General Motors plans to add another engine option, a 2.0L Ecotec turbo four-cylinder, to its 2013-MY Chevrolet Malibu in the fall of 2012. According to GM, the Ecotec 2.0L turbo is SAE-certified at 259 horsepower (193 kW) and 260 lb.-ft. of torque (353 Nm). Its peak torque is sustained from 1,700 to 5,500 rpm and helps produce 0-60 performance in 6.3 seconds. There is no mpg estimate as of this writing.

The standard engine offered with the Chevrolet Malibu, which the manufacturer is calling the Malibu Eco, is the all-new Ecotec 2.5L four-cylinder engine. The Malibu’s Ecotec 2.5L produces an SAE-certified 197 horsepower (147 kW) and 191 lb.-ft. of torque (259 Nm).

For the Malibu Eco, the vehicle comes with eAssist technology, which combines start-stop technology with regenerative braking and a lightweight lithium-ion battery that can provide an electric boost in certain driving conditions, delivering a GM-estimated 25 mpg in the city 37 mpg on the highway.

The Chevrolet Malibu Eco is on sale now, with a suggested retail price of $25,995, including a $760 destination charge. Additional models go on sale this summer, followed by the Malibu Turbo this fall.
