The 2010 Ford Fusion Hybrid just got a lot cheaper for potential buyers in the U.S. After being tested by the Environmental Protection Agency its miles per gallon rating of 41 in the city and 36 on the highway qualifies it for the maximum federal tax credit for hybrid vehicles.

This means that Ford Fusion Hybrid buyers will receive $3,400 in tax credits.

But if you’re thinking of joining the ranks of hybrid vehicle owners you won’t want to take too much time in getting yours. Once an car manufacturer sells 60,000 hybrids that tax credit slowly dissolves into vapor.

Ford has already hit its limit and will see its tax credit cut in half this April.
