RE: Arriva North West - Runcorn Depot
Completely different engines mate. Mechanically, the X reg DAF SB120s are Darts, as they have the same gearbox and engine, its just the electrics as well as the blatantly obvious difference in body that spells the 2 apart.
Then once Euro 3 was introduced, Darts and SB120s tended to use 4 cylinder engines compared to the 6 cylinder engines of the Euro 1 and 2 buses.
