Porsche Cayman e-volution Electric Concept Charges At 800 Volts, 0 To 62 MPH In 3.3 Seconds


In case you were having doubts, the future is electric.

Almost a week after catching a first glimpse of the Mission E in the wild testing, today we bring news about another fully electric car from Porsche. Only a concept at this point, but the Cayman-based e-volution serves as a research vehicle and is currently on display in Germany at the Electric Vehicle Symposium in Stuttgart. While it may look like a fairly standard pre-facelift Cayman (981) with some green accents inherited from the 918 Spyder, it’s actually significantly different underneath the familiar skin.

With this being a fully electric vehicle, it goes without saying the “Turbo Charging” lettering on the doors does not refer to the powertrain’s forced induction. It’s there to denote the concept’s charging voltage of 800 volts and serves as preview for the Mission E’s Porsche Turbo Charging system capable of recharging the battery pack to an 80 percent level in just 15 minutes.

Porsche is making it crystal clear the Cayman e-volution is not destined for production as it’s only a stepping stone for EV development. The future is exciting if we take into account the all-electric coupe is seriously quick by reaching 62 mph (100 kph) in only 3.3 seconds or 1.3s less than today’s 718 Cayman in the hot S specification.

With a full charge, the unspecified battery pack can last for up to 124 miles (200 kilometers), which isn’t very impressive, but bear in mind this is merely a research vehicle. As a reminder, the aforementioned Mission E due in 2019 will do ~311 miles (500 km) between charges (NEDC – 250 miles/400 km in likely real-world/EPA-estimated range).

For the first time, the sports car marque is showcasing at the Electric Vehicle Symposium an accumulator-based fast-charging system developed by Porsche Engineering in collaboration with ADS-TEC. Tailored to areas where power limitations are affecting the distribution system, this version of the Porsche Turbo Charging system can achieve a maximum charging capacity of 320 kW for a single electric car or twice 160 kW.

Porsche has made the promise it will be put to good use as a supplement to a high-power fast-charging network with medium voltage connection and one of these networks will be operational by 2020 on important traffic routes in Europe. To make it happen, Porsche has joined forces not only with Audi part of the same VW Group, but also with BMW, Daimler, and Ford.

Press blast below:

E-Performance at the Electric Vehicle Symposium

Industry gathering on the topic of e-mobility: As part of the Electric Vehicle Symposium (EVS) at the Messe Stuttgart exhibition site, Porsche AG is showcasing the future of the sports car.

With the Cayman e-volution the company presents a research vehicle with a charging voltage of 800 volts that accelerates from zero to 100 km/h in 3.3 seconds and offers a range of 200 kilometres. The vehicle will not go into series production, but does give an early indication of just how sporty Porsche believes e-mobility can be. It is also a hint of what is to come in 2019, when Porsche will bring its first purely electric sports car, the Mission E, into production. The Mission E will be capable of covering a range of over 500 kilometres, and will be able to charge its batteries to 80 per cent within just 15 minutes.

With Porsche Turbo Charging, the sports car manufacturer is also showcasing its first ever accumulator-based fast charging system, which is capable of achieving a charging capacity of up to 320 kW per vehicle or twice 160 kW. The system is a collaborative development between Porsche Engineering and ADS-TEC, and is particularly suitable for use in areas where the distribution system is subject to power limitations. The system is to be used as a supplement to high-power fast charging network with 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.

Porsche is sponsoring the Electric Vehicle Symposium
The Electric Vehicle Symposium from October 9 to 11 2017 is the world’s largest industry gathering on the topic of e-mobility. Porsche is sponsoring the event and is also participating as an exhibitor. In addition, the sports car manufacturer is providing numerous experts, who will be able to demonstrate their comprehensive expertise around all things e-mobility. Porsche was the first manufacturer to bring three plug-in hybrid vehicles to market in the premium segment. For several years now, the company has also been gaining valuable experience in the use of hybrid engines at the highest possible level of performance in the LMP1 class of the FIA World Endurance Championship. This experience has enabled Porsche to exhibit a mock-up of an LMP1 racing car at the Porsche EVS stand – the same car that has seen Porsche win the 24 Hours of Le Mans and the FIA World Endurance Championship several times over.

What is this “accumulator-based fast-charging system”?


Super Charger no doubt.

Scott Franco

It means the charger has a battery and takes power off the grid at a relatively slow rate, then dumps it in the car rapidly. Is what you do if the grid can’t deliver the high charging rate current.


Exactly what the Tesla Supercharger does.


Let me get this straight. So here’s a “concept” car that is
– SLOWER 0-60 than a Model S
– Has less than 1/2 the range of a Model S
– Will be available some day instead of today.

Woohoo! Sign me up. Sounds revolutionary!

Someone out there

I’m pretty sure it does Nurburgring way faster than a Tesla. 0-60 isn’t everything.


It will handy extremely well.

Battery Pack sits in the same place the gas engine normally would be.

Neutral handling comes to mind.


A concept, but the short-range, 800V, spec confirms for me that Porsche may be aiming for a sprint EV, or “20-minute” session car.

The Cayman was already mid-engine, which should handle similar in EV trim.


I seriously doubt that it can.


It can. They put the battery back in the middle of the car using the same tabs that held the engine. Then the emotors are on each axle. It is 50/50 weight and will be the best handling in the segment no doubt.


Yeah, really. I know speed is not everything, but it’s a Porshe, and an electric sports car at that. One would have thought they would would have thought of that.


Perhaps this prototype wasn’t trying to push the bleeding edge of acceleration and speed performance. Perhaps this one was about pushing the bleeding edge of fast charging.

Very few prototypes push the “edge of the envelope” in all directions at once.

Go Porsche!


Right, go faster.


Concept probably isn’t the best name for this, more like a technology demonstrator for their 800V system, which is certainly revolutionary and requires a complete redesign of everything that touches high voltage, including the motor, the wires, connectors, the onboard charger, and the 12V DC converter, to name just a few. Even the HVAC would have to be all new as that typically runs directly off the high voltage bus. That also explains why this is being shown at an EV-specific industry event rather than a traditional car show. Way more interesting to me to see something like this than some new pie-in-the-sky concept with arbitrarily fast 0-60 numbers.


That’s the way I see it, too. Calling this a “concept car” is looking at it from the wrong perspective. It’s a prototype, or — as you say — a technology demonstrator.


I am completely convinced 800V is the right way to go. More efficient, more power output (when you want it) and makes very fast (well over 100kW) most cost-effective and easier to deal with through thinner cables and less parasitic heat to try to get rid of.

Thanks to VW (seriously) for pushing this idea. And I hope it takes off rapidly. I don’t think it’ll be available in my budget ranges for the better part of a decade.

I agree, but most EV now are about 400V battery.

I wonder if it’s possible (ie, cheap) to reconfig the batteries to be serially charged and parallel discharge. Batteries cells will see just the same current and voltage, but it would charge at higher power and reduce charging time.

Chris O

If that Mission E really comes with 15 minute charging I think it’s going to be the most important EV after Model S and Model 3. Substantially quicker charging is definitely key to mass adoption.


“… without destroying the battery quickly” and I’ll agree with you.


Porsche has been testing Electric Boxster/Cayman for a solid 5 plus years.

Dual Motor S as well as RWD non S.


So any doubling is turbo?
The accumulative part is the best one.

Since it imply using weak electrical infrastructure, it’s a battery loading and discharging system.


Did they really show and recorded a full charge on a video ? Who can share it ?
Sounds another static show with nothing real happening and just the Marketing repeating Mission E targets without demonstrating any real capability proof.


Are you actually insinuating that Porsche is faking its claim here? Seriously?

Porsche isn’t some wannabe hi-tech battery startup company so desperate for investor money that it puts out vastly inflated claims, like EEStor or Envia. If Porsche is demonstrating an 800-volt, 15 minute EV charging system, then I think it’s safe to believe them. My only real question is what kind of batteries it’s using, because with charging that fast, normal li-ion EV batteries would probably overheat significantly.

My guess is they’re using special battery cells in the car.

Jake Brake

The only way i can see them doing this is to make the car super efficient like the model 3 but use a strong PHEV cell chemistry. You can get higher sustained power outputs for the track but will come up shy on range and cost.


Porsche’s #1 challenge on the EV front is speed to market…

Porsche’s current EV dev-to-production cycle needs to be cut in half meaning they need to for their EVs totally abandon their legacy mentality of ICE car development. Porsche will likely fail at doing that not because lack of desire but because lack of commitment to break away from the legacy Porsche way of doing things.


Since Porsche is not capable of competing with Tesla, perhaps they should do the Ford approach and put a speaker on the outside to make lots of noise so that ppl think that it is quick and fast.

Sans Ice

Ha Ha – yes. It is hard to ignore the 0-60 time from a manufacturer that lives by that stat. That on top of the fact that any offering from Porsche is years away from reality makes the whole thing comical. They are doing lip service to the technology. There has been years of on the road success from Tesla. I don’t believe any of the Germans are all that motivated to participate. When they finally decide to jump in it might be too late. The Tesla roadster will eat all of their lunches. Show me the money! Geez


“…the Mission E’s Porsche Turbo Charging system capable of recharging the battery pack to an 80 percent level in just 15 minutes…

“With a full charge, the unspecified battery pack can last for up to 124 miles (200 kilometers)…”

I wonder, does the “unspecified” battery pack in this prototype use the same sort of li-ion batteries found in today’s production PEVs? Or are they using some kind of non-standard, more expensive battery cells which can be charged faster without overheating?

I’m guessing they’re non-standard.

But how wonderful to see an auto maker working on significantly reducing the time required for a fast charge! As I keep saying, it’s inevitable that competition will continue to reduce fast charge times.

Jake Brake

Glad to see them push 800V, that will drive suppliers to make more 800v components. 3kV hi-pot testing for isolation is no joke.

Finally Porsche got the message and produced.


No point discussing this car. It will never see production. No press will ever test-drive it and verify the specifications claimed.

A sports car that has 125 miles of range in a government test isn’t being driven in a sporting manner. Cars like this are designed to be driven in a sporting manner… check ANY commercial Porsche EVER made for the combustion Cayman. Figure on 50 miles of range during sporty driving.

And as every Tesla owner knows… the best acceleration only happens with 100% battery. After that… it ain’t as fast. So 0-60 in 3.3 seconds ONLY WITH A FULL BATTERY.

No mention of the cost of this car, if it were to be redesigned for actual production. Likely well over $100,000.
