Fuel efficient cars at 140km/h

[TillyC]

Hi!

I realise I might be opening a can of worms but here goes. I may have to commute 300km 3 days a week (900 total) and I'm looking to buy a petrol car (as that's what is available where I am) that is fuel efficient at 140km/h.

140 is the speed limit here, and it can be dangerous (and annoying) to go slower... if you've driven in the Middle East you'll know what I mean.

I'm open to tuning the right car to find the right balance, but any tips of where to start is appreciated.

To be clear, there are no diesel or hybrids on the market here, and a Tesla is too expensive for me.

About 260km of the journey will be done at 120-140km/h.

Thanks!

I would have thought that with the price of petrol in UAE that economy would not really be an issue. Get a car with low drag (estates are supposed to be good). Keep the tyre pressures up a bit above the manufacturer's recommendations and use a light throttle (don't be in too great a rush to get to 140kph).

You would think eh! The petrol prices have jumped massively here and with the high cost of living, saving some money at the tanks is very much at the front of my mind right now!

Hello from our left coast...........

FWIW - here's my take on fuel efficiency at 85 MPH.

I have a HIGH MPG 4 cylinder turbo VW with a clutch and a 5M.

On a recent run to connect with a US Navy amigo - I drove about 150 miles on 2.85 gallons.

You need more - MHO - to get great fuel numbers at the higher speeds.

Wish I had better info 4U.
