2012 Chevrolet Sonic preview drive (photos)

Two engines are available for the Sonic, a 1.8-liter four cylinder on lower trim cars, and a turbocharged 1.4 liter at higher trims. Shown here is the turbocharged 1.4 liter. Both powerplants produce 138 horsepower, but the turbocharged 1.4-liter generates 148 pound-feet of torque, 23 more than the 1.8 liter. Fuel economy for the turbocharged engine is 29 mpg city and 40 mpg highway, about 5 mpg better than the naturally aspirated engine.
