Buick Regal GS

The current generation Chevrolet Malibu is available with I4 and V6 engines

The 2011 Kia Optima SX (pictured above) like its Hyundai Sonata relative will only be available with four-cylinder engines
CAFE leads to engine downsizing for GM

Manufacturers are preparing for upcoming CAFE changes which will require corporate fleets to average 34.1 mpg by 2016. As a result, a number of auto manufactures are turning to direct injection, turbocharging, hybrid technology, and full electrics to boost their fleet fuel economy.

General Motors is taking a big step, according to GM Inside News, to improve the fuel economy of its bread and butter midsize sedans. The next generation Chevrolet Malibu (due out as a 2012 model) will reportedly only be available with four-cylinder engines.

The current generation Malibu is available with a four-cylinder base engine and an optional six-cylinder engine like most other midsize sedans on the market. It's likely, however, that the next Malibu will use two new four-cylinder engines featuring direct injection technology -- the base engine will be normally aspirated while the uprated motor will be turbocharged.

GM already uses this approach with the new 2011 Buick Regal. The base Regal is available with a 2.4-liter four-cylinder engine producing 182 hp and 172 lb-ft of torque. An optional 2.0-liter turbo four-cylinder engine producing 220 hp and 258 lb-ft of torque will be made available later in the model year. An even more potent Regal GS will come later next year with an uprated turbo four producing 250+ hp.

Another manufacturer that is going four-cylinder-only is Hyundai (along with its accompanying Kia brand). The 2010 Sonata is currently only available with a 2.4-liter four-cylinder engine (24/35 mpg). The 2011 Sonata will be available with a 2.0-liter turbo four cylinder which outpowers and outgrunts the optional V6s in other midsize sedans while delivering 22 mpg in the city and 34 mpg on the highway. Both powertrains will also make their way into the upcoming 2011 Kia Optima.

Toyota's Camry and Honda's Accord are both due for complete redesigns within the next two years, so it would be interesting to see if they too go for a top to bottom four-cylinder engine lineup.

As for the Mazda 6. It's another failure for Mazda in the U.S. midsize market (just like the previous generation Mazda 6). The Sonata has been killing it in sales and the was actually the number 10 selling vehicle (car or truck) in July.

Hyundai's 6 was known for below average power and below average mileage, but then it was connected to just a 4 speed automatic, which also didn't help.

I know 2 Mazda 6 owners who bother experienced spark plug recession holes filling up with oil and causing spark issues. In both instances the owners sold the cars as opposed to a ridiculous repair bill. My other friend bought a new 323 with a read main seal leak that ruined his clutch. Too often Mazda looks too much like Chevy.

getting 34+ mpg on the highway at 65 mph:

And faster than average rust as well.

The Sonata has been killing it in sales

What does this prove? I'm sure tires that are rated C in traction and mileage outsell A and AA tires on price alone. You think the average person does any significant research buying a car? If they did all those Sonata bulges wouldn't need to be there.

Mazdas don't look all that aggressive, in fact they mostly look like they are smiling at you.

You are basing your aversion of Mazda on 2 examples of anecdotal evidence?

Good. I'll avoid Dodge because my dad's minivan had leaky evap coils, 5 bad belt tensioners, leaky head gaskets after 60k miles, a bad transmission at 33k and other issues.

You think that was a problem? Wow. And a "new" Mazda 323?

I'm not going to say they are as good as Honda, but they are not a Chevy, ever.

Statistically speaking or not I should not have seen any occurrences of such a failure.

I am assuming Chevy has gotten better since my last one 30 years ago, which had more problems and recalls than all my prior Chevies (about 7 of them) combined.
