MPG update

knightstyle

As we have now done over 1000 miles since buying our Toyota Auris I thought I would post the MPG. 47.8 mpg This is for an 07 1.4 diesel automatic, the best mpg we have ever had for an automatic apart from the Smart Fortwo which gave 50.3 mpg. Mixed driving, couple of long journeys and lots of short runs of under 4 miles.

To put that into perspective, I have a 2004 Mondeo TDCi 130 with 148k on the clock. If it got as low as 47.8MPG, I'd think it was broken. Small doesn't automatically mean more economical.

Is yours an auto?

We have the new 163ps with a powershift box and its averaging 31mpg (brim to brim).

Lets hope that it gets a bit looser with age!

To put that in perspective, Hammyman always beats our 1.5 Peugeot 106 diesel, even his traffic driving beats ours on a steady motorway run!

As I stated on another thread when we were looking for an economical AUTO the real life MPG figures for autos are almost impossible to find. Anyone can drive a manual car very economically, dip the clutch downhill and when slowing down for example.
So anyone else like to post real MPG for an automatic car?

Some Automatic figures I've recorded:

Audi A6 3.0TDI Quattro Auto - 34mpg over 8k miles
VW Touran 2.0TDI DSG - 46mpg over 43k miles
LR Freelander 2 TD4 Auto - 33mpg over 37k miles
Audi A4 3.0TDI Quattro Auto - 42mpg over 3k miles
BMW 330i Auto - 38mpg over 12k miles

If you dip the clutch in a modern car, the engine will still have to burn enough fuel to keep it ticking over. Leave the clutch engaged and employ engine braking and it will use NO fuel at all when slowing.

Exactly taking your foot off the throttle pedal cuts the fuel off, The cars momentum keeps the engine
ticking over. Dont let the revs drop below the normal tickover speed though. Change down a gear or two.

There are no " real life " MPG figures for any vehicle, be it Auto or Manual, we all drive differently.

Coasting with the engine running will not save any fuel.

Well that proves why you're getting such poor MPG - you've not got a clue how to drive economically.

Lets take your method, dipping the clutch going downhill and when slowing. When you dip the clutch, the engine management supplies fuel to keep the engine ticking over so whilst it is coasting, it is using fuel and therefore the distance travelled like this is not free.

Lets take my method - lifting off the accelerator but keeping it in gear and in drive. The engine management cuts off ALL fuel to the engine and therefore the distance travelled like this IS FREE.

I suggest that in future instead of driving right up to something then braking, you try letting off the accelerator earlier. For example when exiting a sliproad off a motorway, if you are doing 70MPH on the motorway and lift off at the 200 metre chevron,you'll have enough momentum to take you to the end of the slip road completely free of charge. Most people however still drive up the slip road and then brake at the end, thus doing half a kilometre or more using fuel where I wouldn't. Likewise when approaching roundabouts, lift off earlier especially if there's a car waiting to get onto it ahead - the aim is to reach the roundabout and be able to enter it without stopping. Same with traffic lights - if they're on red then lift off the accelerator earlier and use the engine braking to slow you and hopefully you reach them by the time they change. Driving up to a roundabout with a car ahead waiting to get on it and then braking won't get you on the roundabout any quicker than coasting up to it in gear. Driving up to a red light then braking won't get you setting off any quicker than if you coasted up to them in gear. One method will use 100% more fuel than the other....

Remember that every time you use your brakes to slow, you've wasted money on fuel turning it into heat. I hardly use my brakes of I can help it because its throwing away money. To illustrate how little I use them, in June I was told they were low and would need changing soon. The MOT advisory in July said the same. LAST WEEK I finally changed them. I'd done 10,000 miles since the service and the brake pads still had 1mm of friction material left. The pads were new when I bought the car and had lasted 60,000 miles. And no, I don't drive slowly.

My Mondeo 140ps with powershift gearbox, which now has 1400 miles on the clock is doing between 35 and 41 mpg. Short trips of under 4 miles drag the MPG figures down big time.
