The German carmaker believes that the increase of the congestion charge from £8 a day, or £0.80 for residents, to £25 is both unfair and disproportionate and argues that the charge will increase congestion and damage air quality in London.
Commenting on the filing, Andy Goss, Managing Director of Porsche Cars GB, said: 'Not only is this new tax on motorists unfair, it is also a disproportionate and illegal use of power by the mayor.
'The Porsche case is about protecting London and Londoners from a new tax that will not only fail to reduce CO2 emissions in central London, but also increase congestion and damage air quality.'
Porsche filed its challenge in the High Court of Justice Queen’s Bench Division Administrative Court seeking to quash the mayor’s new charge on the grounds that it is both a disproportionate and illegal action by the Mayor.
Because of the short time frame in which the charge is due to be introduced Porsche has asked the court to expedite the judicial proceedings.
