GM confirms 3-cylinder engine, 8-speed automatic for future models

Automaker is betting big on fuel-efficient engines and transmissions -- and it's officially entered the 3-cylinder race.

But the real action -- and where the real money is flowing -- is in traditional yet highly efficient gasoline-powered vehicles.

 

As one example, General Motors said it would invest $332 million to develop more fuel-efficient engines and transmissions. The resources will go into GM plants in Michigan, Ohio and Indiana to support the production of the automaker’s new Ecotec 3-cylinder engine (pictured above), a new V6 engine, a new 8-speed transmission and tooling for an existing 6-speed transmission. GM said this brings the automaker’s total spending on U.S. facilities that develop fuel-efficient powertrains to $1.2 billion dollars since 2009.

 

It also signals not only that GM is entering the race to produce more fuel-efficient vehicles due to increasing consumer demand, but that it's also entering the early stages of a race among three automakers to establish a lead in the 3-cylinder engine arena.

 

In a statement, GM said that $225 million of the $332 million investment it announced will be aimed at the development of 3- and 4-cylinder engines, while $55.7 million will go to development of the current 6-speed transmissions and of a new 8-speed transmission. GM is expected to put some of the first 3-cylinder engines it produces into the 2015 Volt in time for a product refresh.


GM’s new 3-cylinder engines, combined with the company's stated goal of cutting weight in current models by a proposed 15 percent, could help the automaker not only catch up in the 3-banger race but also succeed in capturing the growing ranks of fuel-minded car buyers.


However, GM won't be first to market such an engine. Ford will take the early lead with the 2014 Focus, which will pack a turbocharged 1.0-liter 3-cylinder engine as an option that the company expects will return more than 40 mpg.


BMW is also prepping 1- and 1.5-liter twin-turbo 3-cylinder engines for a  foray into the U.S. market, and we got a quick spin in a prototype with the larger-displacement powerplant just before the New York Auto Show. BMW’s new 3-cylinder will enter the U.S. next year in the BMW i8 plug-in hybrid sports coupe.

Just imagine the fuel economy if these 3-cylinder engines were fueled by DIESEL instead of gasoline!

 

What a shame.

My old '91 Geo Metro had a 1.0L (61 cu.in) aluminum 3 cylinder, so these aren't anything new. Mine got about 52 mpg with a 5 speed manual transmission. Hopefully with direct injection and turbocharging, these will be decent engines. I believe the Chevy Volt uses a turbocharged 3 cylinder to run the onboard generator as well, if I'm not mistaken.

I bought a Chevy Crap (cruze) in Feb 2012.  I got the upgraded LT model with RS package. It had the turbo 1.4L in it.

 

At 600 miles on the odometer, the center console developed a very annoying rattle.  I went to the dealership and they said "oh well.  These cars are known for it and there really isn't a way to fix it."  Google Cruze Center Console Rattle.  At 1200 miles, it had a recall to remove the "drip shield" from the motor put there by the envrionmentalists so that oil would not drip onto the road--it would accumulate and catch a fire.  Removing the drip shield caused the engine to create a loud knocking sound when it was warm (like most engines do) but with the shield gone, it was VERY loud. 

 

I guess you get what you pay for.  An entry level Chev car, built like an entry level Chevrolet.  And with a volt being a glorified Cruze with a $15000 premium for a 40 mile battery range?  No THANK you.

 

And for the great fuel mileage?  What a joke.  My car was rated for 28 / 36.  I could occasionally get 36 on the freeway, but I never got close to 28 around town.   I replace the cruze after 1 year and traded it in on a Subaru Forester, a small SUV with a 2.5L non turbo engine that gets 24 / 32 MPG.

 

And Chevrolet brags about getting 36MPG highway with a 1.8L small car, and I get 32MPG highway with a near 40% larger displacement non-turbo engine in a compact SUV that I can load up with tons of stuff?

 

Back to the drawing board, GM.
