I bet I could get a lot more than you in the avensis.?

I have no doubt you could and I'd say I'd beat the 45mpg from this morning also if I wasn't in a hurry going anywhere.

I had intended to buy a 2 litre 140bhp Mondeo before reading on a lot of UK forums that drivers mpg was 40mpg or lower :0 which put me off it. Maybe the Avensis is in same boat.

Had the car into a Toyota dealer (not where car was purchased) yesterday for minor warranty work (greasing a rattly brake caliper pin) and spoke to owner of dealership about mpg. He said it should be doing 45-48mpg depending on journeys so maybe what I am seeing is not too far off.

I used to average 5.9 (47mpg) in my 2010 Avensis. I got it as low as 4.3 (65MPG) on a run to Sligo and back at 100km/h. I now have a 2011 Verso with the same engine and I struggle to get 7.0l/100km.

I found the display to be spot on in the Avensis - I checked it a few times against a pump and it was always within .1 l/100km

One thing OP - are you doing the conversion manually or with an online calculator? Because 5.4 l/100km = 43MPG (US), but 52MPG (Imperial)

As a matter of interest, does the engine sound the same in the 2011 verso compared to 2010 Avensis?

Reason I ask is a close relation bought a 2010 Avensis diesel about a week after I got my 2011. Both have similar mileage but his is a lot more refined than mine sound wise. Toyota main dealer owner where he purchased his told me when I dropped him to collect car that there is a difference between 2010 and 2011 engines, the latter have more poke and as a result "rattlier". He mentioned injectors etc being different. Could account for the fuel economy difference you notice between the two.

I am manually converting litres to gallons by dividing by 4.54.

Excellent point !

No difference with the Verso - feels and sounds identical. My brother has a 2011 tourer and it's the same. I've had a 2012 loaner from a dealership and it felt 100% the same. The official spec is identical (124 bhp (91kW)/3,600RPM and 310Nm / 1,600-2,200RPM)

Oh, and you can't remap a modern Toyota due to ECU encryption. You can chip them, but make sure you don't buy a cheap one!

Interesting. Mine isn't as smooth (but I couldn't say it sound wrong either) when ticking over but I wouldnt have taken any notice of mine until I heard his. Maybe a good service is required ASAP.

Was yours cold? The make less of a rattle once they have warmed up.

I like the look of the new avensis and would go for a diesel myself maybe, overall would they be a better buy then a 2010 passat tdi or would the passat just have the edge

Leonard Hofstadter · 05-09-2013 11:26PM

My dad has a 10 reg one, and says it can do about 1000 km on a tankful. That would suggest an average fuel consumption of about 51 mpg assuming he fills up when the low fuel light comes on i.e. fills up with about 55 litres.

230km trip this morning on a mix of motorway and National routes reported 45.13mpg as per the onboard computer (16km/L) and I was driving more conservatively than usual and changing up sooner so not a big difference on the figures previously recorded above.

After some local driving (maybe a few 30km trips) during week in Nth of the country I did the return 230km trip yesterday evening and refilled at same pump as earlier this week. On return trip I drove as I "normally" do and did not let current fuel consumption figures etc influence how I drove.

600.8km recorded for 38.27litres when pumped clicked which equates to 44.266mpg by my calculations. 170km of total was Motorway miles so optimum mpg would not be obtained here.

Car average KM/L gauge was reset at the time of both fills this week and was reading 15.6km/L last night = 43.99mpg so it was only 0.276mpg out from my calculated figures.

I think this test proves that the Average KM/L gauge in the car is very accurate so I will use this for some smaller runs which should give me a better indication of mpg in different conditions.

Don't know what to say Leex, I wouldn't have thought the 120 hp would have been underpowered for the Avensis as the 104 h in the Passat which would mean driving it harder making it more inefficient, unless of course you drive it slow then the 104 in the passat might give good economy.

If you want real economy you'd have to start thinking about the 1.3 Opel/Fiat Corsa, Punto

Or the VW Polo Bluemotion 1.2 tdi and the New Clio Diesel, the last two with probably the best potential for 70-80 mg

Even the Golf 1.6 TDI 90-104 HP should give good economy.

Renault quote over 90 mpg on the new Clio Diesel on the extra urban and I think 80 odd on the combined.

That's in the same ballpark as I was getting - I wouldn't be too worried. Your driving style has a huge amount to do with it - a few hypermiling techniques like keeping off the brakes by reading the road ahead and gentle acceleration can make a huge difference (if you have the patience!)

Bloddy hell 44 mpg for a diesel. Im managing 39-41 in my 1.8 Mazda 6 petrol...

leex · 08-09-2013 10:38PM

Assuming my computer is accurate (enough) as per my tests last week I think I am realising that a constant 50-55mpg and sedate driving style in the right gear will obtain close on the advertised mpg on my Avensis but once you hit 60mph or above it drops significantly. Didn't alter my driving style of gearchanges but kept mph lower than normal.

* Did 2 runs of about 20-25km on Friday evening. Slowish traffic - maybe 50mpg and averaged 52mpg on one way. Bit quicker coming back and averaged50mpg on return.

* Did another test today with cruise control on for alot of it at about 55mph for about 10miles when car was warmed up. Reset computer at start of trip. Was as low as 60mpg average at some points with journey average of near 58mpg.

There's no point really resetting the trip computer on a warmed up engine especially.

As I said I could claim over 100-150 mpg in the Prius on some trips but the reality is that if I reset the trip computer after a fill it reads 60-64 mpg at the time to fill up again and that's what I calculate it as by my own calculations.

Your best just to keep track after a fill and do the calculations yourself.

corkgsxr · 09-09-2013 08:19AM

Bit **** on a 2 litre avensis you cant go 60mph or over

The old ones had no bother.

Up until last year I had a 02 avensis with 210k miles and cork to tipp trying to stay at 65-70 (obviously not in citys or small roads) it averaged at 56 mpg

Thanks for all the feedback here guys.

Main purpose of this exercise was to see how change of driving style impacted average mpg of a small sample of miles as a full tank test means it is harder to see where I am going wrong. Similar sample was showing 5mpg less when I got the car. It is a learning exercise for me as I have driven 400,000+ miles in petrols but this is my first diesel car. I understand it is not a representation of what the car is averaging long term over mixed miles.

Continuing my quest to understand best MPG performance I did a 230km work trip this morning, taking 3 hours approx. 80km of this was Motorway. Kept to speed limits on all roads and held back on the overtaking etc. I used cruise control for a lot of this trip on straight stretches. Reset computer at start of trip. It was displaying 5.8L/100km at end of trip = 48.7mpg. Getting nearer to the kind of MPG I would have expected when I purchased car.

Car has a "full" stamped Toyota service history but from what I am seeing advertised on service menus for various mileage intervals that it might not have ever had a fuel filter change or an air filter change. I think I will sort this soon and I'd be hoping it may help economy also.

Whatever about a long trip, just don't reset the trip computer on a warm engine.

Resetting the trip computer on warm engines will always return higher mpg numbers.

This is why the pump tank calculations are the only accurate ones.

Cruise is also not efficient, a steady throttle position is much more fuel efficient, turn on your instant mpg readings and you'ss see this go up and down as cruise maintains your speed.

If you can manage to keep a steady throttle position it will use less fuel but your speed will slow down sometimes, but it's a neat trick but difficult sometimes.

Perhaps a smaller diesel would be worth while if you're doing a lot of work trips, or if they're paying mileage i wouldn't worry about it so much.
