Quick Answer
How will electric vehicles impact the EGR industry? Electric vehicles do not require EGR systems, but the transition will take 15-20 years. By 2030, EVs are projected to hold 30% market share while 70% of vehicles will still use internal combustion engines requiring EGR components. The EGR aftermarket is expected to grow until 2035 before gradually declining as ICE vehicle production decreases.
Electric vehicle adoption is accelerating, but the EGR valve aftermarket has at least 10 years of strong demand ahead. This analysis separates the EV hype from the data that actually matters for sourcing decisions.
EV adoption timeline
| Year | EU EV market share | Diesel market share | Gasoline share |
|---|---|---|---|
| 2020 | 10.5% | 28% | 48% |
| 2022 | 21.6% | 16% | 37% |
| 2024 | 13.6%* | 13% | 36% |
| 2026 (proj) | 20-25% | 10-12% | 35-38% |
| 2030 (proj) | 40-50% | 5-8% | 30-35% |
| 2035 (proj) | 70-80% | 2-5% | 15-25% |

Diesel vehicle parc projection
The key metric is not new sales share — it is the installed base (parc) of diesel vehicles on the road:
| Year | EU-27 diesel parc | Avg age | EGR parts demand |
|---|---|---|---|
| 2024 | ~108 million | 9.2 yr | Peak |
| 2026 | ~110 million | 9.5 yr | Peak+ (aging) |
| 2030 | ~95 million | 10.5 yr | Strong (old vehicles need more parts) |
| 2035 | ~70 million | 11.5 yr | Moderate |
| 2040 | ~40 million | 12+ yr | Declining but significant |
Even in 2035, there will be ~70 million diesel vehicles needing EGR parts. The parc ages (good for aftermarket) even as it shrinks.
Risk by segment
| Segment | EV risk | Timeline | EGR demand outlook |
|---|---|---|---|
| Passenger car (new) | High | 2026-2035 | Declining from ~2030 |
| Passenger car (aftermarket) | Low | 10-15 years | Strong through 2035+ |
| Light commercial | Medium | 2028-2035 | Strong through 2032+ |
| Heavy truck/bus | Low | 2035-2045 | Strong through 2040+ |
| Off-highway/agri | Very low | 2040+ | Strong indefinitely |
Remaining opportunity
Three reasons the EGR aftermarket remains strong:
- Aging parc: Older vehicles need more replacements. A 10-year-old diesel is in peak EGR failure window. The average diesel age is increasing (9.2 → 10.5+ years by 2030).
- Euro 6 wave: Vehicles sold 2015-2020 (peak diesel Euro 6 production) are now 5-10 years old, entering the 60,000-100,000 mile failure window. This is the largest single cohort of high-EGR-rate vehicles ever built.
- Commercial vehicles: Heavy trucks, buses, and off-highway equipment will remain diesel-dominated for 15-20+ years. Their EGR systems are larger, more expensive, and fail more frequently.
Conclusion
The EGR aftermarket is not declining — it is shifting from new-vehicle to aftermarket-driven. The next 10 years represent the peak replacement demand window, driven by the Euro 6 cohort aging into the failure zone.
For sourcing strategy: maintain EGR valve and cooler supply chain through at least 2032. Begin diversifying into adjacent categories (thermal management, cooling system, fuel system) around 2028-2030 to prepare for long-term EV transition.

Frequently asked questions
When will EGR valve demand actually decline?
Around 2030-2032 for new-vehicle production. Aftermarket demand remains strong through 2035+. Heavy commercial through 2040+.
Should I exit the EGR parts business?
No. The next 10 years are peak replacement demand. Plan diversification around 2028-2030, but EGR remains a strong category.
Will hybrid vehicles need EGR valves?
Yes. Hybrid vehicles still have combustion engines. Most hybrids use the same EGR systems as conventional vehicles.
How big is the commercial vehicle EGR market?
Commercial vehicles represent approximately 30% of EGR parts demand by value, with longer service life and higher per-unit cost.
