Hollywood star Jason Momoa best known for his roles in Aquaman, Dune, and Game of Thrones, has always had a passion for classic craftsmanship. Recently, he took that passion to the next level by commissioning a groundbreaking electric conversion of his vintage 1929 Rolls-Royce Phantom II.

The Partner: Electrogenic

To pull off this “dream project,” Jason Momoa turned to Electrogenic, a world-leading EV technology company based in Kidlington, Oxfordshire. Known for their “sympathetic” conversions, the team spent 18 months transforming the nearly century-old icon.

“I needed a team that would appreciate the storied history of this car while updating its technology,” Momoa explained. “Electrogenic is all about honouring classic cars and making them electric without losing any of the vehicle’s character.”

Engineering the “Unbearable”

The Phantom II was originally powered by a massive 7.7-litre pushrod straight-six engine. Electrogenic replaced this with a 93kWh battery pack and a high-performance electric powertrain.

The result? A car that is now:

• Four times more powerful than the original (delivering 150kW/201hp).
• Weight-neutral, meaning the new components didn’t add bulk to the two-tonne chassis.
• Capable of 150 miles of real-world range on a single charge.

The conversion wasn’t just about the motor; it was a “labour of love” that required re-engineering the car’s complex cable-operated braking system and its famous “through-flow” chassis lubrication system to work with modern EV architecture.

Modern Comforts, Vintage Soul

While the exterior remains a masterpiece of 1920s design, the interior received subtle modern upgrades. The original gauges were creatively repurposed, the fuel sight glass is now an LED battery indicator and a high-end, multi-speaker Bluetooth audio system was discreetly hidden within the leather and wood-lined cabin.

The entire process was filmed for Momoa’s new Discovery+ series, “On The Roam,” showcasing the incredible intersection of heritage and future-proof technology.

What Do You Think?

Converting a classic Rolls-Royce to EV: A stroke of genius by Jason Momoa, or should it have stayed original? While some see it as preserving history for the next generation, others miss the smell of petrol and that iconic engine note.
