What is Integral Powertrain?

Combining in-depth powertrain expertise with a proven track record, Integral Powertrain undertakes key design and development projects supporting OEMs and Tier 1 suppliers in delivering competitive products to market

Integral Powertrain’s team of test specialists, engineers and technicians provide a wealth of expertise in testing to regulations and standards, to client specific requirements and in the development of appropriate test procedures and methods.

Test Facilities

Integral Powertrain’s Emissions & Driveline Test Facility is an independent testing facility capable of providing certified emissions testing for passenger cars to light commercial vehicles.

A recent multi-million pound investment in the Milton Keynes facilities means we now have a compliant vehicle emissions testing facility, based around state of the art Horiba equipment, featuring a high power 4WD dynamometer, the latest emissions analysers, integrated STARS test automation, and a truly unique cold climate control system.

A flexible but professional approach to testing allows our experienced engineers to cover any client testing requirements; from cold climatic RDE development to high speed performance runs, and emissions and fuel economy testing from all global regions.

With 2 vehicle test cells, ambient (temperature controlled soak space for up to 6 vehicles -23° +/- 3°), and cold vehicle soak storage for up to 3 cars (down to -30°C), private customer offices, vehicle workshop and access to Portable Emissions Measurement Systems (PEMS), Integral Powertrain can cater for a wide range of client testing requirements.

These facilities enable test and development activities in controlled, repeatable conditions without the costs, inconvenience and uncertainties of “on-road” testing.

Key features include:

  • Vehicle emissions (legislative and development)
  • Worldwide Harmonised Light Vehicle Test Procedure (WLTP)
  • Federal 40 CFR Part 1066
  • Fuel consumption
  • Vehicle and powertrain control system development
  • OBD and calibration development
  • Performance work
  • Climatic testing
  • Real Driving Emissions (RDE) testing
  • Each test chamber can run tests independently with gasoline or diesel exhaust systems
  • Facilities are available for part or full project and turn-key work
