    • Vonnen will make your Porsche 911 a hybrid and add up 351 horsepower with their lightweight electric system

      This is admittedly cool and a new approach. Porsche will eventually develop a hybrid 911 but if you have a spare $75k and want to give your 991.1 911 a big boost in power and torque at a modest weight premium, you will want to look into the Vonnen system.


      Vonnen is run by the guys from Elephant Racing which is regarded as one of the top Porsche 911 suspension tuners. These guys know 911's.

      So what does the Vonnen hybrid system look like?


      Essentially you replace the flywheel with their Motor Generator Unit which depending on whether you get Stage 1 or Stage 2 will add up 351 horsepower.

      The factory electronics are not interfered with:

      Vehicle’s stock ECU is not altered, re-programmed, or interfered with in any manner.

      Smog test results are the same, with or without the Vonnen system installed.

      Fuel costs are greatly reduced when in Virtual EV mode.
      The weight penalty for Stage 1 is 120 pounds and Stage 2 is 190 pounds. Imagine adding the Stage 2 system to a 911 GT3 which would no longer be hurting for torque down low. Or maybe on top of a tuned 911 Turbo S? Things would get nutty in a hurry:


      With the Stage 1 system starting at $75k that does not make this a value project but it certainly makes one think.

      PorscheBoost will contact Vonnen and attempt to visit the facility in the next few months. Suddenly a hybrid 911 does not sound like such a bad thing.

        That doesn’t sound complicated at all. And hey, they’re suspension experts so this is easy. What could possibly go wrong. ¯\_(ツ)_/¯

        Why do you assume they aren't engineers?

        I've been studying this and really, really like the idea but there is no definitive answer on how long the power boost is.

        If it's only 5 seconds as some say, no thanks. If it can't even make it through a full 1/4 mile it's simply not there yet.

        You will also go through clutches faster than you will go through 6 pack of bears in a football night.

        So a lot of increased stress on the PDK?

        Electric motors hit hard and instant. Clutches don’t like instant thrust, they handle progressive loads much better. I bet you will slip the clutch the moment the electric motor kicks in.

        Check Orbis' ring drive solution. I found this more interesting.

        1000 Wh capacity would provide 60 KW for one minute, or about 80 hp.

        So, Stage 1 at 135 KW / 175 hp would last for 27.7 seconds.

        Stage 2 at 350 hp would last under 14 seconds.

        Needs more battery capacity. I wonder how much power it can generate on cruise and on decel.

        If that is true that's not too bad. I can't get a response from these people though to confirm/deny or anything.
