Victor and the Vroom

Victor looks similar to the other cars in his class, but under his hood is an engine that sounds like no one else's:

VROOM ZOOM

TIKKA TAKKA

REV REV ZIKKA ZAKKA

His engine helps him do interesting things the other

cars can't, but the sound also gets him in a lot of trouble. Should Victor fix his engine? Or does the engine sound exactly the way it's supposed to?
