Not only would a diesel version of these cars bring forward a more fuel efficient and eco-friendly Porsche product to US shores, a hybrid version of each could also be on the way. Reports say Porsche is about to unveil an all-new hybrid range at the upcoming Geneva Motor Show in March.

These hybrids are then likely to become available in the US market soon after. Americans are very keen on 'green' cars, with Porsche already being a popular product, introducing eco versions of these cars could do wonders for the German sports car maker.

Porsche sales and marketing chief, Bernhard Maier, recently told Automotive News Europe,

"We are discussing internally if we should introduce the Cayenne diesel in the US this year. Also a Panamera diesel is an option."

Even though the Porsche Cayenne diesel has been around since 2009 in other markets (including Australia), the US market is very interested in eco cars, such as hybrids, but diesels are yet to take up a decent segment of the market.

Porsche says up to 30 percent of Porsche Cayenne sales internationally are made up of diesel variants. The company expects this figure to be significantly higher by the end of 2011.

Bernhard Maier says the company will make the decision about the introduction of the cars into the US very soon.
