Be interesting to see if an 80's bus would beat a new Streetdeck on a basic bus route length to length as the 80's buses certainly had a more powerful engine but techs improved with turbos etc so the less power could be better used now. Be an interesting one and wouldn't surprise me if it's very close or the 80's bus actually won.
I can't remember what was operating on the X5 back in 83 (VR perhaps?). Here's the engine spec according to Mike Humble - https://www.aronline.co.uk/the-bus-secti...el-engine/
It would be interesting to compare with what we have now.
Assuming it was a VR, I can't ever remember them being that powerful or having much pull. That's not to say they didn't, but I remember there were vehicles around the same time and since which seemed to handle the express routes with much less stress.
Obviously there's more to it than just engine size. Gearing, vehicle weight etc will all have some impact.
