Downsizing opportunity

The high power density and excellent torque in our 1206 range gives machine manufacturers the opportunity to use our 6 cylinder engine instead of a larger engine. Downsizing in this way can save you money and create more space to package new aftertreatment units. The 1206 range is an ideal engine solution for large and medium-sized machines for construction, agriculture, materials handling and general industrial applications.

Easy to switch

The 1206 range features a consistent set of core technologies, supporting your transition from Stage IIIB/Tier 4 Interim to Stage V/Tier 4 Final emission standards which came into force for engines 130-560 kW (175-750 hp) in January 2019. Stage IV/Tier 4 Final emissions standards for engines below 130 kW (175 hp) were introduced in the EU in October 2014 and in the U.S. in January 2015.

Outstanding performance

Like you, we believe there is no need for a trade-off between meeting emission standards and delivering on performance. The 1200 Series tackles the emissions challenge head-on and gives you improved productivity levels and fuel consumption compared to the previous generation Stage IIIB/Tier 4 Interim engines. The powerful 1206 range outperforms the competition with its improved torque of up to 1282 Nm and outstanding transient response, making it the perfect choice for customers looking for reliable power.

Tailored for your machines

Your needs are our top priority, which is why we provide more tailored technology than anyone else. Working closely with OEMs, we have developed the 1206 range with hundreds of variables so that it easily fits into your machine.

Our 1206 range engines come with two year warranties as standard and can also be supported by extended service contracts.

Building on more than 80 years of experience, the 1200 Series benefits from our engineering experience and heritage. Its improved productivity and fuel consumption reduces the total cost of ownership.

1206J-E70TTA Industrial Open Power Unit Standard Equipment
