Hypermiling was mentioned in the badly modified cars thread which led me here:

https://www.hypermiler.co.uk/forum/viewtopic.php?f...

The second poster with the jazz made me chuckle, surely this is the antithesis of pistonheads?!

I used to do it when I got my first proper job and was commuting daily 120 mile round trip (for a £19k a year job (I was a retard))

Best I managed was a genuine 78 mpg tank average, that was in a 2002 Focus TDdi Estate.

Yes, it's very boring.

To be fair to the hypermilers, I tried it out a few times. Doing 50mph on the motorway in my Impreza resulted in a gain of 8mpg but was extremely boring. Being sensible in my Jaguar lasted until the engine was warm. It was very boring as I don't care about the extra 0.01 miles I get because I changed gear before a hill. That said, I'm sure hypermilers have a hatred for people who exceed 1200rpm - horses for courses etc. This perhaps isn't the right forum for eco-warriors.

I’m not judging them, (well maybe a bit) but it always really annoys me when someone slows because of a hill when it’s safe to maintain speed. I had never even considered that it could be deliberate!

Pissing off all the hgv drivers!!!!

Deliberately going nearly 25% under the speed limit to save pennies is selfish and an inconvenience to others.

Wouldn't call it selfish motorways have a lane for overtaking.

I don't really care for my cars mpg because I don't drive it enough but people trying to save money and putting out less co2 are hardly being selfish.

Granted 60mph would be more reasonable to not hold up HGVs but it's hardly selfish.

When I worked in Shirley, in the 1990s there was a bloke that travelled daily from Telford in an Astra Diesel. Not sure if Turbo or not.
He plotted his fuel consumption on an SPC chart, and one day was pissed off to fund that he'd achieved less than 70 mpg.
Basically, never accelerate, never brake, knock it into neutral if there's a bend or junction coming up and coast to it, never go over 50 mph, never go over 2000 Rpm in any gear. Never use engine braking.
Also his journey was before the Toll Road or smart motorways, on M42, M6 and M54.
So turn off the engine if stationary. Always know which lane is most likely to be moving and be in it. He said that he'd done the journey so many times, he knew when.to change lanes.

I tried it for 2 weeks out of curiosity and it was odd, but wouldn't say boring. Coming up to roundabouts, you were trying to avoid actually stopping, without extra acceleration to slot in.
I think my petrol mk2 cavalier went from 32 mpg to 38 mpg, but it took me ages to get anywhere.

At least this has a goal, to save as much as possible. A lot on the site go for a drive with the sole aim of getting as high mpg as possible. Several have an Octavia vrs as well...

I spent a fair amount of time on ecomodders back in day when I had a Skoda Fabia 1.9 TDi. It was never going to be a sports car, so worth playing to its strengths...

I never drove that slowly though, but I did apply the other methods and blocked about 70% of the grill during the winter to improve aerodynamics and getting upto temperature faster. It made a 3 MPG difference across a tank. Rhino fuel additive (cetane booster) was useful too.

I've got a 911 and a Golf TDi. The Golf is fun to drive as economically as possible, otherwise what is the point. It's averaging 63.4mpg currently. The 911, 17mpg...

If the Police see you driving at 50mph on the motorway I imagine they will pull you over. Driving too slowly is dangerous as well!

I think the guys on the hypermilimg forum really take it a step too far! Don't get me wrong, I get that trying to hit good mpg takes a lot of thought and if I'm not in a rush I'm happy to stick the car in Eco Pro and try and break the 50mpg barrier (don't know why but 50mpg always seems like the target), but those guys seem to be on a different level.

I tried it once on the M25 on a long tedious journey in my ex's Merc B class diesel. 60mpg. It usually managed 50 on that journey. My greatest "victory" was in my 1998 Jeep Grand Cherokee 4.0 petrol on a series of roundtrips from north London to Gloucester. If I could hit 20 mpg it was a win!

"When I get home in my car, I drive past the end of our drive at right angles, turn engine off and reverse (roll) round the corner and back then stop at the top of the drive. I take my belongings into the house and then making sure the garage door has opened wink (remote!) I handbrake off, give an extra push with right foot out the door, close door and roll backwards down the slight hill on our drive straight into the garage (with judicious use of both mirrors to line it up) with just enough momentum to go all the way in with just a slight application of the brakes."

That is some dedication right there.

The odd bit of hypermiling can make a trip a bit more interesting particularly if you have a mpg readout. Squeezing out that extra 0.1 mpg is strangely appealing.

On motorways, getting tucked up behind a 56 mph HGV doesn’t piss anyone off and helps with the aero and drag.

If you're driving so slow (out of choice, not necessity) that HGVs have to overtake you, that's selfish behaviour.

When I first saw the title to this thread I thought it was for people who do speed flour milling for bread making.

I knew that people keep mpg spreadsheets but pushing your car in and out of a garage to save fuel that’s a bit extreme.
