This Diesel-Electric Golf Cart with Dual Engines is likely the only one of its kind in existence.

Modifying golf carts has become popular, and we fully support it. They are straightforward, have a wealth of aftermarket options, and don’t have to comply with safety or emissions regulations. What’s not to appreciate? The creators of the Robot Cantina channel on YouTube showcased remarkable creativity by constructing a hybrid golf cart in 2024, and they’ve now returned with another hybrid powered by gasoline, diesel, and electricity.
Originally, this older three-wheeled Cushman golf cart runs on a typical electric drivetrain, which includes a battery pack and an electric motor. Robot Cantina's initial aim was to swap out the heavy batteries for an on-board generator to create a hybrid. This is similar to the type of drivetrain used in the Ram 1500 Ramcharger. The builder crafted the powertrain from scratch utilizing a 196cc single-cylinder diesel engine, a 140-amp alternator from a Jeep Liberty, and extensive wiring. While the system functioned as planned, it lacked sufficient power.
The straightforward solution would have been to install a larger engine, but Robot Cantina chose to retain the diesel engine. The final product could potentially be the world’s first twin-engined gasoline-diesel-electric hybrid golf cart. The gasoline component features a large 420cc single-cylinder Predator engine that Robot Cantina modified for fuel injection to operate a first-generation Honda Insight. It regained its carburetor before being mounted onto the Cushman, and like the diesel, it is connected to a Jeep Liberty alternator with altered wiring.
Assembling everything was more challenging than depicted in the video. According to Robot Cantina, the project required around two days. They had to modify a power steering pump pulley to function as a crankshaft pulley, create a bracket for the belt tensioner, and drill a mounting plate from a thick steel piece. The entire process is notably experimental, yet the attention to detail is impressive. For instance, Robot Cantina took the time to trim excess material from the alternator belt tensioner’s bracket and paint it.
Though the 420cc engine is secured and attached to the motor, there are still some issues to resolve. One is that it's currently operating the motor independently since the diesel engine was temporarily disconnected. Additionally, the golf cart malfunctioned during its initial road test and needed to be towed back to the shop by an eye-catching first-generation Chevy S-10. We believe it won’t take long to get everything working smoothly.
