True , and I suppose that will mitigate it somewhat. However
ultimately that engine will produce less power than a normal bus
engine so when relying on the engine alone its going to be slower
compared to the normal engine running at optimum gearing.


Yes, but busses (especially in London) are very stop-start; if the engine
is busy recharging the battery when at a bus stop and/or red lights, it will
mitigate that to some extent.

Plus the regenerative braking, of course.

Exactly how far those effects help is something they will find out
as part of the trial, I guess.
