Real mpg’s
 

Who's going to force them?

At the moment they seem to be able to remove stuff, tape up all seams etc to get better figures.

Manufactures quoted mpg should be classified as false advertising as it's clearly complete tosh. Not heard this becoming law though.

They need to hammer the hybrids on this; Loads of people moan about the real world Mitsubushi's Outlander PHEV. The use of this tech massively skews MPG figures which only represent a 30minute commute.

Fact of the matter though is you can apply a lot of common sense here: If you have a car that is shaped like a brick and is tall (SUV, 4x4 etc), that weighs over 1500+kg and has huge wheels, it will need a increased amount of horsepower for it to maintain a set velocity. It will also require more torque to accelerate.

Fact of the matter is regardless of the powertrains, modern cars are far bigger, taller and drag along a extremely heavy chassis with a drivetrain that has a fair amount of complexity and parasitic losses (i.e using a alternator to generate power to drive a electric motor is less efficient than using a belt to directly drive it - if a solenoid/clutch system was used to engage/disengage or vary loading- cooling fans, power steering, water pumps etc. would be better driven via belt...we've gone backwards in a big way here). The end result is a modern engine no matter how efficient needs to produce more motive energy to accelerate and maintain a set velocity.

Ah but it makes you FEEL better that you BELIEVE youre saving the planet

Yes, I almost enjoy paying green taxes....

Oh yes hybrids need to have emissions tests. They are currently exempt from emission testing :cuckoo:

It quite easy to gauge mpg of ICE engines, just look at the worse number they quote, which is usually city driving. That is the mpg you will get.

Hybrids are just silly with their quotes. my XC90 hybrid does about 38-40mpg on a long journey. It does >100mpg when your journey is less than 25 miles. Fortunately for me that is about the maximum I have to do, so use all electric for all but a small portion of the journey.

Hybrids should have emissions test like any other ice vehicle.

Even if you're doing 100mph for that 25 miles ?!

Eh!? The most I can do on the journey is 60mph down a dual carriageway, average speed for whole journey is less than 30mph

What's so wrong with lab results?
Using the exact same criteria to test all cars will give you a comparison figure.
Real world results can vary enormously due to numerous variables.

Because people are easily mislead. My friend got a mini because she thought it did 75mpg. She is disappointied that it only does 55mpg. I told her to check the city mpg and that is likely be about the same number

What did she think it ran on ...

Sunshine maybe ?

Just got duped by the max figure and salesman. Salesmen are lying barstewards and not to be trusted. Do your own research beforehand

Agree with Andy.
If you are going to quote, at least tell the truth.
What's the point of a fake figure?

Are they not just repeating what the manufacturer states ?


you need to apply an element of common sense here imo

There's nothing wrong with quoting laboratory figures, as long as you make it explicitly clear that that's what you're quoting and that real world results may vary.

At the end of the day their are so many variables that can effect fuel consumption that these figures really are only vague indications at best.

I ignore all figures apart from EPA. When I go into a dealership and they start waffling NEDC, I stop them and say what is the EPA number, if they can't quote it then I just say thank you and leave. I did the same with the Nissan Leaf, I only confirmed my order once I had the EPA for range.

I use https://www.honestjohn.co.uk/realmpg/ as a guide to what cars get.

My wife's 5008 has over it's life achieved 47.4mpg. Official figures are 53.3 Honest John owners average 48.2

Definitely worth checking what other owners get rather believing what manufacturers say.

The pistonheads real world MPG wiki is quite good to. That and (assuming they've reviewed the car you're after) the autocar magazine reviews, they do quite a sensible real world MPG test which is a reasonable indication.

My boss has once of these, on a full charge it manages 25 miles, then tugs along at 30mpg!! :wonder:. Road tax exempt and very friendly on the BIK tax :cuckoo:

I specifically pointed that one out as I steered a friend away from having one because it is attcrocious for high-mile drivers: He does over 50,000 miles a year, so the Mitsi PHEV would have been terrible for this kind of use.

Of course, unless you live/commute in and out of London's congestion charge zones on a daily basis where it is exempt (once you pay the £10 'admin' fee to register it). :rolleyes:

He didn't, so ended up with a Skoda Superb TDi (2017 model, so post Nox scandle )...He's chuffed to bits with it.

50k miles a year. Bloody hell, he must near enough live in the fecking car

About 200miles a day...It does smell a bit inside! :o

I've solved my MPG issue by buying a Discovery .. now I just simple don't ..

30 mpg on a run

9 -19 round town

3.0 H6

Never ever believed sales figures on mileage,

Or any other sales crap for that matter

I bought the car, i live with the MPG

Scared the **** out of me when i drove it back, the way it could make the

needle drop on the gauge :eek:

I was convinced it was going to clear a tank in 100 miles

Now i know i can get 300 miles on a tank its not too bad

you can moan about fuel consumption all day , but its all dependant on your right foo
 

Ran out of fuel yesterday close to Aachen tipped in 5 liter then filled up 57 liter on Aral 102 at Eschweiler and drove home just past Frankfurt. Distance travelled 263km that's 164miles, but had to coast into my driveway on fumes only.

164mile /13,2 gallons = 12,4 mpg but having fun for 1 hour 28 mins.

Equally the drive from Farnborough to Aachen at Constant 120 kmh was 348 miles even if I calculate a full tank is 26.4 Mpg
But was actually only 3/4 full when I left so more probably like 35 mpg

So if you want to drive fast its going to cost 3 times as much,
accept it as being a Scooby owner you must.

By the way
Yellow light gave just 12 miles at a constant 120kmh in Belguim.

Same here....I consider people who moan about MPG and high road tax on a performance/big engined car imbeciles.

How many threads did we have on Scoobynet moaning about low 20s MPG on Turbo'd Imprezas? :facepalm: Admittedly it is quite poo when I swapped mine for a Monaro VXR, which was better on fuel despite being bigger/heavier/more powerful etc. :lol1:

The VW R32 buyers were just as bad, in fact I point the figure at consumer pandering to the main reasoning for it being replaced with 'yet another 2.0 4cylinder' :sleep:

When we needed good MPG and lowish tax we bought a diesel...admittedly, it's 2000kg with two turbos and 290Bhp/440lbft. But it happily potters around averaging 40mpg on most runs.

astra sri sports tourer 17 plate
16v 1.6 turbo petrol 212bhp in sports mode 290 miles devon countrysidedriving managed to average 51.3 mpg with average speed of 41.2mph
now slow down around town in traffic etc average speed of 24.7 only managed 46.3 mpg over roughly the same amount of miles :thumb:
