GREENMOT developed and has operated since 2011, an innovative automotive climatic test cell. This test cell has been designed to provide OEMs and Tier 1 suppliers, large and highly repeatable testing conditions.
This repeatability is especially guaranteed by direct mechanical connection (eliminating tire/roller dispersion) and GREENMOT robot driver (eliminating human driver dispersion). This high repeatability also leads to development productivity savings that makes engineers able to directly identify and quantify the impact of any modification on test results.

The automotive test cell can be rent from 1/2 day to several months. The services may include the mandatory or/and necessary instrumentation measurements, if needed.
The applications vary :
- Energy flow mapping
- Engine mapping
- Hybrid powertrain development
- Traction control
PERFORMANCE | EMISSION | CLIMATIC | AUTOMATIC TESTING | ENDURANCE
Results & Repeatability
The control on the instrumentation and the high repeatability of the results allow to reduce the number of tests carried out by campaign.
Use cases
Repeatability <0.1% of vehicle consumption measurements on regulatory cycles.
