The Chittys were built and stored at Higham Park, Zborowski's country house at Bridge near Canterbury in Kent. The cars were so loud that Canterbury reportedly passed a by-law prohibiting them from entering within the city walls. The origin of the name "Chitty Bang Bang" is disputed, but is believed to have come from a salacious World War I song.
Chitty 1 was a chain-driven customised Mercedes chassis containing a 23 litre 6 cylinder Maybach aero-engine. It won two races at its debut at Brooklands in 1921, coming second to another Zborowski car in a sprint race at the same event. Chitty 1 was fitted with four seats and a crude, over-sized exhaust pipe, in order to misguide the handicappers and spectators. Its top speed on the day was 100.75 miles per hour (162.14 km/h).
For its next outing, Chitty 1 was refitted, as a two-seater with a cowled radiator and a properly plumbed exhaust. It attained nearly 120 mph (190 km/h) on one occasion, and had its race handicap consistently reappraised. It subsequently crashed, removing three fingers from a timing official. The car was rebuilt, and passed into the ownership of the sons of Arthur Conan Doyle, but was quickly retired as a racing car, and was later butchered for spare parts.
Chitty 2 had a shorter wheelbase, an 18.8 litre Benz Bz.IV aero-engine and the coachwork was carried out by Bligh Brothers of Canterbury, England. It was never as successful as its predecessor, but took part in several road races, including a Sahara Desert expedition in 1922. It later became the property of the Crawford Auto-Aviation Museum in Cleveland, Ohio. It is now part of the private collection of Bob Bahre at his home in Paris Hill, Maine (the former mansion of Hannibal Hamilin, Lincoln's first Vice-President).
Chitty 3 was based on a modified Mercedes chassis with a 160 hp (120 kW) Mercedes single overhead camshaft six cylinder aero engine, tuned to produce 180 hp (130 kW). The car recorded a lap of Brooklands at 112.68 mph (181.34 km/h). Louis Zborowski later used it as his personal transport, and drove it to Stuttgart when he negotiated to join the Mercedes racing team.
Chitty 4 (also known as the Higham Special) was Louis Zborowski's largest car yet. Using a 450 hp (340 kW) V12 Liberty aero engine of 27 litres capacity, with a gearbox and chain-drive from a pre-war Blitzen Benz, it was the largest capacity racing car ever to run at Brooklands. Still not fully developed by the time of Zborowski's death in November 1924, it was purchased from his estate by J.G. Parry-Thomas for the sum of £125.
Parry-Thomas rechristened the car Babs and rebuilt it with four Zenith carburettors and his own design of pistons. In April 1926, Parry-Thomas used the car to win the Land speed record at 171.02 mph (273.6 km/h). However, he was killed in the vehicle in a later attempt on 3 March 1927. Babs was buried at Pendine Sands in Wales, but was later recovered and restored and is now on display at the Pendine Museum of Speed.
