Euro 7 for M1 and N1: battery durability, low-temperature range and system power added to the test methods — system power is measured on a dynamometer according to UN Regulation No 177 at 25 ± 5 °C, recorded at 10 Hz or more
Commission Implementing Regulation (EU) 2026/1764, published on 22 July 2026, amends Implementing Regulation (EU) 2025/1706 — the Euro 7 type-approval test methods for passenger cars and light commercial vehicles. It adds annexes on in-vehicle battery durability (UN Regulation No 154, 04 series), electric vehicle low-temperature range and system power (UN Regulation No 177), and in-service conformity rules from UN Regulation No 83 (09 series).
- Battery durability is tested according to paragraph 6.11 and Annex C1 of UN Regulation No 154 (level 1A), but with the minimum requirements of Annex II to Regulation (EU) 2024/1257. The manufacturer may declare its own requirements (DPR) for two periods: up to 5 years or 100 000 km, and up to 8 years or 160 000 km. Low-temperature range — paragraph 6.10 and Annex B10 of Regulation No 154, only for pure electric vehicles.
- System power of hybrids and electric vehicles with more than one motor — paragraphs 7 and 8 of UN Regulation No 177: two equivalent procedures, TP1 (measured electric power) and TP2 (torque and speed at drive shafts or wheel hubs). Test cell 25 ± 5 °C (23 °C on request), pressure 80–110 kPa, maximum power held for about 10 s.
- Measurement requirements of Regulation No 177: recording at 10 Hz or more; voltage and current ±0.3 % of full scale or ±1 % of reading; dynamometer force transducer ±10 N, verified within 370 days before the test; wheel torque ±6 Nm or ±0.5 % of the maximum measured torque. The efficiency of the inverter and electric machine (K1 factor) is determined according to standards such as ISO 21782 or SAE J2907.
- The manufacturer may declare lower maximum RDE values for NOx and PN10, which then apply in in-service conformity checks and market surveillance. The new ME sub-characteristics (M1, N1) apply to new types from 29 November 2026 and to new vehicles from 29 November 2027; OBFCM requirements for pure electric vehicles — from 1 January 2030.
