Volvo B9TL D9B260 260BHP:
- Torque = 1100nm @ 1200rpm (900-1500rpm)
Wright Streetdeck Daimler OM934 5.1 231BHP:
- Torque = 900nm @ 1400rpm
Therefore at higher speeds, unless the power delivery was regulated by the setup of the vehicle which means it would be very slow and struggle to keep to time, then the Streetdeck would have to work harder than the B9TL to achieve the required output. Bar the Coast Road between Station Road / Benfield Road, New York Road past the powergrid (if no muppets are doodling along at 30-40mph on an NSL road!), Blyth Road and the Links Road, the Cobalt Clipper doesn't achieve any such great speeds anywhere else bar a few X39 runs and therefore, an economic setup of a Streetdeck would be more than adequate for both the 309 / 310 but not for the X21 and even more so that the Streetdeck would have to work harder to achieve such speeds. Even though the Micro Hybrid technology would make up for the lack of efficiency at 50mph, the benefits would be seen more across an intensive start-stop route rather than an express route. Don't forget that the Streetdeck is limited to 50mph whereas the B9TL could achieve up to 62mph (the legal limit).
