Title: MPG - 3.0 V6 Auto Estate vs 2.2 Saloon Manual.
Post by: tunnie on 12 February 2008, 10:40:50
1998 3.0 V6 Elite Estate 160k miles Vs 2000 (facelift) 2.2 Manual CD 107k miles

Its only been 2 days so far, so not the best comparison, but what do you folk rekon the mpg is compared to my 2.2 manual?

How worse off would i be mpg wise?? on my 9 mile commute, of country roads and short dual carridge way. Engine is not up to temp until 30% of the journey is completed.

i dont know,  but if there isn't that much difference ill be crying in my
coffee i cant remember what James said he got to the gallon but it was a lot more than i thought better than my 2.2 iirc (over a similar distance & road conditions)

i'll wait for a few more poll votes, but the results are interesting  ;)

I drive the 3 Auto Est, her the 2.2 Auto Sal

I get better mpg!  But she is doing little more than a school run at the mo
I get 22-23, she gets 21-22!

I would expect it to be very little if acceleration is kept similar between the two varients.

At the end of the day, the weight is similar (the estate is slightly heavier) and the drag factors are pretty much the same so the energy required to get the car to speed and hold it there are the same also. So the fuel used should be pretty similar.

The V6 has the potential to consume more fuel but, that is down to how you drive it!

Not a fair comparison because we all know that women are digital when it comes to throttle use (full on/full off)  ;D



Lets see if any female members on here take the bait to that one!

Well the answer is.... 1mpg!

Usuall week of commuting in the 2.2 i will see 26mpg, 27 at best.

Have seen 25.8 if i rag the 2.2.

Commuting in the 3.0, the first day it dropped to 24.9, but now its risen  :o :o

To 25.2 mpg  :o :o

Suspect if i spank it, shall get much less but for normal driving its very good, as before, on a 12 mile run to the local scrappy, all coutry roads i got 30.4 mpg

Done the same run in my 2.2, got 32 mpg!

Very true IME.
I always wondered why Mrs. KW's MX 5 struggles to manage 30 MPG until I did quite a bit of driving in it over Christmas and averaged 38 MPG. :-X

Especially in a heavy car, it all depends how you drive it. There is the potential to waste a lot of energy accelerating 1.7 tonnes to speed then stopping it. If you plan ahead in your driving and don't pour energy into accelerating the car only to have to brake 200 yds up the road it makes all the difference.

Interestingly, my Westfield (totally opposite situation. 650kg, manual and cr@p aerodynamics) returns approximately the same fuel consumption regardless of how it's driven (within reason) or in what type of traffic.

As long as you're able to keep up 45 MPH or more in an auto V6 to allow lockup in top gear (increasingly difficult on the roads round here >:() they are pretty good. There are a few more moving parts in a V6 and a bit more weight, some more pumping losses as it'll be more hevily throttled back during cruising. Then again, they're slower revving.  :-/

When I bought mine, I figured that there was so little in the fuel consumption outside the urban cycle that a V6 was a no brainer. It's only really in stop-start urban traffic and short journeys that they suffer.

Definately, which makes things interesting when she drives mine, ROAR, purr, ROAR ROAR, purr

According to pyhsics law weight is the primary factor..

Others are secondary..

Weight for accelerating.....drag factor for cruising as you are no longer accelerating a weight  :y
