March 92S concept modelPresented May 17, 1991, at the Silverstone circuit, the 92S was to be March's standard bearer for their re-entrance into the 3.5 liter Sports Car World Championship.  "When we assessed the sportscar market's needs we realized that the task was to fill the void left by Porsche and that most sportscar teams require a complete turn-key package.  What is needed is a whole car, not a chassis and engine separately", David Reeves, Managing Director of March Engineering.  March intended to initially build 8 chassis for sale with testing to begin in the Fall of '91.  European and Japanese customers were anticipated.
March 92S concept modelThe car was first presented to the public via this presentation model.  Note that it is only half represented (the split line is down the middle) and that the model was photographed against a mirror for these images.  Andy Thorby had been recruited from Toyota and the presentation model was his design.  But Nick Wirth's Simtek group was brought in as a consultant and took over the car's initial wind tunnel studies.  According to David Reeves on the car's presentation day, "What you see here is the concept model which was part of the design brief given to Simtek.  Of course the final 92S design is being refined and refined and I have no doubt that the prototype will only bear a passing resemblance to the concept model."
March 92S wind tunnel modelWirth appears to have discarded all of the work done by Thorby and it can be argued that this toe-in-the-water wind tunnel model is decidedly less mature than the concept model.  Customers for the 92S never materialized and March went out of business with Simtek following suit. The model was purchased from the auction of the Simtek properties upon that organization's liquidation.
