Germany luxury carmaker Porsche is studying whether to build a hybrid version of its Cayenne sport utility vehicle using a Toyota Motor powertrain, Automobilwoche reported on Monday.

A Porsche spokesman confirmed to Reuters it was studying a hybrid version of the Cayenne but would not give more details.

Should current feasibility studies work out, Porsche would adopt the 270 horsepower petrol-electric powertrain to be used in the Lexus RX 400h SUV, Automobilwoche reportedly said, citing a Porsche source. The RX 400h, based on the Lexus RX 330, is set to go on sale in the United States in December.

Reuters noted that hybrid technology could help Porsche meet tougher environmental standards in Europe and the United States, where rule changes are beginning to take effect. Stricter US emissions regulations will be phased in by the end of 2009. The United States is Porsche’s primary sales market.
