Classic Porsche 911 owners can now breathe fresh life into their iconic sports cars without sacrificing their unique charm. These innovative electric vehicle (EV) conversion kits replace the gas engine with electric power while retaining the 911's iconic design and driving dynamics. This provides the environmentally friendly benefits of electric driving while preserving the 911's lively acceleration and exhilarating driving experience. Our team at Porsche Livermore explores the benefits of the 911 EV conversion kit to help you decide whether this switch is right for you.
What Is a Porsche 911 EV Conversion Kit?
A Porsche 911 EV conversion kit serves as an electric upgrade for your classic sports car, substituting its traditional gasoline engine with electric motors, batteries, and control systems while retaining the body, interior, and chassis. Companies such as Everrati, Fellten, and Electrogenic offer complete bolt-in packages that preserve your car's character while adding modern electric power.
These kits are completely reversible — you can restore the factory specifications, protecting your car's resale value. Porsche 911s are ideal candidates for this upgrade due to their air-cooled design, which allows for compact drive units without compromising the iconic shape.
Key Components of the Conversion Kit
Fellten's kit features an upgraded Tesla Model S drive unit that produces 440 horsepower and 339 lb-ft of torque, while the dual battery packs offer a combined capacity of 62 kWh. These components integrate seamlessly into the car's existing framework, eliminating the need for welding or structural modifications.
The complete kit includes the Speedhut five-gauge package, billet aluminum drive selector, fly-by-wire throttle, and positive temperature coefficient cabin heater. This kit offers 200 miles of range and fast-charging from empty to 80% in just one hour. Two liquid cooling systems regulate the temperature of the batteries and the drive unit.
The Everrati Porsche 993 Founders Edition delivers 760 horsepower and 597 lb-ft of torque, accelerating from 0 to 60 mph in 3.3 seconds and offering a range of 200 miles.
The Installation Process
Installing a 911 EV conversion kit requires precision and expertise. First-time installations typically require approximately 100 hours of shop time, excluding restoration work. Behind each kit lies roughly 500 hours of development over six months, explaining their perfect fit. European regulations require genuine drop-ins that use the original mounting points without cutting, welding, or drilling, ensuring upgrades remain reversible and structurally sound.
Professional installation costs over $120 per hour but also takes care of technical challenges and the necessary paperwork. Legal requirements vary by location. Classics converted in the European Union may qualify for historic status, allowing them to bypass emissions tests while still requiring safety inspections.
In the United States, regulations are more lenient. Most states only check the vehicle identification number. California enforces stricter guidelines that may include additional inspections. The total cost of these kits ranges from $20,000 for basic setups to $150,000 for fully restored 400-horsepower versions. Shipping requires specific documentation, such as UN 38.3 Battery Test Summaries and disconnection certificates.
Performance and Driving Experience After Conversion
When you step on a converted 911's accelerator, you'll notice the difference. Although the familiar roar of the BOXER engine is replaced by a quiet electric hum, a converted 964 can accelerate from 0 to 60 mph in 4.1 seconds, which is quicker than the original. Electric motors generate immediate maximum torque. Although some conversions, such as Electrogenic's XKE, significantly reduce horsepower, they nearly double the torque from 285 lb-ft to 475 lb-ft for a more exhilarating drive.
These electric classic cars compete well with modern Porsche models. Everrati's electric 964 accelerates from 0 to 60 mph in under 4 seconds and offers a range of 200 miles. The 2025 Porsche 911 Carrera produces 388 horsepower, sprinting from 0 to 60 mph in 3.9 seconds, while the 2025 Carrera 4 GTS achieves this in 2.9 seconds and generates 532 horsepower and 420 lb-ft of torque. Everrati's 964 RSR conversion delivers 500 horsepower and 369 lb-ft of torque, accelerating from 0 to 60 mph in 3.7 seconds and offering a range of 200 miles. Porsche's electric Taycan GTS produces 690 horsepower.
