The NBfL may actually be the only double decker with two staircases in the world that has only 2 axles. Hong Kong buses are mostly 3 axles because of the air conditioning.
Meet the amazing V3

Tfl report an average of 6.74mpg for the prototype vehicles (versus 6.1mpg for the 'normal' hybrids working on route 73). Which means they use less fuel, not more.
Compared with 8mpg for olympians/atlanteans etc.
