In a surprise to many observers, Toyota formally announced the new Prius Plug-in model will be priced starting at $32,760, well above the price the auto maker had initially signaled. A fully loaded version of the Prius Plug-in will sell for $40,285. The Prius selling price is still about $7,000 less than Chevrolet Volt, but Volt will qualify for a full $7,500 tax credit under the federal government’s incentive program, while the new Prius Plug-in will receive only $2500. The smaller incentive reflects the fact that the government program is based on the size of a vehicle’s battery pack.
