The following published data consists of combined (that is, average) fuel consumption figures derived from data collected during Type Approval test cycles on empty passenger vehicles, so they have little or no value in the "real world" - they are used merely as reference points to compare with other vehicles.

This data applies to M1 type passenger vehicles (which includes all heavy passenger cars which fall into the N1-111 group - until September 2009 when they revert to class M1 (!)) - that is Caravelles, Multivans, Multivans (with elevating roof)...

... and Transporter Window Vans that are not classed as Light Duty Goods Vehicles for Car Tax Purposes, yet they remain so for London LEZ purposes.

The methods of collecting this data have changed slightly down the years, so this is a guide only - in the real world some driver's may achieve better fuel economy but some may not...

Diesel Caravelle / Multivan / Window Van models


  • TDI - 7.3l/100km (38.5mpg)
  • TDI - 7.9l/100km (36mpg), Syncro 9.8l/100km (28mpg), Auto 8.7l/100km (32mpg)
  • TDI - 8.1l/100km (35mpg)
  • 1.9TD - 8.3l/100km (34mpg)
  • 2.4D na - 9.3l/100km (30mpg - AAB without catalyst), Syncro 10.8l/100km (26mpg), Auto 10.9l/100km (26mpg)
  • 2.4D na - 9.4l/100km (30mpg - AJA with catalyst), Auto 10.0l/100km (28mpg)
Petrol Caravelle / Multivan / Window Van models

  • 2.0 - 12.6l/100km (22mpg)
  • 2.5 - 12.8l/100km (21mpg - AAF / Digifant efi), Syncro 12.7l/100km (22mpg), Auto 13.5l/100km (21mpg)
  • 2.5 - 12.6l/100km (22mpg - AET / Simos efi), Syncro 12.6l/100km (22mpg), Auto 13.4l/100km (21mpg)
  • 2.8 - 11.8l/100km (23.5mpg - 12v VR6), Auto 13l/100km (21mpg)
  • 2.8 - 13l/100km (21mpg - 24v V6 Auto)
These fuel consumption figures, applying to N1-11 and N1-111 Transporter Panel Vans (tested at a constant 90km/h at half payload), are for comparison purposes only.

Diesel Panel Van models

  • TDI - 7.7l/100km (36.5mpg), Syncro 8.7l/100km, Auto
  • TDI - 7.9l/100km (36mpg)
  • 1.9TD - 8.3l/100km (34mpg)
  • 2.4D na - 9.3l/100km (30mpg - AAB without catalyst), Syncro, Auto
  • 2.4D na - 9.4l/100km (30mpg - AJA with catalyst), Auto
  • 1.9D na - 8.1l/100km (35mpg)
Petrol Panel Van models

  • 1.8 - ? no data as yet
  • 2.0 - 11.2l/100km (26mpg)
  • 2.5 - 11.9l/100km (23.5mpg - AAF / Digifant efi), Syncro, Auto
  • 2.5 - 12.2l/100km (23mpg - AET / Simos efi), Syncro, Auto
Please note that MPG figures are rounded up and down (as they are in the UK brochures)

Interesting comparisons here but my experience is different.
2.4d expect 35 to 40mpg
1.9td similar range to 2.4d
2.5tdi 35 to 45mpg

Just done slightly over 600 miles on a full tank which is about 35mpg I think. I have a 2.4 syncro. First time I've filled it fully, relatively impressed. What can be done to improve economy? De-cat, filters, injectors?

1089 km on 77,3 liters of diesel - 14.09 km/l.

Total of 350 km highway with 110 km/h.
And 719 km of countryside road with 60-80 km/h.

Nope. Fill up tank run until fuel light comes on and fill tank again. See how many liters you replaced and work out mpg from that. No guess work.

my system is to zero the trip when the fuel light comes on then put 10 gallon in (45.43?) litre then next time fuel lite comes on divide by ten, simples:)

I am in no doubt that the rerooved camper is more economical now...



It's a 1.9TD with some tweaks but now drinks a lot less without the high top...

34mpg normal driving /44mpg on the motorway

Mine is a 1.9D 1993 with 90000 on it. Its a trooper motorhome. I just wondered if you are technical enough to work this out for me:

I did 200 miles :confused:on £30 using 133.9 litres. How many miles to gallon. I do approx. 50-60 an hour.

Many thanks
Dennis

According to Fuel-economy.co.uk: Your real-world MPG average is 40.58, covering 200 miles using 4.93 gallons of fuel

Coming to this thread late but I have a heavy California poptop 102 and I was getting a about 7.5 l/100km average combined for all journeys. I have now had the injectors upgraded and I am now getting about 6.4l/100km combined. I Did a 50 mile journey on A and B roads last week and it came down to 4.9l/100km with standard driving, nipping along steadily - was astounded! :db

2001 2.5 Tdi 151 - average 8l/100km, which I am reliably informed is 35.3 mpg.

PS Dennis: 113 litres to do 200 miles works out at 6.7 mpg (about the same as a Volvo tractor unit). You sure about those figures?

What injectors do you use?

I have the PP1 injectors from Rake.
I need a second remap for them as the first didnt work so well - they are difficult to map correctly without a rolling road apparently.

Normally get around 32 - 35mpg out of my rocketship-mileage 2.5TDI (using the longhand method of working it out using science); but did a 700-mile round trip to Newquay from Lancashire the other week and it averaged 42mpg! Fairly sure I could have got there and back on one tank if I'd have set my mind to it.
