Daf has revealed a new generation of XF, XG and XG+ trucks, which will go into production before the end of the year.
The vehicles promise a 10% improvement in fuel efficiency, a full suite of passive and active safety features and the “next level” of luxury in truck design.
Daf says it is the first European truck maker to introduce a new generation of trucks developed using the additional freedom offered by the new European Commission regulations for emissions reduction, road safety and driver comfort.
The new trucks have a 19% improvement in aerodynamics, achieved by the new cab shape and measures taken to realise optimal engine compartment and under cab airflows.
The truck maker's existing PACCAR MX-11 and MX-13 engines feature new injectors, a new cylinder head and block – allowing higher cylinder pressures – and a new design of pistons and liners.
A new generation of efficient turbo chargers is utilised for best air management and new air compressors, oil pumps and alternators ensure parasitic losses are reduced to a minimum. The exhaust-after-treatment system has also been redesigned.
Low vehicle weights and enhanced driver assistance systems bring the total efficiency gain up to 10%, representing the largest fuel efficiency improvement in the history of the company.
Performance is also improved, thanks to torque increases of 50 to 100Nm in direct drive top gear. The top-rated 390kW/530hp version now offers 2,550Nm in every lower gear and 2,700Nm in top gear.
The new vehicles are the first to receive over-the-air-updates for the engine and after-treatment systems, they also have service intervals of up to 124,000 miles or once-a-year.
A new optional feature is the Daf Digital Vision System, replacing the main and wide-angle mirrors. Use of the cameras further enhances direct vision, while also increasing aerodynamic performance, contributing to highest fuel efficiency.
Daf Corner View is an option to replace the kerb and front view mirrors and which exceeds the field of vision of these conventional mirrors by far. The display of the Corner View is mounted on the co-driver’s A-pillar.
New Generation XF
The New Generation XF features a new cab design with a 160mm elongation at the front for improved aerodynamics. It has a 75mm lower cab datum compared to the XF Super Space Cab and Space Cab. In combination with a large windscreen and ultra-low belt line, this results in unmatched direct vision, according to Daf.
Standing height in the new XF is between 1,900 and 2,075mm, depending on the position within the cab.
New Generation XG and XG+
Daf is introducing the XG and XG+, creating a new top-class market segment, which takes maximum benefit from the new masses and dimensions regulations.
Next to the 160mm elongated front, both flagship models feature no less than 330mm extra length at the rear of the cab. The cab datum of the XG and XG+ is 125mm higher than the New Generation XF. The semi-flat floor provides easy access with three steps.
The Daf XG cab interior offers a standing height from no less than 1,980 to 2,105mm.
Daf says the new XG+ “outperforms every truck on the market” when it comes to interior space. The height of the roof is increased even more to offer a standing height of up to 2,220mm. As Daf’s top-of-the-range model, it offers a high level of living comfort and spaciousness.
Daf will start series production of 4x2 and 6x2 tractor and rigid offerings of its new XF, XG and XG+ in the last quarter of 2021.
