When five-year-old Evan wore the wheels on his Lightning McQueen Powerwheel down to plastic nubbins, his dad saw an opportunity for a father/son project. This video shows how they slicked up the tiny car with features like "an aluminum back half chassis, dual sealed gel batteries with an output of 24 volts, a 500 watt .66 horsepower electric motor, disk brake, throttle modulated variable speed control with reverse and sparco battery cut off switch."

That thing's got a lot more oomph than the original -- toward the end you get to see tiny Evan skimming around the racetrack like a Mario Kart character. Hey Dad, in case you're taking suggestions for future modifications: Airbag.
