The new Toyota Hilux Hybrid 48V pickup truck with a mild-hybrid system

The Toyota Hilux is one of the most popular and reliable pickups in the world, with a reputation for being tough, durable, and versatile. But what if it could also be more efficient, responsive, and refined? That’s the promise of the new Hilux Hybrid 48V, a mild-hybrid system that enhances the performance and economy of the 2.8-litre turbo-diesel engine. We will explore how the new Toyota Hilux Hybrid 48V works, its benefits, and how it compares to its competitors.

What is a mild-hybrid system?

A mild-hybrid system is a type of electrification that uses a small electric motor-generator and a 48-volt battery to assist the combustion engine in various situations. Unlike a full-hybrid system, a mild-hybrid system cannot power the vehicle solely on electric mode but rather provides a boost of torque, reduces fuel consumption, and improves drivability.

The mild-hybrid system is integrated into the existing 12-volt electrical system of the vehicle and does not require any changes to the transmission, drivetrain, or chassis. The system is also relatively lightweight and compact, adding only about 15 kilograms to the vehicle’s weight.

How does the Toyota Hilux Hybrid 48V work?

The 2024 Toyota Hilux Hybrid 48V pickup truck consists of four main components: the 2.8-liter turbo-diesel engine, the six-speed automatic transmission, the 48-volt battery, and the electric motor-generator. The system works in three ways:

• Regeneration: When the vehicle is coasting or braking, the electric motor-generator acts as a generator and converts kinetic energy into electrical energy stored in the 48-volt battery. This reduces the load on the engine and the brakes and saves fuel.
• Assistance: When the vehicle accelerates or climbs, the electric motor-generator acts as a motor and provides additional torque to the engine, up to 20 Nm. This improves the responsiveness and performance of the vehicle and reduces the turbo lag and engine noise.
• Stop-start: When the vehicle is idling, the electric motor-generator automatically turns off the engine and restarts it smoothly when the driver releases the brake pedal. This reduces the fuel consumption and the emissions of the vehicle and also enhances the comfort and refinement.

What are the benefits of the Hilux Hybrid 48V?

The Hilux Hybrid 48V pickup truck offers several benefits to the drivers and the environment, such as:

• Fuel efficiency: The Hilux Hybrid 48V reduces the fuel consumption of the 2.8-liter turbo-diesel engine by around 10 percent, from 8.4 L/100 km to approximately 7.6 L/100 km. This translates to an annual saving of about $300, based on an average driving distance of 15,000 km and a diesel price of $1.5 per liter.
• Performance: The Hilux Hybrid 48V enhances the performance of the 2.8-litre turbo-diesel engine, which already delivers 150 kW of power and 500 Nm of torque. The system provides a smoother and more linear acceleration, and improves the engine braking when driving off-road. The system also maintains the 3500-kg braked towing capacity and the 4x4 capability of the Hilux.
• Refinement: The Hilux Hybrid 48V pickup truck improves the refinement of the 2.8-litre turbo-diesel engine, which is already one of the quietest and most refined in its class. The system reduces engine noise, vibration, and harshness and provides a more seamless and comfortable driving experience.
