Design activity will grow in sensing, power and monitoring systems across the automotive sector, so expects global component supplier, Mouser, due to the tightening Euro 7 vehicle emissions standards. The new rules will apply in the European Union (EU) to all new types of passenger cars and vans from 29 November 2026, and to all newly sold light‑duty vehicles from 29 November 2027, before extending to lorries and buses from 2028. Manufacturers outside the EU will need to comply if they want to sell new vehicles into the EU market.
“As manufacturers move towards the 2026 and 2027 milestones, we expect to see more design activity around precision sensing of exhaust and non‑exhaust emissions, robust power management for emissions systems, and on‑board monitoring solutions that can maintain accuracy over significantly longer lifetimes. Euro 7 compliance will be heavily driven by advanced electronics and real-time vehicle monitoring technologies,” said Mark Patrick, Director of Technical Content at Mouser Electronics.
According to Mouser, three areas are likely to see particular focus as engineering teams adapt existing platforms and develop new models for Euro 7: Exhaust and after-treatment control, brake and tyre particulate emissions, and battery durability and on‑board monitoring. These will call on high‑accuracy sensors, automotive microcontrollers, power management ICs, electronics for measuring and managing brake dust and tyre wear, more sophisticated monitoring of battery health, energy flows and system diagnostics in hybrid and electric vehicles, and a lot more.
“Engineers now have to design electronics that not only hit tighter particulate and monitoring requirements but also stay in specification for much longer in harsh conditions. That creates challenges around component selection, thermal management and robustness – and it’s an area where access to a broad, up‑to‑date portfolio of automotive‑grade components and design resources becomes increasingly valuable,” said Patrick.
