The Jay Leno Tank Car is a car from Gran Turismo 4, Gran Turismo 5 and Gran Turismo 6. It is a copy of the real life "Blastolene Special", designed and made by glass specialist Randy Grubb. The car features a Continental AV1790-5B tank engine, powering a custom designed aluminum body. The car currently housing this monstrous engine weighs just one-eleventh that of the M47 Patton Tank that it came from. The 810BHP that the engine produces, coupled with the relatively light bodywork, creates acceleration that compares to most modern day sports cars.
