150.87 mph / 242.80 kph – Sunbeam V12

These day’s if one had just £500 to spare it would probably not be too difficult to scan a few classified car ads and find a car that was still capable of reaching 150 mph.

When Sunbeam’s chief engineer and racing team manager Louis Coatalen conceived today’s featured Sunbeam V12 in 1920 the World Land Speed Record stood at 124.09mph / 199.70kph set by Lydston Hornsted driving a 200hp Benz at Brooklands in June 1914.

Louis’s idea was to fit a 350 hp 18.3 litre / 1116 cui V12 Sunbeam Manitou V12 aero engine in to a chassis and clad the vehicle in the most aerodynamically slippery shape that could be devised.

Harry Hawker was given the task of driving the Sunbeam V12 at two Brooklands race meetings in 1920, but the car suffered from damage after a tyre blew on the Whitsun Weekend and then could not start after the engine stalled in August, but René Thomas drove the car to a new 108 mph course record on the Gaillon Hill Climb in France.

In 1921 Kenelm Lee Guinness drove the car at Brooklands recording a top speed of 140 mph and an average lap speed of 116 mph at the Autumn meeting, the following year Kenelm set a one way flying kilometer record of 133 mph, but this was never recognised as a World Land Speed record for which the speed is determined by the average of two runs in opposite directions.

Malcolm Campbell borrowed the Sunbeam V12 to compete in the 1923 Saltburn Speed Trials and recorded a one way run of 138 mph which was enough to convince him that he should purchase the car for further Land Speed Record attempts in 1924.

After Ernest Eldridge raised the official Land Speed Record to just over 145 mph aboard the FIAT Mephistopheles, a vehicle I shall be looking at next week, in June 1924 at in Arpajon in France, Malcolm took his now blue and silver, previously green and silver, Sunbeam to the Pendine Sands in September 1924 and recorded a two way average speed of just over 146 mph for his and the Sunbeams first World Land Speed Record.

In July 1925 the combination returned to Pendine Sands and raised the World Land Speed Record to 150.87 mph / 242.80 kph a record that stood for just under a year when a car that I shall be looking at in two weeks took the record up to 170 mph.

Racer and Runabout – Arnott Sports #AT112

Daphne Arnott was born into a mechanical world in 1926, her Grandfather appears to have been captain and secretary of the Bath Road Club and ‘in control of’ MMC built Werner Motorcylces and her father was responsible for the Arnott Superchargers sold through Carburetors Ltd in North West London.

Daphne spent many childhood hours spectating at Brooklands and in her early teens she became competent mechanic. During the ’39-’45 war she was employed by the Hawker Aircraft company.

In 1948 Daphne joined the family business Carburetors Ltd and by 1951 she had created a department within it to design and manufacture 500 cc / 45.5 cui Formula 3 cars with assistance from the works manager George Thornton.

After Bob Brown of Bromley won first time out in the Arnott, Daphne built 8 copies, one of which became a streamliner in which John Brise set 500km average speed record of 108mph at Montlhery in 1953 which still stands.

For 1955 Daphne came up with the 1100 Sports model seen here, complete with wishbone independent suspension, which was entered into the Le Mans 24 hours.

It is a measure of the esteem in which she was held that her Arnott, one Lotus and one Kieft were each given a new Coventry Climax motor with which to compete in the 24 hour classic.

Jim Russell, of racing school fame and Peter Taylor were the drivers but they crashed during practice after which Daphene had an Arnott supercharger fitted and used the car as her daily driver for 20 years.

A second attempt was made at Le Mans with another Coventry Climax powered Arnott Sports in 1957, this time Jim Russell and Peter Taylor qualified but retired with ignition problems after completing 46 laps and that seems to be the end of the Arnott story as a manufacturer.

In all 25 Arnott Sports are thought to have been built with fibre glass bodies. The current owner bought today’s featured vehicle from Daphne Arnott after it had spent some time disintegrating in a barn in 1998.

In 2003 this Arnott Sports still fitted with it’s original Coventry Climax motor #FWA400/3.6264, Arnott supercharger, MG TC gearbox and ENV back axle was given a £30,000 plus overhall by Sigma Engineering in Dorset.

When I saw this remarkable testimony to the grit and courage of a little remembered British entrepreneur Daphne Arnott at Goodwood Revival last year it was being offered for sale, if you are interested I have contact details for the owner. Usual disclaimers apply.
