What some of our clients say...

Partnering with Sierra CP allowed us to develop two highly flexible transmission test systems designed to evaluate our innovative powertrain solutions. Future customisation of the rigs was key for us, and continual evolution of the test facility has provided a variety of new testing capabilities. The equipment and service supplied by Sierra CP has been fantastic and we wouldn't hesitate to recommend them.
Oliver Grant MEng CEng
Head of R&D
To support our Mechanical Engineering and Automotive Engineering undergraduate and postgraduate courses we engaged with several suppliers to tender for a new testing facility. Sierra CP were awarded the contract to design, build and fit out 2 new test cells within the footprint of one of our old lecture theatres. Working alongside our engineering and estates team, Sierra CP designed a structure with minimal noise breakout and novel use of space in the plant room area. As well as providing the AC dynamometers and drives, a boost rig and the cell facility services. Our researchers have found that the open nature of Sierra CP’s CADET automation software has enabled them to push the research boundaries within a safe working framework.

Associate Professor of Mechanical Engineering Department of Mechanical & Construction Engineering
Working with Sierra CP over the past 10 years, enabled Gibson Technology to adapt & upgrade our existing test cell technology to meet ever more demanding requirements for accuracy & functionality across our range of engine development & pass-off testing activities. The ability to work with a single supplier for the whole test cell, allows us to focus on our core business activities, safe in the knowledge that we have a comprehensive, yet cost effective, solution to our test systems requirements. I can highly recommend Sierra CP as an effective technology partner.
