BERLIN -- German voters who propelled the Green Party to a record result in Baden-Wuerttemberg may have ushered in a speed limit on highways in the state that's home to luxury carmakers Porsche AG and Daimler AG's Mercedes-Benz unit.
The Greens helped defeat Chancellor Angela Merkel's coalition in a regional election yesterday on a platform that includes a speed limit of 120kph (74.6 mph) to help reduce vehicle emissions. That speed limit is less than half the top speed of a recent Porsche model.
About 65 percent of the state's highways currently have no speed limit.
"Traffic in Baden-Wuerttemberg contributes about 30 percent to CO2 emissions," Winfried Kretschmann, who is poised to become the Greens' first state premier, said on the party's Web site. "It's clear that the transportation sector has to make a contribution of its own to reduce this gas that's harmful to the environment."
An Autobahn speed limit is just one measure that may affect the car industry in the state where the first gasoline-powered automobile was patented in 1886 by Carl Benz.
The Greens also favor "more efficient engines," the development of cars that use less gasoline, the introduction of city tolls and tax breaks for environmentally friendly vehicles.
Stuttgart-based Porsche, which was this month due to begin selling a 63,400 euro ($89,300) Boxster S Black Edition with a top speed of 276 kph, declined to comment on the outcome of Sunday's elections, spokesman Dirk Erat said by phone Monday.
