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.
