Daf changes dimension with its new long haul trucks

Daf is the first manufacturer to launch vehicles with extended cabs for more aerodynamic efficiency, safety and comfort. These XF, XG and XG + models will go into production next October.

The Dutch manufacturer unveiled, via a digital live event, its new generation of XF, XG and XG + long-haul trucks. The three cabins are of an unprecedented kind, that born from the freedom given by the legislator to the manufacturer to be able to increase, at the front or at the rear, the maximum length of heavy goods vehicles in order to improve the aerodynamics, safety and comfort. The marketing of such vehicles has been authorized since September 2020.

Starting from a blank sheet for this project developed in seven years, Daf, after studies on the different possible lengthenings and their ability to make the vehicle heavier and therefore not achieve the desired goal (10% reduction in consumption), finally chose to distribute this lengthening to the front and rear. Thus, the front is lengthened by a maximum of 16 cm, allowing, thanks to a tiny hood, better air flow. To this virtue, the small appendix undoubtedly adds that of aesthetics. The work to optimize the air flow was complete: curved windshield, profiled cabin corners, design of the mirrors, curvature of the pavilions, plate under the cabin… The aspect ratio at the rear is 33 cm in the case XG and XG + cabins, with an external length of 2.69 m, a record for a forward cabin.

New DAF ranges: the XG and XG + target the high end

From this new generation, whose orders are officially open and whose production is due to start in October for tractors and 4 × 2 carriers, the XF model is the entry level. Its cabin is 2.36 m long (2.25 m for the current XF), displays 9.73 m3 of interior volume and allows from 1.90 m to 2.07 m of vertical station. It is located 7.5 cm lower than the current XF cabins (Space Cab and Super Space Cab).

Above this model (whose name is curiously taken from the old generation…), the XG and XG + target the top of the range. They differ in the height of the roof and therefore in the dimensions and interior volumes of their cabs: 2.07 m maximum height and 11.85 m3 for the XG, 2.19 m and 12.50 m3 for the XG +. Integrated into a new dashboard, the digital instrumentation panel (12 inches) is standard, the tactile one in the middle of the dashboard (infotainment) being optional.

On the driveline side, the MX-11 and MX-13 engines have been modified (injectors, cylinder blocks, pistons, liners, etc.) and have been added a new generation of turbochargers and new auxiliaries (oil pump, air compressors , alternator). The exhaust gas aftertreatment system is innovative in its design and position (above the chassis for more efficiency and responsiveness). The latest generation of ZF Traxon robotic boxes is standard.

“Unparalleled vision” for the driver

Thanks to the belt line of the windshield and the wide windows as low as possible, Daf puts forward for the driver “an unequaled vision”, especially if his truck has the option of partially glazed passenger door, such as in some distribution trucks. The same approach has led the brand to equip the passenger seat with a jump seat. Note that as an option, the headrest of this seat can be transformed into a table (a solution initiated by MAN).

Expected equipment, because over the years it has become widespread in high-end trucks: rear vision by cameras. Daf offers it via the Digital Vision option, which replaces the main and wide-angle mirrors with heated cameras mounted on retractable arms. There is even a camera at the front which replaces the docking and vision mirrors in front of the truck (Daf Corner View).
