David Brown, a wealthy Yorkshire industrialist, bought Aston Martin in 1947 after answering a 'For Sale' advertisement in The Times for a un-named sports car company. Soon after becoming a motor car manufacturer, he also purchased the floundering Lagonda company too. The companies were merged as 'Aston Martin Lagonda' and have been as one ever since. It could be said that 'DB' purchased Aston Martin and Lagonda as something of a hobby in order to go motor racing. The David Brown Corporation was already a huge and successful engineering business with interests in, amongst other things gears, gearboxes and tractors.
In 1948, the Two Litre Sports (retrospectively known as the DB1) was introduced, based on the Atom Prototype and powered by Claude Hill’s 4 cylinder engine but it did not prove popular and only 16 examples were built. Whilst the 2 litre DB1 is sometimes considered overweight and underpowered compared to both pre-war and post-war Astons, this may be a little unfair as in part this could be to due the low octane pool petrol in the UK during the immediate post war period.
