Scania is adding another alternative to its engine lineup with a 100% biodiesel (EN 14214) configuration of a 16-liter, 580 hp (433 kW) V8 engine in the R-series. Today, Scania notes, biodiesel is probably the most uncomplicated solution from a user perspective for reducing the effects on the environment from heavy trucks.
Scania now has five different engines for biodiesel operation in its range, with a power span of 320-580 hp (238 kW to 433 kW). In October 2013, Scania introduced its five-cylinder, 9-liter biodiesel engine in 320 hp (238 kW) and 360 hp (268 kW) versions. These were followed by the 13-liter, inline six engine in 450 hp (336 kW) and 490 hp (365 kW) versions with SCR and EGR aftertreatment systems.
The new 16-liter V8 engine meets Euro 6 requirements with EGR (exhaust gas recirculation) and water-cooled SCR (selective catalytic reduction) aftertreatment. In its basic configuration the new addition offers 2,950 N·m (2,176 lb-ft) from 1,000 r/min.
The Scania Euro 6 V8 engines feature Scania VGT (variable-geometry turbocharger) as well as the Scania XPI (extra-high pressure injection) fuel injection system. This system enables injections independently of camshaft position, as well as multiple injections. The result is better fuel efficiency and emission control.

No other manufacturer has managed to develop five biodiesel engines configured for Euro 6. We are unique in having a biodiesel engine to fit any customer, regardless of the application they plan to run with their vehicle. The fact that we can now offer a V8 to customers with demanding assignments and access to biodiesel is gratifying, and proof of how Scania’s modular design philosophy provides customers with added value, even for environmental considerations.—Joel Granath, vice president for product management at Scania Trucks
According to Scania’s calculations, the engine doesn’t lose more than 8% of its power when it runs on 100% biodiesel fuel. At the same time, there is a minor increase in consumption of fuel and the AdBlue used by the SCR system.
The power loss is manageable if one takes into account that few truck engines are as powerful, even when running on diesel. And what one loses in strength is won back on the sustainability side. Exactly how much depend on how the fuel has been produced. But there is biodiesel fuel on the market that reduces CO2 emissions by up to 80%. And if there are additional cost benefits, such as lower taxes, then biodiesel is a very attractive alternative for many customers.—Joel Granath
Biodiesel is also completely blendable in all proportions with ordinary diesel if biodiesel availability should be limited. In addition, every one of Scania’s diesel engines configured for Euro 6 can be run with 10% biodiesel added, without having to make any particular adjustments.
The Volkswagen Group has been invested in Scania since 2000 and today indirectly and directly holds a total of 89.2% of the voting rights and 62.6% of the capital of the Swedish commercial vehicles company. In February, Volkswagen made a $9.2-billion offer to acquire the remaining shares of the company. (Earlier post.) Scania management at this point has recommended against the offer, saying it undervalues Scania.
