Motorists buying the most polluting cars will today be hit with a £950 top rate of road tax.
The owners of more than six million vehicles already on the road also face tax rises of more than twice the rate of inflation.
The Vehicle Excise Duty rates, which were first announced in 2008 but come into force today, are designed to reflect car engine emissions.
Some 13 emission bands are in place, with the owners of the highest polluting vehicles paying the most road tax.
An additional one-off showroom tax will also apply to anyone buying a car in the most polluting bands. Nine of the 13 categories will have to pay this tax.
