Snot Rod is a punky drifter car, that is part of Boost's tuner gang. He has a serious congestion issue, that makes him sneeze all the time, which makes fire shoot out of his sideburners. He is currently residing in the Radiator Springs prison, after his attempt to steal several goods from the townsfolk. He is the only muscle car of the gang.
Snot Rod took his doctor's advice and headed west to find some clean, crisp mountain air to relieve his chronic allergies. On the way he met up with Boost, DJ, and Wingo. The highly modified car group set him as the gang's head of security and crowd control. He still has allergies and explosive sneezing attacks, but his ability to clear the road of pesky traffic is unmatched and much appreciated by his buddies who like the road all to themselves.
In Cars, Snot Rod is one of the four tuner cars that mess with Mack on the highway, which causes Lightning McQueen to fall out of his trailer. They were about to have Mack pull over, until Snot Rod sneezed, which woke Mack up and they were able to get away. They were later seen in the end credits speeding on the route to Radiator Springs, only to get caught by Sheriff and put into the impound. They were later sent to pave one of the roads with Bessie, who splashed hot tar on them.
In Cars: The Video Game, Snot Rod was first seen with the rest of his gang in Tailfin Pass, making sure that Lightning did not cross "their road". He was challenged to a race by McQueen, but failed terribly. He was later hired by Chick Hicks, to steal Lightning's goods from Mack on the interstate. Once they were done with their job, Mack radioed Sheriff, who passed the info on to Lightning. Lightning took action into his own hands, and hurried along the interstate to catch the group. He was able to smack the goods out of their hands, and brought them back to Radiator Springs, where they were arrested.
In Mater Saves Christmas, Snot Rod is part of the group of tuner cars who tried to steal goods from the townsfolk.

Snot Rod is a Bragatron Roadburner. His paint stripes suggest a Dodge Challenger. He seems to be based on a 1970 Plymouth Barracuda. He is proud of his custom grille logo.

His sneezes cause wide open throttle, instant acceleration and nitro fire from the headers (exhaust pipes).

Actually a Dodge bodied AA/FC; nitro burning funny cars which are the quickest and fastest full-bodied cars on the planet. The top quarter mile speed 334.32 mph, low elapsed time 4.464 seconds - it would be a huge sneeze.
His name is a play on the word Hot Rod, which are typically American cars with large engines modified for linear speed.
