Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
There are outstanding changes not yet made to Commission Regulation (EU) 2017/2400. Any changes that have already been made to the legislation appear in the content and are referenced with annotations.
Revised legislation carried on this site may not be fully up to date. Changes and effects are recorded by our editorial team in lists which can be found in the ‘Changes to Legislation’ area. Where those effects have yet to be applied to the text of the legislation by the editorial team they are also listed alongside the legislation in the affected provisions.

The standard torque losses for axles are shown in Table 1. The standard table values consist of the sum of a generic constant efficiency value covering the load dependent losses and a generic basic drag torque loss to cover the drag losses at low loads.
Tandem axles shall be calculated using a combined efficiency for an axle including drive-thru (SRT, HRT) plus the matching single axle (SR, HR).
Generic efficiency and drag loss
Basic function | Generic efficiencyη | Drag torque(wheel side)Td0 = T0 + T1 * igear |
---|---|---|
Single reduction axle (SR) | 0,98 | T0 = 70 Nm T1 = 20 Nm |
Single reduction tandem axle (SRT) / single portal axle (SP) | 0,96 | T0 = 80 Nm T1 = 20 Nm |
Hub reduction axle (HR) | 0,97 | T0 = 70 Nm T1 = 20 Nm |
Hub reduction tandem axle (HRT) | 0,95 | T0 = 90 Nm T1 = 20 Nm |
The basic drag torque (wheel side) Td0 is calculated by
Td0 = T0 + T1 * igear
using the values from Table 1.
The standard torque loss Tloss,std on the wheel side of the axle is calculated by
where:

Standard torque loss at the wheel side [Nm]
=
Basis drag torque over the complete speed range [Nm]
=
Axle gear ratio [-]
=
Generic efficiency for load dependent losses [-]

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
