LONDON - British new car sales in 2018 fell at their fastest rate since the global financial crisis a decade ago, hit by a slump in demand for diesel, stricter emissions rules and waning consumer confidence due to Brexit, according to an industry body.
Demand dropped by nearly 7 percent last year to 2.37 million vehicles, the largest fall since registrations nosedived 11.3 percent in 2008, preliminary data from the Society of Motor Manufacturers and Traders (SMMT) showed.
A nearly 30 percent drop in demand for diesel was the most significant factor in the decline. Diesel has been pummelled since the Volkswagen emissions cheating scandal of 2015, prompting a crackdown and higher levies.
But the industry also warned that Britain's departure from the European Union due at the end of March risks the future of a sector which employs over 850,000 people and has been one of Britain's few manufacturing success stories since the 1980s.
"It's still hard to see any upside to Brexit," said SMMT Chief Executive Mike Hawes.
"Everyone recognises that Brexit is an existential threat to the UK automotive industry and we hope a practical solution will prevail," he said, calling for lawmakers to back Prime Minister Theresa May's deal to guarantee a transition period.
Investment looks very likely to have fallen in 2018 and sales this year are forecast to drop again as the SMMT warned a no-deal Brexit would hit jobs.
"You're not going to see immediate closure of plants but what you could see is a reduction in production volumes and certainly, these are often international companies who have alternatives," said Hawes.
After record highs in 2015 and 2016, demand fell in 2017 and some analysts see car demand as a leading indicator which could be a harbinger for future economic performance.
Britain's economy slowed to a crawl at the end of 2018, the housing market is stalling and lending to consumers growing at its slowest pace in nearly four years, according to data released on Friday.
Diesel, which accounted for 48 percent of sales in 2016, fell to 42 percent in 2017 and just 32 percent in 2018, mirroring a trend seen in many European markets.
The rise in petrol sales and drop in diesel means the average CO2 emissions of new cars sold in Britain in 2018 rose just under 3 percent, posing a headache for automakers who need to reduce levels to meet stricter regulations.
New rules which came into force in September also impacted sales by disrupting the supply of some models, the SMMT said.
Demand this year could also be distorted if Britons fear tariffs could be introduced after Brexit perhaps pushing up registrations in the first three months of 2019.
The complete figures for 2018, which include the final few registrations submitted by paper rather than electronically, will be released at 0900 GMT.
