	Early in World War I, Napier was contracted to build engines from other companies' designs: initially a V12 ~~[[Royal Aircraft Establishment\|~~Royal Aircraft Factory]] model and then [[Sunbeam Arab]]s. Both proved to be rather unreliable, and in 1916 Napier decided to design their own instead, an effort that led to the superb W-block 12-cylinder [[Napier Lion\|Lion]]. The Lion was a best-seller for the company, and they eventually dropped all the other aero-engines. The Lion went on to be used in the 1920s to win the [[World Land Speed Record]] in [[Malcolm Campbell]]'s Bluebird and [[Henry Segrave]]'s Golden Arrow.

However, even better fuel economy could be had by flying a normal [[jet engine]] at much higher altitudes, while existing designs filled the "low end" of the market fairly well.

'''Napier & Son''' was a British engine manufacturer and one of the most important aircraft engine manufacturers in the early to mid 20th Century. Their post-World War I Lion was the most powerful engine in the world for some time in the 1920s and into the 1930s, and their Sabre design of the early 1940s holds the title for the most powerful piston aircraft engine produced to this day, delivering 3,500 hp (2,600 kW) in its later versions.

==Early History==
David Napier founded the company in Soho, London in 1808, and made a wide variety of products including steam-powered [[printing press|printing presses]] and a [[centrifuge]] for [[sugar]] manufacturing. They moved to [[Lambeth]], South London in 1830. After his father's death in 1873, his son James Napier specialised in beautifully crafted precision machinery for making [[coin]]s and printing stamps and banknotes.

His son Montague Napier inherited the business in 1895 and took on the job of improving the Panhard car of his friend [[Selwyn Edge|S F Edge]]. Edge was sufficiently impressed to encourage Napier to make his own car, agreeing to buy the entire output, and in 1900 the first one appeared. Napiers made the first ever production six cylinder car (at this time painted in olive green), many winning races including the 1902 [[Gordon Bennett Cup in auto racing|Gordon Bennett]] race in France. Famously, in the following year's Gordon Bennett Cup held in Ireland, Napier was first described as wearing [[British racing green]]. Production reached 250 cars in 1903, overwhelming the Lambeth factory, so a move was made to [[Acton]], north west London. By 1907 1200 people were employed (there had been seven in 1895) and were making about 100 cars a year. In 1912 following a dispute with SF Edge, Napier bought Edge's distribution and sales company and production rose to around 700 cars a year with many supplied to the London Taxi trade.

Napiers expanded into marine engines as well, their 1905 boat ''Napier II'' setting the world [[water speed record]] for a mile at almost 30 knots (56 km/h).

==World War I and Interbellum==
Early in World War I, Napier was contracted to build engines from other companies' designs: initially a V12 [[Royal Aircraft Establishment|Royal Aircraft Factory]] model and then [[Sunbeam Arab]]s. Both proved to be rather unreliable, and in 1916 Napier decided to design their own instead, an effort that led to the superb W-block 12-cylinder [[Napier Lion|Lion]]. The Lion was a best-seller for the company, and they eventually dropped all the other aero-engines. The Lion went on to be used in the 1920s to win the [[World Land Speed Record]] in [[Malcolm Campbell]]'s Bluebird and [[Henry Segrave]]'s Golden Arrow.

Vehicle production continued and 2,000 trucks and ambulances were supplied to the War Office. Montague Napier's health declined and in 1917 he moved to Cannes, France, but continued to take an active involvement in the company until his death in 1931.

In 1919 civilian car production re-commenced with a 6 L six-cylinder car, the T75. These were very expensive, costing about the same as a [[Rolls-Royce Silver Ghost]] and in the early 1920s sales declined. The last cars were made in 1924. An attempt was made to buy the bankrupt [[Bentley Motors Limited|Bentley]] company in 1931 but Napier was outbid at the last minute by Rolls-Royce. The last vehicle project was a three wheeled tractor-trailer goods vehicle, but rather than produce this themselves they sold it to [[Scammell]] who made several thousand.

In the 1930s the introduction of much larger and more powerful aero-engines from other companies suddenly ended sales of the Lion. Napier quickly started work on newer designs, including the 16-cylinder, 1,000 [[hp]], [[Napier Cub|Cub]], used in the [[Blackburn Cubaroo]] single-engined bomber, and the later 16-cylinder [[Napier Rapier|Rapier]] and 24-cylinder [[Napier Dagger|Dagger]], both air-cooled H-block designs. Neither the Rapier nor the Dagger proved very reliable, due to poor cooling of the rearmost cylinders, and even the Dagger's 1,000 hp (750 kW) was less than its competitors offerings when it shipped.

==Pre-and-World War II==
Starting from scratch, Napiers decided to use the new [[sleeve valve]] design in a much larger [[H engine|H-block]] 24-cylinder engine, soon to be known as the [[Napier Sabre|Sabre]]. Designed under [[Frank Halford]], the engine was very advanced and proved to be difficult to adapt to assembly line efforts, so while the engine was ready for production in 1940, it wasn't until 1944 that production versions were considered reliable. At that point efforts were made to improve it, leading eventually to the Sabre VII delivering 3,500 hp (2,600 kW), making it the most powerful engine in the world, from an engine much smaller than its competition.

They also planned to produce a smaller version of the same basic design as the [[Napier Cutlass|Cutlass]], but work on both was cancelled at the outbreak of [[World War II]].

Napier developed a marine engine from the Lion aero engine, the petrol-driven Sea Lion, which could deliver 500 hp and were used in the [[RAF Rescue Launch|"Whaleback" Air Sea Rescue]] Launches.

During the war (1944) Napier were asked by the [[Royal Navy]] to supply a diesel engine for use in their [[patrol boat]]s, but the Culverin's 720 hp (537 kW) was not nearly enough for their needs. Napier then designed the [[Napier Deltic|Deltic]], essentially three Culverins arranged in a large triangle (deltoid). Considered one of the most complex engine designs of its day, the Deltic was nevertheless very reliable, and was taken into service after the war as a [[locomotive]] powerplant (in [[British Rail]]'s [[British Rail Class 55|Class 55]]) in addition to the [[torpedo boat]]s, [[Minesweeper (ship)|minesweeper]]s and other small naval vessels for which it was designed.

The advantage of this complex design was fuel economy: it had the best [[specific fuel consumption]] of any aircraft engine, even to this day.

Smaller models, the 3,000hp-class [[Napier Eland]] and 1,500hp-class [[Napier Gazelle]] did somewhat better, notably the Gazelle which powered several models of the popular [[Westland Wessex]] helicopter.

Napier was taken over by [[English Electric]] in 1942. Today Napier is no longer in the engine business, with the ending of the Deltic sales in the 1960s they had no new modern designs to offer. They continue on today as a primary supplier of [[turbocharger]]s, which can be found on many engines.
