Neither.  Forward motion begins with the 1500cc gasoline engine stopped 
and the permanent magnet electric motor powered from the 135kg Ni-MH 
battery. .  At higher speeds, the gas engine starts from vehicle motion 
fed back through the variable transmission,  At highway speeds both  
the electric motor and the gas engine power the vehicle.  During 
braking the motor acts as generator and recharges the battery.  Also, 
when the engine is running it can charge the battery as well as help 
with the forward motion.  The engine is optimized to run efficiently at 
a certain RPM, so no variable valve timing apparatus is needed.  The 
variable transmission allows the engine speed to remain semi-constant 
at various road speeds.  Even though the Prius is rated for 60mpg city, 
I averaged 70.3mpg over a distance of 8-miles on hwy 118 when it was 
loaded with trucks sucking me along at about 45mph.  At 55mph on a 
freeway, the Prius gets c. 50mpg.
