Captain Planet and the Planeteers

Smog Hog (1x15)

:

Hoggish Greedly gets his nephew a smog hog for his birthday. The locals see it, and decide they want one of their own, and Greedly suddenly sees dollar signs. He hijacks a factory, run by Dr. Goodair, the creator of a fuel-efficient automobile, so he can assemble more smog hogs to be sold. The only ones capable of stopping him in his tracks are the Planeteers.
