but anyways, if the 3.5L is a V6 (which i believe it is), it more than likely has some sort of cylinder management system. which means it can switch from 6 cylinders to 4 cylinders to 3 cylinders if it's run at the same speed as you mentioned. it's important to realise that the MPG ratings the manufacturers post are ridiculously unrealistic. they perform these tests in controlled environments under ideal conditions (warm weather, little or no wind, straight roads, no uphills or down) or on a dyno. so logically speaking, a 3.5L engine running on only 3 cylinders can be more efficient than a 2.5L engine using 4 cylinders.
in regards to your cruising rpm's of 1200-1500, try to explain this one: my car is more efficient when i cruise at 2200-2500 than 1500rpm. =) |
easy.. ur going faster =P im not sure if the 3.5 has cylinder management...
anyways i reset the fuel consumption thing as i got onto the highway and i drove at 140km/h for 120km with one passenger weighing around 110 or so (im just guessing, she wont tell me lol) and i got 8.8 L/100km.
then i did some city driving for around... id say maybe 20 km? or less with and now im at 9.0L/100km. ill do some more testing tmr or tonight when i go out.. but the numbers seem to be WAYYY off the website listings of 6l/100km for highway and like 8.5 for city =_= |

| haha no man, its cuz my car is manual. it's normal to coast along at 2500 rpm to stay in the power band. ie, 3rd gear at 2500rpm for my car is about 48km/hr. anyways, you see what i mean by the companies exaggerrating about the fuel mileage then? |

| yea i see what you mean... is it possible to get the listed fuel consumption from a start though? or is it one of those things where u start counting at the top of a hill and after u roll down u have like 1L/100km? |

| haha if you were able to find a 100km downhill and roll down it while idling you'd probably make 0.1L/100km!! from what i said previously, i don't think it's possible to get the numbers the manufacturers get; the conditions are far too ideal. |
