GT4 are lighter, classic cars, and while they may not have the horsepower of the gt5's and gt6's, they more than make up for it in agility! GT4 cars only have 4 gear dice. However, they have 3 Coast dice instead of 2, giving them a major advantage on tricky sections of track where your speed is limited. As with GT5, GT4 is fully compatible with Solo mode, and has been added to the scoring sheet.
