2014 Chevrolet Sonic

The 2014 Chevrolet Sonic is a subcompact car that offered two engine options: a 1.8L naturally aspirated inline-4 producing 138 horsepower and 125 lb-ft of torque, and a 1.4L turbocharged inline-4 producing 138 horsepower and 148 lb-ft of torque. Both engines could be paired with either a 5-speed manual or a 6-speed automatic transmission, although the 1.4L turbo was only available with a 6-speed manual. Owners generally appreciate the Sonic’s nimble handling, fuel efficiency, and available features for its class. Common dislikes include a somewhat cramped rear seat and occasional reliability concerns.
