The Mars II Electric: A 1968 EV Ahead of Its Time

A converted Renault R10, the Mars II Electric was a pioneering electric vehicle (EV) that emerged from Detroit in the late 1960s. Created by Electric Fuel Propulsion (EFP), this innovative car was a glimpse into the future of automotive technology.

Although many early EVs remain obscure, the Mars II Electric stands out as a testament to early ingenuity in electric propulsion. This article delves into the history and significance of the Mars II Electric, highlighting its advanced features and potential as a modern restomod project.

A Pioneering Electric Vehicle

The Mars II Electric was based on the Renault R10, a French compact car, and was one of just 45 units built by EFP. Founded in Detroit, EFP was at the forefront of EV technology during the 1960s and continues today as Apollo Energy Systems, a manufacturer of batteries and fuel cells. The company later created the Electrosport, an electric version of the AMC Hornet intended for mass production. Despite these advancements, the Mars II Electric primarily served utility companies, showcasing the potential of electric power in an era dominated by internal combustion engines. The Renault R10 itself was an interesting base for an electric vehicle conversion. Known for its rear-engine, rear-wheel-drive layout, the R10 offered a spacious engine bay and ample weight distribution for battery placement. The Mars II Electric retained much of the R10’s original design, but the internal combustion engine was replaced with an electric motor and a series of lead-acid batteries. This setup was innovative at the time, considering the limited technology and understanding of electric vehicles in the 1960s.

Advanced Features and Capabilities

The Mars II Electric boasted impressive specifications for its time, with a range of around 120 miles, the ability to reach highway speeds, and the capability to charge up to 80 percent in just 45 minutes at 50 kW. Additionally, it featured regenerative braking, a technology that would not become common in EVs until decades later. EFP founder Robert Aronson undertook several well-publicized road trips in a Mars II, collaborating with utility companies to establish charging points. Despite the technology’s viability, the widespread adoption of EVs was hindered by the affordability and prevalence of combustion engines, even during the fuel crises of the 1970s. The regenerative braking system in the Mars II Electric was particularly groundbreaking. This technology allows the vehicle to recover energy during braking, converting kinetic energy back into stored electrical energy in the battery. This not only extends the driving range but also improves the overall efficiency of the vehicle. In an era where electric vehicle infrastructure was virtually non-existent, such innovations were truly ahead of their time.

A Project Car with Modern Potential

This particular Mars II Electric, currently up for auction on Bring A Trailer, is a non-running project car with only four of its original 20 six-volt batteries remaining. Built from a complete Renault R10, the car itself is a fascinating piece of automotive history. The fact that it is an EV from before the moon landings adds to its historical significance. However, this Mars II Electric doesn’t have to remain a static exhibit; it has the potential to be revived as a modern, high-performance EV. The potential for converting this Mars II Electric into a modern EV is immense. With advancements in battery technology and electric motors, the car could be outfitted with a lithium-ion battery pack, significantly increasing its range and performance. Companies like EV West specialize in converting classic cars to electric power, often using components from modern EVs like the Tesla Model S. A conversion like this would not only preserve the historical significance of the Mars II Electric but also bring it into the 21st century with state-of-the-art technology.

Resurrecting Life on Mars

Thanks to the growing popularity of classic car EV conversions, there are numerous options for bringing the Mars II Electric back to life. Companies like EV West, which specialize in converting vintage vehicles to electric power, could transform this historic car into a modern powerhouse. With a Tesla-sourced lithium battery pack and a contemporary electric motor, the Mars II Electric could be reimagined with tire-smoking performance. Its rear-engine, rear-wheel-drive layout makes it an ideal candidate for such a conversion, offering a unique blend of vintage charm and cutting-edge technology. EV conversions have become increasingly popular as enthusiasts seek to combine the charm of classic cars with the benefits of modern electric drivetrains. The Mars II Electric, with its lightweight chassis and classic design, is a perfect candidate for such a project. A modern electric motor would not only improve performance but also enhance reliability and reduce maintenance costs. Additionally, the use of regenerative braking and advanced battery management systems would further optimize the vehicle’s efficiency and driving experience.

Conclusion

The Mars II Electric from 1968 is a remarkable example of early electric vehicle innovation. Its advanced features and capabilities were ahead of its time, and with modern EV conversion techniques, it has the potential to become a high-performance restomod. This pioneering EV serves as a reminder that the future of automotive technology has roots in the past, and the Mars II Electric is a testament to the enduring appeal and potential of electric propulsion. Whether you’re a vintage car enthusiast or a modern EV aficionado, the Mars II Electric is a fascinating piece of automotive history worth celebrating.
