The Zero EV Porsche 911 Conversion Solution
Zero EV, a UK-based company specializing in electric vehicle technology, has developed a bolt-in, plug-and-play electric conversion kit for Porsche 911 models, particularly the 964 generation. This solution is designed to be fully reversible, meaning no permanent modifications to the chassis are required. Owners can enjoy the benefits of electric driving while retaining the ability to restore the car to its original condition if desired.
Key features of the Zero EV 911 conversion kit include:
- Electric motor integration: Replaces the original flat-six engine while retaining compatibility with the 911’s transmission.
- High-voltage battery pack: Optimized to fit within the 911’s layout, offering usable range for modern driving needs.
- CCS Type 2 fast charging: Enables convenient charging at public charging stations.
- OEM-like installation: No cutting or welding required, ensuring the car’s originality is preserved.
- Performance boost: Smooth torque delivery and enhanced drivability, while maintaining the balance and handling characteristics of the 911.
Yes, Converting a classic Porsche 911 to electric is an exciting project. Zero EV offers kits specifically designed for high-performance conversions. Here’s a structured plan for such a build:
Motor Selection
-
Motor Type: High-performance AC synchronous or permanent magnet motor is recommended.
-
Power Rating: Depending on the model and desired performance:
-
Street-level: 200–300 HP (≈150–224 kW)
-
Track-level: 350–450 HP (≈260–335 kW)
-
-
Torque: Ensure the motor provides sufficient torque (≈400–600 Nm) for sporty acceleration.
Battery System
-
Battery Type: Lithium ( LFP) is preferred.
-
Voltage Range: 400–600 V nominal, to balance power delivery and efficiency.
-
Capacity: 50–70 kWh for good range (~150–250 km), 80–100 kWh for extended range or track use.
-
BMS: High-quality Battery Management System to ensure safety, balance, and longevity.
Inverter / Controller
-
Must be compatible with motor voltage and current rating.
-
Should allow regenerative braking if desired.
-
Adjustable parameters for torque and speed mapping help maintain drivability and performance.
Mechanical Integration
-
Transmission:
Retain original manual gearbox for classic feel, or remove for direct motor-to-differential drive (single-speed).
-
Mounting:
Custom motor mounts and adapter plates to fit Zero EV motor into 911 chassis.
-
Cooling:
Motor and inverter require liquid cooling for sustained high-power operation.
Auxiliary Systems
-
12V System: For lights, HVAC, and accessories, use a DC-DC converter from the high-voltage battery.
-
Instrumentation: Speedometer, SOC meter, and other dashboards should integrate with the new EV system.
Safety Considerations
-
High-voltage insulation, fusing, and emergency cut-off switches.
-
Proper cable routing to avoid chafing or short circuits.
-
Thermal management for battery, motor, and inverter.
Advantages of Using a Zero EV Kit
-
Plug-and-play solution: Reduces engineering work.
-
Optimized for classic chassis: Adapter plates, motor mounts, and controller integration are designed for Porsche 911.
-
Performance ready: Delivers instant torque, lower maintenance, and quiet operation.
Cost of a Zero EV Porsche 911 Conversion
The total cost depends on power level, battery size, and customer customization. Based on current market estimates:
-
Base Conversion Kit: $30,000 – $40,000
-
Battery Pack (50–70 kWh): $20,000 – $35,000
