This article does not mention
This article does not mention that the $7500 tax credit is not available on the Prius.. and also that you can use GM card $3500 discount to bring the Volt to more than $3,000 less than the inferior Prius.
The Volt 150 HP motor will out perform the 80 hp Prius motor by a large margin.
Most commuters will be able to drive all electric with much better performance and at much less cost.
Needless to say the Volt is much better looking than the Prius.
