Rejecting Car Based on Misleading MPG

[anonymous-user]

So it's the car's fault that you can't drive?

This:





is a very expensive violin.

If i bought that violin, would you say it was the violins fault that i can't immediately (within 2 days) play Beethoven's Violin Sonata No. 9 ???

[djdest]

OP, have you looked on sites such as Fuelly to see what mpg other owners are getting in real world driving?

The 3008 is your average-sized SUV. Combine that with a wheezy engine of only 1600cc and it's not surprising the economy is poor, small ish engine shifting a heavy great crossover. I've never understood why people expect small ish engines in big ish cars to manage incredible MPG figures, especially the claimed combined figure which is well known to be pretty unattainable in real life. I have no idea what the claimed figures of my cars are but I know what I actually achieve with them.

The biggest problem and why you will never achieve the quoted MPG with your car is that it is a SUV. The effect of stilting the car has killed aerodynamics. It probably has 2/3rds more frontal area than a supermini and 1/3/-1/2 as much than a normal hatch.

I run a rough worse case scenario in my head why buying cars:
Diesel - take 1/4 off quoted MPG figures
Petrol - take 1/3 off quoted MPG figures
Hybrid with motorway use - take 40-50% off quoted MPG
Hybrid town/local - take 1/3 off quoted MPG

I'm not sure why you believed the salesman or the brochure?

Because if you bought any other product you’d expect it to do what the manufacturer claims?

Is it not a government test rather than a manufacturer?

Exactly. Even the Gov admit they cannot replicate real life:

It's not testing a LED lightbulb that states it produces 250 lumens, it's to provide a baseline comparison with other models.

Ahahah this is possibly the most ridiculous question ive ever encountered and yes i ask some stupid questions myself but jesus christ.

[Trevor555]

The worst one I had was an Audi A1 Tdi which the brochure said 78mpg.

It did 45mpg around town, and the best I ever got on a long run was 58mpg.

Complained to Audi and they said "that's about right"

So it's not such a stupid question OP, we've been misled for years.

[Far Cough]

Help .... My car has run out of petrol. Can I reject it as nobody told me it would need to be re filled.

[threadlock]

To be fair to the OP, he's taking all this abuse very well. Respect.

Hi

I bought a 2017 Peugeot 5008 SUV GT Line 1.6 diesel on the 4th July. After two days of driving it, it has become very apparent that the purported 65.7 miles per gallon combined claim is never going to be attained. Real world is more like 44.5 MPG. I drive like a saint.

What are my rights in this regard? Can I hand the car back to the dealer for a full refund? Have already emailed the dealer to express my dismay about the very misleading economy figures.

I bought the car to replace my Land Rover Discovery 4 to save money on fuel. I’m in the UK by the way.

Thanks

Can you achieve near the extra-urban MPG (this is an easier one to get closer to in the real world as involves more steady driving) ?
Have you checked to make sure there is no underlying issue ?

Have you had any diagnostics done to ensure car is running correctly (injectors working correctly, egr not clogged etc)?
Has it been serviced recently?
Are your tyres inflated correctly (also it the tracking correct)?
Have you tried an Italian tune up and/or a good steady motorway run ?
Have you tried a good quality fuel such as V power?

[OldGermanHeaps]

It is across the board bullst though and it would be nice to see the purveyors suffer for it. If you went to the shop and bought a 12ft ladder and when you took it out the box and it was 8ft no one would question you. If you bought a tv that was advertised with 6 hdmi ports and it only had 4, no issue, full refund. Buy a 12" 3 speed dildo and its only 8" 2 speed no one would bat an eye about returning it, but broadband s or car salesmen can lie to your face and you are just expected to suck it up and say thank you.

This forum can be pretty abusive sometimes, or childish, however you want to put it.

But before you all tell me where to go I'll also say there's some great members with loads of knowledge, so I hang around.

You can't blame the OP for being peed off, not everyone is aware of the facts when it comes to missleading Mpg figures.

Oh ok. Well I guess I know the answer now. Thank you.

Sorry, I’ve been thinking about this some more. Yes, you fking should and no, I don’t actually think it’s a stupid question in hindsight.

They lie to us, albeit through a system of highly unrealistic tests skewed to make them look better than they are. Also the fuel economy you’re getting is significantly below advertised.

I’d speak to the manufacturer rather than the garage.

LOL - what mpg do you expect, 10000mpg? some people need a grip on reality, guess you dont want to buy a Hummer then any time soon...

But violin doesn’t claim to be able to do that, the car data does

The test is a government one hence the new test which is also been defined by governments it's also the reason the M3 is being killed off early as it won't meet the new test requirements.

No, he expected it to be somewhat close to what it was advertised to do, which is not unreasonable

[Dan W.]

Yes new tests should be more realistic figures wise, just means I have no bd new cars to see for a few months until they have been done

Who won't care and will bat it back to the garage.

At the time, the car was tested in the appropriate way, it isn't the manufacturers fault that it doesn't achieve the figures based on such flawed testing criteria.
