Vallejo, California – October 7, 2025 — Kindred Motorworks has taken a major step in classic car electrification with the delivery of its first Bronco EV Edition and the official launch of the Grayback Electric Vehicle Platform (EVP), an in-house–developed electric platform five years in the making.
Named after the USS Grayback (SSG-574), a U.S. Navy guided-missile submarine built at Mare Island — where Kindred is headquartered — the new platform represents a technological leap in the electric conversion sector. The Grayback EVP was designed to integrate advanced electric powertrains into virtually any classic car or truck, combining top-tier commercial components with controls and parts engineered by Kindred itself.

According to the company, the system is the most advanced in its class worldwide, managing heating, cooling, power distribution, battery control, and charging, with OEM-level performance and reliability.
“The best platform for electric conversions of classic vehicles”
“Customer interest in our electric prototypes is off the charts,” said Rob Howard, founder and CEO of Kindred Motorworks. “We knew we needed a platform that exceeded expectations — and the Grayback EVP does exactly that. It’s the best-in-class platform for converting classic vehicles to electric power, and the Kindred EV Bronco is the perfect launch vehicle to showcase its reliability and performance.”
The modular battery design, based on high–energy-density modules, allows the system to be tailored to the constraints of each classic model. The Grayback EVP offers multiple motor configurations, supporting everything from all-wheel drive to high-performance road setups, without compromising safety or comfort.
200-mile range and up to 600 horsepower
The thermal management system developed by Kindred optimizes the temperature of the battery, motor, and high-voltage inverters, ensuring maximum performance and component longevity, while also providing efficient air conditioning and heating.
Vehicles equipped with the Grayback EVP promise a range of up to 200 miles (320 km) and power outputs of up to 600 horsepower, with quiet operation and virtually zero maintenance. In addition, the modular architecture allows for future upgrades as battery technologies evolve.
The integrated charging system is compatible with both home AC charging and fast CCS DC charging, offering intelligent battery monitoring and automatic performance adjustment based on environmental conditions, ensuring the fastest possible charging in any situation.
The future of electric classics
With the Grayback EVP, Kindred Motorworks says it is reinforcing its mission to create modern, reliable classic vehicles that combine historic design with cutting-edge electric propulsion.
“Our platform was designed to preserve the spirit of classic cars, but with the reliability, safety, and performance of a modern electric vehicle,” concluded Rob Howard.
The Kindred EV Bronco, the first model to roll off the production line equipped with the new technology, marks the beginning of a new era for classic car enthusiasts — now ready for an electric future.
