Gotta love Tdi economy

[gldgti]

Driving home last night at 7pm (just past peak traffic), mainly on major roads

Even allowing for the worst case of recorded MFD optimism (going by refill/distance vs MFD mileage) of 10%, that's still better than 4l/100km


As well as the other changes, Bluemotion models are lowered vs normal ones.

Good work!

As for the bluemotion cars - I thought they looked a bit lower but I couldnt be sure. I saw a passat bluemotion the other day and htought it looked very sporty indeed.

On EXACTLY the same route, I could only manage an indicated 4.2 l/100km today

Mind you, I was an hour earlier so had to wade through the midst of peak hour traffic

[sparkie]

Best run ever, filled the 1996 Mk3 Tdi to the brim as directed, zeroed the trip counter, ran 1202 kms on a 55 litre tank, equals 4.58 l/100km, I could have gone another 50km or so but I chickened out! Now to try again an economy run - no air con, coasting down hills etc!

Read that a couple in US did an economy run in a stock Mk6 Jetta manual and got 2600km out of a single tank! Well. I tried to drive economically last week in my Mk 5tdi manual and damn all I got was a measly 30km over my 1000km normal range. I didnt turn off airconditioning etc - creature comforts are needed in winter, just made sure I shifted early and in a higher gear and didnt rev hard at all. Back to my normal driving!

I doubt that.
55lt 2600km = 2.11 lt/100k = 133.59 mpg
that is a guiness record

I read years ago a new Land rover Defender130 300TDI in Australia did a record braking trip on 1 fill up something like 1600-1700km... was not till you read that they fitted the factory extra extended fuel tanks giving them 70lt standard tank + 100lt ext tanks = 170 lt... it still averaged 10-11 lt/100km which is the average we all get in them (I have a Defender130)

Thats exactly what it was haha. And it was 84 mpg.

VW Passat Sets World Record for Distance Traveled on a Single Tank | AutoGuide.com News

They were a couple that have been doing efficiency driving records for ages, and it was all certified with a sealed fuel cap et al.

Here's the world record (it was in a Passat)

2012 Volkswagen Passat TDI SE Sets World Record for Distance on One Tank of Fuel

84.1 MPG (US gallons) = 101 MPG (UK gallons) = 2.796 litres per 100 km

Fuel Consumption Calculator


A 2012 Volkswagen Passat TDI SE with the six-speed manual has just set the record for maximum range on one tank of fuel with an astounding run of 1,626 miles. The Passat with the 6MT is officially rated by the EPA at 43 mpg highway, 31 city and 35 combined and has an 18.5 gallon fuel tank. Estimated highway range for the Passat is 795.5 miles.

The trip from Houston, Texas to Sterling, Virgnia took John and Helen Taylor, "The world's most fuel-efficient couple," three days over which they averaged 84.1 mpg. The Taylors swapped drivers frequently and never drove more than 14 hours per day. Assuming they drove exactly 14 hours per day and stopped for a total of 45 min per day, we're looking at an average speed of something like 41 mph. On the highways the Taylors said they did exactly 60 mph. To properly simulate "real" use, the Taylors also loaded the car with 120 pounds of luggage.

The Taylors are self proclaimed driving efficiency experts and hold over 90 fuel economy and driving records around the world and have made a living from conducting fuel-efficient driving workshops.

Previously the record was held by a VW Passat 1.6 BlueMotion diesel in Europe.

Yep, thats the one! That is a ridiculously low amount of fuel used for the distance covered! Two up with 120 lbs of luggage and at 60mph average!

"Self proclaimed" - and rightly so I reckon

Thats awesome.

I got a 982/tank in the octy last week.... thats pretty good for my weekly rout. Also, there was a 300km chunk of that tank where I had 6x 4.8 sticks of 90x45 framing timber AND 7 sheets of zincalume corrugated steel roofing sheet on the roof racks

Trying to think what they could have done to decrease their consumption (besides the usual techniques). Drive only on flat interstate highways. Wait for a tailwind. Ask around at a truckstop diner for a truck going a long way that you could draft behind (or do it anyway).

I've got 5.5 at 110kmph easy in my car which is the PD version of their engine (in a Skoda wagon 4x4). I could see getting 4-4.5 at 100kmph if I was a bit careful, so being extremely careful I could imagine it feasible to get low to mid 3's.

Here's their site:

They used a special fuel on a round the world trip (and used 'Shell Ultra Low Sulfur Diesel' on the US trip).

'The Taylor’s car ran exclusively on fuel containing our new Fuel Economy Formula which contains a Synthetic Viscous Friction Improver, formulated to help reduce friction right at the heart of the engine, helping minimise energy waste.'

They got 3.13 in a Peugeot 308 HDi Diesel round Australia.
