UK vehicle production fell nearly 16% last year, the Society of Motor Manufacturers and Traders (SMMT) said, marking what the trade body called the toughest annual performance for British vehicle manufacturing in a generation.

The headline figure, reported by Reuters, covers UK passenger car and commercial vehicle output tracked across the SMMT's manufacturing membership. The 16% annual decline exceeds the post-financial-crisis reset of 2009 and stands as the weakest calendar-year result in modern SMMT records.

How steep is the 16% drop?

A contraction of this magnitude inverts more than a decade of post-pandemic recovery trends. The figure represents one of the largest single-year declines the trade body has measured in its monthly and annual production tracking.

The decline touches every major UK assembly footprint:

• Nissan plants in Sunderland
• Jaguar Land Rover operations at Solihull, Castle Bromwich and Halewood
• BMW's Mini factories at Oxford and Swindon
• Stellantis's Ellesmere Port and Luton sites
• DAF and other commercial-vehicle lines

The SMMT does not break out the headline loss by individual OEM.

What is driving the contraction?

The SMMT has linked the slump to three overlapping pressures:

• Weak demand in core export markets, particularly the EU, where EV adoption has slowed and fleet renewal remains depressed
• Model changeover timing, with several UK plants mid-transition to new platforms during the year
• Structural cost pressure from energy prices, labour costs, and post-Brexit trading arrangements that reintroduce tariffs and customs friction to UK-EU vehicle and component flows

The combined effect is a manufacturing year defined by fewer working days, slower order intake, and rising per-unit costs that erode the competitiveness of UK-built vehicles against alternatives from continental European plants. The SMMT has repeatedly called for a UK-EU deal that would restore zero-tariff conditions for EVs and components — a position the trade body argues is essential to plant-level competitiveness.

What is confirmed, what is still claimed

The 16% annual figure is confirmed SMMT output data based on plant-reported volumes. Recovery narratives tied to new UK programmes — the all-electric Mini at Oxford, the relaunch of Jaguar at Solihull, electric vans at Ellesmere Port, and the next-generation Nissan crossover programme at Sunderland — remain launch-schedule claims rather than verified production data. The SMMT does not publish a forward-looking production forecast alongside the annual release.

How does this fit the longer UK manufacturing picture?

The latest decline compounds a multi-year compression of British vehicle output. Several legacy programmes have wound down since the start of the decade, and OEMs have publicly flagged the cost competitiveness of UK plants versus lower-cost alternatives in Spain, France and central Europe. New-model mandates must clear a higher bar than at any point since the 1980s, and plant investment decisions are increasingly tied to policy support on trade arrangements.

What to watch next

• The next monthly SMMT production release, which will indicate whether the steep 16% annual decline continues into the current year or shows early signs of flattening.
• The UK government's negotiation stance with the EU on rules of origin and EV tariffs, which the SMMT has flagged as the single largest variable in restoring plant competitiveness.
• The launch and ramp timing of the all-electric Mini at Oxford, the relaunched Jaguar line-up at Solihull, and the next-generation Nissan crossover programme at Sunderland — three UK programmes whose output curves will set the volume trajectory for the rest of the year.
