4 pot engines are rather lacklustre top-end, and by nature have to work harder than a 6 pot varient; especially in heavy double-deckers. More cylinders = more explosions = more power. You can't change or hideaway from this fact.
A route full of NSL and motorway grade roads on hills screams for extra power, to reduce mechanical strain more than anything else.
I'm of course not saying all 6-pot engines are going to be fast, nor that all 4-pot engines are going to be slow. But it's a lot more uncommon to hear of 6-pot engines putting holes through the blocks, opposed to 4-pot systems, like Streetlites.

Then following on from the conversation on here last week, the first bus I'd taken notice of in the UK since returning, was the Sanders Pulsar.
I find that the X-Lines B5TLs also suffer from the same issue. I'm not sure why the location of the route number needs to be stipulated, so long as it's substantially large and visible. The location should be of a suitable place, to the operator's suitability.
