Overseas demand showed the biggest gains, up 14.3% in the month, while production for the home market was broadly stable, falling slightly by -1.4%. It was a trend reflected in first quarter figures, with exports for the first three months growing 11.1% to 329,653 units, while domestic output also rose by 8%, buoyed by stronger growth in January and February, to take overall manufacturing volumes to 443,581, an increase of 10.3%.
The news comes as the latest productivity figures released for 2015 show that each employee in automotive manufacturing generated on average £79,700 per car produced, up 1.3% on 2014.
Mike Hawes, SMMT chief executive, said, “UK car plants were at their busiest for 12 years in March, with a vehicle rolling off production lines every 16 seconds thanks to heightened international demand for British-built cars. Much will depend on economic and political conditions in key markets but, with several brand new global models starting production here in the first quarter alone, the prospects for future growth look bright.”
