(March 8, 2012) DETROIT — The all-new Ecotec 2.5-liter debuting on the 2013 Chevrolet Malibu midsize sedan this summer is one of the most-powerful naturally aspirated four-cylinder engines in the midsize segment, topping the output from the new Ford Fusion and Toyota Camry.

It will be joined this fall by a new Ecotec 2.0-liter turbo engine, delivering more horsepower than any previous V-6 offered in a Malibu.

Malibu’s Ecotec 2.5L delivers an SAE-certified 197 horsepower and 191 pound-feet of torque — the most torque of any naturally aspirated four-cylinder in the segment. And when compared with the competition, it delivers 19 more horsepower and 21 more lb.-ft. of torque than the 2012 Toyota Camry LE’s 2.5L I4 engine, and 27 more horsepower and 21 more lb.-ft. than the 2013 Ford Fusion’s 2.5L four-cylinder.

The Ecotec 2.0-liter turbo is SAE-certified at 259 horsepower and 260 lb.-ft. of torque. Its peak torque is sustained from 1,700 to 5,500 rpm — a broad range that provides an immediate feeling of power in all driving conditions and helps produce 0-60 performance in 6.3 seconds.

The new engines feature direct injection for increased fuel efficiency and higher power, and help drive Malibu’s performance around the world. Both will be offered in the United States, Canada, Israel and other markets,  while rounding out a diverse North American powertrain lineup that also includes the segment-exclusive, fuel-saving eAssist technology in the Malibu Eco.

It combines start-stop technology with regenerative braking and a lightweight lithium-ion battery to provide an electric boost in certain conditions, delivering a GM-estimated 25 mpg in the city 37 mpg on the highway. That’s better fuel economy than any non-hybrid midsize sedan currently available.
