Key Points
1
Horse Powertrain says the B20 can maintain continuous, stable power output during extreme off-road, high-load operation, including climbing gradients of up to 100%.
2
The engine uses a Miller-cycle combustion process, high-pressure direct-injection systems, high-tumble intake ports and specially shaped pistons using the “squish” effect to promote cleaner and faster combustion.
3
Its hardware includes a gantry-style aluminum block with an integrated exhaust manifold, a simplified balance-shaft system and a variable-displacement oil pump, features intended to improve efficiency, durability and noise, vibration and harshness performance.

Horse Powertrain is a joint venture between Renault and Geely and supplies engines, hybrid systems and transmissions to automakers including Renault, Volvo, Geely and Mitsubishi.
5
The B20’s water-fording capability exceeds the published limits of several conventional off-road vehicles: Auto Express compares its 1,100mm rating with 900mm for a Land Rover Defender and 760mm for a Jeep Wrangler, noting that those vehicles’ engines are not entirely waterproof.
Horse Powertrain has unveiled the B20, a 2.0-liter turbocharged engine that can run while completely submerged in up to 1.1 meters of water. Electric Cars Report The engine produces 185 kilowatts and 380 newton-meters of torque while weighing just 130 kilograms. It achieves a claimed brake thermal efficiency of 48.4 percent and is rated IPX8, meaning all electrical components and sensors are fully sealed and protected.
The B20 is designed for hybrid, plug-in hybrid and range-extended electric off-road vehicles. Torque Cafe Its waterproof capability exceeds many conventional off-roaders: Which Car compares the B20's 1,100mm rating with 900mm for a Land Rover Defender and 760mm for a Jeep Wrangler, noting those vehicles' engines are not entirely waterproof.
Built for Extreme Off-Road Conditions
The B20 uses advanced combustion technology to handle extreme terrain. Cars IFU Its Miller-cycle combustion process, high-pressure direct-injection and specially shaped pistons using the "squish" effect promote cleaner, faster burning. Carbuzz The engine maintains continuous, stable power output during high-load operation and can climb gradients of up to 100 percent.
Smart Design Cuts Weight and Noise
Horse Powertrain engineered the B20 for durability and efficiency. Carbuzz It features a gantry-style aluminum block with an integrated exhaust manifold, a simplified balance-shaft system and a variable-displacement oil pump. These features reduce weight, improve noise and vibration performance, and extend engine life during rough use.
First Model: Geely Galaxy Cruiser 700
The B20's first known application is the China-only Geely Galaxy Cruiser 700. Torque Cafe Though the engine can handle 1.1 meters of water, the Cruiser 700's own maximum wading depth is rated lower. Electric Cars Report Horse Powertrain is a joint venture between Renault and Geely, supplying engines to Renault, Volvo, Geely and Mitsubishi.
