Three engines will be available in the redesigned 2007 Chrysler Sebring sedan: a 2.4-liter four-cylinder, a 2.7-liter V6, and a 3.5-liter V6. The smallest of the three, the so-called World Engine, features variable valve timing, 172 horsepower, and an expected four-percent gain in fuel economy with a four-speed automatic transmission directing power to the front wheels. One notch up is the 2.7-liter V6, offering 190 horsepower and 190 lb.-ft. of torque, again mated to a four-speed automatic. At the top of the food chain is the 3.5-liter V6, boasting 235 horsepower and 232 lb.-ft. of torque, bolted to a new six-speed automatic transmission with Chrysler’s AutoStick manual-mode feature. Available only in Limited trim, the 2007 Sebring’s biggest six-cylinder is expected to produce 0-60 mph times that are among the best in the mid-size sedan class. All engines will be built in either Kenosha, Wisc., or Dundee, Mich., while the Sebring will be assembled in Sterling Heights, Mich.
