Electric Vehicle Conversions: Preserving Classic Cars With Modern Technology
Electric vehicle conversions are gaining popularity in the automotive world as a way to update classic cars with modern technology while preserving their original charm. Nomad Motors, a shop run by Keith Martin in Midcoast Maine, specializes in converting classic vehicles using electric drivetrain components. In this article, we will explore the process of converting classic cars to electric power, focusing on Martin’s journey with a 1976 BMW 2002.
### Keith Martin and his 2002
Keith Martin’s passion for classic cars and desire to spend more time driving rather than fixing them led him to start Nomad Motors. The shop collaborates with industry veterans to convert classic cars into electric vehicles, offering customers a more reliable and enjoyable driving experience. Martin’s own BMW 2002 conversion serves as a testament to the capabilities of electric drivetrain components in enhancing performance and usability.
### The Conversion Process
The conversion of Martin’s 1976 BMW 2002 involved replacing the stock engine with a Netgain Hyper 9HV electric motor, which significantly improved the car’s horsepower and torque. The conversion also included a full-body restoration before installing the electric drivetrain, resulting in enhanced performance and efficiency. The manual transmission of the BMW was retained, providing a more engaging driving experience and a unique feature not commonly found in modern electric vehicles.
### Power Source and Components
The electric motor in the BMW 2002 is powered by six liquid-cooled Tesla 18650 batteries wired in series, with a total pack voltage of 144 volts and a 32-kWh capacity. The vehicle features a sealed HV junction box containing essential switches, fuses, and service disconnects for safety. Additionally, components such as a DC-DC voltage converter and electric heating element were installed to power low-voltage systems and maintain driver comfort.
### Chassis and Handling Modifications
To accommodate the electric drivetrain, chassis modifications were made to support the added torque and weight distribution. The positioning of the battery pack in the trunk and adjustments to the front end and suspension helped maintain the car’s balance and handling characteristics. With the installation of upsized anti-sway bars and wider tires, the BMW 2002 retains its original charm while offering improved performance and stability on the road.
### Cost and Future of Electric Conversions
The cost of converting a classic car to an electric vehicle can range from $20,000 to $60,000, depending on the desired specifications and components. Nomad Motors offers conversions for various classic vehicles, including Porsche models, VW Beetles and Buses, and Land Rover Defenders. As technology advances and parts for classic cars become scarce, electric conversions could be a sustainable way to keep these vehicles on the road for years to come.
Electric vehicle conversions offer a unique blend of modern technology and classic design, providing classic car enthusiasts with a practical and reliable driving experience. Nomad Motors and Keith Martin’s dedication to preserving the original charm of classic cars while upgrading their performance exemplify the future of automotive restoration and customization. Through innovative conversions and a commitment to quality craftsmanship, electric vehicles are transforming the way we experience and appreciate classic cars in the 21st century.
