WHAT IT'S LIKE TO DRIVE A 350 HP 911 WITH A 150 HP AFTERMARKET HYBRID SYSTEM! - ONE TAKE

EV Channels Review

This video review explores the VONNEN Shadow Drive, an aftermarket hybrid system for Porsche 911, Boxster, and Cayman models from 2009 onwards. The system adds approximately 150 horsepower and torque by integrating an electric motor where the flywheel was, along with a front-mounted battery and control unit. The reviewer highlights the system's seamless integration, noting that the car's original ECU is unaware of the modification. While impressed by the added power, especially in the mid-range, and the regenerative braking capabilities, the reviewer points out the significant $75,000 price tag as a major drawback, making it potentially less valuable than upgrading to a factory Turbo model. The system's reversibility and modularity are noted as positives. Ultimately, the reviewer expresses admiration for the technological achievement and its potential, despite the current cost-prohibitive nature for most buyers.
