Lemons

The Lemons are antagonists of Cars 2. They are made up of four different families, based on their models: Gremlins (AMC Gremlin), Pacers (AMC Pacer), Trunkovs (ZAZ Zaporozhets) and the Hugos (Zastava Koral). There is also one Zündapp Janus. Because they are considered as ugly and weak cars, the lemons feel rejected, and reject the world in return. The elite cars are equipped with side weapons, consisting of machine guns and missile launchers. Many of them died in the many chases and fights during Cars 2 

They have a TV camera that is used to eliminate the racers.
