A car built by JCB has broken the diesel engine land speed record after reaching 328.767mph (529km/h).
A JCB Dieselmax spokesman said the vehicle attained the average speed during two runs in Utah, USA.
Confirmation was given on Tuesday by the Federation Internationale de l'Automobile. An attempt to better the record will be made on Wednesday.
The Staffordshire-built vehicle was driven by Wing Cmdr Andy Green from RAF Wittering in Cambridgeshire.
