Hello!

I know there are occasional discussions about "concerns" over long distance MPG of the Outlander when it is not possible to charge regularly, so I thought I would post about my experience of a return trip to France. I was pleasantly surprised!

Firstly, shout out to the fantastic PHEV Watchdog app and the recent update that allows 'Resume previous trip'. Would highly recommend to anyone vaguely interested in what their car is doing!!

Attached are the trips to / from France from the north east of England. Started near Darlington -> York -> Dover / Dunkirk -> Aubusson (Paris route). The outbound trip included a slight detour via Lincoln. In both cases, the car (a 2014 4HS) started with a full battery and included x1 rapid charge to 80% in York.

As can be seen from the image, on the outbound trip I averaged 41mpg over the 824 miles; and 47mpg for the 804 mile return (neither figure adjusted for the pre-charge on the battery).

On both trips, I set ACC to 62mph (on the dash) which is 60mph on road and let the car do its thing - not using charge / save at all. On the outbound (12th October), there was a strong head wind in the UK and heavy rain, which died down once in France.

I will be doing the same trip this weekend but going via the tunnel. As yet, I am undecided whether to go via Paris (which is motorway nearly all the way through France) or Rouen / Orleans, which includes a number of city and 50mph roads with roundabouts - there are also more hills on this route in northern France. It would be interesting to see if the averages are vastly different, though!

Oh, by the way, I have fitted Vredestrein Quatrac 5's all round which I am convinced has massively improved the MPG performance over the Toyos.

I know tootling along at 60mph isn't everyone's cup of tea, but it suits me fine and it helps me save a few quid on petrol too! Talking of which, can't help but be impressed that, on a trip of 2,600km, nearly 1,000km were on pure electric - nice.

Hmmm, by definition if you drive 2,600km without plugging in with a car that has an EV range of about 50km, then 2,550 of those km were driven on petrol - you just deferred 1,000 of those km for a while.

Surely yes and no! Yes, if you haven't charged the battery from the mains, all the energy used will be derived from petrol in the tank but no, because some of the time the car will be driven by energy stored in the battery on the move either from regen or surplus from the ICE not immediately used. This will be especially true when cruising at 60 mph rather than flat out at 80 mph down an autoroute.

If the OP is taking this from the %EV display it may be this is calculated by the car taking the above periods into account.

TANSTAAFL - as they say - it is certainly true that a hybrid had scope to run the petrol engine closer to its optimum efficiency, but in the absence of mains charging, every km travelled is derived from petrol burned - at least unless you are measuring over a one way journey that starts at a greater height above sea level than it ends. To say that 1000km out of 2600km travelled was done on pure electric is very misleading - those 1000km were achieved to a large extent by burning rather more petrol than was strictly necessary while travelling the other 1600km. That is not to say that the overall fuel economy was not better than it would have been in the same body shell with a simple petrol drive train, but it is no way near as good as the OP's post seemed to suggest.

What about the fuel consumption at 130km/h? Can anyone share some data about this?

Interesting and bloody amazing mpg, well done.

Good question re: 130km per hour (80mph), would be interesting to know but unfortunately we can't legally go that speed in the UK so can't help ;)

I barely managed 53kmg/33mpg/4.4l/100km at 110km (just under 70mph) but that was over a very short/specific motorway trip using just the Mitsubishi onboard estimate.

We did a 2100 mile holiday to France and got an average of 33.3mpg over the trip (brim to brim measurements). We were four-up with a very full boot and large roof box. And we took full advantage of the very good autoroutes so probably over half the mileage was at 130km/h. We were in mountain country for quite a bit of the trip, so it wasn't all easy cruising. Probably only about 200 of the miles were pure electric.

Of course it is a lot lower than our usual average but quite acceptable for a large car I feel. I do wish that the tank held a couple more gallons though!

Interesting comments! I actually drive this route fairly regularly and have done several trips over the summer - a couple of times with an 8m twin axle, 1250kg caravan (plus a decent load) and ran the entire journey on ICE (using the charge button). From memory, the battery rarely gained the entire journey, always showing near depleted.

The stats from Watchdog were as follows:

1234km travelled, 27km on electric.
14.6L/100km = 179.9L used. (19.34mpg)
76km/h average speed.
9% coasting / 17.9% regen.
Time taken: 16h 59m 57s

@Daff - I am with you, I wish the fuel tank was bigger - especially when towing a caravan and you are lucky if you get 160 miles from the tank, needing refill every 3 hours or so!


I also repeated the trip as mentioned in the original post, and here are the figures for those that are interested, comparing the two routes through France:

Southbound (via Rouens, Chartres and Orleans)
1380km travelled, 527km on electric
6.7L/100km = 92.9L used. (42.1mpg)
80.2km/h average speed.
8.2% coasting / 14,4% regen.
Time taken: 18h 14m

Northbound (via Paris)
1259km travelled, 435km on electric
7.2L/100km = 90.4L used. (39.2mpg)
83.3km/h average speed.
7% coasting / 10.2% regen.
Time taken: 15h 47m

Both trips started with 100% battery and included x2 rapid charges to 80%. The northbound trip included heavy snow / rain through France and strong winds which I think accounts for the worse figures.


With the 130km/h question - I will be heading south again toward the end of November and so will plan to do a 1 hour run at 130 km/h and see what figures I get. And, for the good of the community, I will also do a 1 hour, 110 km/h run to compare averages at 60 mph, 70 mph and 80 mph.

A while ago, I did a similar experiment in the UK on a 40 mile straight of the A1 in England running cruise control at 70 mph rather than my usual 60 mph. That was in a different car but what I found was the average speed for the trip being set at 70 mph was only 56 mph, whereas the 60 mph trip was 52 mph. I can't recall mpg but, it made me think that the constant re-accelerating and higher speeds would be using more fuel for little net gain.

Of course, that was UK roads with our typically heaving traffic and so will be interesting to do a comparison in France.

Thanks for the comments!

As I posted elsewhere in the summer - slamming down the autoroute to the Riviera @ 85 mph under cruise control in 24 hours (no recharge for car just me :lol: ) the car showed average EV and mpg of around 27.

NB. Just me in car but didn't take off the roof bars - so. if I had (and kept to speed limit or lower :o ) I might have got it up to low 30s. :idea:

Just thought I'd add my first experience of a longer trip with no charging being done.

Over this weekend did a trip from Peterborough to Bath, two adults on board with luggage - full tank of unleaded to begin with and a full charge;

Outbound journey A mixture of A roads, faster A roads (A34 - dual carriageway) and motorway (M4) as well as some local driving in town and around built up areas.
Car displayed 41.7 mpg, 43% electric driving.

Return journey Same but in reverse.
Uncanilly car displayed the same 41.7 mpg, but this time 42% electric driving.

Total distance approx 325 miles, arrived back with just less than a quarter of a tank of unleaded and zero charge.

Happy with the above!

So far, 1100 miles done, £84.33 of unleaded put in and £23.95 spent on electricty. Given that I still have probably 50 miles of unleaded left, total cost per mile of £0.094. This will obviously go down as I do more electric miles.
