Mazda 6 fuel economy, new model

jigsaw 2014

Evening all, bought a Mazda 6 last year , the new model and on a 132 plate..cost me a small fortune but I justified it with the fact I would keep it 10 years and recope the price in the savings on fuel and motor tax (Previous car was petrol 03 mazda 6 much loved and great car).
The Mazda spec states it does 67.4 miles combined, yet I am getting only 45.4 miles to the gallon, re onboard computer.....this is a huge differance.I have done 5000 miles so the engime is bedded in..any one else having this problem and not happy???????
As for the dealer no joy...

Thanks

You'll never get the optimistic official figures, I'd imagine your driving isn't ideal 55mph in a straight line sort of stuff?

Bpmull

Every car manufacture over states the mpg by 10-20 mpg not just Mazda. You need to work out the mpg manually too not just of the trip and the trip may be giving journey mpg rather than thank and do you reset it regularly. 45mpg isn't too bad for the car how you would possibly think it would do 67 its a big car, in short there's nothing wrong with it.

colm_mcm

I wouldn't be happy with 45 if its open road driving, the new 6 is supposed to be light and that new engine is supposed to be the next big thing.
If it was urban stop-start driving I'd be ok with it.

What is the engine power of your Mazda 6?

5k is nothing on a diesel, it will improve as the miles go up.

Yes I have done it per trip and worked it out and still 45 miles, it isa big 2.2 engine but I am annoyed that they sold me a dud,,, I had expected to get mid 50s given a 20%reduction on there figures..but the reaity is its 35% down on there figures and I have to say because all car makers do it does not make it right.thanks

If my car underperformed on its mpg atm by 20mpg i would be getting -2mpg

Still wouldn't care

Those new 6's look nice though they have stepped into honda accord territory

A lot of cars have been doing 40 odd mpg for a very long time now!
Its hardly progress eh?? It is a big car though so yeah its ok. But not newsworthy.

When you put it like that and consider your doing long trips then mid 50s would be reasonable to expect. I assume you've checked all the stupid thing like tyre pressure and all that. Although realistically that's not going to effect it hugely.

It's better than the old model.

Mpg plummets this time of the year with all the power sucking toys on. It will take a bit longer than 5k miles to break it in properly.

When did you get it? A lot of shorter trips in between the longer ones? It could be a dpf regeneration going on when it gets a long run.

When Mazda launched the new model it promoted heavily the fact it returned 67 mpg and still does..

Wow! Thats some claim. Well, i recently went down the country on a night out. Wasn't concerned about mpg since i was going to blow a few euro on coke and hookers. (AH joke)
I did motorway limits across the country and got 62mpg for the trip.
If a mazda6 can even get into the 60's after normal driving then i'm ace ventura!

Grow up what when its 100k miles its just starting to break in? 5k its all done.

Most of those figures for mpg are for flat road at 90kph and even then youd be lucky

Bit harsh.

The last Mazda diesel I had got noticeably better after about 30k km. Current car has about 21k km on it and the figures are improving all along. 5k miles/8k km is a tight new engine, it's an extremely valid point that diesels tend to improve with mileage.

Wouldn't be any harm trying 5th instead of 6th in some instances.
My old jag was more efficient at 100kmph in 4th than 5th
Your trip computer should give a momentary fuel consumption reading.

I'm guessing your short journies are the cause though.

Dont believe it. More likely your just more and more used to the engine.

The break in period if 90% done by 600 miles. By 2k miles its as much done as it doesnt matter.

The days where cars need a proper break in period is gone. Materials have improved and tolerances are so much better.

colm_mcm

I wouldn't agree fully with that corkgsxr we used to get brand new cars as company cars in the garage I was in, and yes, there was an improvement in mpg after the first few tanks, but the ex hire ones we'd get back in the autumn would Definately have more power and were better on diesel.

Just like Toyota claim they are the best built cars in the world, VW claim they are the most reliable. We know both are not true.

Like any product being marketed they tell you what you want to believe. You will never get the claimed figure just like broadband speeds.

I wouldn't worry about the mpg. You've paid an awful lot for it and will be paying a lot of depreciation year on year for some years. Enjoy it for what it is a brand new motor. An extra say 500 pa isn't going to effect the figures substantially.

So you paid over 30k for a big car with proper 2.2 engine to drive most o 6 gear and not over 100kph? You really believed in 67mpg? 67 mpg equals to 3.5 l/100km - even motorbikes burn more!

Just enjoy it!!! Use those torque and enjoy having nice car!

these journeys are probably the cause of the low overall MPG, I would guess that the car is probably doing MPG in the 10s or 20s for these short trips. Most cars need 5-10 minutes of driving to get up to normal operating temperatures and thus normal consumption

Agree...

First of all, trading in a perfectly working Mazda (but worth very little on the open market) with a new one means there would be no savings to gain for good few years, even if the new car runs on water.

Someone I knew spent 20k stg on a Mazda 6 back in 2004. It was a nice car but I would no more have given 20k stg for it then or for the latest successor. New cars are great if you want them but economy isn't one of the reasons you would purchase one.

Mazda are very reliable cars only problem is they depreciate faster than other cars The old diesels were a disaster whatever about the newer models.

That is what makes them economical overall, especially when you get a good second hand example.

You are never ever going to see a diesel engine perform to it's best when your main driving is an 11 mile work commute and 4 mile commutes with the kids.

Diesels take a while to warm up and only show their real efficiency on decent trips. There's absolutely nothing wrong with your car, mid 40s isn't bad for that kind of driving. Unlikely any other car of similar size would better it.

How long have you got the car to have only 5k up on it?
Unfortunately it seems your just not going the mileage to get the maximum efficiency from a diesel, so all you can do is enjoy what is a very nice car and forget about it.

No need to be too easy on it either. Engines like a good drive every so often, especially ones that do low mileage and have DPFs.

Being blunt but what the hell did you buy a diesel for when your doing nothing but short journeys? A petrol engined car would yield similar results, would have cost less and not be prone to the usual problems associated with all modern diesels doing short journeys.

I do bigger mileage than you to and from work each day and have school runs and youth clubs, etc etc runs to do but I wouldn't even consider a diesel due to them being short journeys. I'm getting 35mpg from my AWD legacy on short journeys and 42 on long journeys and have even managed 47 on a very long 400 mile return journey.

My brother has an 11 Civic 1.8 saloon. He gets constant 45mpg on his 7 mile to/from work commute and well into the 50's on a long run. He rarely uses 6th gear to/from work as it's less economical. It's a steady cruising gear for motorways only.

I think you bought the wrong car for your needs.

BMJD

I asked a Mazda dealer about a petrol in the new 6 and he told me they would only get them in on special order

colm_mcm

Were they cheaper than the diesel?

knipex

I have a 100 km round trip each day to work with all but 4 km each way on Motorway.. yet I consider myself borderline diesel justification (I have a diesel).

The car doesn't really warm up until I have 10 miles done and you can see the instantaneous fuel consumption drop during that period.

you need to be doing 35 to 40K km a year to really justify diesel with the higher service costs (and tyre wear) especially those larger engine high torque cars..

The Irish motor industry (particularly saled men) and the greens convinced the Irish public that Diesel was the way to go. Unfortunately the Irish motoring public (in the main) don't know what a Dual mass flywheel or Diesel particulate filter are. Don't understand the servicing needs or impact of shot trips on these engines. plus they don't realise the driving characteristics of a diesel is hugely different to a petrol..

We are starting to see the backlash from this and it will only get worse as more and more owners are hit with high bills and zero savings..

Diesel cars work best on motorways with cruise control where you will see good fuel economy or in an application where you need the torque.

If you don't do 35 to 400 km a year minimum don't buy diesel...

Now I am really depressed, as I really never thought about depreciation...

Jigsaw, if you're going by the trip Com, you're almost certainly not getting 45. I'd say you're really getting around 42 or 43.

Is your driving mixed? If so, its not too bad to be honest for a 2.2 petrol.

Anytime I see Manufacturers claims I subtract 20% from them as they're a scam. Though to be fair to you, that would still only bring you down to 52 or so, so you're a good bit under that. Honestly though, a large petrol car ain't going to return much more than what you're getting. Higher than that and you've gotta be looking at diesel I reckon.

I appreciate all that, however when you mentioned the maths, I did a quick comparison for the next 3-year of ownership between your old and the new car and my maths come into quite different totals. I have made some assumptions, like your approximate mileage and that the old car would need an extra €500 each year spent on repairs to keep it going.

16k km per annum New Mazda Old Mazda

Motor Tax 390 636
Insurance 700 500
Fuel 1481.76 1945.6
NCT 0 55
Service, tyres, etc. 400 350
Annual repairs required 500
Annual depreciation 6000 250

Total cos per annum 8581.76 3600.6
Cost of 3 years ownership €25,745.28 €10,801.80

The new car is going to cost you more than twice to run.

Yes the figures are a hard hit, but if u omit depreciation it is a lot better, and being honest I wanted to once in my life buy a NEW car, one of those bucket list things..And having saved for the day I would drive a car off the forecourt as a first owner , depreciation didnt come into it..now all I really want to know is this the mpg other mazda 6 owners are getting..thanks to all for your replies it has been an education..
