Just to clarify the credit gets reduced but does not disappear right away. It is phased out and reduced first to 50% then 25%.

Section 2. BACKGROUND
Section 30D provides for a credit for certain new qualified plug-in electric drive motor vehicles. The credit is equal to the sum of: (1) $2,500, plus (2) for a vehicle which draws propulsion energy from a battery with at least 5 kilowatt hours of capacity, $417, plus an additional $417 for each kilowatt hour of battery capacity in excess of 5 kilowatt hours. Under § 30D(b)(3), that portion of the credit determined by battery capacity cannot exceed $5,000. Therefore, the total amount of the credit allowed for a vehicle is limited to $7,500. The new qualified plug-in electric drive motor vehicle credit phases out for a manufacturer’s vehicles over the one-year period beginning with the second calendar quarter after the calendar quarter in which at least 200,000 qualifying vehicles manufactured by that manufacturer have been sold for use in the United States (determined on a cumulative basis for sales after December 31, 2009) (“phase-out period”). Qualifying vehicles manufactured by that manufacturer are eligible for 50 percent of the credit if acquired in the first two quarters of the phase-out period and 25 percent of the credit if acquired in the third or fourth quarter of the phase-out period. Vehicles manufactured by that manufacturer are not eligible for a credit if acquired after the phase-out period. After December 31, 2009, a vehicle that qualifies for a credit under § 30 does not qualify for the credit under § 30D
