Ford 79 which were sucked to the road surface as they moved through the air.

Gordon Murray designer at Brabham also came up with a solution to the 6 cm ride height rule which involved using hydraulic rams to raise the car above the minimum ride height in the pits, the only place the measurement could be checked, and lowering the ride height out once out on the track. This left the Brabham running effectively solid suspension once out of pit road.

All of the teams protested that the second Lotus chassis was in fact an independently aerodynamic aid and eventually the ruling body changed it’s mind having accepted the idea of a twin chassis car before the season started.

As a consequence after being protested during practice for the the United States West, Brazilian and British Grand Prix Lotus withdrew the 88 bodies with out ever having raced and used the more conventional Lotus 87 which used inner Lotus 88 chassis but with conventional side pods to generate ground effect and a similar hydraulic ram system for the suspension as used by Brabham.

Colin Chapman is said to have been disappointed that the twin chassis Formula One cars developed with Peter Wright, Tony Rudd and Martin Ogilvie were never allowed to compete believing that Formula One was supposed to be a proving ground for new innovation.
