Who needs Hybrids when you've a Diesel A3?!

Logged this after a 37 Mile Journey from a cold start early on Saturday morning.

Since new in September the car has done 14,500 miles and averaged 51.6 true MPG. It seems to be getting better by the month as everything is loosening up. It shifts when it needs to as well! grin.gif

No wasted greenhouse gases in the production of banks of batteries, drive motors, etc either.

Our 1.9 Tdi 130bhp A4 used to pull that sort of MPG when you did 80mph all day long - they are superb!

Whereas this is the reading from a 3.2 after a similar distance;

Oh, and I zero'd the trip & mpg when I filled it this morning so the mpg & fuel used is for the 48 miles shown, engine was fully warmed at the start...... ECLIPSe.gif

DD, Does your Temperature reading always sit that low?

Stewart, how many miles did you actually get out of that tank? I find everytime that the miles remaining is always well over optimistic just after filling up, I guess it's cos it assumes those miles will be done in one run at current conditions and doesn't account for any cold starts.

No the car had been driven earlier in the day, I just started it to take a pic of the last recorded mpg to contrast what is possible with the diesel and what is 'possible' ROLLEY~14.GIF with the V6.

The temp normally runs about halfway on the guage and definitely wasn't low on a 15mpg run!, it does normally average around 23-24 though, according to the trip computer mpg no 2 - still it's only money..... 169144-ok.gif

Yes, mine is currently showing 240 remaining after 48 done on a full tank of Optimax, I mean how ridiculous is that? ROLLEY~14.GIF

I bet the 3.2 is much more fun than the high mpg diesel though! grin.gif........................bike.thumb.gif

From my receipts (it was a while ago) I ended up with 46.1mpg from that tank. My normal is around 35 - 38 but that's always short trips. The one I took the photo of was a round trip to Glasgow then down to Ayr then back to Glencoe, so it pulled the tankful up to a nice economic average 169144-ok.gif

And yes, it always over-estimates mine too. I always have it set at that setting though, the one that shows you 'actual real time usage' is up and down like a yoyo... and scarey! It's good fun trying to get it to go up on a longer than normal journey, and end up back at the house with more miles than you left with grin.gif (Much easier if you've had a speedy run before)

Well, Original poster here, I've still got the car and its coming up to start its tenth year with me, Approaching 140,000 miles, it's still got the original brake discs and pads with no sign of them looking like needing replacement. (car is garaged so I guess that helps)

 

I track my mileage and fuel usage using an app called 'fuel log'  ..here's the last few fillups...

I'm guessing it's ran-in now  ;)

Wow.  I'm guessing you drive quite carefully, then?  That probably helps with the mpg, and goes to prove that the cheapest way to improve fuel economy is to improve your driving...!

Probably almost +++

Yes, I work shifts so the 'out of hours' motoring means more time for anticipation and less need to be in a mad hurry!  +++

So that's how the manufacturers get the almost impossible fuel figures.  They outside of rush hour!

 

 

I know my mpg is great when crusing, but sit crawling in traffic and I can see the figure dropping.  It is disheartening - along with the waste of time.

140k on original discs and pads? Yeah, ok.

140,000 miles on the original brake pads?  :roflmao:

 

Please don't ever drive behind me.:roflmao:

 

I've done 18,500 miles on a single tank of fuel too.  It's about as likely.

They're in a heated test cell (so the warmup phase is much shorter) with no other traffic driving against a set accel/decel pattern that bear no relationship to how traffic behaves in the real world.

 

Manufacturers figures are comparative onl;y, they have no real meaning other than that - except if it's the figures for a hybrid when they have no meaning at all (if you don't believe me look at the CO2 and mpg figures for the Vauxhall Ampera and compare them to what a journalist got when using it for the daily commute - worse than his daily drive Golf Diesel!).

Yep, my mate at work bought a Pug 3007???  Hybrind thing for the high mpg, low CO2.  Funnily enough, the mpg has been awful, ie not quite half the claimed, and he is out of pocket for business mileage.

He took it to Pug and they did alsorts, to no avail just stating they were the 'official claimed' mpg figures.

 

He's gutted as it isn't even a good drive to make up for it.

IMHO the official mpg/CO2 figures for hybrids are so far away from what is achievable in the real world they're verging on fraudulent.

 

Plus another scam is the the cost per mile figure quoted - currently they're running adverts on Wave105 with Tiff Needell claiming you can get from London to Brighton for less than £1 (50 miles at 2p/mile). OK so what about the cost of the electricity the night before while it was plugged in? By ignoring that they are making a fraudulent claim again IMHO.

Yes, they are.  The figures are completely unrepresentative of what people actually achieve in practice.  But the manufacturers are not to blame; published mpg figures must be according to the EU-mandated test protocol.  To publish other figures is actually illegal.  So the EU actually forces manufacturers to publish fraudulent figures :unsure:

 

The theory is that it allows a valid comparison between cars - but while that works between two internal-combustion engined cars, it clearly fails as between an IC-engined car and a hybrid.

I'm not so sure.  I would imagine you might well be able to charge the battery for very little.

Check out the stories today about the introduction of charges and/or increased pricing for public charging points http://www.bbc.co.uk/news/technology-28054738

 

Even at home don't forget that charging a battery is at best 60% efficient and with electricity at around 15p per kWh the cost of charging at home isn't insignificant either.

 

Oh and don't get me started on the CO2 emissions from electricity generation in the UK (where most of our electricity comes from natural gas fuelled power stations... http://www.electricityinfo.org/co2emissions.php

It won't stop the progression to electric though.  15 years from now I think almost everyone will be driving one.

 

Perhaps I'm wrong on the cost, but it is still going to be a lot cheaper than petrol running (if everything else remained the same).
