* Applies to vehicles not meeting real-world Euro 6 standards.
What cars will be hit by the April 2018 changes?
The changes impact first-year tax rates for new diesel vehicles not meeting real-world Euro 6 standards.
This means that new cars can emit up to 1.5 times the current 80mg/km NOx limit under real-world driving tests to avoid being bumped up a tax band.
The changes will apply to new vehicles first-registered from April 1, 2018. Older cars will not be hit by the hikes.
Does this apply to vans?
No – the increase in charges is reserved for cars.
Why have the rates changed – again?
These changes in rates can be seen as a realignment ahead of bigger changes coming into force from September 2019, when methods used to measure emissions will change.
New emissions testing will swap from the laboratory to real-world driving situations. This is expected reveal a significant increase in emissions levels for most cars – meaning bigger bills for many drivers.
So, give some examples of cars that will now cost more to tax – and by how much!

According to AutoExpress, cars such as the Ford Fiesta are likely to owe £20 more under new first-year tax rates, but higher-polluting motors, like the Porsche Cayenne, are expected to be hit by hikes of up to £500.
So it’s only new-car drivers that’ll pay more?
No. Anyone who bought a car just before April last year could be hit by an increase in the standard rate tax payment.
The new standard charge will be £140 – and £450 per year for vehicles costing over £40,000.
