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.

GM I-4 makes less power and has higher consumption than Hyundai I-4.

GM Turbo I-4 makes less power and has higher consumption than Hyundai Turbo I-4.

Are you looking for sales figures? As far as I know, these models have yet to come out. What a wonky statement you made.

GM also hasn't released new I4s or turbo I4s in the past few years while Hyundai just released new ones. And their 2.0L turbo-I4 has already been pushed past the power levels of Hyundai's. As fast as gas mileage. Comparing mileage of two different engines with one having one less gear(hyundai offers a 6-speed while GM only offered a 5-speed) isn't really fair.

I'd still take the turbo Ecotec any day over a Hyundai. I just would have to buy used since I'm not supporting GMs car sales at the moment.

Actually GM has. The 2.0L (LNF) is new as well as the DI 2.4L (LAF) that is currently be used in the 2010 Equinox. Besides VW/Audi and the Mazdaspeed6, who else had DI engines back in 2006 (MY07)? So who is doing it wrong again?

PS - not directed at you FIT

You said they did IT worse. Since automakers are JUST NOW moving from V6's and replacing them with turbo 4's, how can GM be doing anything worse? Also, which GM 4 cyl's are worse than what? You do know that GM has different 4 cyl's right? And what are they worse at? Post links to actual data that compares what is supposedly worse about GM 4 cyl's. Also, post actual data on how GM's replacement for V6 engines are performing worse than others. Will be waiting for the data. Thanks.

I am genuinely baffled. Did you bother to read the blog?

Did you?


the GM produced Chevy Malibu is the compeditor to the Hyundai Sonata and Kia Optima. In 2012, GM is planning on releasing 2 new 4 cylinder engines for a redesigned Malibu. In 2012, we will know if GM following in Hyundai's footsteps is 'succesful', ie reasonable MPG and power numbers for the Malibu or not.

Reread my post and provide the requested info. Thanks.
