Millbrook Proving Ground is an Englishvehicle testing centre located atMillbrook, Bedfordshire. One of the largest vehicle testing centres in Europe, it is near to theM1 andBedford.
Modelled on theMilford Proving Ground operated byGeneral Motors (GM) inMichigan, Millbrook was opened in the 1960s by the GM subsidiaryBedford before passing over toVauxhall. Due to the geographical needs of a full testing centre, including both hills and flat land, the traditional choice of a formerRoyal Air Force airfield was ruled out and many sites around the UK were surveyed before the location atMillbrook was decided upon, especially due to having the benefit of being close to Vauxhall's production site atLuton.[1]
Construction of the Proving Ground began in 1968, and once the facility opened in 1970 it acted as the testing site for many European GM models from, among others, the Vauxhall and Bedford companies.
With Bedford withdrawing from the bus and truck markets in December 1986, Millbrook was put up for sale by GM.[2] In 1988 the site was transferred to a new company, Millbrook Proving Ground Limited as part ofLotus and offered its facilities to non-GM companies. With the sale of Lotus in 1993 Millbrook was transferred to GM Holdings UK Limited, as an independently managed company which diversified into all aspects of vehicle testing includingemission control.[1] In October 2013, the proving ground was purchased by Rutland Partners.[3] In September 2016 it was sold toSpectris.[4] In December 2020 it was announced that Millbrook would be divested from the Spectris portfolio of companies and acquired by UTAC CERAM for £133 million.[5] The divestment was completed on the 2 February 2021.[6]
