The Napier-Campbell Blue Bird was a land speed record car driven by Malcolm Campbell. Its designer was C. Amherst Villiers and Campbell's regular mechanic Leo Villa supervised its construction. [1]
This was Campbell's first car to use the Napier Lion aero engine. His intention was to surpass his previous Sunbeam Blue Bird's achievement of the 150 mph barrier and to reach 200 mph.
When first built, the car used a Napier Lion engine of around 500 bhp. It was of conventional form with a front-mounted vertical radiator and the driver behind the engine. The three banks of the W-12 engine were hidden behind bulges in the narrow bonnet, with exhaust stub pipes protruding.
Bluebird's first record attempt was on 4 February 1927 at Pendine Sands. [2] A peak speed of 195 mph (314 km/h) was achieved, tantalisingly close to the magic 200 mph (320 km/h), but the two-way average recorded for the record was lower, at 174.883 mph (281.45 km/h). [3]

The 1927 record was short-lived, as Segrave's Sunbeam 1000 hp achieved both the 180 mph and 200 mph targets a month later. This prompted Campbell to rebuild the car as "Blue Bird III" for 1928. He persuaded the Air Ministry to allow him a Schneider Trophy-tuned "Sprint" engine, as fitted to the Supermarine S.5 seaplane, of 900 hp (670 kW).
Improved aerodynamics were innovatively tested in Vickers' wind-tunnel by R.K. Pierson, their Chief Designer. Blue Bird’s body shape was substantially changed, with the famous coachbuilders Mulliner producing the bodywork. The results were unorthodox. A vertical tail fin was added for stability, a first for Blue Bird and land speed record cars. Open spats behind the wheels also reduced drag. The biggest change was to the radiators, which were moved to the rear of the car and mounted externally. [4] These surface radiators were made by Fairey Aviation and contained 2,400 ft (730 m) of tube. [5] Removing the nose radiator allowed a low, rounded nose with better streamlining. [6] However, one French newspaper compared its looks to a whale.
Following Segrave to Daytona Beach, on 19 February 1928 Campbell took the record at 206.956 mph (333.063 km/h), breaking the 200 mph barrier for his first time. [7] Once again though he only held the record for a couple of months, losing it by a whisker to Ray Keech and the White Triplex.
Campbell sought a more predictable venue than a tidal beach, so he set off to survey possible sites by air. Africa showed promise, first at a site 600 miles from Timbuktu and so impractically inaccessible. A dry lake bed in South Africa, the Verneukpan, was still 450 miles (720 km) from Cape Town, but did have some chance of access. [8]
Blue Bird was rebuilt for a third time. The chassis, engine and drivetrain remained the same, but the bodywork was replaced with one built in Dumfries by Arrol-Aster. [9] This body was lower, requiring a hump around the cockpit where Campbell now sat astride the gearbox. The surface radiators were replaced by a conventional circular nose opening, covered by a distinctive "birdcage" grille. [10] [11]
Unfortunately, after a period of five years of no rainfall, it poured down almost as soon as they arrived. Campbell returned to Cape Town, where on his 44th birthday he learnt that Henry Segrave at Daytona Beach had set a new record in Golden Arrow at 231.44 mph (372.47 km/h). Blue Bird was unable to match this at the African altitude and climate, but he made the best use of the long course and set the world 5 mile and 10 mile records at 212 mph (341 km/h). [7]
After Segrave had raised the record in Golden Arrow by a whole 30 mph (48 km/h) though, Campbell knew that Blue Bird was beaten and began work on a new car, the Campbell-Napier-Railton Blue Bird.
Major Sir Malcolm Campbell was a British racing motorist and motoring journalist. He gained the world speed record on land and on water at various times, using vehicles called Blue Bird, including a 1921 Grand Prix Sunbeam. His son, Donald Campbell, carried on the family tradition by holding both land speed and water speed records.
Pendine Sands is a 7-mile (11 km) beach on the shores of Carmarthen Bay on the south coast of Wales. It stretches west to east from Gilman Point to Laugharne Sands. The village of Pendine is close to the western end of the beach.
John Godfrey Parry-Thomas was a Welsh engineer and motor-racing driver who at one time held the land speed record. He was the first driver to be killed in pursuit of the land speed record.
Reid A. Railton (1895–1977) was a British automotive engineer, and designer of land and water speed record vehicles.
The Sunbeam 350HP is an aero-engined car built by the Sunbeam company in 1920, the first of several land speed record-breaking cars with aircraft engines.
Sir Henry O'Neal de Hane Segrave was an early British pioneer in land speed and water speed records. Segrave, who set three land and one water record, was the first person to hold both titles simultaneously and the first person to travel at over 200 miles per hour (320 km/h) in a land vehicle. He died in an accident in 1930 shortly after setting a new world water speed record on Windermere in the Lake District, England. The Segrave Trophy was established to commemorate his life.
The British land speed record is the fastest land speed achieved by a vehicle in the United Kingdom, as opposed to one on water or in the air. It is standardised as the speed over a course of fixed length, averaged over two runs in opposite directions.
Golden Arrow is a land speed record racer that was built in Britain to regain the world land speed record from the United States. Henry Segrave drove the car at 231.45 mph (372.46 km/h) in March 1929 on Daytona Beach, exceeding the previous record by 24 mph (39 km/h).
The Campbell-Napier-Railton Blue Bird was a land speed record car driven by Malcolm Campbell.
The Campbell-Railton Blue Bird was Sir Malcolm Campbell's final land speed record car.
The Sunbeam Tiger is a racing car, built by Sunbeam of Wolverhampton during the 1920s. It was the last car to be competitive both as a land speed record holder, and as a circuit-racing car.
The Sunbeam Silver Bullet was a world land speed record challenging automobile built by Sunbeam of Wolverhampton for Kaye Don in 1929.
Kenelm Edward Lee Guinness MBE was an Irish racing driver of the 1910s and 1920s mostly associated with Sunbeam racing cars. He set a new Land Speed Record in 1922. Also an automotive engineer, he invented and manufactured the KLG spark plug. Additionally, aside from motorsport and mechanical interests, he was a director of the Guinness brewing company.
Speed of the Wind was a record-breaking car of the 1930s, built for and driven by Captain George Eyston.
Blue Bird or Bluebird is the name of various cars and boats used by Sir Malcolm Campbell, his son Donald and other family members to set land and water speed records.
Thomson & Taylor were a motor-racing engineering and car-building firm, based within the Brooklands race track. They were active between the wars and built several of the famous land speed record breaking cars of the day.
Jarvis & Sons Limited were South London-based motor dealers for Morris and MG, and latterly coachworks providing special bodies for various car chassis until after World War II.
An aero-engined car is an automobile powered by an engine designed for aircraft use. Most such cars have been built for racing, and many have attempted to set world land speed records. While the practice of fitting cars with aircraft engines predates World War I by a few years, it was most popular in the interwar period between the world wars when military-surplus aircraft engines were readily available and used to power numerous high-performance racing cars. Initially powered by piston aircraft engines, a number of post-World War II aero-engined cars have been powered by aviation turbine and jet engines instead. Piston-engined, turbine-engined, and jet-engined cars have all set world land speed records. There have also been some non-racing automotive applications for aircraft engines, including production vehicles such as the Tucker 48 and prototypes such as the Chrysler Turbine Car, Fiat Turbina, and General Motors Firebirds. In the late 20th century and into the 21st century, there has also been a revival of interest in piston-powered aero-engined racing cars.
Sunbeam Works Racing cars participated in the 1922 XVI Grand Prix de l'A.C.F. in Strasbourg. The race took place on 15 July 1922 and was run to a formula stipulating that maximum engine capacity should not exceed 2 litres and that the cars should be two-seaters weighing not less than 650 kg. The formula was to remain in force for four years producing "fields of brilliance to be unequalled for many years" it was the first rolling massed start in the history of Grand Prix motor-racing.
The 1921 S.T.D. 'Works' Grand Prix chassis was built to the three-litre and minimum weight of 800 kilogrammes formula for that year's Indianapolis 500 and French Grand Prix de l’A.C.F. These team cars were modified by the Sunbeam Experimental department in Wolverhampton for the 1922 Isle of Man Tourist Trophy, which was won by one of the cars. A few months later, and with 1916 4.9-litre engines, two of the T.T. cars competed in the Coppa Florio, Sicily and gained second and fourth position.
