The 2008 Scion xD uses a larger 1.8-liter four-cylinder that makes 128 horsepower, giving the car sufficient power to accelerate briskly in suburban driving. A five-speed manual and four-speed automatic transmission are offered, with the manual returning EPA-estimated gas mileage of 27/33 mpg and the automatic delivering 26/32 mpg (using the more severe EPA testing procedures that go into effect beginning with 2008 Scion xD models).
