London Mayor Boris Johnson has announced plans to radically shake up the capital's Congestion Charge.
All cars that emit less than 100g/km of CO2 and meet the other Euro V emissions standards will get a 100% exemption from the charge.
The plan is that hybrids and other alternative-fuel vehicles will be given exemption only if they meet these standards, so hybrids with higher CO2 output, such as the Lexus 450h, will miss out.
All fully electric and plug-in hybrid vehicles that are able to run under battery power alone will also be given a 100% exemption under the proposals, which are under consultation until August 2, and will be put in place by the end of this year.
Here's a full run down of the cars that will gain the exemption under the plans, and those that will lose it.
