2012 Scion iQ first drive (photos)
At only 1.3 liters, the iQ's engine is also tiny. But it still has four cylinders, and uses variable valve timing to improve efficiency. Its EPA rating is 36 mpg city and 37 mpg highway, while its combined EPA fuel economy of 37 mpg is the highest of any non-hybrid car.
