Yesterday for about 1hr 20mins I had a lovely little chance to hypermile my friends new Econetic Fiesta. This was the first time that I had the chance to hypermile a diesel as the car I have for driving instruction is a pathetic Vauxhall Corsa (GM btw..) who drinks more petrol than an alcoholic stuck inside a booze warehouse.
I wasn't overly scientific about the test (unfortunately) as it was a spur of the moment kind of thing, but we had some time to kill and he suggested I'd give "all that hypermiling kerfuffle" a go in his new baby. I wish I had my cellphone with me to get a picture of the trip computer at the end of it because I was pretty impressed!
Route distance was 29.4 miles with about 11 miles of that being on the motorway. Roughly about 10 miles of it was on A and B roads and the rest was stop and go busy weekend traffic. The tires were fully inflated to the max on the side wall (They were 15 psi short of the max! :eek: ) Techniques used was P&G, High Speed P&G, FAS (where appropriate), proper timing of traffic signals, DWL and DWB (very fun!)
The Driving Standards Agency is strongly against coasting but after seeing the benefits of it, it truly is an incredible and valuable fuel saver. I believe the DSA here is wrong now to teach against coasting. If you coast on your driving test here 3 times, you fail your test. The new fiesta really likes to roll alright and she can go quite far when coasting! And was particularly fun to do it on the motor way. After a few miles or so of playing with high speed P&G (50mph down to 40 mph) I decided to go up to 55 and then pull her into neutral. Well I didn't have to step on the gas AT ALL for the rest of the motorway part of the route, the car just kept going and going (down a very shallow hill) and my friend was stunned at what he was seeing, we went all the way up to 60 in neutral and the only pedal I had to touch was the brake when we were going too fast. Overtaking people in neutral was quite incredible! :D The next time she was in gear was when i moved into second for the roundabout then hit a busy "A road" doing P&G from 40 mph to 30mph.
The good bit:
For a car rated 73.6 mpgUK (61.3 mpgUS / 3.8 L/100km) I got an incredible 112.1 mpgUK (93.3 mpgUS / 2.5 L/100KM)
Exceptional! Which I'm sure is due to the long coast on the motorway and by staying in 5th gear above ~32mph
My friend couldn't believe it, and was quite literally absolutely stunned by it all and loved it! Especially DWB ;) Except that time he banged his head off the window because of it! :D
