The Aster was an English automobile manufactured from 1922 to 1930. The companies car roots can be traced to 1899 when Begbie Manufacturing of Wembley, in north London became British licensees of the French Aster company making mainly stationary engines . In 1913 they became Aster Engineering Co (1913) Ltd and during the First World War made aircraft engines.

The first Aster cars were made in 1922 with the luxurious 18/50, which had a 2618 cc six cylinder overhead valve engine driving the rear wheels through a four speed gearbox. The 126 inch wheelbase chassis had semi elliptic springing at the front and cantilevered springs at the rear with four wheel brakes as an early option. The car was listed at £850 in 1923 and about 50 were made before in 1924 the engine was enlarged to 2890 cc by increasing its bore from 69.5 to 73 mm in the 20/55 model. One was bought by the Duke of York. About another 50 of the larger cars were made. In 1926 the engine was further bored out to 75 mm, the stroke stayed at 115 mm throughout, making the 3042 cc 21/60.

The largest car they made was the 1927 24/70 with a 147 inch wheelbase, a foot longer than the 21/60. The 3042 cc engine for this was created by boring the engine a further 5 mm to 80 mm and fitting Burt-McCollum single sleeve valves which were also fitted to the 21/60 engine from that year. The top of the range 39 cwt Landaulette cost £1300. Probably about 70 were made.

They merged with Arrol-Johnston in 1927 following which production moved to Dumfries, Scotland and the cars became known as Arrol-Asters. The Wembley premises were kept as a service depot eventually being sold to Singer. The 21/60 and 24/70 were kept in production and were joined by a straight eight 2760 cc sleeve valved engine 23/70 and 17/50 six which was also available with Cozette supercharger.

The late 1920s were not a good time for luxury car makers and the receivers arrived in 1929. Limited production continued until 1931 when the factory finally closed
