Currently reading: August UK diesel car registrations slump ahead of '67' plate switchover
August is typically a quieter month due to the change, but last month’s registrations were the lowest in three years

August’s new car registrations were the lowest since 2014, marking an unusually low pre-reg change month compared with the past two years. 

Registrations in August had been increasing annually since 2010, but last month's registrations shrunk by 6.4% on 2016, which was the strongest year since 2005. 

Driving the slump was the UK public’s shunning of diesels; in excess of 8000 fewer diesel cars were registered in August 2017 compared with August 2016; a 21.3% decrease. Petrol cars remained buoyant, however, with a 3.8% increase. 

The tide turning on diesel is even more apparent when comparing market shares. In August 2016, the market was split into 47.2% diesel, 49.7% petrol and 3.1% alternative-fuelled vehicle (hybrid, hydrogen or electric). In August 2017, diesel fell to 39.6%, while petrol and alternative-fuelled vehicle registrations grew to a 55.2% and 5.2% share respectively.

Private, fleet and business buyers all showed decreases. The private market posted the biggest fall, declining almost 10% as 3672 fewer cars were registered by private buyers. Fleet registrations decreased by 3.2%, while business registrations fell by 14.1%, although this only equates to 154 cars. 

Across the year so far, a softer 2.4% decline has been recorded, equating to over 40,000 fewer cars registered. A total of 1.64 million cars were registered in the year to date. 

Society of Motor Manufacturers and Traders chief Mike Hawes played down the relatively low figures and predicted a more promising October, saying: “August is typically a quiet month for the new car market as consumers and businesses delay purchases until the arrival of the new number plate in September.

“With the new '67' plate now available and a range of new models in showrooms, we anticipate the continuation of what are historically high levels of demand.”

The top 10 most-registered cars in August was a more budget-friendly list, with no premium offerings in the rankings. Cars that are not usually seen in the list, such as the Kia Sportage, Ford Kuga and Vauxhall Mokka X, took the place of more expensive cars such as the Mercedes-Benz C-Class, Mini and Mercedes-Benz A-Class, although these all maintained their respective eighth, ninth and tenth positions in the year-to-date rankings.

1. Ford Fiesta - 64,988

2. Ford Focus - 47,291

3. Volkswagen Golf - 44,218

4. Nissan Qashqai - 39,698

Seat's third-generation Leon is attractive and capable, but it can't quite reach the benchmark set by the imperious Volkswagen Golf

Not low enough

These figures need to fall a hell of a long way yet.  It is stupid that in a world of cars with greater reliability there is more and more push for replacing them with new cars sooner and sooner.  The real future is to enhance the longevity of cars and to keep them running for longer and longer.  That is the only truly environmentally friendly option for the future of motoring.

So given the big boon in crossover SUV sales

There is only 1 on the list. Small hatchbacks abound. Except the C class which is heavily discounted on a PCP so is a bit of an anomoly

The C class is really bucking the trend as the D segment saloon market is deflated in favour of crossovers (we lost the Honda Accord etc.)

From Sept 2017, tougher regs will cut pollution, even under real world, and not just lab conditions.

Diesel engines are more fuel efficient. So a fall in sales will reduce EUs chances of meeting its target of cutting average CO2 emissions of new cars from 130 in 2015 to 95 g/km in 2021.

And therein lies the dilemma.  Without diesel, EU will not be able to comply with this limit.

I think you'll find 8 out 10 cars in the list have models below 100 g/km already so 2021 won't be a problem for the majority. And that's before allowing for the influx of EV's in the next 4 years.
