Volvo Trucks’ unique powertrain is now more efficient than ever before. With the latest generation of Euro 6 engines and the integrated intelligent Volvo I-Shift transmission, Volvo Trucks is taking yet another step on the path to efficient transportation. The integrated powertrain consists of an enhanced Euro 6 engine and Volvo’s unique I-Shift. The engine is a perfect example of how several small advances together can result in a big improvement. The two most significant updates are increased compression ratio on the D13 420 and 460 hp versions, and a new optimised turbocharger on the 500 and 540 hp variants of the D13 engine.
