While the game doesn't look as good as it would on other systems, it still has all the glitz and sparkle that makes the license stand out. Race tracks are twisted and colorful, and seem to be inspired by Hot Wheels tracks more than standard raceways, while the cars resemble their movie counterparts pretty well. The characters look more like modernized versions of the classic cartoon series then faithful replications of the movie actors, which isn't a bad thing necessarily.
Sound is one of Speed Racer's strong points. The roar of the engines sounds good and is only really surpassed by the in-game one-liners of the other racers. Each of the characters are voiced by the same actors from the movie, and while there isn't a lot of dialogue, what is there is timed right and doesn't get annoying. During races, overtaking opponents will cause them to shout an exclamation or vow vengeance; meanwhile if you pass an ally, they will cheer you on. I found both your allies and rivals had just the right amount of annoyance in their voice when you tapped into them. It might be a minor element to the game, but Speed Racer's sound makes the game feel a bit more than just a racing game with the Mach 5.
