Setting the industry standard The six-cylinder B6.7 has earned an unrivalled position as the world’s leading midrange engine platform for truck, bus and coach applications. And that’s because no other engine in its class can offer such high levels of performance and durability whilst operating under the most challenging duty cycles. The ability to keep performing under long operating hours, very high annual mileages and the most challenging route terrain comes as standard with the unrivalled B Series.  

Designed and tested based on Inland Waterway customer requirements, the X15 Stage V is certified to the latest emission standard and able to deliver optimum performance and efficiency. This integrated engine and aftertreatment package was developed in-house for key European Inland Waterways applications including bow thrusters and main propulsion.  

The ISL G spark ignited natural gas engine meets 2010 U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission standards.  The engine is based on the 8.9 liter diesel automotive (ISL) platform and shares many installation options with the diesel counterpart.
