The financial crisis has changed people’s habits regarding cars that are more fuel efficient, so knowing what’s the green car of the year 2010 has a bigger impact than ever — but enough with the intro as I’m sure you already know that Audi A3 TDI has secured that title. Announced by the Green Car Journal, the “luxury car features an impressive EPA estimated 42 mpg on the highway – a 50 percent highway fuel efficiency improvement over the standard gasoline engine A3. Plus, this Audi’s quiet, clean diesel engine delivers loads of low-end torque and a fun-to-drive experience, all with the functionality of a 5-passenger hatchback,” says Ron Cogan.
