Ok, the credit for qualified hybrid vehicles ended on 12/31/2010 so unfortunately, there is no credit available for the vehicle you purchased on your federal tax return, but your state may offer a tax benefit for your vehicle.
Here is a link regarding the credit and states that may offer a credit for vehicles:
You can deduct personal property taxes paid on your vehicle on your Schedule A, if you itemize deductions on your tax return. You can only deduct the taxes paid on the vehicle if the tax is based on the value of the vehicle and if the tax is imposed on an annual basis.
You may also be able to claim the sales and local taxes paid on your purchase of your new vehicle, either as an addition to your standard deduction or also on Schedule A.
