DAF Components presents new powertrains for coaches and buses

DAF Components has introduced a completely new series of PACCAR MX-11 and PACCAR MX-13 engines for coaches and buses.

The company says the engines deliver low fuel consumption, long service intervals and excellent driveability thanks to high torque at low revs. For the lowest possible CO2 emissions, the new powertrains also run on HVO biodiesel.

The new generation PACCAR MX-11 (with outputs from 220 kW/299 hp up to 330 kW/449 hp) and MX-13 (315 kW/428 hp up to 390 kW/530 hp) engines are based on the power units that were recently introduced by DAF for the successful XD, XF, XG and XG+ truck series.

These engines are now also available for coach and bus applications and made their first appearance at Busworld 2023, held last week in Brussels, Belgium.

DAF says the combustion of the 10.8 litre PACCAR MX-11 and 12.9 litre PACCAR MX-13 engines has been optimised through the use of new injectors, a new cylinder head and block ,and a new design of pistons and liners.

A new generation of efficient turbo chargers is applied for best air management and new air compressors, oil pumps and alternators ensure parasitic losses are reduced to a minimum.

As a result, the new efficient PACCAR MX-11 and MX-13 engines offer low CO2 emissions and excellent performance, according to DAF. Maximum torque has been further increased by 50 to 150 Nm and is already available at 900 rpm.

The new engine brake delivers up to 20 per cent more torque at lower revs, introducing a new industry benchmark. In addition, the engines need a once-a-year service only.

The DAF stand at the Busworld exhibition in Brussels also featured a model of a future electric chassis for compact coaches.

“This chassis is under development and is based on the platform of the zero emission DAF XB Electric city distribution truck”, said Alfred Beuwer, director of DAF Components.

“There is an increasing interest from coach and bus operators for alternative powertrains. Whatever the future of coach and bus transport will look like, DAF Components will continue to offer its customers the ultimate powertrain solutions, tailored to every application.”
