The R-Car M3e can be used in a wide range of automotive applications requiring medium-class computing, including for example In-Vehicle Infotainment, low-end integrated cockpit, connected gateway, central server.
A 2GHz version (M3e-2G) is also available, providing increased CPU power.
The R-Car M3e(-2G) is fully software-compatible with the R-Car H3e(-2G), so existing software resources can be reused effectively.


  • Compliant with ISO 26262 (ASIL-B) functionality safety standard for automotive
  • Optimized functions and performance enable use in a wide range of applications
  • Compatibility with previous products enables use of the existing ecosystem and access to over 180 R-Car Consortium partners



  • Medium-class automotive computing systems
