    maybe, just maybe, it is because some manufacturers have gone to using what is called a modular engine. Made by a company in China where it is modified according to wants of branding. Same base engine, but then it can be modified by bolting on different heads, oil pans, turbo chargers, etc. Something about that just seems it would not be as good as an engine designed from the ground up to do a specific job. But this is the GM way to save money, buying the cheaper Chinese engine.
    There have been a number of comments concerning the 3.5L versus the foreign 3.6L. The 3.5L usually coupled with AT4 seems to get better mileage than 3.6L with AT6.
    You are looking at Eurotec I4 with AT6 so I really have to wonder what changes are happening there when put in different vehicles. Depending what vehicle it is in, i've noticed differences in the horsepower rating. More so with the 3.6L.
    I have to wonder if EPA pollution targets are involved. But at least, these engines look to be way short of 2015 mileage requirements.

    Hi e_net_rider:

    You make some interesting points. ------ GM is sitting on a "CASH COW" with the Chevrolet Malibu, --- BUT they need to "tweek" the line. ---- The Malibu line should include a two door vehicle in the LTZ model, with a six speed manual trans, or a six speed dual manual trans, (similar to what is in the VW line), that can be shifted automatically, and / or with paddles on the steering wheel. ---- The FOUR CYLINDER engine needs to be refined. While it is adequate for the vehicle, is is NOT an automotive jewel. It DOES NOT compare to the four cylinder Honda engine. The four cylinder should have at least 200 hp and 250 hp with a turbo. ------ The exterior colors need to be improved. Black Cherry, and Dark Green should be included in the "line up." -------- They need to get rid of the Goodyear Tires. Put Michelin tires on the vehicle! The Four Cylinder Vehicle should have dual exhaust with a "slight rumble" in the two door LTZ vehicle.

    Best regards. --------------- Dwayne :shades: ;) :)

    Look around, 2 doors are a thing of the past except in a exclusive way. To redesign the body to meet requirements and start up a special line for 2 doors is too expensive. 2 doors are inconvenient as hell. The doors have to be so much longer to access back seat that you can not open them far enough in parking lots to easily get in or out. And because of all the extra beefing up because of the wide whole it has to fill between the pillars, it is possible the 2 door would weigh more than the four door. Doors start to sag much quicker than two doors and with small body flexing you are likely to get more rattling and poorer sealing around the door. Forget 2 doors in a vehicle of this size.
    No argument in getting rid of GY tires. Any vehicle that comes with them should have a warning placard saying to expect needing changing them prematurely. GY, over the years, has been horrible about early wear, tread separation, and bad in several other ways.
    Are you nuts? why the heck are some wanting a noisy exhaust. Is your mind stuck in the age of a kid when you pushed your toys around and made a noise with your mouth?
    The 09 Malibu I had was very quiet and I appreciated that. The new Regals apparently have answered your wants and I find it annoying. Michelin tires too.
    Gearing is sacraficing mileage. If anything, Malibu could adopt some of the nicer things of the Regal, like surface that are not so hard, a center armrest that works. And the whole GM line should adopt the speed sensitive wipers that was in the Malibu.
    And they need to redesign the AC ducting so it does not blow in your face. You should be able to aim it high enough to go over your head removing the hottest air.
    Paddle shifting/stick, etc., may work in some vehicles, but I've found it near worthless. First it is not like the old modification packages you could buy and install. They could bypass all the valving controls and when you commanded it slammed to the next gear. The GM systems are still computer controlled and have a big delay to make sure you will not damage tranny or engine. And to engine braking, forget it. These days gearing is such that you get little engine braking. Also with small engines there is not enough displacement to effectively brake. I infrequently cross a steep bridge high enough for the largest of container ships. Coming into the city, there is a 25mph exit. If you top the bridge and start down shifting, the engine will rev to 8000RPM and you still need quite a bit of brake to safely maneuver that off loop. With the 3.6L.
    Grow up.

    concur with e net here...I have paddle shifters on an 11 outback.....we bought in Dec 10 and have never once used them...have a sportmatic shifter in my 09 CTS..used it once just to see if it really worked....why would I use it...that is why I bought an automatic!...

    interesting comments on the engine block from China.....I love my 3.5L V6 in my 04 Malibu Maxx...with its AT4....with just under 185K on it...still getting 30-32 on the hwy and 24-26 City on good days!..BTW it came with OEM Bridgestones on it..which were the bottom of their product line....CTS has OEM michelins and the outback has continentals...but I am running Eagle GTs on the Malibu now abeit on 17 inche rims and very happy with them....

    as far as 2 doors....he is spot on...and the malibu is targeted as a mid size entry for a family sedan....if you want two doors and a rumble in the exhaust...get a V-8 Challenger or Mustang!

    thanks pao
    The only logical reason I can think of them putting this on vehicles is that like you, many will try it, and at least learn that using a downshift of the tranny with these newer vehicles does little braking as does the engine with especially small displacement.
    The concept of not having to remove hands from wheel is nice, but better used for other features such as AC, radio, etc control.
    Such mileage, I'm tempted to say liar, but i know some vehicles have done better than these newest. I just can not understand the reason if improving mileage is part of the goal.
    Look at this post. l-economy-remains-the-same/
    Fine if you are looking for more power out of an engine with poor gas mileage in my book. I find the 3.6 as it is adequately powered. Although shifting may seem odd to some and why they have come out with an update that makes mileage even worse to satisfy those who can not learn. Put it to the floor and it will go. I have not, but talked to cop who said he took one to 140MPH. I'm not sure I'd trust the stability at that speed.
    And good luck with your life and those GY. There are very few that have done a good job of lasting without failure of some sort and I'd bet they are harder riding than the previous tire. But maybe because of your high mileage, they might make a fit, even if shortlived, to your well broke in suspension. ;)

    Good Evening e_net_rider:

    QUESTION: ---- Why do you find it necessary to personally attack me for my ideas? ----- I just shared some suggestions with regards to the Malibu Line of GM. Personally, I like the sound of a stock Mustang. I think it has a nice mellow tone! If you do not share my opinion, that is "ok" with me, but please do not tell me to "Grow UP!" ------ And I am NOT "nuts" because I like a mellow sound in the exhaust. ---- My stock V6 Camry has a slight rumble in the dual exhaust. ---- Best regards. -------- Dwayne :shades: ;) :)

    I cant say I have had any problems with GY to be honest...had 18 inch Eagle RS-As on our 06 Solstice...many folks complained they let loose in wet weather or easily hydroplaned...I never found that the case with my driving habit....beleive most let go when the car was pushed into a corner, shifting into a corner..or just simply pushing the car beyond its limit......had 42K on them and probably could have gotten another 10K out of them when we traded it....after 5 years...

    I upgraded the rims on the Maxx to a 17 inch aftermarket running 225/50/17s I beleive if memory serves me....have run thru a set of Avon, BFG, Michelins, and now the GY Eagles...If I had to rate them four in order would be the Michelins (65K), GY (20K so far), BFG (36K) and the Avon (30K) in order of comfort, ride, noise, and life span. I dont push the car so this is mainly a communter (100 miles daily) and weekend errand and hauler....Price wise the Michelins were 200 a tire while the others ran 130-150 each......I see another 20K on the GY at this point with normal tire rotation....usually I do it every 7500 miles or so......

    Im still amazed at the mileage I get from my Maxx....but it gets regular maintenance and fluid changes....Im hoping to get 2 more years out of it for 10 years total..then looking to replace it with who knows what....Im sold on the hatchback.but sadly there are few options available on the market these days.....cheers!
  • My 2011 Malibu LT1 4 cyl routinely gets 35 mpg at 65-70 and it has 2800 miles on it. In contrast, the rental Cruze that everybody loves got 21 on trips around suburban NJ this summer. My Cobalt, knocked by all the magazines, gets routinely 38-41 at highway speeds. I wouldn't have a Cruze if GM gave me one. My secretary is on her 3rd recall with a 2011 Cruze.

    I'm very happy with the Malibu's gas mileage.
  • I FINALLY saw 30 mpg with my '09 LTZ 4 cyl 6A. It was steady state cruising on the interstate with the cruise set at 75 and a tail wind. Before, I've never seen better than 28. Keep in mind, I've had this car since September of '08 and it now has 46K miles on it. Usually, driving around KC (with a fair amount of interstate), I only get around 22 mpg. This is the first GM vehicle (car or truck) I've owned where I could not get the mileage advertised on the Monroney sticker. I wish now I'd bought the V6. The mileage penalty could not have been much and I probably would be happier with the vehicle. I've been thinking about trading this car since before it was even broken in. I'll almost certainly trade it before my '04 Avalanche with 68K. And I probably won't trade it on a Chevy. That's saying something because I own 3 bow-ties and have a good relationship with my dealer.

    I finally reached 30+ mpg in my Malibu. Took 2 trips to a place 65 miles away with a total of 80 miles out of 390 miles being on interstates. The tankful returned 31.65 mpg. I had previously broken 29 driving to work and back, which is 8 miles of interstate and 7 miles city each way.
    tires: 28 psi
    RUG 10% ethanol
    10% a/c use
    8500 miles
    2010 LT1 6 spd I4
    Avg speed since last reset a few months ago: 31 mph

    The car's mileage has steadily climbed from 25.4 mpg for a typical tank spent mostly commuting to work when new, to now at 8000 miles, it is at 29.4 mpg for the same driving. In other words, I am smoking the EPA combined numbers and the car is only getting better as miles go onto it.

    I will be adding 4-6 psi to the tires this weekend and may finish giving it the first coat of wax since I bought it 19 months ago.

    I also am pleased with the 21.3 mpg I just recorded in my '96 Riv on a tank used to run around town. That car has no 4th gear and runs 600 added rpms anytime I'm doing more than 40 mph. 184k miles and no 4th gear since 163k. I spent 5 yrs enjoying 27.5 combined mpg from this car using RUG before losing 4th gear. That's why my expectations from the 1.3 liter smaller Malibu with 2 more gears is to get 30 mpg combined.

    My '01 Silverado has 27k miles on it and the gas mileage is still going up on it. 4X4 ext cab with tow pkg and posi. Hitting about 19 mpg on a 65 mile mostly backroads trip this past month.

    I bought my 2006 Chevy Malibu 3 weeks ago with 55,826 Miles on it, and was moving up in the world from a 2000 Ford Windstar. So I was very happy with the Handling, Acceleration, and comfort I have found with my new to me Chevy Malibu. I have been very happy with the lay out of the car, and how simple it is to Adjust everything to fit me perfectly. I like that I can sit all the way back, and pull the telescopic steering wheel out more towards me. Since I have a screwed up back, I really needed a Car that was comfortable, and this is it!

    I have been really watching my Mileage these last few weeks, because I really wanted to see what is the best way to drive , to get the best gas mileage. I drive quite a bit and mileage is important to me.

    I have found on a 20 Mile highway trip, I scored 44 MPG, Doing 72mph with cruise control! City was anywhere from 21 with A/C to 27 with No Ac and maintaining a somewhat moderate speed. On my very first tank of Gas, I had 372.9 Miles mixed. When I filled up the Tank took 11.8 Gallons, which came out to 31.60 MPG for a Mixed tank. This was way above my expectations! So Far I have 800 Miles on this baby in 3 weeks, and Im only on my 3rd tank of gas. In my minivan I would be putting in my 5th tank right about now, and it was a 22 gallon tank!

    I will be Driving to Topeka Ks on Monday or Tuesday , which is a 80 mile one way trip, with only one Toll Stop. I plan to fill the tank before Leaving and when arriving to see exactly what I get on the highway with Cruise control set.

    I will also be driving to Mexico City , Mexico in the next few months, and I will come back and share my Real World Mileage for both of these trips.

    Congratulations on your Bu -- it's a great car.

    But you didn't tell us if it's LS (4 cyl.), or LT(Z) (6 cyl.) It makes a difference. 31.6 MPG sounds right. 44 MPG is, alas, a fantasy -- don't trust the computer. Fill up and calculate yourself.

    Took a trip saturday on back roads of about 90 miles total. Into a 20 mph headwind and the return home with a 20 mph tailwind. None on interstates. 33 mpg avg for the 90 miles. I get 26 city. Drafting with a tailwind, 44 is possible over a few miles at a time. I have to be happy getting EPA hwy on a non-interstate trip averaging 32-33 mph that included dozens of miles in lower gears.
    2.4 L
    9250 miles
    35 psi in tires
    So far, highest range plus miles driven on a tank has been 532 miles.
  • I just got the car about 1 week ago. It drives very smooth and its very quiet. Its way better then a chevy prism. My car has 91,304 miles on it. Im glad I bought it. I dont see a problem with the car at all.

    32.4 on last tank. About 1/3 on highways, 2/3 city. Rating of 26 combined beat by over 20%.
  • Bought this car in Jun11. Have had it in twice for transmission not shifting into first gear, when
    downshifting in maual mode. This car has never came close to mpg rating, highway or city. Level
    highway with air off, only 28mpg. Dealer says it is within their limits. They replaced some part
    in transmission, but didn't correct the problem. Dealer has stopped working with me on this,
    not sure what to do next.
  • paopao Posts: 1,867
    has the dealer tried to reflash the ECM. there was a previous issue that sounds like yours another poster had.....the dealership reflashed the ECM with the most current settings and it solved the problems
  • Thanks pao, I have an appointment tomorrow and I'll make sure to ask
    them to do a reflash of of the ECM.
