The car bears a strong resemblance to the Blue Flame, which was a rocket-powered vehicle Gary Gabelich used to break the land speed record, at 630.478 mph (1014.656 kph). In-game, it is a white rocket car with blue stripes that shoots a large blue flame out of its exhaust as it is driven. It is one of the fastest, if not the fastest car in the game, but is hindered by its poor handling and strength.
The Speed Rocket is found only in Level 1. It is located outside the Solid Gold House in the richer area of Springfield, beside the "Vote for Mayor Quimby" sign. The house can be found at the vertex of the U-turn between Mr. Burns' mansion and the gas station by the draw bridge.
