Market evolution: Large diesel cars (CN 87033319) — 2015–2025

Introduction

This report examines the evolution of EU extra-EU trade in new motor vehicles equipped exclusively with diesel engines of a cylinder capacity exceeding 2,500 cm³ (CN code 87033319) over the period 2015–2025. This product category covers large diesel passenger cars and station wagons — a segment historically dominated by European manufacturers, particularly German premium brands. The decade under review has been one of dramatic structural decline for this niche. EU exports in value terms fell by 82.5% (from €8.66 billion to €1.51 billion), while imports declined by 48.5% (from €5.67 billion to €2.92 billion). EU production of these vehicles collapsed even more sharply, dropping by 59.7% in unit terms. The combination of tightening CO₂ regulations, the post-Dieselgate reputational crisis, the rise of electrification, Brexit, and geopolitical disruptions has fundamentally reshaped this market, turning the EU from a net exporter into a net importer of large diesel cars.

Scope & Definitions

1. A Decade of Contraction: The Structural Decline of Large Diesel Car Trade

The period 2015–2025 is characterised by a sustained and deep contraction in both the volume and value of EU trade in large diesel vehicles. The decline was not a single shock but a progressive erosion, driven by overlapping regulatory, technological, and reputational forces.

1.1 Export volumes fell by over 86% in vehicle terms

EU exports of large diesel cars dropped from €8.66 billion and 198,441 units in 2015 to €1.51 billion and just 27,519 units by 2025 — declines of 82.5% in value and 86.1% in unit count. The export unit price rose modestly from €43,625 to €55,025 per vehicle (+26.1%), suggesting that the remaining export trade has shifted toward higher-value, lower-volume models — consistent with the premium positioning of surviving large-diesel products. However, this price increase was nowhere near sufficient to compensate for the collapse in volumes.

1.2 EU domestic production collapsed alongside exports

EU production of large diesel vehicles fell from 198,455 units (valued at €7.58 billion) to an estimated 80,000 units (valued at €2.0 billion) over the period — a decline of 59.7% in units and 73.6% in value. Production peaked at 419,654 units, meaning the 2025 figure represents barely one-fifth of peak output. This confirms that the trade decline is not merely a shift in trade patterns but reflects a genuine contraction of the underlying manufacturing base for this powertrain type within the EU.

1.3 The Dieselgate scandal and regulatory tightening drove the structural shift

The timing of the decline is instructive. The Dieselgate scandal broke in September 2015, triggering a cascade of regulatory and market responses across Europe: stricter real-driving emissions (RDE) testing from 2017, urban diesel bans in major cities, tightening Euro 6d emission standards, and increasingly ambitious CO₂ fleet targets under the EU's regulatory framework. These measures progressively eroded the economic rationale for large-displacement diesel engines. Meanwhile, the EU's CO₂ fleet-average targets created strong incentives for manufacturers to prioritise electrified drivetrains. The result was a deliberate, industry-wide shift away from large diesel engines, which is clearly visible in both the production and trade data.

2. Brexit, Sanctions, and Geopolitical Realignment: The Reshaping of EU Trade Geography

The contraction of large diesel car trade was not uniform across partner countries. Several major bilateral relationships were disrupted by discrete geopolitical events, while new trade routes emerged partially to fill the gap.

2.1 The United Kingdom's exit from the EU single market devastated bilateral flows

The United Kingdom was by far the most important partner for large diesel cars in 2015. EU exports to the UK stood at €3.79 billion (43.8% of total exports), while imports from the UK totalled €1.63 billion (28.7% of total imports). By 2025, exports to the UK had fallen to €160 million (−95.8%) and imports to just €42 million (−97.4%). While the broader decline of the product category explains part of this, the speed and severity of the UK-specific collapse — far exceeding the average decline — points clearly to Brexit as an amplifying factor. The UK's departure from the EU customs union introduced non-tariff barriers, rules-of-origin requirements, and regulatory divergence that compounded the structural downturn.

A notable price shock in UK imports was detected in 2022, with an abnormality score of 23.3 and a unit price shift of +21.3%, likely reflecting supply disruption and cost escalation during the post-Brexit adjustment and the broader 2022 supply-chain crisis.

2.2 Russian exports collapsed to near zero following the 2022 invasion of Ukraine

EU exports to the Russian Federation fell from €481 million in 2015 to just €82,583 in 2025 — effectively a complete cessation of trade. Russia had been a significant destination for European luxury and premium diesel vehicles. The EU sanctions imposed following Russia's invasion of Ukraine in February 2022, including restrictions on the export of high-value goods and vehicles, explain the near-total elimination of this trade route. This represents a loss of a market that was already declining but still substantial.

2.3 The United States became the EU's dominant import source even as volumes declined

The United States was already the largest import source in 2015 (€3.48 billion, 61.5% of imports) and retained that position in 2025 (€1.67 billion, 57.1%), despite a decline of 52.1%. The US share of EU imports actually increased in relative terms, as other sources contracted even faster. This likely reflects the importance of German premium brands (BMW, Mercedes-Benz) manufacturing large diesel SUVs in US plants (notably in South Carolina and Alabama) and shipping them back to the European market. The coefficient of variation for US import values was 0.49, indicating moderate volatility.

2.4 Japan emerged as the second-largest import source

Japanese imports of large diesel cars into the EU grew by 132.4%, from €362 million to €841 million — the only major import source to show significant growth over the period. This likely reflects the import of vehicles from Japanese transplant factories and the growing role of Toyota's Land Cruiser and similar large diesel models that continued to be produced for markets with strong diesel demand.

2.5 Export concentration became more diversified even as total volumes collapsed

The export HHI fell from 2,317 to 1,169 (−49.5%), indicating that exports became significantly more diversified across destination countries. This is largely an artefact of the collapse in the two dominant export destinations (UK and Russia), which concentrated trade in 2015. In 2025, the remaining exports are spread more evenly across a wider set of smaller markets, including Japan (+217.3% to €360 million), Switzerland (−83.6% to €74 million), Australia (−87.5% to €44 million), and China (−95.8% to €13 million). Import concentration also declined moderately, with the HHI moving from 4,649 to 4,225 (−9.1%).

3. From Net Exporter to Net Importer: Growing External Reliance in a Shrinking Market

One of the most striking structural shifts revealed by the data is the reversal of the EU's trade balance for large diesel cars, combined with a sharp increase in trade openness metrics.

3.1 The EU shifted from a €3 billion trade surplus to a €1.4 billion deficit

In 2015, the EU recorded a trade surplus of approximately €2.99 billion in large diesel cars — a category in which the EU was a clear net exporter. By 2025, this had reversed into a deficit of approximately €1.41 billion. The net import reliance shifted from +20.0% to +41.7%. The reversal reflects the fact that exports declined far more steeply (−82.5%) than imports (−48.5%). While both directions of trade contracted, the EU's competitive advantage in this segment eroded faster than domestic demand for imported vehicles.

3.2 Trade intensity nearly doubled, revealing a more import-dependent market

The EU's trade intensity for this product — defined as the ratio of trade (imports + exports) to apparent consumption (production + imports − exports) — rose from 54.9% to 91.3% (+66.4%). This extraordinary increase indicates that even as total trade volumes fell, the share of the remaining market supplied through external trade (especially imports) grew dramatically. The declining domestic production base means that a much larger proportion of the (smaller) market is now served by non-EU sources.

3.3 Export propensity surged, but in a context of shrinking production

Export propensity — the share of domestic production that is exported — rose from 30.1% to 78.3% (+160.5%). Paradoxically, this occurred alongside a collapse in both production and export volumes. The explanation is that production fell even faster than exports: with EU production at roughly 80,000 units and exports at 27,519 units, a large share of the remaining (small) production is still destined for export markets. However, this high export propensity reflects a residual concentration on export-oriented premium models rather than a sign of health — the absolute volumes involved are a fraction of their former levels.

3.4 Austria and Slovakia emerged as specialised exporters, while Germany's dominance waned

In 2025, the EU member states most specialised in exporting large diesel cars were Austria (RSCA 0.70, RCA 5.78) and Slovakia (RSCA 0.58, RCA 3.75). Austria's export value more than doubled from €212 million to €510 million (+140.4%), and Slovakia's exports, while declining from €769 million to €263 million, remained significant relative to the country's overall trade profile. Germany, which accounted for €6.60 billion in exports in 2015 (76.2% of EU total), saw its exports collapse to €424 million (−93.6%). Germany still accounted for 45.9% of EU production in this category, but its export share has eroded considerably.

On the import side, Germany remained the largest EU importer (€1.87 billion in 2025, down 47.3%), followed by Belgium (€685 million, down 19.0%) and Spain (€207 million, up 53.4%). Italy's and France's imports collapsed almost entirely (−99.4% and −97.7% respectively), and Austria's imports fell to just €623,057.

Conclusion

The EU market for large diesel passenger cars (CN 87033319) has undergone a profound structural transformation over the 2015–2025 period. What was once a €20+ billion combined trade market in which the EU was a dominant net exporter has shrunk to roughly €4.4 billion, with the EU now running a significant trade deficit. The decline was driven by the convergence of multiple forces: the Dieselgate scandal and its regulatory aftermath progressively undermined diesel's market position; tightening CO₂ standards and the electrification transition shifted industry investment away from large-displacement diesel engines; Brexit severed the EU's most important bilateral trade link for this product; and EU sanctions on Russia eliminated another major export destination.

The remaining trade is characterised by higher unit values, greater geographic diversification on the export side, and growing reliance on a small number of non-EU suppliers — principally the United States and Japan — on the import side. Domestic production has been cut by nearly 60%, concentrating in a smaller number of specialised member states (Austria, Slovakia, Germany). The surging trade intensity and export propensity metrics reflect not a healthy, open market but a contracting niche in which external flows represent an ever-larger share of a shrinking pie. Looking ahead, the trajectory is clear: as the EU moves toward its 2035 target of ending sales of new internal-combustion-engine vehicles, this product category will continue to decline, and the residual trade will increasingly consist of premium and specialty vehicles serving diminishing demand.
