Nissan Primera 2.0 Petrol - never did more than 24mpg no matter how carefully you drove it. It didn't have any performance either, but it was the family car for 10 years, covering 160K miles before I traded it in.
I struggle to get a 2.0MX-5 above 30mpg on the daily commute
Nissan primera.... We had a 2.0 sve. What a turd of a car... Thirsty and unreliable. It was only three years old with 28000 on the clock but ranks as my worst car everI struggle to get a 2.0MX-5 above 30mpg on the daily commute

Aygo at motorway speed or above are shocking.
Yeah, Aygo is a great example of buying the right car for the job.
On holiday in Mallorca our hire car returned 58mpg over the two weeks.
I got home and decided to buy one as a run around, bought a new Aygo Black hung over, however, the reality was back home they are not set up for anything other than city driving.
Sit at 40mph and it will do 65mpg, 50mpg sees that drop to 40mpg, get up to 75mph and it is struggling to get much above 30mpg.
I disagree. We've got a Peugeot 107 (owned since 2009) and it will (or would) do a true 68mpg at a steady 60mph. (Worked out manually on a full tank)Yeah, Aygo is a great example of buying the right car for the job.

I used to drive a 1.8L Mercedes C180, on the motorway it'd return over 40mpg which was perfectly reasonable, but around town it tumbled to 24-26mpg, which I thought was a surprising difference in figures.
I presume this is the same engine we have in our GLA180 although I think its a 1.6L? Either way the GLA gets around 29mpg and is just awful at economy driving. Our 1.8L TT that we swapped it for used to do easy mid to late 30’s and my 2.0 Mazda 3 is currently on 50.4mpg so the Merc engine is surprisingly thirstyLHB said:

Wifes 2019 100ps fiesta 25mpg pretty sure the st with double the power would better that.
My remapped (165bhp) 1.0 ST Line does 31mpg, the STs I’ve seen are getting about 35-40

Mk5 golf gti dsg = 25mpg
2005 polo 1.4 auto = not a lot more....
Lol crazy. 2005 polo 1.4 auto = not a lot more....
My S205 C63 4TT v8 hasn’t yet had a tank as low as that in over 5k miles. It’s best 30mpg it’s worst just under 26mpg.
That’s with more than 2x the power and more weight
The cylinder deactivation so it runs effectively a 4pot 2ltr T and it’s glide mode in the auto box really do make a difference. So does the map setting Comfort sport sport+ And the exhaust open or not open I think oddly it’s marginally worse if open - not measured a tank on that as I love the noise too much to do it for an entire tank

Jaguar S-Type diesel, no matter how you drove it or where it was it never did more than 32mpg with a low of 19mpg on my congested commute. £105 to fill it up and it never did more than 400 miles from the tank.
If someone comes up and says my one must've been broken you're probably right, along with all the other stuff thatthey all do that was also broken, what a dogs
t car.
No, mine was a dogsIf someone comes up and says my one must've been broken you're probably right, along with all the other stuff that
t car. t car too and averaged 29mpg. Would have been far cheaper to run the 4.2 V8 given all the engine related woes.My NA MX5 was very poor for a light car with a modest engine. The ECU was a primitive 8 bit job in most of them that went open loop over 3000RPM (IIRC, might have been 3500RPM) and the short gearing meant that on the motorway you were always running open loop. One of the later special editions had a 16bit ECU, but as others report that the NB was also poor I don't think that helped.
FWIW my 2019 ND MX5 is incredibly efficient.

18.4 mpg on way back from Austria last week in RRS P400E. Definitely miles greener than a diesel doing 30 mpg 
Average at the moment is 26 since I got it over 23,000 miles
Has the charge cable ever left the boot?Average at the moment is 26 since I got it over 23,000 miles
Yes I know bought the wrong car but the BIK makes it work. What I have been most disappointed with is that it seems to really struggle when you add a full boot and 3 people. Which all my Dads Range Rovers never did. They always had this sort air of unstoppable ability to carry stuff and people in comfort at speed. Seemed to shrug everything off effortlessly whilst getting 25 mpg no matter what.
My A35, which I didn’t expect to be great on mpg is worse than expected. I have seen as low as 11mpg on on 3 mile round tip to the local shops, granted that’s from cold but in comfort mode. Normal around town driving is upper teens when warmed up. Overall about 28mpg largely made better by 300 miles a week at 50/60mph on the m3. Without that I expect it would be sub 20mph which I didn’t expect.

My old mk2 focus ST. 220bhp, 5 pot. If I drove it like I stole it, it did 19mpg. If I drove it like a granny it did 21mpg! 
I had a fuel card and between tyres and petrol I think I bankrupt the company.
A mate had an RX-8 (under car allowance scheme rather than company car) and a fuel cardI had a fuel card and between tyres and petrol I think I bankrupt the company.
He was told change the car or pay for the fuel yourself
