Car tax rules for a 2018 car

Cars first registered from 1 April 2017 pay a first-year rate set by CO2 emissions, then the standard rate each year. A petrol, diesel or hybrid car with a list price over £40,000 also pays the expensive car supplement for five years, from the second tax payment.

These are the rules, not the amount for a specific car. Car tax check

ULEZ and clean air zones

Petrol cars first registered from 2006 usually meet Euro 4, the petrol standard for the London ULEZ, so they usually do not pay the daily charge.
Diesel cars first registered from September 2015 usually meet Euro 6, the diesel standard for the London ULEZ, so they usually do not pay the daily charge.
The clean air zones in Birmingham and Bristol use the same Euro 4 petrol and Euro 6 diesel standards. The low emission zones in Scotland use them too, but enforce them with fines, not a daily charge.

The Euro standard of the car decides, not the year alone. ULEZ checker

More on the Audi Q5

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.
