Diesel registrations fell -30.6% in the month and are now tracking at -16.1% in the year-to-date. Sales to fleet owners of more than 25 company cars or cars for rent fell by 14.4 per cent.
Figures released today by the Society of Motor Manufacturers and Traders (SMMT) showed that demand for new cars fell in November, with 11.2 percent fewer cars sold than in the same month a year ago. November's expected drop in sales would add to the fall of almost 5 percent in overall registrations between January and October.
Sales figures for November showed a general decline in new vehicle registrations, with the 163,541 cars sold being 11% down on the same period past year.
This is the eigth consecutive month of decline in United Kingdom vehicle sales, something which the Society of Motor Manufacturers and Traders has branded as a "major concern". "The decision to tax the latest low-emission diesels is a step backwards and will only discourage drivers from trading in their older, more polluting cars".
Hawes explained that the decrease in fleet registrations will have a marked impact on the UK's air quality improvements, with "detrimental environmental and economic consequences" if the market continues to shift away from the newest, cleanest diesels.
At issue is the slump in the sale of diesel engines cars, down 30.6 per cent last month.
When it comes to the cars themselves, it appears the Ford Fiesta is flavour of the month, after missing out on the best-seller spot for a few months.
SMMT chief executive Mike Hawes commented: "An eighth month of decline in the new auto market is a major concern, with falling business and consumer confidence exacerbated by ongoing anti-diesel messages from government".
"Anyone holding out for a confidence boost from the Budget will have been sorely disappointed, as the Chancellor's statement only served to further exacerbate the problem".
He added that consumers needed clarity over what charges or other restrictions might be placed on diesel vehicles in future to help them make informed car-buying decisions.
