Diesel car sales fall but new tech could make it cleaner and greener

Diesel cars are blamed for poor air quality courtesy of their exhaust emissions

Diesel car sales are falling as drivers turn their back on it because of health concerns. But diesel power is about to hit back with new technology designed to reduce harmful exhaust emissions.

Official figures show that sales of diesel cars were down in the UK by a fifth in May 2017 and by 15 per cent in June. That’s compared with the same period in the previous year. The slump is believed to have been caused by various factors. The high-profile Volkswagen diesel cheat device case raised people’s awareness of the harm of the nitrogen oxide (NOx) pollutants diesel produces. But people are also concerned that diesel cars may be slapped with hefty taxes.

However, we can reveal that diesel is hitting back. Automotive technology giant Continental has worked out how to make a much cleaner diesel car.

Why do we need diesel?

Drivers travelling to France require an emissions sticker to enter Paris, Lyon or Grenoble

Drivers travelling to France require an emissions sticker to enter Paris, Lyon or Grenoble

Air pollution means cars with high emissions could be prevented from entering Paris or Lyon

As millions of Britons make plans for their Easter or summer holidays, travellers driving to France must ensure that their car has an emissions sticker when visiting Paris or Lyon – the two largest cities in France.

The sticker system has been introduced to help tackle air pollution in city environments, and is active in Grenoble, as well. Other French cities are likely to join the scheme.

Called Crit’Air, it effectively bans old cars from city centres during weekdays and will allow authorities to restrict which cars are permitted to enter cities.

Choosing the best car: top 10 diesel and petrol cars with the lowest nitrogen oxide emissions

Nitrogen oxide emissions

It’s not easy being a driver who wants to do their bit and buy a car with the lowest nitrogen oxide emissions. These NOx are harmful pollutants emitted by cars that are estimated to contribute to over 30,000 premature deaths a year in the UK. Information about a car’s NOx levels has been hard to come by as, for obvious reasons, vehicle manufacturers tend to advertise cars’ fuel economy or performance rather than the nasty particulates pumped out of exhausts.

But now a new website allows drivers to see just how polluting Britain’s most popular makes and model of car are when used in normal, everyday driving conditions.

Emissions shock: 95% of cars are illegal. What does it mean for drivers?

Emissions shock

New research says nearly every car pumps out illegal levels of toxic gases

It’s not just Volkswagens that allegedly pump dangerous toxins into the atmosphere, according to the latest emissions shock. New research claims nine out of 10 diesel cars on Britain’s roads exceed official limits for illegal gases. The study also found that 10 per cent of petrol cars surpassed nitrogen oxide (NOx) limits, set in 2011. And the majority of petrol cars go beyond EU carbon monoxide (CO) output levels.

According to Which?, part of the Consumer Association: “It’s not just Volkswagen. In fact, it’s not just diesel engines, either. It’s almost everyone. Whether diesel, petrol or hybrid, the majority of cars exceed EU emission limits when faced with our more realistic tests.” So what is the truth behind the latest revelations? And more importantly where, as drivers and car owners, do we stand? Continue reading

Volkswagen emissions scandal: What it really means for British VW owners

VW emissions scandal

The Volkswagen emissions scandal has rocked the car industry and prompted drivers everywhere to wonder if they can trust anything car makers tell them. The outrage was discovered in the US and involves a programme hidden in cars’ computers. This can tell when the vehicle is undergoing an emissions test. It then switches the engine to a mode where it emits less Nitrogen Oxide (NOx) to pass strict air quality tests. There are 11 million cars world-wide that could be affected. Here’s what British drivers need to know.
