History of Millbrook
Millbrook takes its name from the nearby village where, in the early 19th century, a flourishing community of Mills nestled around a picturesque brook.
In 1924, construction began on the General Motors Proving Ground in Milford, United States. Millbrook's design was inspired by this site.
In the mid-1960s, Vauxhall and Bedford decided that they needed a proving ground similar to those that General Motors operated in the USA. The company scoured the UK for a suitable site that was both flat and hilly, as hills were needed for testing. Eventually, Millbrook was founded.
Construction work began in April 1968. 2,600,00 cu.yds of earth were moved to sculpt the necessary track features into the existing but barren landscape.
Millbrook officially opened in 1970. For the first 18 years, Vauxhall cars and Bedford trucks, buses and military vehicles consumed the efforts of the small staff team on site.
In 1988 a new company, Millbrook Proving Ground Ltd, was formed to trade independently as a wholly owned subsidiary of Group Lotus.
In 1993 Millbrook was separated from Group Lotus by transferring its shares to GM Holdings UK Ltd. The company continued to flourish as an independently managed business by investing in high technology areas.
Millbrook Group was formed in 2015 when Millbrook acquired Test World, a world leading winter vehicle and tyre testing facility in Finland.
In 2016 Millbrook joined the Test and Measurement business segment of Spectris plc, a leading supplier of productivity-enhancing instrumentation and controls.
In 2017 Millbrook expanded its test capacity with the acquisition of a new site in Leyland, Lancashire. Opening in 1980 as Leyland Technical Centre, the site has an impressive set of facilities to test vehicles across commercial, automotive and off-highway sectors.
2018 saw Millbrook continue to expand globally with the acquisition of Millbrook Revolutionary Engineering; a test service and equipment provider headquartered in the US, with presence in China and Germany.
In 2019, Millbrook opened its Autonomous Village. Built to support the development of connected and autonomous vehicles (CAVs), it consists of 6 purpose-built workshops and access to a private 5G network.
2019 saw huge investments across Millbrook, including its Battery Test Facility, run by Millbrook's REPS software. Millbrook also installed its own EDU test systems at its site in Leyland.
