Diesel cars: Your questions answered - which is the best electric toothbrush to buy

According to a new study, diesel car sales will decline this year, accounting for only 15% of the UK market by 2025, below the peak of 50%.
Professor David Bailey of Aston University, an automotive expert, said the "slow death" of diesel was driven by "environmental pressure and consumer confusion.
We ask you to send your questions about the diesel industry to our business correspondent Theo Leggate.
Diesel is more fuel in general
More efficient than gasoline models, and produce less carbon dioxide
One of the major gases associated with climate change.
Gordon Brown, the Chancellor, has introduced tax incentives to encourage people to buy.
However, in recent years, more attention has been paid to urban air quality, and it is clear that other emissions of diesel engines, especially nitrogen oxides or NOx, are an important cause of urban pollution.
The Volkswagen scandal two years ago highlighted the higher levels of NOx that many cars produce when they are used on the road, which have passed official laboratory tests.
This has triggered the political backlash we are seeing today.
The rebound seems to be affecting the second one.
The market and demand for new cars.
Data from Motorway, a car sales website. co.
For example, the UK says the average of diesel oil used for three years has declined over the past year, while the average of gasoline models has risen.
Now, you might think that the old diesel models will lose value in the current climate because they are dirtier and therefore more susceptible to restrictions such as access to the city center.
The reason for the recent car depreciation faster may be related to the general lack of enthusiasm for diesel and new and close-
As dealers find it harder to move new models from their forecasts, new models will fall.
If the price of the latest car is greatly discounted at the beginning, then resale and partial discount
Of course, the exchange value may also drop. What Car?
If you put millions of electric cars on the road today, the biggest diesel discount store won't have enough public charging points.
Two things, however, are worth remembering.
First, automakers are working to improve the driving range of the new electric vehicle model.
If the range of more than 300 miles becomes the norm, many car owners rarely need to charge their cars where they are away from home.
After all, the average mileage of a car is less than nine miles.
Of course, they also need a place to charge overnight.
At home or on the street.
Secondly, although the number of electric vehicles on the road is still very small, the number of charging points is rapidly increasing, and this trend may accelerate as enterprises see development opportunities.
The manufacturer decided to sell the electric model, so the incentive was there.
If you buy a new diesel you will have to pay the car excise duty.
Only cars with zero emissions are tax-free.
The system was transformed in April, a bit complicated, but basically the owner of all new cars --except zero-
Emission model
Fixed annual interest rates for the pound will be paid.
In addition to this, there are additional payments based on carbon dioxide emissions, and luxury car owners pay more.
In the budget for November, the government announced all diesel that did not meet the latest actual situation
World emission standards
Will actually come into effect on 2020-
There will be higher charges.
The car tax for diesel companies has also increased.
Car owners are not affected.
The old tax regime based on carbon dioxide emissions will continue to apply to them.
The system was originally built to encourage cars that emit low-level carbon dioxide.
Including diesel
Because the political focus at the time was to deal with climate change, not clean urban air. Good question.
What industry insiders call "-
"Diesel speech" from the government ".
They want authoritative sources to make it clear that the latest diesel is cleaner than the old model and has a cost advantage for drivers with more mileage due to lower fuel consumption, will not be affected by restrictions on access to towns.
However, the government itself seems to focus more on promoting zero.
Emission vehicles-
And its long term statement
The semester goal is to eliminate vehicles using internal combustion engines by 2040.
If diesel is to survive, the industry needs to convince ministers that diesel can still play an important role in helping achieve climate change goals.
