Using the Classification Chart:

  • Simply move your cursor across the chart. Anywhere the chart turns yellow, you can click and get information.
  • If you click on a cell in the chart that has the power-to-weight factor (numbers in the cells in the middle of the chart), you will open a page that shows you all the classes for the car (left-hand column) and engine (top columns) combination.
  • If you click on some of the cells at the top of each column that describe the engine, you will open a page that show the engine tech specs, or blueprint information.
  • If you click on one of the cells in the left column that shows the car description, you will open a page that shows information about that car-model-body style.
