From the looks of other reviews, it sounds like there are different versions out there, but the one we received is AWESOME. The car required 3 AA batteries and the controller needs 2 AA batteries. The car has a removable driver and when you put him in the seat, It goes "VROOM VROOM" in a little boy's voice. When you push the steering wheel, it makes a start-up engine sound. The best part is there is also a button on the car that plays a little Latin-like song and makes the headlights flash! Someone else posted that it makes annoying music when you drive it but ours doesn't. It only plays music when you push the button on it. The car goes great on tile or carpet. Our 11-month-old loves to chase it and play with the little driver. What else could you ask for for the price! An added bonus: The box has the most amazing English-from-Chinese translations!
