Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "cars.ini" file in the "cars" sub-folder in the game directory. Change the "mass=" value to "100" for a faster car.

Open the folder of a powerful car, such as the F1, F50, etc. Copy the "car.ini" file from here and paste it over the original "car.ini" file of a slower car in its own folder (for example, the Elise). This instantly gives that car the speed and handling characteristics of the better vehicle. Note: Back up the original "car.ini" file of the slower car in the event that you want to revert it back to its standard settings.
