I can't believe I saw this on my trip yesterday.

Round trip of 200 miles just to have a cuppa and a cheese roll with my brother, and to show off the car of course biggrin

About 40 miles of normal roads, the rest motorway with quite a few 50mph average stretches.

41mpg for the whole journey, in a sports car!

This is the same sipping of fuel that I'd get out of my Duster when doing this journey.

Except at 80mph the Dacia was being thrashed, has the aerodynamic profile of a brick, and although I loved it (Such a useful car) it always felt a bit nervous at motorway speeds whilst the Alpine was solid, and remained so at ***mph wink

Also it was comfortable, I'm now seeing this as a little GT car smile

I tend to average about 37mpg, but managed just over 46 on the 100 mile run to Dover last week. It was a small recompense for the 50mph stretches of the M25 and M20...

But remarkable in a fully laden car, two up, that can also do 0-60 in close to four and a half...

A bit of click bait there! I thought you had actually done it!. I did see 49.6 on a long run fesooned with 50 limit and was quite miffed that I hadn't quite made 50 - if you can't have fun in the car (rare) you might as well focus on something else.

Sorry for the clickbait laugh

Yes it was just twice on that trip that the average read over 50mpg, for a very brief time.

Just really surprised me, never saw anywhere near that in my Abarth.

I'm pretty good at being able to get high MPG out of cars when on long runs/motorway etc. For example, I managed to get 42mpg our of my Evora 400 between London and Wales.

My Alpine usually sits at an average of around 33mpg but I really struggle to get it over 40mpg on a run and that has surprised me, especially given where the average sits. I'm seeing very little difference between "enthusiastic" driving and cruising.

Even doing c500 miles to/from Liverpool plus 650 miles on the IOM recently it averaged 31.5 mpg and the 650 on the IOM were not driven slowly with the full extension of the right pedal generally in use when accelerating, we tend to stick to the derestricted roads where possible.

I did wonder whether the engine was still "tight", it's got 7K on it now. Was wondering if anyone has seen the mpg improve with miles driven?

39.74mpg average over near 12,000 miles since new. Lots of longer trips and mixed driving. No track.
Best individual tank I've had 43-44mpg. I am curious as to how people are getting high 40's, unless they are all the time in 50mph average speed camera zones!

I often see 47-48 mpg on the run to and from Donington (from Colchester area). I run the tyre pressures at 34 front and 35 rear (cold), and set the cruise control to 68mph.
I don’t see 47-48 mpg around Donington though..

I only see 40+ MPG after driving in 50mph zones. High 30s much more common, and is the average across 17k miles. 32psi all round.

Unfortunately didn't take a picture but managed to see 51.5mpg on a 150 mile trip to Spires Tuning from East Sussex. The result of the visit was a fun track day at Bedford which returned 16mpg!

I did 50 mpg imperial - over 399km
(displayed 5.6 l/100) and an average speed of 83kmh
was so surprised I took a photo of the dash

at an average of 110kmh (70mph) over several hours..

pe no gpf probably helps.

I once managed to do 5.2-5.3L/100km (roughly 53 mpg?) on the motorway stretch between Rotterdam and Antwerp, because I wanted to save 40 cents per litre on Belgian petrol... I had to switch off the air conditioner (which happened to be quite thirsty) and use cruise control.

The best I have done between two refills was 6.54L/100km (which equals 43 mpg), when I had to drive the autoroute from Valence to the Luxembourg border in one go because there was no petrol available in France due to strikes.

Stats over 35k from new (touring, d*cking about, no track):

Average: 35.7 mpg / 8.0l /100km
Std dev: 4.2 mpg / 1.0 l/100km
Max: 46.3 mpg / 6.1 l/100km (this was a constant 70mph back from Scotland)
Min: 26.0 mpg / 10.8 l/100km (this was d*cking about in Scotland)

Chapeau to those getting over 50mpg / under 6l/100!

51.8mpg on a motorway run of 1½ hours, mostly 50mph limits with some 70. Final mpg over the 3½ hour journey was 45 mpg. So 50mpg is achievable, it's just that achieving it isn't very exciting biglaugh

Sticking to 106km/h (66mph) on cruise control in a country famously as flat as a pancake, my bog standard PE returns a very repeatable 47mpg (6l/100km) on a run. Short of overinflating the tires, I don't think it could do better. All in all, I'm seeing 12l/100km on average (34mpg) which I'll happily take. My Elise with TB's won't beat that...

Let alone the Alpine's predecessor (350Z), which would do 34mpg on the same kind of run where the Alpine manages 47 - and on average, it did 22 where the Alpine does 34. Funny how fuel consumption is never a consideration for me to buy or reject a car but I still always obsessively keep records of it.

I'm currently on a trip, 2000 miles so far. Blasting across France then Spain at the legal limit and then some when the odd local came past at a rate.

Mountain roads in Tenerife using Sport Manual and some country roads as well as driving in the cities.

35mpg so far smile

My 911 does 32 mpg.

For a car that gets to 60 in 3.6 seconds I think it is amazing.

And it has not cost me a great deal to run either, servicing has been good value from the main dealer. £310 for an oil and filter change.

I did 450 miles in it yesterday, I love it.
70,000 miles on it now and it still feels like a new car. Not selling it
