Help needed with this please?

4 posts in this topic

Hi there,

I need some help / advise with the following...

I have a VW Tiguan 2.0ltr TDI Auto and want to know the best speed to do to get the best MPG?

I did this test the other day and just wanted to know what you guys thought?

I drove from North Wales to Manchester, the route was very flat and I used my cruise control most of the time set at 60mph.

I took this route....A487, A55, M53 and M56.

The average MPG on my computer hit 47.5 mpg.....Is this good?

What is the best speed to do to get the most MPG out of my car?

Please can anyone help / advise?

Cheers for now.

Ade.

I would have thought you'll get more out of it as you put miles on the car and the engine loosens up. Cruise is not a good way to drive efficiently however it is a good way of stopping the speed from creeping up on motorways and dual carriageways!

If I'm driving economically I stick to every speed limit and look far ahead for hazards, junctions, roundabouts etc. If I'm approaching a situation when I know I'll need to slow down or stop, I often try to negotiate whatever it is without using the brakes. If you keep telling yourself that, you'll be surprised how much more you use the engine and gears to slow down (a modern engine isn't using any fuel when it's in gear and you are not touching the accellerator) and how much more the economy goes up.

The other key thing is to keep a good distance from the car ahead so when they brake, you don't have to, you just need to let off the accellerator. Try it for a couple of days and see how much you save!

56mph, keep the gear selection away from the S mode, avaoid heavy acceleration, you want the tiguan to get into top gear asap.

However 47.5 is very very good from an auto!!!!

ditto.

Results in 55 - 60 mpg on my commute. I sit at about 70 - 80 on the A1, approach roundabouts and try not to have to stop, use ALL the available road so as not to have to slow down on corners/roundabouts if possible. I change up at about 2000/2500 rpm.

As Shark says, leave a gap so you don't have to brake and re-accelerate.

Cruise is bad for MPG - it uses more juice as you go up hills to keep your speed, and then retards the engine when going down the otherside, so you do not benefit from that potential energy. Use it on the flat, then you'll save fuel.
