One of the vehicles in Scania's new truck range on the road

Scania is introducing a new truck range after 10 years of development work.

Investments in the region of £1.8bn and 10m kilometres of test driving has made this the biggest venture in Scania’s 125-year history, the Swedish firm says.

Production of the truck will start immediately at Scania’s final assembly plant in Södertälje.

Initially, the focus will be on vehicles for long-haul transportation, but additional options will be continually introduced as more Scania plants readjust.

The most noticeable features are the new cabs, but underneath is a 5% reduction in fuel consumption, thanks to factors such as improved powertrains and better aerodynamics.
