Market evolution: Diesel cars (CN 870333) — 2015–2025

Introduction

This report examines the trade dynamics of the European Union in high-capacity diesel passenger vehicles (CN 870333 — cars with diesel engines exceeding 2,500 cm³) over the period 2015–2025. The product category covers a range of vehicles from large sedans and SUVs to motor caravans, all powered exclusively by large-displacement diesel engines. The period under review is shaped by three converging forces: tightening EU emissions regulation (culminating in Euro 6d standards), the fallout from the 2015 Dieselgate scandal, and the accelerating electrification of the European car fleet. As the data reveals, these factors have produced a structural contraction in both EU production and trade in this segment.

1. A Decade of Contraction: The Collapse of Large-Displacement Diesel Trade

The most striking feature of the 2015–2025 period is the sheer magnitude of decline in both exports and imports of large diesel cars. The EU moved from a position of strong net exporter to one of modest net deficit.

1.1 Exports fell dramatically in both volume and value

EU exports of CN 870333 vehicles collapsed over the decade:

Trade overview

The decline was not a sudden shock but a persistent erosion: export volumes fell nearly every year, with notable accelerations around 2018–2020 as Euro 6d regulations tightened and diesel's market share began to decline structurally. By 2025, the EU exported fewer than one-quarter of the vehicles it shipped abroad in 2015.

1.2 Imports declined more moderately, reshaping the trade balance

While import values also fell significantly, the decline in vehicle count was comparatively modest at −10.8%. This divergence is explained by a sharp decline in the average price per imported vehicle (from ~€37,000 to ~€21,800), suggesting a shift toward lower-priced models or a growing share of used vehicles in import flows.

1.3 The EU shifted from surplus to deficit

The trade balance in CN 870333 swung from a surplus of €3.68 billion in 2015 to a deficit of €1.03 billion in 2025 — a reversal of nearly €4.7 billion. This marks a fundamental change: the EU was once a major net exporter of premium large-displacement diesel vehicles; by 2025, it was a net importer.

The net import reliance rose from 17.4% to 22.8%, confirming that the EU's domestic market became more dependent on external supply relative to its own production capacity.

2. Geographic Reconfiguration: Brexit, Russia, and the Rise of Japan

The collapse of overall trade volumes masked profound shifts in partner composition. The geographic structure of EU trade in CN 870333 was reshaped by geopolitical events (Brexit, sanctions on Russia) and evolving competitive dynamics.

2.1 The UK–EU trade corridor collapsed after Brexit

The single most dramatic geographic shift was the near-total evaporation of trade between the EU and the United Kingdom:

Top partners — exports | Top partners — imports

The UK was formerly the EU's largest export destination for large diesel cars, accounting for over 40% of export value in 2015. Post-Brexit customs arrangements, rule-of-origin requirements, and diverging regulatory frameworks (including the UK's own Zero Emission Vehicle mandate) contributed to this dramatic decoupling. The UK was also a major supplier to the EU; this channel likewise contracted to negligible levels.

2.2 Russia: total export collapse following 2022 sanctions

EU exports to Russia fell from €492 million in 2015 to just €83 thousand by 2025 — effectively a complete cessation. The sharpest drop occurred between 2021 and 2022, coinciding with EU sanctions imposed following Russia's invasion of Ukraine. Russia had been a significant market for European luxury diesel vehicles; this market was effectively closed.

2.3 Japan emerged as a key growth partner

Against the backdrop of declining overall trade, Japan stood out as a notable exception:

Japan's growing role as a supplier may reflect the re-export of vehicles manufactured by European brands' Japanese transplant factories, or the growing presence of Japanese-market diesel vehicles meeting EU specifications. The bilateral growth suggests a deepening trade relationship in this segment even as the overall market contracted.

2.4 The United States remained the top import source

The United States was consistently the EU's largest source of imports, though volumes declined from €3.49 billion to €1.68 billion (−51.9%). This likely reflects imports of vehicles manufactured by European brands (BMW, Mercedes-Benz) at their North American plants and shipped back to Europe. Mexico also grew as a sourcing origin (+1,373%), possibly reflecting BMW's and Audi's expanding Mexican production facilities.

2.5 Export market concentration decreased sharply

The Herfindahl-Hirschman Index (HHI) for exports fell from 2,066 to 837 (−59.5%), indicating a significant diversification of export destinations. While this might appear positive, it is largely an artefact of the collapse of the dominant UK market — smaller markets now constitute a larger share of a much smaller total.

3. EU Production Decline and Internal Specialisation Shifts

The contraction in trade was mirrored by a substantial decline in EU domestic production, and the internal geography of production within the EU also shifted.

3.1 EU production halved over the decade

Production volumes

Production peaked in 2018 at 439,654 vehicles (€15.9 billion) before entering a steep decline that was accelerated by the COVID-19 pandemic in 2020 and the subsequent regulatory push toward electrification. By 2025, output was roughly half its 2015 level.

3.2 New vehicle exports bore the brunt of the decline

The product segment breakdown reveals that new passenger vehicles (CN 87033319) — which dominate the category — saw the most severe export decline:

Product segment comparison

Notably, used vehicle exports (CN 87033390) remained remarkably stable at around 26,000 units per year, even as new vehicle exports collapsed. This suggests a growing relative importance of the used-vehicle export trade, possibly driven by the disposal of older diesel vehicles from the EU fleet. Meanwhile, the unit price of exported new vehicles rose from €43,625 to €55,025 (+26.1%), indicating that what remains of the export trade is concentrated in higher-value, premium models.

3.3 Germany's dominance eroded; Austria and Slovakia gained ground

EU reporter specialisation

Germany remained the EU's largest producer and exporter of large diesel cars, but its dominance declined sharply:

Austria's export growth — bucking the overall trend — likely reflects its specialised production base (e.g., the Magna Steyr contract manufacturing facility in Graz). In terms of revealed comparative advantage (RCA), Austria (RCA 5.01) and Slovakia (RCA 2.95) were the most specialised EU producers in 2025, followed by Germany (RCA 2.12).

On the import side, Germany was also the largest EU importer (€1.89 billion in 2025), consistent with its role as both a major producer re-importing from overseas plants and a large domestic market for premium diesel vehicles. Italy and France, however, saw import declines exceeding 95%, consistent with the sharper regulatory and market rejection of diesel in those countries.

3.4 Price shocks were detected in export trade

The volatility analysis identified two notable price shocks in EU exports:

• South Korea (2021): An abnormal price shift of +26.5% (abnormality score 5.7), representing 12.1% of export value. This may reflect supply constraints during the post-COVID semiconductor shortage, which disproportionately affected vehicle shipments.
• Belarus (2022): A +32.0% price shift (abnormality 4.4), representing 3.0% of export value, coinciding with the onset of sanctions-related trade disruptions.

Supply shock events

The United Kingdom exhibited the highest overall export volatility (coefficient of variation of 0.97), a direct reflection of the structural break caused by Brexit.

Conclusion

The period 2015–2025 witnessed a profound structural decline in EU trade of large-displacement diesel passenger vehicles (CN 870333). Export volumes fell by over three-quarters, and the EU's once-robust trade surplus in this category swung into deficit. This decline was driven by the convergence of regulatory tightening, reputational damage from the Dieselgate scandal, accelerating electrification, and the disruption of key trade corridors — most notably the near-total decoupling from the United Kingdom following Brexit and the cessation of exports to Russia after 2022.

Within the EU, production consolidated around specialised hubs in Germany, Austria, and Slovakia, while the used-vehicle export segment proved surprisingly resilient. Japan emerged as an increasingly important bilateral partner, and average export unit values rose, suggesting that the remaining trade is concentrated in the premium segment. As the EU advances toward its 2035 ban on new internal combustion engine vehicles, the market for large diesel cars is likely to continue its structural contraction, with trade increasingly limited to niche applications and used-vehicle flows.
