The first had a Mercedes chassis with a twenty three litre, six cylinder Maybach engine which reached 100.75mph at Brooklands. The second had an early Mercedes chassis and an 18.8 litre Benz BZ series aero-engine and competed in Sahara desert races. The third had a 160 horse power Mercedes single overhead camshaft six cylinder aero engine and was tuned to produce 180 horse power, and lapped Brooklands at 112.68mph.There was a fourth version, known as the "Higham Special" was the largest capacity (27 litres) racing car ever to run at Brooklands.
