Superb Greenline- 70mpg breakthrough!

Postby Veloplus » Mon May 21, 2012 7:24 pm

It's a little while since I've posted on the forum.

After a concerted effort, my seven month old Superb Greenline Combi has managed to break the 70mpg barrier. To be precise, the car achieved 72.96mpg, some 3.1mpg better than my previous best.

If I'd run the tank almost dry, I estimate I'd have achieved 960+ miles from the full tank (60 litres/13.20 litres).

My current Spiritmonitor fuel economy average is 64.5mpg. The target is to 'overtake' a Superb 1.9Tdi Greenline at the head of the table with an average of 65.31mpg. For the present, I'll have to be content with driving the most economical Superb 1.6Tdi Greenline.

An absolute result there - esp for a barge.

You finding any particular technique that's working best for you? With the summer weather on its way (hopefully! :D :D ) you'll soon see even more of an improvement.

Brilliant result VP :D My car isn't a barge but it's a bit of a brick :lol:
I'm still number 1 for every FRV on Spiritmonitor (and Fuelly but not many on there!). I'm hoping to crack 750 miles soon (my tank is 58 litres - the most I've put in is 55).
You can do it!

Excellent result!
What's the official combined figure?

So that last fill has taken your long term average above combined figure - well done!
Your last fill was +13.6%. Next target 73.83mpg for +15% ;)

Nicely done.
The best thing about hypermiling...apart from saving money, saving fuel and reducing emissions...is putting one over on those people who say official MPG figures are unattainable.
Cheers.

Absolutely! I'm consistently getting 30+% over combined figure now. It's taken a while though!

Gents,

Thanks for you kind words.

I find that neutral coasting down steep motorway hills gives a small mpg gain, while lifting off and in-gear coasting to junctions/roundabouts is another beneficial measure.

When travelling on motorways I regularly draft lorries travelling at between 52-55mph, but always maintaining a two second stopping distance.

Today I broke another economy record, that is the most miles travelled on a tank of diesel. My Superb has a 60 litre (13.20 gallon) fuel tank which today enabled me to cover 933.60 miles, some 25.80 miles greater than my last best range figure of 907.80 miles. I should add that this figure was achieved by taking the needle some 51.60 miles past the "0 miles range" notice displayed on the trip computer. I usually safely reckon on an easy 50 miles past zero range, especially if I'm driving on a motorway at a consistent speed.

I was nowhere near a source of cheap fuel, therefore, I refilled from a 10 litre can carried for roadside refueling.By my reckoning, even assuming 13.20 gallons was required to brim the tank, the mpg for my last tankful results in at least 70.73mpg. In reality, I reckon I still had a litre or two, therefore, this would actually improve the already impressive mpg figure.
