The new cell is the 17th installed at the Bedfordshire site, and is now fully operational. It houses test equipment, and has been designed specifically to test premium and performance engines used in light duty vehicles. The new cell allows higher control of test parameters and records results with claimed exceptional accuracy.

The new cell has a modular design to suit future expansion and additional testing capability and has been installed as a standalone building. The cell's flexibility means that it can be used for alternative programmes including hybrid vehicles and future engine technologies, and can be expanded with supplementary emissions test equipment.

Phil Stones, chief engineer – Powertrain, said: "The design of the new cell was important to deliver a high tech facility within a short delivery and installation time frame. The flexible nature of the space means we can incorporate new equipment and update the test procedures to suit existing and upcoming customer requirements. It has been designed with high performance car engines in mind, as the technology continues to develop in order to meet tightening emissions regulations and fuel economy targets."

The cell continued a period of sustained investment across the Millbrook sites. The company bought an existing test facility in Leyland earlier this month.
