Silicon Valley-based hybridization shop Vonnen and Wisconsin custom builder Kelly-Moss have partnered to create this unreal 2014 Porsche 911 Turbo S Hybrid.

Vonnen has used their plug-and-play hybrid kit in this thing to give it an electric boost.

Founded in 2016, Vonnen has developed the Shadow Drive retrofit electric kit for Porsche 911, Boxster and Cayman. The 170-lb (77-kg) kit replaces the factory flywheel with a slim electric motor-generator hooked up to a liquid-cooled battery pack mounted ahead of the front axle. With help from the control unit monitoring driving conditions, the motor spins up to 9,000 rpm to augment the engine's power and torque, adding up to 150 hp and 150 lb-ft (203 Nm). The battery system is optimized for rapid charging and discharging, relying on regenerative braking to keep charged.

Actual performance numbers will vary by specific 911 model, but, citing Road & Track calculations, Vonnen estimates that a 350-hp 991 Series 911 will see its 0-60 mph (96.5 km/h) cut by a second, down to 4 seconds flat, with the Shadow Drive dialed to street mode. When punching up to overdrive mode, that time drops to 3.6 seconds. Check out Vonnen's performance page for additional metrics.

Have they actually built any of these? I'd love to read a review or watch a YT video of it.

I haven't seen videos of this specific 911 but there are videos of the Vonnen hybrid system in other 911s.

Here's one from Vonnen that explains how their hybrid system works.


Here's a video of a Vonnen 2013 911 Carrera that Porsche Club of America test drove.
