It would’ve been yeah. Mind, they’d have had to find a lot more room for the increase in batteries needed to make it a full EV.

If you search YouTube for ‘Vantage Power London Bus’ you should find videos of Gemini1’s and a President which were fitted with Vantage Power diesel-electric hybrid systems.
Apart from the 3 or 4 vehicles trialled Im not aware of any others that were done however.
Maybe it was too expensive or they didn’t have any uptake. Certainly weird watching/hearing an old Gemini1 and President pulling away almost silently. I quite liked the sound of the diesel suddenly starting back up. It almost sounded like it took a couple of turns for it to fire back up. Odd but kinda cool.
