Millbrook milestone celebrated

Millbrook is celebrating 50 years since its Bedfordshire Proving Ground opened. The company is marking the anniversary by speaking to its alumni and launching a brand new website, despite postponing a full scale celebration.

Millbrook’s operations remain ‘COVID-secure’ and it is continuing to offer practically all of its test services to its customers, while respecting the new rules and minimising risks.

50 years of Millbrook

Millbrook’s Proving Ground in Bedfordshire was opened in 1970 by General Motors as a dedicated testing and development facility for Bedford and Vauxhall. Favoured for having both naturally flat and hilly sections, the Proving Ground took two years to construct. It involved moving nearly 2 million cubic meters of earth, laying more than 100,000 cubic meters of aggregate, hardcore, sand and cement, and planting some 200,000 trees.

In 1988, Millbrook Proving Ground began to trade independently as a wholly owned subsidiary of Group Lotus – itself part of General Motors at the time. This was the start of Millbrook’s role as a highly customer-focused automotive test service provider. It enjoyed steady growth of both customers and capabilities throughout the 1990s and 2000s.

Millbrook expanded in 2015, when the business acquired world-leading winter vehicle and tyre testing facility, Test World, in northern Finland. A year later, Millbrook was acquired by Spectris Group, under whose ownership it continues to thrive.

Millbrook has invested £120 million in its test facilities since 2015. This includes acquiring Detroit-based, EV driveline test system and test service provider, Revolutionary Engineering in 2018, and opening a new Millbrook Revolutionary Engineering site in California in 2019. It also acquired Lancashire-based Leyland Technical Centre in 2017, adding to its physical test capabilities in the UK.

The original Proving Ground in Bedfordshire has enjoyed significant investment in recent years. In 2019 it opened the UK’s most comprehensive independent propulsion systems test, validation and certification facility. It also opened its Battery Test Facility – the UK’s largest private investment in independent battery testing. It became home to the UK’s first 5G network for Connected and Autonomous Vehicles (CAVs) and opened the Autonomous Village to enable the development of CAVs onsite.
