Spine Buster was introduced in the Acceleracers series. In the series, it is the beloved car of Mark Wylde, built after his Corvette Stingray was impounded. The car has a 1680hp ram exhaust V10 engine with nitromethane-burning ram air and magnesium steel alloy wheels. The ram exhaust extinguishes the fire that was generated because the engine is so powerful that the combustion cycle overlaps the exhaust cycle. This V10 has custom-built exhaust pipes, with half running to the left slightly above the body, while the other half of the pipes run right and below the body. The intake goes into the furnace on the right of the vehicle, then slingshots the exhaust to the chamber on top the engine and to the spines on the tail, then out the back. This produces a deep hissing sound when the car moves and is what gave Spine Buster its name. Spine Buster has many features to save weight; It does not have front fenders and there are deep pockets on the sides that draw air to the rear brake inlets. The car has swooping rear fenders and a steel, solid angled spoiler that weighs down the back. If the front wheels go past the body, then this car cannot steer and this weight distribution makes for terrible handling. Although this car was normally driven by Wylde, in the Metro RealmAcceleracers movie, this car was driven by Monkey McClurg, but was destroyed by a W1 drone and a sweeper.
In the series, Spine Buster was replaced by the very similarly-designed Flathead Fury. The Hot Wheels version of Spine Buster has no shifter. Also, this is one of the only Hotwheels with open radiator outlets. This car resembles the Ford GT.
Spine Buster has been released in the following 1/64 scale versions:
