Lotus 88
From Wikipedia, the free encyclopedia
The Lotus 88 was an innovative ground effect F1 car designed by Colin Chapman, Peter Wright, Tony Rudd and Martin Ogilvie of Lotus as a response to technical regulations introduced in 1981 by the FIA to curb the ground effects cars technical excellence.
By 1981 the ground effects cars were so efficient and so fast that the drivers were suffering from the tremendous g-forces involved in cornering and braking. The FIA banned the moveable skirts fitted to the bottom of the cars' sidepods that were vital for achieving consistent ground effect and regulated a mandatory ground clearance of 6cm, in the interests of driver safety. The Brabham team were the first to circumvent the rules using hydropneumatic suspension systems which compressed under aerodynamic loading and lowered the Brabham BT49 onto the track. This had the side effect of rendering the car without any sort of suspension, causing the driver to be buffeted even more than before. However, the performance gains were such that other teams were soon following suit - although most had difficulty in replicating the Brabham system and used a simple switch to lower the car. Chapman had other ideas.
The 88 used an ingenious system of having a twin chassis, one inside the other. The inner chassis would hold the cockpit and would be independently sprung from the outer one, which was designed to take the pressures of the ground effects. The outer chassis did not have discernable wings, and was in effect one huge ground effect system, beginning just behind the nose of the car and extending all the way inside the rear wheels, thereby producing massive amounts of downforce. The car was powered by the Ford Cosworth DFV engine. Lotus drivers Nigel Mansell and Elio De Angelis reported the car was pleasing to drive and responsive.
Other teams were outraged at this exploitation of the rules and protests were lodged with the FIA, who consequently banned the 88 from competing. Chapman was adamant the car was legal and challenged the other teams and the FIA at every turn, but the decision stood. Chapman was forced to update two of his Lotus 87 chassis as replacements for his thwarted brainchild. The Lotus 88 therefore remains a curiosity from a bygone age of F1. Some of the 88's aerodynamics and layout were worked into the successful Lotus 91 which followed in 1982.
