DAF DRIVELINES GET MAJOR EFFICIENCY BOOST

The DAF drivelines in the truck manufacturer’s range of LF distribution trucks have been given a makeover. 

As a result, they offer an increase in fuel efficiency of up to 7% compared with the current model.

The 7% saving in fuel efficiency is dependant on application.

Main changes relate to the PACCAR PX-5 and PX-7 engines and also the introduction of the company’s 8-Speed PowerLine gearboxes. 

Therefore, both of the DAF drivelines have been completely redesigned.

The engine duo use a new lightweight but strong, compacted graphite iron (CGI) block. 

In addition, a cast-iron cylinder head is used, along with new low-friction pistons.

Completing the spec are new efficient compressors and a new waste-gate turbo.

In total, the new PACCAR PX engines for the DAF LF series are available in seven output ratings.

This spread allows the distribution truck range to meet all customer requirements.

PACCAR’s 4.5-litre PX-5 engine is available with outputs from 170hp to 210hp.

Meanwhile, the larger, 6.7-litre PX-7 has options from 230hp to 310hp. 

The engines develop peak torque at even lower engine speeds, therefore supporting down-speeding and the improved fuel efficiency.

Continuing, the new DAF driveline in the LF has a new 8-speed, fully automatic PowerLine transmission, which features optimal gear spread and steps. 

Powershifting without any torque interruption, for example, enables smooth shifts and quick throttle response.

The result is improved comfort and driveability. 

In addition, the new transmissions provide outstanding low speed manoeuverability. These characteristics are enabled by an ‘urge-to-move’ feature upon releasing the brake pedal. 

Alongside the 8-speed transmission, 6- and 9-speed gearboxes remain available for the DAF LF series. 

Furthermore, fully automatic Allison gearboxes will also be an option for special applications, such as refuse collection and firefighting.
