AB Volvo’s Volvo Powertrain unit will invest SK375 million ($42.4 million) at its plants in Skoevde, Sweden.

The money will go towards a new line for casting and to modify the machining systems for Volvo’s next-generation heavy truck diesel engine, reports Dow Jones. The investment represents just the first step in Volvo’s preparations for the new engine.

The investment also will double capacity on the new Future Process for Casting (Volvo’s patented casting method) in the foundry to 80,000 cylinder blocks annually.
