This is a prototype of Speed Racer by Radical Entertainment. Some differences that could be noted are as follows: Upon boot “Beta 15 Mon 7 3 20” can be seen under the Accolade publisher logo, each race length is described with the amount of miles instead of the number of laps, and some minor color and graphical differences.
