According to a story we read, Porsche's production lines for all models destined for the UK and Europe will temporarily close in order to retool in preparation for new Worldwide Harmonized Light Vehicle Test Procedure emissions and fuel economy test standards set to come into effect in September. The UN Economic Commission for Europe determined that the existing NEDC testing standards are clearly not capable of capturing real-world examples, and as such have extended the testing procedure to incorporate a more accurate representative result. Porsche, as a result of the new testing schedule, will be updating and retesting each model to be in compliance with this standard. A Porsche spokesman told Autocar that the company has been gradually growing their global stock of cars to reduce any backlog of demand for new car sales. Because the production lines will be shut down, and buyers will be buying cars that have potentially been sitting on lots for a few months, new car orders are limited to existing models.
