I see the Streetdeck more as a non stop start B5LH which I would class as a no go for the X21. If GNE wanted to save fuel on the X21 whilst not losing performance, ADL (I think), offer the standard E400MMC with a retrofit from GKN, who are doing the Fab 56 and Cobalt Clipper B9s.(21 Aug 2015, 9:10 pm)Malarkey wrote Had a little ride on the StreetDeck earlier from Eldon Square to Gateshead and was not all that impressed by it if I am honest, was quite slow and rattled a hell of a lot on this short trip, think the E400MMC is way better so I do hope that GNE Purchase these instead, On the flipside of the coin, I think the StreetDeck would be a lot better if it was fitted with the Micro-Hybrid Engine which the Streetlites have on the Red Kite etc, and set up to be the same as them performance wise so it could handle the route better.
Theres no Micro Hybrid Engine, Micro Hybrid is a system added to the bus when manufactured.
The 63 Plate Streetlites have the same 5.4 Litre Cummins ISB4 engine as in the Micro Hybrid Streetlites.
Bar the few 57 plates which got in the wrong hands in their early years, most of the E400s are still going strong for Arriva. The E400 MMC would last a good 7 years on most demanding routes if in good hands. I don't think the Streetdeck will and if GNE go for the Streetdeck, all they'll end up doing is 'downgrading' (technically upgrading) the service with older and more reliable B9's. The only 2x routes I could see handling a Streetdeck in terms of reliability (technical and punctuality wise) would be the 309 / 310. Any others would be a big no no.
It would make perfect sense for GNE to ditch Wrights and move to ADL. The E200 MMC seems like a Streetlite but probably far better and they'd also have the option of a Heavyweight powertrain / chassis for the TTX.
