NEW PRODUCT : AUTOCAD INTERFACE FOR DYNAMIC RESPONSE , 
Australian Grand Prix Simulation

Preston & Pleydell, engineering consultants and co-designers of 
the Australian built Spectrum 05 Formula Ford, have recently 
updated their circuit simulation software to include a link to the 
popular CAD package AutoCAD.  The package, called Dynamic 
Response, is similar in design to the Renault package seen 
recently in Auto Action and Motorsport News for predicting circuit 
lap times.  Design engineer Mark Preston said, “Simulation is the 
way of the future as race car teams try to discover what variables 
will give the most gain without expensive track testing programs. 
 Contact with Formula One teams such as Williams and Benetton has 
shown that they too are only just beginning to develop their own 
in-house packages as the area of research is only very new.”

At the recent Australian Grand Prix the program predicted a lap 
time of 2:11.70 sec for the Formula Fords, and 1:57:87 sec for the 
5 litre Touring Cars within 2 % of the times set in Friday 
practice, 2:10.0 and 2:00.06 respectively.  “Considering we do not 
have access to the amount of data F1 teams receive we are quite 
happy with the accuracy of our results as many of the F1 teams 
were surprised to find the track with more grip than expected”, 
said Mark.
