Power-dense powertrains for Malibu rollout

The all-new Ecotec 2.5L 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. It will be joined this fall by a new Ecotec 2.0L 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 (147 kW) and 191 lb-ft. of torque (259 N·m)—the most torque of any naturally aspirated four-cylinder in the segment. And when compared with the competition, it delivers 19 more horsepower (14 kW) and 21 more lb-ft of torque (28 N·m) than the 2012 Toyota Camry LE’s 2.5L I4 engine, and 27 more horsepower (20 kW) and 21 more lb-ft (28 N·m) than the 2013 Ford Fusion’s 2.5L four-cylinder.

The Ecotec 2.0L turbo is SAE-certified at 259 horsepower (193 kW) and 260 lb-ft of torque (353 N·m). Its peak torque is sustained from 1,700 to 5,500 rpm.

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 eAssist technology in the Malibu Eco. (Earlier post.)

The 2013 Malibu is Chevrolet’s first global midsize sedan and will eventually be sold in nearly 100 countries on six continents. It is already on sale in South Korea and China, with sales to begin this year in more than 70 additional countries, including Canada, throughout Europe, Scandinavia, the Middle East, Africa and other Asia-Pacific markets.



They have no hybrid to compete with Camry, Altima nor Fusion, that is pathetic.

What is the Volt?


The Volt is not mid sized and is an EREV.
I am talking about a mid sized sedan that has been selling well and is offered in a hybrid configuration, not the BAS stuff, but a REAL hybrid.

If they are depending on the Volt to go up against the sales of Camry, Altima and Fusion hybrids, they are kidding themselves. I figured you knew all of this but are just flaming to get a response.


eAssist is not a bad idea.. very low cost if not bundled with other options, less than $800.

It has been reported the new eAssist sedans achieve 30mpg combined in everyday driving.. the new Malibu gets 44mpg while cruising at 70mph on the hwy.

The next step for eAssist is a way to miniaturize the battery, it takes too much room in the trunk. The step after that is to use electric AC compressors so that the engine does not have to run when the AC is on.


"I am talking about a mid sized sedan that has been selling well and is offered in a hybrid configuration, not the BAS stuff, but a REAL hybrid."

A strong hybrid.. the Paige patent for powersplit hybrids runs out this year, but GM could always use a derivative of Voltec with a smaller battery. The expensive part, the software, has already been developed for the Volt.

Can any hybrid manufacturer compete against Toyota?.. the market share does not seem to think so.
