Fitting low-profile tyres (315/45/R22.5) and adapting the air suspension has enabled the fifth wheel height to be reduced from 96 to just 91 centimetres. This means that, within the maximum vehicle height of 4 metres, trailers with an internal height of 3.00 metres can be used, allowing volumes of more than 100 m3 for maximum transport efficiency. An internal height of 3.00 metres is also valuable for transport operators working in the automotive sector where one-metre high standardised containers are often used. These one-meter containers can be stacked three high in the semi-trailer.
The new DAF CF and XF Low Deck tractors are available with air suspension on the front axle. In addition, a new single-leaf parabolic suspension has been developed. A new roof deflector for the XF Low Deck with Super Space Cab ensures optimum aerodynamics and a 1.5% saving in terms of fuel and CO2 emissions. The new DAF Low Deck tractors are available with a wheel base of 3.60 and 3.80 metres and are powered by the state-of-the-art 10.8 litre PACCAR MX-11 and 12.9 litre PACCAR MX-13 engines.
