Our tradition is innovation

There is little point in reinventing the wheel, but a lot to gain by reinventing the vehicle it carries – and this is a wheel that turns faster and faster all the time. The original HESS team was made up mostly of wainwrights and blacksmiths. Today’s team includes IT professionals, automotive electricians, engineers, mechanics, bodywork fitters and finishers, as well as all the other specialized technicians and craftsmen, whose shared decades of expertise and experience continue to drive the company’s name for reliability and innovation towards the future.
