SMMT: Car production stabilises but outlook still challenging

• UK vehicle production falls -8.2% in March, with 72,511 units leaving factories.
• Car output steady, down just -0.8%, while CV volumes drop -68.3%.
• Car production for domestic market grows, as exports decline despite EU demand rising.
• Sector calls for urgent amendment to EU Industrial Accelerator Act to include the UK as a trusted trading partner. 

UK vehicle production fell -8.2% in March, with 72,511 units rolling out of factories, according to the latest figures published today by the Society of Motor Manufacturers and Traders (SMMT). 69,755 cars (down -0.8%) and 2,756 commercial vehicles (down -68.3%) were produced following strong growth last year.¹ Car output was also affected by a part supply challenge temporarily pausing production at a large plant, weak exports to Asian and US markets, and model changeovers. CV volumes continued to reflect a major manufacturer restructuring in 2025.

Exports of cars and CVs both fell, down -4.3% and -54.0%, to 49,339 and 1,602 units respectively. Despite this, production for overseas buyers still accounted for the majority (70.3%) of vehicle output. The EU remained the UK's largest global market, taking 91.6% (1,467 units) of CV exports and 62.6% (30,899 units) of car exports. 

EU demand for UK-built cars, rose for a fourth consecutive month,² with exports up 4.8% year on year. That growth, however, was offset by a decline in production for the US (-24.1%), China (-47.9%) and Japan (-25.3%), which together accounted for 18.6% of all shipments. Car output for British buyers, meanwhile, rose 8.7%, while CV production for the UK fell -77.9%. 

In the first quarter, UK factories produced 208,088 vehicles, down -13.0% on the same period in 2025. Car output fell -6.7% to 200,889 units, while CV volumes declined -70.0% to 7,199 units, again due primarily to last year's closure of one of the UK's larger plants. Output for overseas markets represented 75.8% of all vehicles made, although exports fell -12.4%, with production for the UK down -14.8%.

With the UK's manufacturing competitiveness under intense pressure, the announcement earlier this month of the final design of the British Industry Competitiveness Scheme (BICS) represents a major win for Britain's automotive manufacturers. It promises to drive down the sector's electricity costs – among the highest in the world – to support more favourable competition with plants abroad.³  

This is vital as the global environment is particularly challenging for the sector. Energy price volatility from the ongoing conflict in the Middle East is likely to raise costs in the short to medium term, and the impact of oil price rises could also dampen demand in key markets. Furthermore, the sector faces the prospect of being severely disadvantaged by the EU's proposed Industrial Accelerator Act and ‘Made in Europe' policy which, as currently drafted could exclude UK automotive products from substantial segments of the European market undermining the competitive position of UK plants. 

Given the vital interdependence of EU-UK automotive trade, worth an annual €80 billion and with the balance firmly in favour of the EU, SMMT is calling for urgent amendments to the policy to ensure the UK automotive sector continues to be treated as a trusted partner. Granting UK-built vehicles, parts and batteries equivalent treatment across all relevant provisions would protect a long-established, mutually beneficial trading relationship that supports jobs, supply chain resilience, industrial transformation and decarbonisation, and ensures consumer choice and affordability.

Manufacturers on both sides also face the prospect of tariffs on electrified vehicles and batteries with the introduction of tougher rules of origin in 2027 as part of the Trade Cooperation Agreement (the “Brexit deal”). As a result, industry is urging governments to look at pragmatic solutions and use the forthcoming EU-UK summit to include discussion of automotive issues so that the trading relationship can be improved to mutual benefit.  

Mike Hawes, SMMT Chief Executive, said, “Car production stabilising in March is welcome news for both assembly and the wider supply chain. Government's recent intervention to bring down electricity costs will provide a major and long-called for boost, but the scheme's benefits must be delivered urgently as the geopolitical situation offers little optimism. We must ensure any ‘Made in Europe' proposals from the European Commission do not exclude the UK as the two industries are integrated such that both would suffer if the free trade provisions enshrined in the Brexit deal were undermined. The EU and UK must work together to avoid that scenario – and the looming threat of tariffs arising from stricter rules of origin on electrified vehicles – to ensure a positive outcome for industry, economies and consumers on both sides of the Channel.”
