ADR has its roots in an engineering business founded in the early 1950’s supplying Motorsport and non-motorsport companies with specialised, bespoke components. However it was not until 2001 that they produced the prototype of their first complete racing car, the ADR Sports 1000.
The ADR3 came with 2 engine/drivetrain options; the Suzuki Hayabusa 1300cc motorbike engine, available in several states of tune, or the Honda 2 litre K20 automotive engine mated to the Hewland FTR gearbox.
