Replying to: malmouza (Jul 29, 2008 6:10 am) Very good point. I would have to agree with what you said. The highway MPG for 4 cylinder midsize sedans are not that different.

Replying to: malmouza (Jul 29, 2008 6:10 am) I'm talking about a 05 model V6 Malibu that is four years old, wouldn't you think technology would have improved ten fold. Your also talking about the aero dynamics of an 05. And last of all engine displacement, it is important other wise you wouldn't see the V6 getting as good if not better highway gas mileage than any four. The Fit's 109 hp engine is rated at 34 mpg highway and thats suppose to be the best in it's class, a little smaller than the Accord that is rated at 31mpg and has a 177hp engine, I dont think the aerodynamics have to much to say in this matter.   And by far you are not getting 42 mpg with the Accord your lucky if your breaking 35 mpg, I also have an 08 Accord LX-P, that I got when my lease ran out on the Malibu a few months back, I know the mpg difference by my experience with both cars not some numbers from a car magazine.

Replying to: packer3 (Jul 29, 2008 6:06 pm) have to concur with the V6 in the Malibu, rated at 200 HP....my 04 Malibu Maxx averages 26-28 combined.....and 32-34 on the hwy.......I cant see a reason to get a new car at this point....based on the fuel economy and size of the Maxx, despite it having 130K on it.....the scheduled maintenance is less than most imports and far less expensive as well...   running full synthetic....oil changes every 7500 miles, a complete 100K service done... all fluids, plugs, wires, belts replace...two brake jobs (64K and 115K), replaced front rotors on the second, one battery, about to place third set of tires (68K on the current set) and no other repairs required. Insurance is low, property tax is low, and its paid for......

Replying to: packer3 (Jul 29, 2008 6:06 pm) I will have to disagree with you on the aerodynamic. The resistance from the air at high speed is one of the big issue that Car maker and Airplane makers are trying to solve to decrease fuel consumption. An example is the train is designed with less surface resistance so Cd is low, and that is why trains can travel 200 miles on one gallon of diesel, carrying tons of merchandise. If the train travel sideways the air resistance will increase and the train will need hundreds of gallons of diesel to travel 200 miles. The other thing is the car engine technology did not change that much over the years, except for the switch from carburetors to fuel injection to direct injection; the principle is still the same combustion chamber where the air and fuel are mixed and ignited by spark plugs or by high compression for the diesel case. Not that much changed, we increased a little bit the fuel efficiency by not that much. But one thing we did over the years is adding more weight to our cars, by adding more motors for the seats, motors for the moon roof, motors for the windows, motors for mirrors, motors for trunk, motors for rear seats, motors for rear wipers, motors for rear climate control fan, etc. Every motor weight a pound or two or more, and you are wondering why we are not getting a good fuel mileage, get ride of half of those motors and you’ll see a 25% increase in MPG, not counting that all those motors drain the battery of energy needed for the engine to run the computer (ECU), and other electrical systems. There you have it. Replies to this message: packer3 (Jul 30, 2008 3:16 pm) packer3 (Jul 31, 2008 7:36 pm)

Replying to: malmouza (Jul 30, 2008 6:40 am) Nice try but I dont think the air theory seems to be working well with the auto makers.   Though I'm glad to see that Pao's Max is still rolling strong.

Replying to: malmouza (Jul 30, 2008 6:40 am) Right, like this wind train theory, if an electric train was going 200 miles per hour which way would the smoke be blowing.
#190 of 193 2009 Malibu by packer3 Aug 03, 2008 (7:38 am)
What I find amazing or scary is the fact people are buying cars somewhat clue less. I just read the one review for the 2009 Malibu, I didn't understand if the person got the 4cyl or the 6cyl, I don't even think they know. The real stopper is that the person just got the car less than a month ago and already there thinking that the gas mileage will get better after it breaks in.   Here's a news flash, what ever mpg they are getting today is what they are going to get tomorrow and the next day, etc. The sales rep. should get an Oscar for that sell, also I hope he told them to inflate their tires past the mfg's recomendation so there mileage will increase, but not telling them that their tires will wear out faster.   See below article.   Vehicle   2009 Chevrolet Malibu LTZ 4dr Sedan (2.4L 4cyl 6A)   Review   Our Malibu has V6 option. Very good feel with power and handling. Looking forward to after break-in to see true gas mileage. Beautiful auto.

Replying to: packer3 (Aug 03, 2008 7:38 am) Although I haven't noticed much improvement in mileage after break in with GM engines, HyunKia engines are very tight when new and improve steadily in MPG for at least 10-15000 miles.   36 lb. gives better gas mileage than 32 in most cars with no problems with increased tire wear.

Replying to: csandste (Aug 04, 2008 12:11 am) keep in mind 36 lbs goes higher in the heat, one thing you never want to do is to push the tires limitations
#193 of 193 MPG After Break-in by hickoryc Aug 20, 2008 (12:16 pm)
Replying to: packer3 (Aug 03, 2008 7:38 am) My '04 Maxx did not get over 30 MPG on highway until 50,000 miles. Now at 60,000, it has averaged 33 on the highway and 28 mixed. Wife's '08 Civic has been inching up in the MPG category each fillup from 32 to 37. I fully expect it to increase even more. To qualify the statement regarding the Maxx, I previously posted that I added STP (Red can) for the first time at 50,000. On a side note, in June we fully loaded the Maxx for vacation and it still got 33 highway miles out of every gallon, about the same as my solo daily commute.
