True mpg 1.8 Corolla hybrid 16 inch wheels

[Cbatoday]

Filled the car to 2nd click after being delieved and have done 205 miles and filled up again to 2nd click on the pump

Used 13.41litres so averaged 69.57 mpg which was a combination of motorway and town driving (the onboard computer gave a reading of around 76 mpg)

I think this is really good mpg which I think may increase as the engine loosens. Only done 300 miles total

What are others getting

 

[AndrueC]

I'm amazed and impressed - very well done. The best I've ever calculated is 58 mpg, though I've had the dash showing higher. I thought today's fill up was going to be good as the dash was showing 62.2 but no. 384 miles, 30 litres = 58 mpg. Fairly typical.

I'm intrigued by your results because the best figure I've ever seen was 70 showing on the dash after a 180 mile motorway drive at 60 mph. I don't know what the actual was that time because after some local running around (visiting half a dozen golf courses) the dash was showing 64 and I calculated it at 54 mpg.

It's not even like you live in a flatter part of the country - I live in south Northants and there's not many hills around here. To be honest the kind of figures you quote make me think there's something wrong with my car 😕 Either that or I'm missing a trick somewhere. Although - I have the Excel so it has 18" wheels which I think negatively impacts fuel consumption.

Andrue, you mention Michael doesnt live in a flatter part of the country to you, thus you surprised he doing better then you.  I find in my Prius terrain that has hills in iy fairs better for mpg then flat terrain. Today I done a journey I do twice a week and I know it will get good mpg and it is hilly terrain. If I travel the opposite direction it is a lot flatter and I know I wont get a good mpg. So maybe there is nothing wrong with your car, maybe you expecting a flat terrain to be better for mpg then a hilly one, and maybe the opposite is true. Its a lot of maybe's, who knows.

[Cbatoday]

Most of my driving is on the flat to be honest. I live on the fylde coast. 

[Catlover]

Well there you are....fylde coast flat, northants flat, one area reporting better mpg... could it be down to drivers.

Possibly although I do everything that hypermilers do except for pulse and glide and historically I achieve or exceed manufacturer figures. I think it may be down to the wheel sizes but I have to admit that I'm surprised it has that much impact.

The only accurate way is to fill to brim both times and then do the maths, filling to a click-off of the pump is not accurate enough.

I can’t remember what the problem would be, but read a previous comment on this forum that filling right to the brim can cause a problem to the vehicle system.

i am really keen on lowering fuel used, but not so that I go to “extreme” (IMO) lengths to determine it. I know the computer read out will be flawed, but I happy to go along with that, just deducting x%, and saying that’s it. Life’s too short to be faffing about with “clicks” or “brim to brim”, what about rocking the vehicle vigouresly to get rid of the last air bubble so another 100ml of fuel can be got in, causing an overflow so all figures are then inaccurate. Just drive the car the best way possible with the satisfaction I doing something, albeit very small, to keep the air cleaner, forgetting about the tonnes of emissions that “developing countries” like China and India are pumping into the atmosphere each day, never mind that which the “developed” countries are adding.

Is your model the 1.8 or 2.0 and do you travel with a boot full of stuff all the time

I don't think it could make **that** much difference, but, have you compared your tyre pressure gauge against some others?

I have tried this on quite a few gauges/pumps. The digital ones I have tried are usually very good, or way out if they are bad (very rare).  The analogue ones are a very mixed bag.  My old PCL (Pneumatic Components Limited) brand 'pencil' model is accurate, and always gets good results in magazine tests over the years, but they aren't that widely available any more.

On the Mk2 Auris, the brochure fuel figures for a 15" wheel was 78 mpg (combined) and for 17" wheel it was 72 mpg.  I think the differences between tyres sizes quoted in the Prius gen 3 and gen 4 brochures were slightly bigger (10 mpg?).  The usual caveats apply when talking about the govt. figures, of course. 

I have seen a paper brochure for the Corolla at the dealers, so they do exist now.  (There was nothing when they first launched).  That should make mpg comparisons between wheel sizes a bit easier.

If, by some quirk, the tracking was out, that would impair the mpg slightly.  The check is normally free at tyre specialists, but I had it checked once and was advised of small adjustments required when I had only just had it done somewhere else!

As the mpg figures get higher these small differences make a bigger (numeric) difference, as I'm sure you know.

[AndrueC]

Mine is the 1.8 Excel Hatchback. I do carry my golf gear around with me but that's only 40 kilos, nothing compared to the weight of the vehicle itself. The tyre gauge I use is this one and not all that old. I did have to lower the rear tyre pressures after I got the car because the dealership had pumped them all up to the same value.

I haven't yet found a comparison between models for the Corolla. The Toyota website gives the same information for both:

Fuel Economy - Combined Max WLTP - 57.6 - 62.7

Fuel Economy - Combined Min WLTP - 55.3

So I'm within the range. If that range is for both models and given the variance mentioned for the Auris my figures sound about right. It makes @Cbatoday's figures very impressive, as they exceed the manufacturer's quoted estimates by a large margin.

[Cbatoday]

Just done 87.6 miles today in the cab all town work and returned just over 80mpg according to the display in the car

Will use it until I get to 200 miles again and see what the true figure is at the pump

[AndrueC]

Interesting. It sounds like the Corolla is really optimised for pootling around town then. Most of my driving is on the open road (albeit the commute is restricted to 50 mph for most of its length) with only a mile or two of town driving. And even my town driving is on the outskirts so almost entirely roundabouts. In the morning I often make it pretty much all the way from the M40 to my office (1.7 miles) on electric power without stopping. In the evening it can be a bit more stop/start but rarely actual queued traffic.

But in a typical week I'd estimate 125 miles commuting and another 30 miles travelling to golf courses. Out of all that I probably only spend 10 miles in what could be described as stop/start.

[AndrueC]

Thinking about it driving on the open road ought to require more fuel because you're driving faster. With a traditional ICE only car urban is worse because of all the stop/start traffic and typically short journeys with a cold engine. A hybrid car alleviates a lot of the stop/start issues and if you spend all day doing it then you won't be driving with a cold engine.

 

That's similar to what I mentioned elsewhere in that I wondered how much difference I'd see with a hybrid, because I already do a lot to alleviate the worst excesses of stop/start traffic. But that question at least is answered: Yes, a hybrid (at least Toyota's), does still reduce the amount of fuel I use. It's just not a huge reduction primarily because most of my driving is at highway speeds and in order to keep a vehicle moving at high speed you have to burn a lot of fuel.

Hi, even you are driving mostly motorways hybrid system still helps propel the car and you are always getting efficiency close to a diesel equivalent or even better. Driving in hills it’s not too bad either, because If you do a regular journeys both directions one way you are using more fuel than driving on flat roads but on the other way you may not use at all or just a tiny bit so you are still within the good range overall. My driving is motorways 80% , country lanes 5% and 15% in town, winter times I do 50mpg and in summer over 60mpg. My winter worsen a lot because I keep the car in ready mode sometimes for hours 6-8 hours , for heating and power supply. 

[Cbatoday]

These are my last 2 days of town only driving from 2nd click to 2nd click

The driving is constant and the engine isnt allowed to cool. It is in eco mode and seems to spend most of the time running on electric

These are my figures for 168.7 miles and it used 10.62 litres @ £1.269 per litre

This equates to 72.20 mpg which tells me it's better round town than on fast roads and motorways

[Parts-King]

I have had several 1.8 Hybrids, and all averaged about 58 MPG. I had my new Corolla last Friday and did 200 miles over the weekend, mixed driving, fast A roads and slow 30, 40 50 A roads with limits. The car holds a lot longer in EV mode and that makes for a very good average of 71.5 over those 200 miles, even now, with another hundred miles on the clock, it is still on 70.5 MPG and I don't hang around in the mornings. I am very impressed. The car is lovely to drive, does not rev as loudly as with previous models, steering is so firm and feels sure footed on the road

What model do you have?

[Parts-King]

1.8 Icon Tech 

[Cbatoday]

Mine is the icon tech and my mpg seems to be getting better as I eek the last mpg out of it. I am on a mission to see if I can get to 90 mpg on the dash display 

Today was 87.3mpg over 125 miles

 

[Parts-King]

Thats brilliant. I am still keeping mine on 70 plus even though I am enthusiastic and spirited on my way to work  

[Cbatoday]

I agree that it stays in electric mode longer when accelerating. Also as soon as the petrol motor cuts in I release the accelerator pedal and the petrol engine cuts out and then reapply the accelerator gently and it stays in electric mode

I also use Shell fuel as I believe it is better quality to the supermarkets fuels

Ah. So another with 16" wheels. My Excel is currently claiming 62.4 - the recent warmer weather has helped it a bit - so I think we're just seeing the difference due to that. It's close to what @Gerg quoted as being the 'official' difference with the Auris and Prius.

I agree that it's surprising how far it will go on electric power and with the warmer weather I've been able to go further on sections of road where it wouldn't hold the speed previously.

[bewA]

I must admit this all does sound quite positive for the arrival of my Corolla 1.8 Design (this month if i'm lucky) although i do realise that the Design doesn't have 16" wheels so the economy won't be as good.

Either way i'm quite surprised how much the difference EV mode actually makes from what is being said here given the range on pure EV mode is between 1-2 miles? although i appreciate it doesn't quite work like that.

My last fill up on my Ford (ecosport 1.0) yielded 41'ish uk mpg and my commute is (mixture of town + country/rural) 46 miles a day, 5 days a week, so i'm really interested to see what my mpg's will be!

[NathK]

Hi all, I took delivery of my 2.0L excel last Friday and travelled from the Wirral to Bath and then onto Pembrokeshire with 55 MPG. Its not on par with the MPG that some of you are having with your 1.8 but for a 2.0 its very impressive.  Another thing that is impressive is showing the so called sports cars a clean set of heels, I put the car into sports mode and pull away from them on the motorway with ease.  The car is fantastic I love driving it after having a Peugeot 308 (2014).
