At this time Carden was taking class records at Brooklands, a mere fifteen miles away, in cars that had engines of 350 to 1000ccs capacity. They had solid rear axles with an inboard brake drum and externally-contracting brake band.
It was after many decades later that F1 designers agreed with this layout: recumbent driver, rear engine, monocoque construction.
Carden was a most ingenious and imaginative designer and worked in many fields. By the time he was making these monocars at the age of twenty, he had built his own aircraft and a working model of a tidal-powered generator for the Severn estuary.
Although he was a Baronet, he had no money and had to sell his designs to finance his next enterprise. Although he was a busy captain in the RASC during WW1, he found time to sell the cyclecar business including the Teddington factory to Ward & Avey, the car becoming the AV Monocar.
