PHEV drivetrain with a 50 mile all electric range: would handle virtually all of the situations. Climbing a steep hill? EV drivetrains don't care and provide great torque. Start/stop? perfect. Regenerative braking? There you go. Need all-electric for a spell? Gas to extend range? Gas for AC/Heat? ok ok ok. Smooth operation? Low noise? Low/no emissions? yes yes yes Less wear? Less gas? Lower operating costs? Simpler drivetrains? Simpler repairs? yes to all of it. Every bus should have been forced to be a PHEV drivetrain within a decade of the Prius/Insight being released in 1997. The USPS should have been all PHEV by then too.
