Among subcompacts, the Sonic feels almost grown-up. It's reasonably quiet and has a relatively comfortable ride compared to its peers in this spartan class. Handling is responsive and secure, and braking performance is excellent, but the car is far from being fun to drive.
We tested a sedan with the base 1.8-liter engine and automatic, and a hatchback version with the turbocharged 1.4-liter four-cylinder and a six-speed manual. Both produce the same 138 hp, but the turbo 1.4 feels more relaxed and proved quicker accelerating to 60 mph on our track. And both need lots of downshifting to maintain speed on hills. The automatic is a little hesitant, and the six-speed manual, with its long throws, feels balky.
We averaged 30 mpg overall, which doesn't seem too bad until you consider the much larger Honda Accord does the same. We preferred the six-speed automatic paired with the non-turbo base engine despite its unimpressive 28 mpg, which is way behind its direct competitors such as the Honda Fit.
Access is easy, but the front seats aren't all that supportive and the rear is tight. Cargo flexibility is improved with the hatchback, but the sedan has more trunk space and a better view out. A sporty RS hatchback is also available, with leather seats and steering wheel, and a sports suspension. Forward collision and lane-departure warning systems are available, which are unusually advanced safety systems for this class.
