Germany's Porsche AG said it will cut prices for its sports cars in Britain from May 1 because of the strength of sterling. The Stuttgart-based company said the price cuts would range from 7.2 percent for the 911 Carrera 2 Coupe models and 9.6 percent for the Boxster S. Porsche expects the price cuts to boost sales in Britain of the Boxster and 911 models in its coming business year, starting August 1.
