Porsche is no stranger to electrification, but the German automaker has yet to add a fully electric car to its line-up. That will change in the not-too-distant future, as the Mission E could pose a serious threat to Tesla when it enters production in 2019. So far, the Mission E has only been shown in concept form, and now Porsche has unveiled another fully electric car concept based on the Cayman. Dubbed the Porsche Cayman E-Volution Prototype, the fully electric sports car was presented at the Electric Vehicle Symposium in Stuttgart, Germany.

Porsche says the electrified Cayman isn't previewing a future production car, but it does hint at the potential performance we can expect from future Porsche EVs. No details have been shared about the powertrain, but Porsche claims that the Cayman E-Volution Prototype can hit 0-62 mph in a mere 3.3 seconds, making it faster than any current Cayman. For comparison, the Porsche 718 Cayman S needs 4.2 seconds to reach the same speed. Less impressive is the range. On a full charge, the Porsche Cayman E-Volution will last a paltry 124 miles, but it's only a research vehicle to be fair. Its styling appears to be based on the old 981 Cayman, rather than the current 718 model.

The fully electric Cayman concept is primarily designed to preview the Mission E's 800-volt Turbo Charging system, which will recharge the battery pack from 0 to 80 percent in 15 minutes. When it arrives in 2019, Porsche's first fully electric car, the Mission E, will have a range of 310 miles to rival the Tesla Model S and Model 3. The automaker's first ever accumulator-based fast charging system was developed in collaboration with ADS-TEC and is capable of achieving a charging capacity of up to 320 kW per vehicle or twice 160 kW. It's ideal for areas where the power limitations are affecting the distribution system.

Porsche says it will be used as a supplement to a high-power fast charging network with a medium voltage connection. One of these networks will be built on major European traffic routes by 2020 in a joint venture between Porsche, Audi, BMW, Daimler and Ford.
