UK car manufacturing was also given a boost in April as output rose by 5.2% from April 2017 to 127,952 units, putting the brakes on a production downturn that has been in motion all year.
Last month, UK car plants received a 7.3% increase in demand from the domestic market, while overseas demand was up by 4.7%.
In total, 103,662 cars were built for overseas markets in April, meaning exports accounted for 81% of overall demand — that's a 0.4% improvement on the same period last year.
But despite the turnaround in performance from March's 13.3% production decline, the UK’s year-to-date performance remains below that of 2017, falling by 3.9%.
This is largely due to dwindling demand from the home market — which, at 113,650 units is 10.3% down on the same period last year. However, exports are also 2.2% lower year on year at 454,728, representing 80% of overall demand.
UK engine building, on the other hand, reached new heights in April, with 1 million engines produced in the UK across the first four months of the year - an unprecedented feat for Britain's automotive manufacturing industry.
1,013,456 engines left UK factories until the end of April; a 7.5% increase over 2017 equating to 71,128 engines. 61.7% of this 1.01 million were exported, which is an increase in the percentage exported of 15.9%. A particularly buoyant April for engine exports - a 30.5% increase over April 2017 - helped bolster the export figures across the year so far.
Parallel to the stagnation in car manufacturing, engine manufacturing for the home market fell by 3.6% across the year until the end of April compared with the same period last year, equating to 14,554 fewer engines.
