Porsche believes that the increase of the congestion charge from £8 a day to £25 is "unfair and disproportionate" and could result in an 11% drop in sales in the UK.
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."
Pendragon Premium, which has three dealerships in central London, has filed a seperate claim, stating that it could face up to £180,000 in higher congestion charge costs.
Porsche started its campaign against the changes to the congestion charge in February. The Friends of the Earth has hit out against Porsche’s challenge over the new CC rules, saying the luxury car marque "has a vested interest in keeping polluting vehicles on the road".
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".
