There's a catch. You have to be an employee of Hyperion, a Santa Clara, California, based software company:
Under its Drive Clean to Drive Change initiative, Hyperion will reimburse employees US $5,000 for vehicles that achieve 45 miles per gallon or the equivalent of gasoline. [...] The standard also is achievable by fuel-efficient vehicles using technologies such as hybrid, diesel and electric that increasingly are available in most of the countries in which Hyperion does business. [...] “We know we are not necessarily going to change the world through this initiative, but we aim to get people thinking about change,” said [Godfrey] Sullivan [president and chief executive officer of Hyperion]. “Drive Clean to Drive Change is not just a good thing to do. It’s the right thing to do.”
Under the Drive Clean to Drive Change plan, employees who have been with Hyperion for more than a year can apply for the subsidy for one vehicle every four years. Up to 200 employees a year will be funded, on a first-come, first-served basis. A shining example of a "transcommercial" company policy, and definitely good to hear about.
