Tesla Motors announced plans to expand its European Supercharger network and showrooms during the Frankfurt Auto Show.

The next six markets to get Supercharger stations include: Germany, Belgium, Denmark, Iceland, Luxembourg, the Netherlands, Spain and Switzerland.

Supercharger stations can be used, for free, to charge Model S vehicles.

"This year has already been one of tremendous growth and expansion throughout Europe for Tesla and Model S," said CEO Elon Musk in a press statement.

Telsa has set a goal to sell 21,000 Model S vehicles worldwide in 2013.

Musk said the automaker is hoping to compete with companies like BMW and Mercedes-Benz in Europe.

In the U.S., Tesla opened its 26th Supercharger station in Waco, Texas and will open more stations throughout the Northeast by October.

Tesla has a plan in place to have 100 Supercharger stations open in the U.S. and Canada by 2015.

Supercharger stations can only be used by Model S vehicles and won't work with other plug-in vehicles.

Last week Musk revealed he was taking a six-day family trip in his Model S from California to New York. He claims that the trip will only require nine-hours of charging total.
