Ridge Racer Type 4

R4: Ridge Racer Type 4 is the fourth game in the Ridge Racer series. There are 8 tracks (with reverse variants, for a total of 16 layouts) and 321 vehicles, all of which are fictional. This iteration was one of the first games on the PlayStation to feature gouraud shading on the polygons, giving the game a visual depth that was previously missing. It was also the first Ridge Racer game on the Sony system to feature a two-player split screen mode, and featured two different driving models.
