Consumption versus speed on motorway

[joga8]

Hello,

I am convinced that the phev is a good deal for short distances but I am quite afraid of high consumption for long journey on a motorway (500 to 1000 km) .
Could you give me an estimate of consumption on different average speed :
80 km/h
100 km/h
120 km/h
140 km/h
Thanks for yours answers because I have not found these information on the net.

For about $50 you can get a fairly decent HUD. These units are plugged into the OBD2 port and numbers displayed on the windscreen. Just plug in before turning your PHEV ON.

Most of these units will give instant L/100km. You will be able to get real numbers for the various speeds that relate to your own driving style.

Wind resistance is the primary load the PHEV will see on a flat motorway, and the wind resistance loading increases with a cubic relation to the speed.

Can you provide brand names for the HUD you mentioned.

 

[joga8]

Thanks for your answer but i have not bought yet a phev.
I would like to have a feed-back from phev owners.

 

[gwatpe]

My Phev give around 7 L/100km average on petrol alone.

The PHEV has no useful real time display of L/100km, and as such it will require a dedicated PHEV owner to provide data in a format that you are asking. The round dial provided is very agricultural and not really useful for what you are asking.

PS Ozukus, check on fleaBay. there are hundreds. look for the biggest digits and not too much info.

A real-time consumption would be usefull but I don't need precise figures.

I just want to get some estimate for different speed to compare with my actual car (Renault Scenic 7 seats with an average of 5,8l/100 km and app. 5 l/100 at 120 km/h and 7 l/100 at 140 km) - my style of driving is rather quite

I have read phev tests that are quite frightening with consumption of 12,3 l/100 km at 130 km/h
(french article http://automobile.challenges.fr/essais/20140226.LQA5846/mitsubishi-outlander-phev-le-bilan-consommation-a-la-loupe.html)

Thanks for your feedback

I have no difficulty getting 6.5 l/100 km out of it on a flat battery cruising at 100 kph. I can believe that it will drop off as you get up to 130 kph, but it seems unlikely that it will get as bad as 12 l/100 km.

it is a large, heavy car and not something to treat like a sports car.

At about 110km/h you should expect about 7l/100k.
Kind regards,

Thanks for your interesting feed-back.
To summarize the figures :
100 km/h : 6,5 l/100km
110 km/h : 7 l/100km
Any feed-back on higher speed 130/140 km/h (usefull on motorways in France or Germany) ?

I think that the 12,3 l/100 km at 130 km/h were certainly obtained with a style of driving not really peacefull
That's why I would like the feed back of real PHEV owners

Rule of thumb seems to be, fill up before you think you need to. Small fuel tank is designed for minimal high speed long drives. Redeeming feature seems to be a very conservative empty indicating fuel gauge.

Hello to all,

I bought an Oultander PHEV and have 4500 kms on it. I have one number which is 460 kms on a full tank at a steady 130 km/hrs French autoroute (15 kms were at 90 kms, 15 at 110).

Quite simple - with a full battery and a full tank I did 460 kms and had to stop to refuel as I had the low fuel warning. I filled 40 liters which means I used 40 liters to do 460 -50 of which electric which equals 410 thus 10.1 lts/100kms. When I fill I do so to the brim so that the quantity used between to full tanks is reliable.

Mitsubishi has agreed to check my car to determine whether there might be a problem which would explain such high fuel consumption.

On the electric part I have been keeping close tabs as to when the engine kicks in. With a full battery I get between 35 and 50 kms. Driving at 110 km/hr gets me 35-40, driving at 50 to 60 km/hr gets me 40 to 50. There are variations though which I cannot seem to correlate to anything. I am waiting for winter to arrive to determine just how important temperature is.

Otherwise I just love this car - it is a real pleasure to drive - I previously had a Diesel Outlander. The silence of the electric engine, even when the gasoline engine runs, is very enjoyable.

Thanks for all your answers

To summarize the figures :
100 km/h : 6,5 l/100km
110 km/h : 7 l/100km
130 km/h : 10,1 l/100km

Just one additional piece of news concerning fuel consumption. Latest figure at 130 km/hr is 9.6 l/100km

My Mitsubishi dealer PHEV technician told me that beyond 120 km/hr the car runs in pure thermal mode - there is no thermal/electric optimization. So, to get the benefits of PHEV one has to set the max speed just under 120 km/hr - fuel consumption would then decrease dramatically, from 9.6 l/100km to somewhere around 7.5 L/100km, but that is still far from the 5.8 L/100km.

To get 5.8 L/100km one would probably have to run at around 50 km/hr, so to get the 824 km range advertised by Mitsubishi, one would have to drive approximately a total of 16 hrs. So, range is good for local city trips but not for long distance driving.

In France, our high speed highways limit is 130 km/hr. At 130 I get 45/9.6*100 = 470 kms. If I run at 120 I get 45/7.5*100 = 600 kms. The extra 130 range at 120 km/hr enables me to refuel at every other stop after 2+ hrs driving each leg. At 120 km/hr I save money and optimize my stops. At 130 km/hr the 420 range (470 - 50 for safety) I stop one first time at 2+ hrs of driving and then need to stop after a little less then 1 hr of driving which is too soon.

With my old Outlander Diesel I would get 8.5 l/100kms at 130 km/hrs. My range was 600 kms before the fuel warning would turn on. It was perfect. I'd stop every 2+ hrs and refuel at every other stop. But I don't regret the PHEV purchqse since i estimate that I'll do a total of 120000 kms 2/3 of which will be in the 90 km/hr range with 50% pure electric. My total cost would then be :
40000 pure electric = 4800 KW-hr at 0.07€/KW = 420 €
40000 at 6 l/100km = 2400 lts fuel
40000 at 7.5 l/100km = 3000 lts fuel
Total cost = 420 + 5400*1.4 = 7980€
With the diesel version cost would be 800*8 + 400*8.5 at 1.34 €/l = 9800€

But the car did cost me an extra 7000€ pver the equivalent diesel version so I really am not saving any money, on the contrary. Conclusion, I paid more to have a new toy and what a joy to drive. Higher resale value, lower maintenance costs might be offsetting factors.

That's for my 2 cents.

In the UK the goverment gives you £5000 or about Euro 6000 to help buy the Hybrid car so the price of the Hybrid ends up being the same as the diesel.

I'm getting about 4.7l/100km without any great difficulty with mixed mode driving including plenty of motorway at around 100kph.

 

[greendwarf]

To go off-topic are there any public recharging facilities in France, especially on the Autoroutes? if so, how do you access them and what is the cost?
