Real mpg

[Trg1244]

Hi, I’ve been looking to see if there is another thread with this question already has been answered.

What real mpg figures are people getting, as in not what the trip computer is telling you, but how many miles you’re getting out of how many litres you’re putting in at the pump? Thanks

For a Yaris or an Estima?

If you mean the Mk4 hybrid, I tend to average mid-70s indicated/high-60's calculated. If I'm being extra sensible/boring or if there's a run of particularly good weather I can get it into the low-80's indicated/high-70's calculated. I find the indicated is roughly 5-10% optimistic on what I get from tank-to-tank calculations.

I don't run the tank to empty and usually fill up around a quarter tank left, but that usually gets me 380-450miles depending on how I'm driving, but this is a terrible way to gauge it as 'a quarter tank' has quite a big margin for error, due to the car having a digital fuel gauge using 8 blocks, instead of a more fine-grained analogue one.

It's quite a shocking car to refuel as you can do 400 miles and go to refuel and only get in 26-28 litres!!!

Sorry, I meant the Yaris. 
I’m thinking of getting one to replace my Honda diesel, and I can get over 70 mpg in that. 700 plus miles on between 42-44 litres in the summer. Winter is somewhat less but still a genuine 62-65mpg.

If you can get 400 miles on 27 litres that’s high 60s which is pretty comparable! Most of my driving is steady state A roads/motorways, so I’m wondering if the weight of the batteries would result in a lower real world figure than that, as I’ve heard the Yaris seems to excel in city driving

Two and a half months since new and 3001 miles covered. That includes week(s) holidays in Lincolnshire and Shropshire. Saturdays and Sundays I take the son to his work which is 2 days and involves 92 miles each weekend. The rest is just general localised running. The car states I'm getting 85mpg or so. Fuelling it top to top works out at 77.2mpg.

More than happy with that, and happy that I'm helping the Planet!

I got 450 miles on 28.2 litres. Mostly city driving.

One downside with the car is they seem to have put the fuel tank from a SmartCar in it, so it'll never do diesel mileages in one go - I think I got 7-800 miles out of my old Mk1 D4D once, but can't get close to that in the Mk4 - but you won't care because you'll have done 400-ish miles on less than 30L of fuel  

The first time I refuelled it I thought the pump was broken or something as it wouldn't take more than 26L! When I realized it was actually full I had a stupid grin on my face for the rest of the journey  

 

The Mk3 Yaris hybrid excelled at city driving, but the Mk4 excels at *all* driving - One time, I'd just fuelled up and went on a 120mile trip to the NEC via Milton Keynes to pick up friends. The car started off at 50mpg indicated when I got onto the motorway and even with 4 adults in the car and me burning up the M1 at 70mph it just kept going *up*!!

I think it was at 71mpg indicated by the time I got into the NEC carpark!!  We were pretty sure it was lying out of its teeth at that point, but the calculated tank a week or so later still gave me something like 65-67mpg IIRC!

The biggest improvement in the Mk4 is they stuck a reduction gear into the drivetrain - Almost all the hybrids that came before it (apart from the Corolla and Mk4 Prius I think) couldn't do more than 30-40mph without the engine cutting in; The Mk4 can go well over 70mph without needing the engine to spin (albeit you won't hold that for very long unless you're descending or have a disaster-level tail-wind!   The MG2 motor on its own only really has enough power and torque to hold maybe 56-58mph on a flat), so it's incredibly good at finding wasted energy and stuffing it into the Battery and then using it.

It's a good car to go to from a diesel - I went from my Mk1 D4D to a Mk2 VVTi because of KHAAAAAAN! and his stupid ULEZ, and it was *painful* going from a torquey diesel to a high-revving but gutless petrol.

The Mk4 hybrid does a good impression of diesel torque which makes it *much* nicer to drive than any petrol engine (And even kinda sounds like one because of the 3 cylinder engine  ), so it's a good alternative for diesel refugees!

Thanks for all detailed responses, just the sort of info I’m looking for 🙂

That’s a genuine 72.5mpg 👍

Toyota hybrids batteries and the whole cars in general aren’t heavier than any other cars in class. They have been designed very well and the batteries are small and light weight. 👍

I'm guessing the Yaris is a good portion more efficient than the X?

I've rocked up 850 miles on mine in a week, mostly motorway driving which it isn't overly efficient at and I'm averaging 58.5mpg, That's mostly cruising at 72mph. The X is definitely a lot more efficient at lower speeds and more varied driving that isn't motorway cruising.

For example: A 50 minute drive from Whitby to Scarborough along the cost road (A171?) covered 21.7 miles with the Hybrid on 55% of the time. Netting 67MPG. But a 1 hour trip between Leeds and Scarborough of mostly Dual Carriageway and National Speed limit of 65 miles netted 55.7MPG with the hybrid kicking in 23% of the time.

And according to the hybrid coaching I have a score of '84' which is pretty good?

What's bugging me though is my old Diesel claimed it got 55MPG and tank would do 550 miles and cost £80-100 to fill up. If I'm doing an average of 58MPG and a tank can do 400 miles, but only costs £40 to fill up. Something isn't mathing there. Lol.

[Cyker]

I would imagine at lower speeds they're quite similar, but the YariX has a significantly larger frontal area and higher ride height compared to the Yaris, and I can see that introducing a lot more drag/air resistance compared to the normal one at higher speeds.

I also forgot to mention I'm cheating slightly as I retrofitted 15" rims onto mine, which are narrower and have less rotational inertia and probably give a slight advantage in lower drag at higher speeds.

Well according to those figure your old diesel was probably doing 44-45mpg at best, whereas your Yaris is doing mid 60s.

Reducing your motorway speed by even 5mph would see your mpg rise no doubt, but it all depends on how comfortable or not you are doing that…

That’s not cheating, that’s being smart. Audi used to spec the original base spec A3 with 15” forged alloys that weighed about 5.5kg per rim. They’ve become a bit of a collectors item amongst A2 owners seeking the smallest lightest wheels possible…

I have a MY21 YX.  My dealer is trying to sell me a MY23.  He says the engine is version 4.5 cf mine at 4.0 whatever that means.  It has a new ECU.

It should have a 15% better fuel consumption. 

Really?

 

[TonyHSD]

Any car will be less efficient at higher speeds. 
Motorway runs at 60mph or below increase the efficiency by much because of the aerodynamics. I am a regular motorway driver and my typical cruising speeds varies around 60-65 mph and fuel consumption it’s very good, currently at 60mpg and this from an old Auris hybrid. 
Toyota hybrids together with all electric cars rely on the free rolling and inertia to achieve great efficiency and higher speeds , uphills climbs, extra load, fast acceleration, winter or all season tyres, low pressure in tyres, wet ground surfaces, heavy winds, cold temperatures all these affects them more than any other type of cars.
The best scenario for your hybrid and to see sky high mpg is during summer driving at night through town or county lanes at speeds up to 40mph , then the car will be like full electric, and engine will come to life only from time to time to recharge the Battery. Smooth, quiet and efficient drive.

I concur.   I set my motorway cruise control to 62-63 which is slightly  above the maximum speed of trucks.  On a free running highway trucks should no catch me up.

Where a truck is doing less than 60, particularly on a gradient, I am happy to wait until we reach a down slope. 

The only problem I have is with a following truck doing marginally more than the truck in front.  They see my spacing from the truck ahead as an invitation to overtake me, then I have no option but to pass that truck ahead.
