Company founder, David Mitchell, started his automotive industry journey by fabricating and machining parts for racing cars as a paid hobby. Growing demand for David’s work inspired him to established Autosport Engineering (ASE) in 1999.

The company rapidly gained success and recognition for producing beautifully designed and meticulously crafted parts in the turbo motorsport and streetcar scene.

Constantly innovating and striving to be ahead of the curve, David foresaw the demand for performance parts in the four-wheel drive market, establishing ASE as of one the earliest aftermarket manufacturers to support diesel four-wheel drives.

As demand (and profitability) for diesel 4WD parts outstripped performance car parts, ASE metamorphosed into HPD in 2010.

HPD was recognised for their ongoing commitment and support of local jobs in Edwardstown with an Innovation award from the City of Marion in 2021
