Porsche is taking the all-electric game straight to the Tesla Model S with its upcoming model, the Mission E, which was last seen pounding the miles at the famed Nurburgring Nordscleife circuit. It has been sighted on a few occasions since its first public showing as a concept at the 2015 Frankfurt Motor Show, and is now undergoing cold-weather testing.

Much of the Mission E’s exterior here appears identical to that at its last sighting, complete with what appears to be non-functional, cosmetic ‘tailpipes’. To recap, the Mission E Concept is said to produce 600 hp in concept form courtesy of two permanent magnet synchronous motors fed by a lithium-ion battery pack located between the two axles.

The Mission E will have a cruising range of 500 km, according to Porsche, and a 15-minute charge from a 800 V, 350 kW liquid-cooled charging station gives a battery range of 400 km. Performance won’t be lacking; 0-100 km/h is done in a claimed 3.5 seconds and 200 km/h in 12 seconds, along with a Nurburgring lap time of under eight minutes around the fabled North Loop.

When it comes to market, the Mission E will be made available for sale in numerous variants similar to current Porsche model strategy, Porsche boss Oliver Blume told Car Magazine, similar to the base, S and GTS versions of the 911 and 718 Boxster/Cayman. When it goes on sale, the Porsche Mission E can be expected to be priced from a similar starting point as the Panamera‘s.
