Long-haul 6×4 tractor units: which uses the least fuel?

Every model here was simulated by its manufacturer on the EU long haul mission, with the payload the regulation sets, and declared to the regulator. Figures are compared only within one reporting year and one payload. A model is ranked when at least ten declared vehicles stand behind its figure.

Showing the 30 lowest declared figures of 33 ranked here. Every model has its own page, reached from its make or its range.

What the difference is worth

The lowest and highest ranked here are 13 l/100 km apart (44.2%). At 120,000 km a year and an assumed £1.40 a litre, that is about 15,600 litres a year, or £21,840.

Where it stops mattering: 4 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Volvo FH, 375 kW, 6x4 tractor unit alone span 13.8 l/100 km across its configurations.

The price is an assumption for illustration, not a price we track; use your own. Declared figures compare vehicles with each other on a standard route; they are not what one lorry will use on your roads.

Showing the 30 lowest declared figures of 33 ranked here. Every model has its own page, reached from its make or its range.

What the difference is worth

The lowest and highest ranked here are 12.9 l/100 km apart (57.8%). At 120,000 km a year and an assumed £1.40 a litre, that is about 15,480 litres a year, or £21,672.

Where it stops mattering: 3 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Volvo FH, 375 kW, 6x4 tractor unit alone span 12 l/100 km across its configurations.

The price is an assumption for illustration, not a price we track; use your own. Declared figures compare vehicles with each other on a standard route; they are not what one lorry will use on your roads.

What the difference is worth

The lowest and highest ranked here are 9.9 l/100 km apart (29%). At 120,000 km a year and an assumed £1.40 a litre, that is about 11,880 litres a year, or £16,632.

Where it stops mattering: 6 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another.

Showing the 30 lowest declared figures of 34 ranked here. Every model has its own page, reached from its make or its range.

What the difference is worth

The lowest and highest ranked here are 10.1 l/100 km apart (38.6%). At 120,000 km a year and an assumed £1.40 a litre, that is about 12,120 litres a year, or £16,968.

Where it stops mattering: 6 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Volvo FH, 552 kW, 6x4 tractor unit alone span 18 l/100 km across its configurations.

The price is an assumption for illustration, not a price we track; use your own. Declared figures compare vehicles with each other on a standard route; they are not what one lorry will use on your roads.

Showing the 30 lowest declared figures of 32 ranked here. Every model has its own page, reached from its make or its range.

What the difference is worth

The lowest and highest ranked here are 10.7 l/100 km apart (30.9%). At 120,000 km a year and an assumed £1.40 a litre, that is about 12,840 litres a year, or £17,976.

Where it stops mattering: 7 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Volvo FH, 552 kW, 6x4 tractor unit alone span 12.9 l/100 km across its configurations.

The price is an assumption for illustration, not a price we track; use your own. Declared figures compare vehicles with each other on a standard route; they are not what one lorry will use on your roads.

The lowest and highest ranked here are 11 l/100 km apart (41.3%). At 120,000 km a year and an assumed £1.40 a litre, that is about 13,200 litres a year, or £18,480.

Where it stops mattering: 5 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Volvo FH, 552 kW, 6x4 tractor unit alone span 12.3 l/100 km across its configurations.

The price is an assumption for illustration, not a price we track; use your own. Declared figures compare vehicles with each other on a standard route; they are not what one lorry will use on your roads.

What the difference is worth

The lowest and highest ranked here are 8.1 l/100 km apart (23%). At 120,000 km a year and an assumed £1.40 a litre, that is about 9,720 litres a year, or £13,608.

Where it stops mattering: 3 models here are within 10% of the lowest figure, inside the tolerance of declared figures, so the ranking between them is not a reason to choose one over another. The specification ordered matters too: declared figures for the Scania R 540 A6x4 alone span 8.4 l/100 km across its configurations.
