Porsche's All-Electric Tesla Competitor Coming To Frankfurt As Concept: Report

Among established luxury brands, Porsche may be among the best equipped to challenge Tesla Motors.

The German automaker known for its sports cars has already built three plug-in hybrids, beating Audi, BMW, and Mercedes-Benz to launch that powertrain in the large luxury sedan and mid-size crossover segments.

And there have been persistent rumors that it will follow those up with an all-electric sedan of some kind.

The latest is a report from French car magazine L'Automobile saying that an electric Porsche concept car will appear at the 2015 Frankfurt Motor Show in September.

This concept is expected to preview the "Pajun"--Porsche's rumored mid-size luxury sedan.

That code name is short for "Panamera Junior," denoting the new model's slot below Porsche's existing full-size sedan in the lineup.

The Pajun--which is likely to be offered with internal-combustion powertrains as well--will likely compete with models like the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class.

That means it should be close in size to the Tesla Model S as well.

While Porsche hasn't yet shown any all-electric cars in public, there's been plenty of speculation about its plans for them.
