Deep in the heart of the Bentley factory in Crewe is a large, airy and air-conditioned workshop that visitors, even out of a government lockdown, will never see. It’s packed with the kind of precision instruments you’d expect to find in a space agency facility or university science lab. It’s here that Head of Metrology Michael Stockdale and his 25 colleagues measure every part of a Bentley to the highest standards of precision.
