No, but I studied the first two years of a mechanical engineering degree, before comming to my senses and quitting for somthing eaiser and more interesting. You may find the following table interesting, it gives stopping distances for around 250 different cars. http://www.movit.de/htm/tabstop.htm The lotus elise is shown as taking longer to stop than most cars in the list, and longer than every Mercedes in the list. However, after reading the following, I doubt testing was done properly. http://www.elises.co.uk/diary/2001/august.html 'They do mention the chassis protection but only manage to stop the elise in 27.18m (in the dry) from 40mph, making it the worst car tested. In the text however they say they managed to get it down to 18.67m after practice, making it the 3rd best car! Surely a pre-requisite for this test is that the driver knows how to drive the car? Stamping on the pedal to lock the wheels is not going to provide very good stopping distances. ' So who do we believe? Didn't the GT4p game creators test the cars to get their performance figures for the game? I hope they didn't use press released figures.
