All STEYR models equipped with the patented high efficiency Selective Catalytic Reduction (HI-eSCR2) fulfill Stage V emission regulations.

This is an evolution of the proven Stage IV solution and delivers class-leading power with no compromise on efficiency. As a result, these machines develop more horsepower with less fuel, are more responsive and reliable – all with the extremely low Stage V emissions levels.

Patented engine technology to achieve the latest emission regulation.

  • No particulate filter
  • No exhaust gas recirculation
  • No additional maintenance
  • No oil deterioration because of exhaust gas recirculation

DOC (Diesel Oxidation Catalyst) helps to quickly warm up the SCR catalyst.

Correct SCR catalyst temperature is important for efficient NO x reduction.
In addition to emission modifications, new improvements deliver the following:

  • Increased productivity
  • Increased power
