Motor sport in all its forms enjoyed great popularity and significance during the interwar years, with British manufacturers Bentley, MG and Sunbeam all known for their commitment to it. But Alvis also forged its early cars in the white heat of competition.
Despite early financial unrest, the firm's engineers – two of whom came from Daimler in 1922 – had their eyes firmly set on sporting success. From the Brooklands 200 Miles race to Le Mans and the UK hillclimb scene, lessons learned here would influence Alvis' road-car designs for many years.

Though just one year separates RW12 and HP 6161, the technology employed could have come from a different era
The 1924 car is sleeker than HP 6161, with a lower centre of gravity helping to improve cornering
