The Mission E concept car is capable of 0-60mph in under 3.5 seconds - still short against its rival the Tesla Model S, which claims a 0-60mph in 2.8 seconds.
Porsche has said it could be its first all-electrically powered four-seat sports car.
Parent company Volkswagen said it will be available to buy by early 2018.
Porsche, which revealed the car at the Frankfurt Motor Show, is a little bit behind the curve given that the prototype of the Model S was launched at the same event six years ago.
However, potential customers may be impressed by the charging speed - Porsche says the Mission E will reach 80% charge in around 15 minutes.
They also say it could travel more than 300 miles on one battery charge.
According to Porsche, the Mission E will also share your mood with others while driving - a camera mounted in the rear-view mirror recognises when the driver is happy and displays an emoticon.
This can be saved by the car's computer with information such as the route or speed before being shared with friends on social media.
Price details have not been revealed, but it has been suggested the cost could start at £100,000.
Car makers are coming under increasing pressure from Brussels not just to limit carbon emissions but also address the health problems linked to diesel fumes.
