General Motors says the Chevrolet Sonic’s fuel-efficient Ecotec 1.4L turbo engine will now be available in either manual or automatic transmission, providing increased torque of turbocharging to drivers of automatic.  The Sonic is built at GM's assembly plant in Orion Township.  “Providing the option of a turbocharged engine to our non-stick driving Chevy customers allows us to offer everyone the thrill and power of a fuel-efficient Ecotec 1.4L powerplant,” said Jim Danahy, vehicle line director and vehicle chief engineer for North American small cars. “Both in the Sonic and Cruze, the engine enables better fuel economy without sacrificing power or performance. It’s really a winning combination,” he said.
 Sonic’s Ecotec 1.4L turbocharged engine and six-speed manual transmission achieved a 0-to-60 mph time of 7.8 seconds, according to independent AMCI testing – faster than the comparable 2012 Ford Fiesta, Honda Fit and Hyundai Accent. The Sonic with the turbo-automatic combination went from 0 to 60 in about eight seconds. “Traditionally, turbocharging was used to enhance the performance of engines, but today it is as much about fuel economy as a 0-to-60 time,” said Bob Benedict, assistant chief engineer for the Ecotec 1.4L engine. “The turbocharger provides high-pressure airflow for high torque to boost the vehicle and give the driver a fun driving experience with improved fuel efficiency.” The 2012 Chevy Sonic Ecotec 1.4L turbo six-speed automatic delivers an EPA-estimated 37 mpg highway and 27 mpg in the city, while the manual gets 40 mpg on the highway and 29 in the city.  By Joseph Szczesny
