Volt's fuel efficiency in the city would be four times more than the popular Toyota Prius hybrid, the most efficient car now sold in the U.S. If drivers operate the Volt for less than 40 miles, in theory, they could do so without using a drop of gasoline.
Such gains usually cannot come from optimizing, they are the result of some fundamental Design changes.
Unlike the Prius and other traditional hybrids, the Volt is powered by an ELECTRIC MOTOR and a battery pack with a 40-mile range. After that, a small internal combustion engine kicks in to generate electricity for a total range of 300 miles.
Hybrids like Toyota's Prius on the other hand use a small INTERNAL COMBUSTION ENGINE combined with a high-powered battery to boost fuel efficiency.

Use of the electric motor as the prime driver probably reduces the number of moving parts as the power can be transmitted over the wire (instead of a mechanical power train) resulting in considerable savings on moving parts that are not really needed to move the vehicle around.
