Market evolution: Spark-ignition engines (CN 8407) — 2015–2025
Introduction
The European Union’s external trade in spark-ignition reciprocating or rotary internal combustion piston engines (CN 8407) between 2015 and 2025 tells a story of striking price growth, major geographical reorientation, and significant structural change within engine categories. Over the period, the EU preserved a sizeable trade surplus while absorbing dramatic shocks, notably the near‑disappearance of Russia as an export destination and the post‑Brexit realignment with the United Kingdom. The following three sections examine the main dynamics visible in the data, all of which can be explored via the interactive trade dashboard.
1. Diverging Trends in Value, Volume and Price: The Premiumisation of EU Engine Trade
Export and import unit values increased by more than a third, offsetting sharp volume declines
The EU’s engine trade became markedly more “premium” during the decade. While export quantity fell by a quarter (–25.1 %) and import quantity by a fifth (–20.6 %), total values actually rose or held steady thanks to steep price increases. Export unit prices jumped 36.3 %, from €13 803 to €18 812, and import unit prices rose 30.8 %, from €12 675 to €16 583.
| Flow | Value (first) | Value (last) | Δ Value | Quantity (first) | Quantity (last) | Δ Quantity | Unit price (first) | Unit price (last) | Δ Price |
|---|---|---|---|---|---|---|---|---|---|
| Exports | €6 254 M | €6 384 M | +2.1 % | 453 096 items | 339 347 items | –25.1 % | €13 803 | €18 812 | +36.3 % |
| Imports | €2 724 M | €2 831 M | +3.9 % | 214 890 items | 170 704 items | –20.6 % | €12 675 | €16 583 | +30.8 % |

The EU’s trade surplus remained remarkably stable at around €3.5 billion
Despite the transformation in volumes and prices, the EU’s net external balance in this sector barely changed, moving from €3 530 M to €3 553 M (+0.6 %). The surplus dipped to a low of €2 523 M in 2020 but rebounded quickly, underscoring the resilience of EU engine manufacturers.
Domestic engine prices surged as the supply mix shifted towards higher-value segments
The rise in overall unit values reflects both genuine price inflation and a compositional shift towards more expensive engine categories, such as aircraft engines (CN 840710) and mid‑range automotive engines (CN 840733). The analysis of product segments (Section 3) details this re‑composition.
2. A New Geography of Trade: Disruption and Diversification Outside the EU
The United Kingdom and Russia collapsed as export markets, while Morocco and Mexico surged
EU export destinations underwent a dramatic reordering. Exports to the United Kingdom fell by 67.6 % (from €917 M to €297 M), and shipments to Russia collapsed by 97.2 % (from €367 M to just €10 M). In sharp contrast, exports to Morocco rocketed 375.9 % (€133 M → €633 M), and Mexico grew an impressive 62.0 % (€536 M → €868 M). The United States remained the dominant partner, holding almost steady at around €2.2 B.
| Export partner | 2015 (€ M) | 2025 (€ M) | Change |
|---|---|---|---|
| United States | 2 236 | 2 198 | –1.7 % |
| Mexico | 536 | 868 | +62.0 % |
| Türkiye | 559 | 687 | +22.8 % |
| Morocco | 133 | 633 | +375.9 % |
| South Africa | 446 | 645 | +44.6 % |
| Russian Federation | 367 | 10 | –97.2 % |
| United Kingdom | 917 | 297 | –67.6 % |

Import sources diversified sharply as China and Türkiye replaced traditional suppliers
On the import side, the EU reduced its reliance on historic suppliers. Imports from the United States dropped 44.2 %, from Mexico 76.1 %, and from Japan 22.2 %, while imports from the United Kingdom declined by 22.5 %. These falls were more than compensated by extraordinary growth from Türkiye (+1 143.2 %, from €29 M to €364 M) and China (+120.2 %, from €149 M to €328 M). The supplier base thus widened considerably.
| Import partner | 2015 (€ M) | 2025 (€ M) | Change |
|---|---|---|---|
| United Kingdom | 1 054 | 817 | –22.5 % |
| China | 149 | 328 | +120.2 % |
| Japan | 506 | 394 | –22.2 % |
| United States | 475 | 265 | –44.2 % |
| Korea, Republic of | 153 | 143 | –6.3 % |
| Mexico | 210 | 50 | –76.1 % |
| Türkiye | 29 | 364 | +1 143.2 % |

Shock events hit key corridors, especially the UK and Moroccan markets
The data reveal several price and supply shocks. A price shock on exports to Morocco in 2022 (+95.2 %) coincided with a 12.9‑abnormality spike, tripling unit values almost overnight. Exports to the United Kingdom likewise experienced a major price shock in 2021 (+57.8 %). On the import side, UK‑sourced engines saw a price shock in 2022 (+18.1 %). The most extreme event was the supply shock in exports to Russia: volumes fell to zero by 2025, a –97.6 % shift compared to the pre‑2022 baseline. The volatility coefficients confirm that flows with the United Kingdom (CV = 0.67 for exports) and Russia (CV = 0.65) were among the most unstable.

3. Structural Transformation: From Bulk Engines to Specialised Powertrains
Large engines (>1 000 cm³) still dominate but lose weight to mid-range and aircraft engines
The product breakdown shows a gradual erosion of the largest engine category (CN 840734, >1 000 cm³) in both imports and exports. While it remains the principal segment, its export value fell from €5 710 M to €4 435 M and its import value from €1 901 M to €1 683 M. The mid‑range engine segment (CN 840733, 250–1 000 cm³) grew dramatically, with exports leaping from €217 M to €1 277 M and imports from €73 M to €251 M. Aircraft engines (CN 840710) also saw a remarkable export value increase, from €46 M to €228 M, driven largely by exceptionally high unit prices (€99 000 in 2015 to €286 000 in 2025).
| Export segment | Description | 2015 value (€ M) | 2025 value (€ M) | Change |
|---|---|---|---|---|
| 840734 | >1 000 cm³ (vehicles) | 5 710 | 4 435 | –22.3 % |
| 840733 | 250–1 000 cm³ (vehicles) | 217 | 1 277 | +488.5 % |
| 840790 | Other engines | 143 | 429 | +201.3 % |
| 840729 | Marine propulsion (excl. outboard) | 89 | 69 | –23.0 % |
| 840721 | Outboard motors | 39 | 32 | –17.3 % |
| 840710 | Aircraft engines | 46 | 228 | +391.4 % |

EU member states show diverging specialisation, with Central Europe gaining ground
The concentration of production capabilities evolved. In 2025, the most specialised exporters were Hungary (RSCA 0.79), Austria (0.60), Poland (0.44), Slovakia (0.28) and Germany (0.15). Germany lost ground as a direct exporter (–30.7 %, from €3 019 M to €2 093 M), while Austria (+100.4 %) and Italy (+330.8 %) expanded their export roles dramatically. On the import side, Slovakia’s intake soared by 286.4 %, reflecting its integration into engine supply chains.
| Top EU exporter | 2015 (€ M) | 2025 (€ M) | Change |
|---|---|---|---|
| Germany | 3 019 | 2 093 | –30.7 % |
| Austria | 799 | 1 602 | +100.4 % |
| Spain | 1 001 | 824 | –17.7 % |
| Italy | 107 | 462 | +330.8 % |
| Romania | 218 | 335 | +53.5 % |
| Hungary | 470 | 253 | –46.1 % |
| France | 207 | 68 | –67.4 % |

Import diversification is reflected in a falling HHI, while export concentration remains stable
The Herfindahl‑Hirschman Index for imports fell from 2 277 to 1 498 (–34.2 %), confirming a much more diversified supplier base. Export concentration remained almost unchanged (HHI from 1 779 to 1 736, –2.4 %), indicating that while the destinations shifted, the overall structure of export sales stayed concentrated on a few large markets.

Conclusion
Over the 2015–2025 period, EU trade in spark‑ignition engines (CN 8407) was characterised by a powerful price upswing that compensated for falling volumes, a profound redrawing of trade routes following Brexit and sanctions against Russia, and a structural pivot towards mid‑range and aircraft engines. The EU preserved its surplus and diversified its import sources, while Central European member states assumed a larger role in production and exports. These dynamics point to a sector that is adapting to geopolitical pressures and evolving global demand for more specialised, higher‑value engine types.
