Replying to: micweb (Jul 21, 2008 4:00 pm) Your pretty much dead on about the city driving for the weight class you spoke about. I've said it a few times on the blog, when I leased my 05 Malibu V6 200 hp straight city driving was 15/16 mpg, straight highway run at 65 mph 37 mpg. mixed 28/30. It still amazes me, thats better than any 4cyl. on the market, even GM's own, they have magic in the bottle and don't evevn know it.

Replying to: packer3 (Jul 21, 2008 6:55 pm) My 3.5 Maxx beats my wife's 4 cylinder Optima by a couple of MPG. Probably 22 v. 20 around town. Most of the difference is probably driving styles, however. Her car is driven for extremely short distances and the average MPH is considerably lower on her DIC. I think the 3.5 'Bu is an exceptionally nice engine for low cost in both maintenance and fuel economy.

Replying to: micweb (Jul 21, 2008 4:00 pm) Does anyone know what is the rpm for a 2008 chevy malibu 4 cylinder when its going 65-70MPH on the freeway? Thanks. Replies to this message: micweb (Jul 22, 2008 10:32 am) mazda6dude (Jul 22, 2008 11:42 am)

Replying to: mazda6dude (Jul 22, 2008 6:19 am) Does the 2008 have the 6 speed or the 4 speed?   I'm interested in the answer too.   Automatics often get the same freeway mileage as manual transmissions because the manufacturer can gear them lower, confident that the automatic will unlock (first) then downshift as necessary for pickup. Manufacturers seem reluctant to gear their manual transmissions for optimal freeway mileage since it would then require a manual downshift to 4th for good pickup on the freeway, and then (apparently) consumers would complain that the vehicle is "gutless." (There seems to be an aversion in some drivers to downshifting when already on the freeway - I don't share that aversion.) Replies to this message: mazda6dude (Jul 22, 2008 11:42 am)

Replying to: micweb (Jul 22, 2008 10:32 am) I'm interested in the 4 cylinder 4-speed automatic. I know the LTZ 4 cylinder comes with the 6-speed automatic.

Replying to: packer3 (Jul 21, 2008 6:55 pm) I do not think is better that any I4 on the market. I get 40 or 42 MPG on the highway at 65MPH with the 08 accord I4 and MT transmission. and I get 25 MPG on stop and go traffic, my average per tank is 33 - 34 MPG which is not bad for a large vehicle. And remember I am not hipper-milling, but I am not crawling like turtle either. To sum it up, there is not a lot of difference in highway mileage between cars, it does not matter the engine displacement, but the only difference is the aerodynamic. Friend of mine drive the Honda Fit, at moderate speed on the highway he gets 36 – 37MPG, I get little better numbers with the Accord. The difference is the cd for both cars is different.

Replying to: malmouza (Jul 29, 2008 5:10 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 5:10 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 5:06 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 5:06 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 2:16 pm) packer3 (Jul 31, 2008 6:36 pm)
