Fastest Enviro... not being so fast. I love the noise though, it's brilliant piece of machinery! ZF Ecolife 5 speed better than the Voith 4 speed, it's worth kicking down.
Mistake: Its actual a 6 Speed Allison gearbox (*due to a 6th gear maximising fuel economy on motorway runs*) and not a 5 Speed ZF Ecolife. Engine: Cummins ISBe6/Allison 2100 gearbox.
