Scania Introduces G38 Gearbox Paired With 770hp V8

Swedish commercial vehicle major Scania is introducing its latest iteration of the G-series gearboxes for Scania Opticruise. 

The latest G38 it says is specially developed for working together with Scania’s most powerful V8, the 3,700 Nm, 16 litre 770 hp top-of-the-line engine, which provides superior fuel and weight savings along with a smooth ride and great startability.

Scania states that the G38 is explicitly developed for working in pair with Scania’s 770 hp V8 and is able to handle 3,800 Nm. The G38 is the latest and final iteration of the G-series gearboxes that was first introduced in 2019 (with the G33). It is tailor-made for handling the massive torque that Scania’s 770 hp V8 is producing. Despite being able to handle up to 3,800 Nm of torque, it features exactly the same dimensions and weight as the G33. 

Mats Henriksson, Development Engineer at Scania R&D said, “It is basically about metallurgy, choosing more extreme steel qualities and applying technologies such as cog polishing and shot peening for increasing the hardening and the durability of certain vital components. We have also added extra oil channels for the most crucial parts, but that is all – the basic design of the G-series is very sturdy in itself.”    

As per the company the G-series gearboxes are usually 60-70 kg lighter than the gearboxes they replace, mainly due to the all-aluminium housings and smaller overall dimensions.
