Big engines, quote your MPG here

Voodoomelon · 08-12-2009 07:59PM #1

Well the purpose of this thread is to see how "uneconomical" big engines cars actually are. Everyone mouths off about jeeps, SUVs and large saloons drinking the juice, when in fact I find they are not far off the consumption of underpowered Paddywagons, obviously depending on how large you go.

I'd be interested to see what other large-engined cars are doing MPG wise. Most cars on the road and peoples heads are still working off MPG, so we'll stick to MPG. You can quote your urban/extra urban/average figures if you like, engines 2.5l+ would be preferable.

2000 728i, 2.8l petrol.

I do 90% city driving and average 21MPG. On the motorway I see 36MPG. A 500 mile round trip to Galway I got 31MPG with 4 people and luggage.

What are you getting?

My motorhome: 2.5 liter TD powering a 3.5 ton shed on wheels ...between 10 and 13 l/100 km

Edit: that would be 28 or 22 of those imperial measures of distance to the imperial measure of volume for the old fashioned among us

This will work better if everybody uses the same measurement.

E34 BMW 530i 3.0l V8 auto - commute into Dublin city centre. Mainly Dublin driving + regular longer trips: 20MPG

E38 BMW 735i 3.5l V8 auto - no commute into city centre. Mainly Dublin driving + infrequent longer trips: 21MPG

Porsche 928 4.7l V8 auto - mixed driving: 20MPG

Rover 75 1.8l manual - mixed driving, lots of short trips: 28MPG

More proof for your point, Voodoomelon

BArra · 08-12-2009 08:24PM

2.5ltr turbo ST

35mpg on a long run

average 25mpg

can get under 20 though but its like throwing euro's out the window

Big Nasty · 08-12-2009 08:24PM

BMW 523 E39 2.5L about 25mpg - mostly city driving and the odd long distance haul.

Pontiac Firebird T/A 6.6L about 16mpg motorway, way less if I'm just tooling around!

Seth Brundle · 08-12-2009 08:41PM

Car: E39 523i 2.5L
Consumption: don't really know and don't really care!

squod · 08-12-2009 08:47PM

In before someone quotes me 60mpg for his/her Audi or VAG TDi. I do not believe!

Heroditas · 08-12-2009 08:48PM

E60 523i 2.5L

Quite a mix of city and long trips

City driving: 25MPG

Just drove to Cork today: 36MPG

Average for me: 31MPG

They're both great figures.

Out of interest, what would your average 2004 1.4 litre Astra or Golf get?

bitemybanger · 08-12-2009 09:01PM

2.0 GTi 50 euro gets me from Navan to Rathmines and home again for the week
The oul 6th gear comes in handy on the N3, Low revs=less fuel:)
But if im running a bit late, Ooooh no:(

EPM · 08-12-2009 09:02PM

2006 Leon 1.6.

Best I've seen out of a tank was 37 mpg (my calculations). It will do mid 40's with air con off and driven like a saint.

Average is about 34 mpg to a tank, mostly N and M roads, climate control always on auto, overtaking where possible and usually slightly higher than the speed limit (110 in 100's, 135 in 120's) with cruise on where possible. I blame the low gearing for a lot of it though (3.7k rpm at 120:eek:) but still not a whole lot better compared to the cars mentioned.

Great thread idea btw

No idea! Haven't had a car under 2.5L in......must be 10 years!

An Ard Ri · 08-12-2009 09:07PM

BMW 320ci (E46)

City Driving: 21-22mpg
Motorway Driving (observing the speed limit): 35 mpg
Motorway Driving (belting it): 30 mpg

Rovi · 08-12-2009 09:09PM

2003 Audi RS-6 (4.2l bi-turbo)
Long runs (mostly motorway, cruise set to 80 MPH): 24 MPG
Everyday average (40% town, 40% open road, 20% motorway): 21 MPG
Acting the maggot: mid to low teens
Foot to the floor: 5 MPG

niceirishfella · 08-12-2009 09:12PM

Bmw 535d - avg 33mpg , 25 pushing her on;)

knifey_spoonie · 08-12-2009 09:14PM

Im getting 31 MPG, and thats from a yaris.

Also was getting about 28mpg from a 3.0 D

Dazzy · 08-12-2009 09:15PM

E53 X5 3.0D
Best I ever got was almost 28 MPG, worst was 16MPG after spending 4.5 hours in traffic for what should have been a 20 mins journey because of the snow last year.
Average about 24MPG.

I used to keep a spreadsheet :rolleyes:

Sofiztikated · 08-12-2009 09:17PM

For comparison

my 2003 1.4 focus

Full tank of 55 litres will get me ~400 miles, so 33.3 mpg, thereabouts?

bf · 08-12-2009 09:18PM

2.5 Focus ST

Getting 23.5 mpg on city driving.

Dublin to Limerick today got 34 mpg

ytareh · 08-12-2009 09:23PM

Good idea for a thread .Four wheel drive is probably more of a killer than high cc .Some of the 'souped' up JDM Imprezas/Lancer Evos etc are just beyond funny .(I remember once having a Lancer GSR that I couldnt get to a third day without having to visit a petrol station...)I guess obviously it all depends on how far you drive .If you only drive 'round town' and the odd long spin you can pamper yerself with a gas guzzler but for the commuting classes we need at LEAST 30-35mpg .

Was doin a few 'sums ' on this today as thinking of changing

1 litre Toyota Aygo 52MPG Vs 30mpg sporty wagon Vs 25mpg super sporty wagon = 1625 vs 2815 vs 3375 euro a year .Or to put it another way 135 vs 234 vs 281 euro a month .

Of course there are diesels out there that will do over 60mpg comfortably.
Strange to see that the NEW Cooper Diesel (80mpg+)is now the most economical car as the old one was no great shakes .

Keeping on topic I guess that old 1.6 Lancer GSR 1991 would average 26-28mpg and I like to think I drive fairly 'economically'.By contrast 1989 Opel Kadett GSi 16V would do 40-43 mpg.

SV · 08-12-2009 09:29PM

2litre Clio

Town driving, about 31mpg, motorway driving, about 45-46mpg.

Theanswers · 08-12-2009 09:30PM

Range Rover 2006 3.0 Disiel.

Around town=21mpg.
Not being to easy with the pedal at the lights= 16mpg
Long Trip= 27mpg

Worst i ever got was 6mpg, thats with trailor and foot to the floor.

.Longshanks. · 08-12-2009 09:36PM

I know this thread is mainly for large engine cars, but for comparison my 1.6T corsa has given me a lifetime average of 32.5mpg (according to the trip computer). Never bothered the brim to brim test.

anthony4335 · 08-12-2009 09:43PM

How does everyone do there checks, ie are you using the trip computers or are you doing it by acutal millage vrs consumption.

Mine however not a large engine, IS200 29-30MPG every time I check it.

Voodoomelon · 08-12-2009 09:44PM

Its interesting to note the comparative inefficiencies of small petrol engines, pushing smaller cars. My old 97 Polo had a 1 litre block and I don't think it did any better than 30MPG. The car was incredibly heavy and the engine was so very small.

Newer smaller diesels are of course miles ahead, but when it comes to petrol engines, the big blocks aren't really that much off the smaller ones.

Green Hornet · 08-12-2009 09:45PM

Seeing as there are a few smaller engined cars creeping in here I'll include my Civic 1.8L.

43 mpg - almost all over main road driving and 80 mile round trip/day. Pretty decent for a 1.8L i think?

The Recliner · 08-12-2009 09:57PM

I used to have a Jag XK8, it was a 4L V8 (God I loved that thing)

I was getting around 28mpg out of it, mainly cross country trips

My current RX-8 gets around the same mpg

Matt Simis · 08-12-2009 09:58PM

Both on long trips (everywhere is far away from me) 75km distance, 50% motorway.

BMW 530i 3.0l I6 Auto 28-30mpg (once got 32 on same but cant get back up there)
BMW 850CSI 5.6l V12 6speed Manual 18-21mpg.

Racing around and shorter trips, the 530i is 23mpg and the 850CSI is 15mpg, so the CSI takes less of a hit to economy.

ytareh · 08-12-2009 10:00PM

Jeez Recliner I would have thought the RX8 would have been worse than 28mpg...is it 191 or 231bhp version?Do you recommend them?XK8 must have been nice too !

gpjordanf1 · 08-12-2009 10:07PM

Passat 1.8 Turbo Semi - Auto Tiptronic

Town = 25MPG
Motorway = 36 MPG
Motorway = 30 MPG ( In a hurry! )

Foot to Floor ( 5 - 10 MPG )

Wifes Citroen C4 Van 1.6 Diesel is averaging 65 MPG!
