Game Informer gave the game a ratiing of 70/100, saying that "NASCAR Unleashed may be just another kart racer, but it's also not as foreign of a concept to the sport as you may think. Its drafting, rivalries, and car contact are certainly key aspects of the sport represented here – just not enough."
