Fatbax was a series, which debuted 2004 in the First Editions series. All 10 different cars has giant rear wheels and tiny front wheels. The cars itselfs were wedge-shaped and has mostly exaggerated engines.
The cars with this funny design was a financial loss for Mattel and the fatbax weren´t sold good and were found in stores trough 2005. So the Fatbax will never be produced again.
The rea wheels has all the same size on every Fatbax model.
