GM Korea Co., the South Korean unit of U.S. auto giant General Motors Co., unveiled a refreshed Aveo subcompact with a downsized engine and improved transmission setup Wednesday. The Chevrolet brand car, sold as the Sonic in the United States, is powered by a peppy 1.4-liter gasoline turbo engine rated at 140 ponies and copied from the Aveo Rally Sport car. The engine is designed to reduce turbo lag and can achieve 20.4 kilogram meters of torque in the 3,000-4,500 revolution per minute range.
The outgoing Aveo had a 1.6L mill with an output of 114 horsepower and 15.1 kgm of max torque at 4,000 rpm.
