Morning all,
I'm after some honest feedback with regards to economy city/ country between the 2.7l 4 cyl and the 3.4 V6. I don't expect them to be much different.
Also what is the tacho doing on each at 100kph?

Does anyone know the killowatts for each?

I am leaning towards the V6 but there are some good bargains with the 4 cyl and with SWMBO being the main user and doing short trips might be the better option.
I am also aware from first hand experience that on the highway there isn't alot of differance between the two (unless towing).

Thanks in advance,
Dave

Hi Dave,
A few years (2005) ago I was going from Carnarvon to Exmouth in my auto 4.5 80 series towing a 5.8 m tandem poptop complete with family on board(teens).
I caught up to a 3.4 Prado towing a smaller poptop single axle and passed him(him n wife only). Due to one of the kids call of nature he went by again and I ended up catching him and followed him into Manilya roadhouse. We filled up and I said gidday etc had quick chat and he proceeded to work out his fuel consumption on a calculator. I then asked him to work mine out.
He was somewhat annoyed when he worked out that his Prado had used about 5 ltrs of fuel more for the distance (approx 170 kms) than I had going a touch faster with more load.
The point is that if you tow etc be prepared for heavy consumption. The 80 series was doing about 5 km per ltr at the time doing about 95 to 100 kms an hr. He was doing about 90.

Hi,
I think the 3.4 were 132 kw an about 305 nm.
The 2.7 was 112 kw and about 240 nm.
Maybe a small amount out on tourqe figures but im sure kw right.
Alan.

Hi Alan,
I'm used to petrol cruisers, and economy isn't a huge factor. The prado is quite a bit heavier than the lux and is geared higher than the cruisers are. If the bloke in the prado sat on 110kph he would have had better consumption than you. Well that's how it is between the inlaws 4.0 prado and our 105 cruiser.

We don't tow that often and are prepared for heavy consumption when we do and I very rarely exceed 100kph at anytime.
Dave

Hi Dave,
I understand what your saying via your own experience, I would only add that towing at 110kmph in WA is breaking the law here.
I just put it own to the 3.4 working harder than the bigger motor.
Regards Alan.

The 4l are more econimical then the 3.4 as they are very high geared. Tour boy I have heard the 2.7s are giving head trouble at about 170000ks, often resulting in a new head. Can be prevented by doing tappetts every 40000ks. Their was a post on here regarding this. We have 2.7 2wd utes at work, torquer little units but they are light.
Cheers Pete

Dave,

I have a 3.4 Extra Cab. Have done nearly 95,000ks and averaged 11.95l/100ks. Recently towed a campertrailer on a 3,500ks trip and averaged around 14.21l/100ks. There was a lot of 100kph travel. Hilux + campertrailer loaded would have been about 3,000kgs.

Well when I drove a 3.4L prado I always wondered about the 2.7, cheaper to register, bit better fuel consumption (bout 1 - 2L/100km), but then i heard that as the 2.7 was just a chopped off 100 series 4.5L motor it actually had a quicker take off than the 3.4 and has more torque from idle. For what I needed this sounded in retrospect a better option than the 3.4. Towing, maybe not. Traction, same stuff can be bought. Just depends I spose.

They do bring out a 3.0l Turbo Diesel which may be worth a look at for you...

Thanks for the replies guys,
I'm not at all interested in diesels and haven't been for years.

I do drive a T/D hilux (current model) thru some of the worst roads central Queensland has to offer for up to 700km per day and I definately would not own one or even a V6 in this model. The lack of quality thru not being built in Japan (Thailand) is starting to show with alot of electrical probs and it only has 77,000km on the clock.
I am aware that the last model was also built in Thailand but at least back then they were having a go.

Regards
Dave

Hiya Dave

Your complaint is more common than you may think,Ive heard people back dating to the previous model like mine (made in Japan)
07/04Year..I think there was one more produced then the New Model...
I would have stretched my bucks if it was classed a better vehicle but after talking to a few people over the year i decide this model was it and could not be happier although they (T.D) are very hard to get and at a reasonable price...The V6 are a dime a dozen..


Goodluck

Cheers
