DAF introduces CF85 and XF105 ATe

Fully optimised for maximum efficiency (25/11/2011 DAF Eindhoven)

As part of its ATe (Advanced Transport Efficiency) programme, DAF is introducing special tractor versions of its successful CF85 and XF105 models, the specifications of which have been fully optimised for maximum efficiency and economy, and which therefore have as negligible an impact upon the environment as possible. The new CF85 and XF105 ATe models are available now.

With a view to lowering fuel consumption as far as possible, measures were firstly taken to optimise aerodynamics. One of these is the addition of a complete package of roof spoilers and side fenders, combined with side skirts, which will be supplied on the CF85 and XF105 ATe as standard. Tyres that have a low rolling resistance are also supplied as standard. These come in size 315/70R22.5 to lower the vehicle height and to further decrease air resistance.

In the new CF85 and XF105 ATe models, the12.9-litre PACCAR MX engine is coupled to an AS Tronic automated gearbox with a shifting strategy that is fully optimised for lowering fuel consumption. The driver has the option to shift gears himself at speeds below 30 km/h and when using the MX Engine Brake; in all other situations the electronics decide the ideal shifting moment.

The ATe models have a direct drive driveline with a 2.69:1 reduction in order to achieve optimum fuel efficiency. A version with 2.53:1 reduction is available as an option for lighter use and applications. The ATe models also come with adaptive cruise control, which will help to reduce fuel consumption. The MX Engine Brake, which saves both fuel and load capacity, has been selected as a retarder.

What is more, all CF85 and XF105 ATe models come with DAF EcoDrive driver training*, which permanently reduces actual fuel consumption and CO2 emissions by 3 to 5% on average.

DAF ATe
The new CF85 and XF105 ATe versions form part of the DAF ATe (Advanced Transport Efficiency) programme of the same name, a complete package of intelligent solutions that serve to further reduce fuel consumption and emissions and to further improve the truck's efficiency. Also the engines in ATe models are switched off automatically once they have been idling for five minutes, and the maximum speed ex-factory is limited to 85 instead of 89 km/h to achieve a 2 to 3% reduction in fuel consumption and CO2 emissions. In order to raise the driver's awareness of the importance of low fuel consumption, information on the current and achieved fuel consumption is provided on the central display on the dashboard as standard.

The new CF85 and XF105 ATe come with a 12.9-litre PACCAR MX engine which delivers 340 kW/460 hp with the ultra–clean EEV model, and includes the enhancements that have recently been made to these engines. New pistons and piston rings are being used, resulting in further reductions in internal friction and engine efficiency increases. The fuel injection and oil lubrication systems have been optimised and the engine management system further refined for this purpose. DAF is the first in the truck industry to use encapsulation not only for the turbo charger but also for the exhaust manifold unit. This results in improved air management thanks to the greater efficiency of the turbo. The enhancements to the PACCAR MX engine result in around 3% lower fuel consumption and a reduction in CO2 emissions, depending on the conditions and application.

DAF supplies the 4x2 tractors CF85 and XF105 ATe combined with the spacious Space Cab.
