A vehicle designed to try to break the diesel land speed record will be unveiled on Thursday.
JCB are world-renowned for their earth moving equipment
Staffordshire-based JCB has been working on a machine that will travel at more than 300mph (482kph).
The yellow and black streamlined car is nine metres long (29.5ft) and contains two modified versions of a standard JCB engine.
Later in the summer it will be tested on salt flat in the US to try and break the current record of 235mph (378kph).
The car will be driven by wing commander Andy Green, who set the first supersonic land speed record at 763mph (1227kph) in 1997.
