- A bigger engine would make the bus too heavy for London. Euro 6 engines are heavier and more advanced.
- Operators like First and Arriva wanted more fuel efficient vehicles particularly the former who weren't willing to pay the expensive fuel costs for a B9TL and switched to ADL.
If GNE were to order this vehicle and it went wrong, the only possible route that I could see the Streetdeck handling would be the 310 (not the 309)
The StreetDecker would be ideal for city work, not good for long distance work like the X21.
In an ideal world you would get the scania 9ltr e400 for the X21.
But if 100 people had to choose between the demos I'd bet 99percent would go for the E400.
