2. Chevrolet Spark: 1.2L (1,249 cc)
Chevrolet’s new city car, the Spark, features an even smaller engine than the iQ and Insight. The new 1.2L EcoTec engine makes 83-hp and when paired to a five-speed manual transmission earns an EPA rated 32/38 mpg city/highway. That’s not bad at all for a car that starts a $12,245.
