Believe that as part of the latest Steetdeck order, Wrightbus have agreed to a major re-work programme to the existing Streetdeck batches - which covers both mechanical upgrades and through the continued software upgrades that Go North East are already receiving. This gives the ordered 6cyl Streetdeck a bit more purpose in covering depots where needed.

I guess we'll just have to wait and see how much of an improvement the 6 cylinder will be, but for routes like the 21, the 4 cylinder seems (from a passenger's perspective anyway) more than up to the task.

I just think that the X21 would have been better suited to the 6 speed rather than the 4 speed, the B5TLs have a 4 cylinder with similar power but it doesn't seem to struggle at higher speeds. Although it sounds so much more unrefined than the Streetdecks even at the higher speeds even if it isn't screaming!
