MAHLE Powertrain invests $4M in US dyno services for EVs


MAHLE Powertrain is investing $4 million in a brand new powertrain dynamometer facility in Plymouth, Michigan, aimed toward accelerating automobile growth as producers proceed the shift in direction of electrified autos.

Able to supporting full powertrain growth, from the testing and calibration of particular person drive elements to the whole driveline methods of advanced four-wheel-drive autos, the brand new facility handles the calls for of even the best efficiency light- and heavy-duty hybrid and electrical autos.


The brand new facility permits Superior Driver Help System (ADAS) know-how assessments, US and European emissions testing functionality, and drivability growth testing all on the identical testbed and might be prepared for operation within the third quarter of 2022.

The brand new services will lengthen our distinctive capabilities to cowl shopper necessities each within the US and globally and can show a useful useful resource for light-duty and heavy-duty producers alike. Crucially, this implies we’re capable of conduct a big quantity of growth and validation work with out requiring numerous prototype autos to be constructed by the producer.

The brand new check facility, positioned at MAHLE Powertrain’s engineering middle in Plymouth, Michigan, will work alongside the present chassis dynamometer and can help all elements of hybrid and battery-electric automobile growth.

By enabling the early evaluation of assorted powertrain layouts and permitting testing to be performed earlier than a accomplished chassis is on the market, the brand new facility will assist producers to shorten the general growth cycle considerably.

In addition to full powertrain testing and calibration work, the power will allow the event of powertrain methods, the calibration of transmissions, hybrid and battery-electric powertrain configurations, Actual Driving Emissions (RDE) measurements and electrical automobile vary willpower.

The testbed may even help the testing and analysis of ADAS applied sciences together with LiDAR and RADAR sensor packs, and can characteristic climatic conditioning all the way down to -10°C or as much as +40°C.

The brand new facility exceeds the specs of the best efficiency electrical autos in the marketplace, with the aptitude of dealing with as much as 7,000 N·m of instantaneous torque per wheel with a mean torque response time of 0.5ms. The dynos are supported by a 623kW battery emulator with future enlargement capability to greater than 1MW. These options coupled with a most wheelbase of 4.5m make the power distinctive in accommodating even the best output pickups and cargo vans.

The brand new facility is predicted to be prepared for operation within the third quarter of 2022.
