The Wilson preselector box was (and still is) the most civilised way to transmit power from the engine to the wheels. However, as Greig points out, they absorb a lot of power. The smallest cars that were fitted with them were the Riley 9, the Amstrong-Siddely 10hp and the Lanchester Ten. The Rileys went reasonably well, but weren't as quick as the manual cars, whilst the Armstrong and the Lanchester were pedestrian to say the least.
