Horse B20 features a 2.0-liter gas-powered turbo—one of the prevalent types of car engines in today’s market—with a special feature: it’s waterproof. This engine can function fully immersed in nearly four feet of water.
Horse Powertrain provides a variety of engines to OEMs and is well-known for producing engines that support hybrid powertrains (the gasoline element in PHEVs and EREVs). Essentially, the B20 is a direct-injection turbo four-cylinder designed to power hybrid trucks and SUVs suited for off-road use.
This makes perfect sense for 2026. Brands like Land Rover, Jeep, and Toyota have been advertising off-road vehicles with hybrid power for several years; they all highlight their water-fording capabilities in specifications and marketing.
In truth, Jeep moved away from hybrids this year, but it’s uncertain if that will be a permanent decision.
To summarize—hybrid combined with 4×4 is unquestionably a current trend, which is not surprising and still exciting to witness this type of off-road-oriented innovation. Waterproofing is beneficial not only for crossing rivers; it also provides extra protection against splashes and varying weather conditions.
Horse is a collaboration between parent companies Renault and Geely, and a variant of the B20 is already offered in the large, boxy 1,113-horsepower Geely Galaxy Cruiser 700. While it may not fully utilize the B20’s capability for a 1.1-meter immersion, it remains an impressive vehicle with a maximum wading depth of nearly 35 inches.
Geely Cruiser 700 Can Actually Float
Chinese car names are wonderfully entertaining. It’s as if they glanced at a Toyota dealership across the way and said, “Land Cruiser, really? Well, we’re introducing a Galaxy Cruiser, take that!”
In actuality, it’s a pretty striking SUV. The design leans more towards Land Rover than Land Cruiser, but the interior boasts appealing knobs and switches. I genuinely believe it surpasses LR’s own Defender in looks.
Regarding the B20, the IPX8 waterproof rating (certifying it for functionality under 1.1 meters, roughly 3.6 feet, of water) is accomplished through a fully sealed framework. It includes torsional vibration dampers and specific engine-transmission sealing. IPX8-rated sensors observe the surroundings, and when submerged, the control system automatically restricts power or modifies throttle response based on the sensor data.
That combination—not only wading through water but also maintaining operation while entirely underwater, with dynamic electronic management of the submersion—is the intriguing aspect.
The Horse B20 has a weight of approximately 287 pounds, utilizing a gantry-style aluminum block with an integrated exhaust manifold and a streamlined balance shaft system (to enhance NVH, durability, and overall efficiency).
High-pressure injectors and high-tumble intake ports are installed to encourage “superior air-fuel mixing and greater combustion efficiency.” Horse’s press release also highlights that “the engine features pistons engineered to fully leverage the ‘squish’ effect to improve air-fuel mixing at the peak of the compression cycle” for “cleaner and quicker combustion.”
Horse indicates power outputs ranging from 188–248 hp, and 221-280 lb-ft of torque.

### Waterproof Gas Engine Tailored for Underwater Functionality
#### Introduction
The creation of waterproof gas engines intended for underwater functionality signifies a major breakthrough in marine technology. These engines are designed to operate effectively not only above the surface but also below, expanding their applications in marine exploration, underwater construction, and leisure activities.
#### Design Features
1. **Sealed Components**: The waterproof gas engine contains sealed components to avert water ingress. This includes specially engineered gaskets and seals that safeguard critical elements like the ignition system, fuel system, and exhaust.
2. **Corrosion-Resistant Materials**: To endure the tough underwater environment, these engines are made from corrosion-resistant materials such as stainless steel, aluminum alloys, and specialized coatings that prevent rust and decay.
3. **Cooling System**: The cooling system is modified for underwater utilization, using water as a coolant instead of air. This maintains optimal operating temperatures while avoiding overheating, essential for sustaining engine performance during extended underwater operations.
4. **Fuel Efficiency**: Sophisticated fuel management systems are included to optimize fuel consumption, ensuring that the engine runs efficiently at different depths and pressures. This is particularly vital for lengthy missions where refueling might not be an option.
5. **Pressure Resistance**: The engine is crafted to withstand the higher pressures encountered at greater depths. This involves reinforced casings and pressure-tested elements that guarantee reliability and safety during operations.
#### Applications
1. **Marine Exploration**: Waterproof gas engines can power submersibles and underwater drones, allowing researchers to investigate ocean depths, examine marine ecosystems, and conduct geological surveys.
2. **Underwater Construction**: These engines can be employed in underwater construction endeavors, such as creating artificial reefs, repairing submerged pipelines, or executing salvage tasks, where conventional electric motors may lack sufficient power or reliability.
3. **Recreational Use**: The engines can also be adapted for recreational vehicles like underwater scooters and personal submarines, enabling enthusiasts to explore aquatic environments with increased freedom and distance.
4. **Military and Defense**: In defense scenarios, waterproof gas engines can augment the capabilities of submarines and unmanned underwater vehicles (UUVs), providing reliable energy for surveillance, reconnaissance, and tactical operations.
#### Challenges and Considerations
Although the prospects for waterproof gas engines are extensive, several challenges need to be navigated:
– **Weight and Buoyancy**: The design must find a balance between the engine’s weight and buoyancy requirements to ensure that vehicles stay maneuverable underwater.
– **Noise Reduction**: Gas engines generally produce more noise than electric counterparts, which can be problematic in sensitive marine habitats. Innovations in muffling technology are essential to reduce acoustic signatures.
– **Environmental Impact**: Utilizing gas engines underwater raises concerns regarding fuel leaks and emissions. Developing eco-friendly fuels and ensuring robust containment systems are crucial to mitigate environmental issues.
#### Conclusion
The waterproof gas engine designed for underwater operation signifies a groundbreaking step in marine technology, presenting new possibilities for exploration, construction, and leisure. As innovations progress, these engines are likely to become vital in enhancing our understanding of underwater ecosystems and improving human capabilities in marine settings.
