The 2012 Hyundai Sonata Hybrid is one of the safest green cars that a parent could invest in for their teenager. The vehicle contains a lithium polymer battery that doesn’t even need to be plugged in. This battery also carries a lifetime warranty. The Sonata Hybrid also boasts an estimated 40 miles per gallon (MPG) on the highway. Parents will also be happy to know that the vehicle also achieved a five star rating for frontal driver, side driver and side rear passenger impact safety. The frontal passenger safety rating achieved four stars; still an admirable rating.
