Toyota’s new 48V mild-hybrid diesel technology: here’s everything you need to know

Toyota Hyundai Motor has revealed more information about its new 48-volt mild hybrid technology, which will be used in diesel-powered pickup trucks and sport utility vehicles (SUVs).

The Japanese manufacturer believes this new system will improve the driving experience, enhance fuel efficiency, and allow for quieter starts compared to traditional gear-based start or stop capabilities. Toyota’s 2.8-litre diesel engine, which powers the Land Cruiser Prado, will first use new 48-volt mild-hybrid technology. It is worth noting that both the Hilux and Fortuner are powered by the same engine in many markets, including India.

The Hilux mild hybrid electric vehicle (MHEV) will debut in the South African and Australian markets next year, Toyota said, while Toyota South Africa also officially announced that the Fortuner and Hilux will offer the technology from 2024.

Toyota’s new 48-volt mild hybrid technology: How does it work?

The mild hybrid system consists of three main components: a belt-driven alternator that replaces the engine’s standard alternator, a 48-volt battery, and a DC-DC converter. Toyota claims this technology will provide more torque assist, smoother starts or stops, regenerative braking, and up to 10 percent higher fuel efficiency compared to diesel-only engines.

Toyota also stated that the new system was designed with off-road driving in mind, so it will not hamper the Hilux and Fortuner’s performance or towing capabilities. It is also possible to wade in water up to 700mm deep thanks to carefully placed components. The report adds that Toyota claims that due to the light weight of the components, the system may also be installed in existing engines.

This mild hybrid technology recently debuted in the new generation Land Cruiser Prado, which will go on sale in North American markets in the coming months. It will debut in South Africa and Australia next year with the next generation Hilux. While Toyota has not said anything about the Indian market, this new 2.8-litre mild-hybrid is expected to debut alongside the new-generation Fortuner in 2024, according to Financial Express.

Toyota has a large fleet of SUVs and multi-purpose vehicles (MPVs) in India, including hybrids like the Urban Cruiser Hyryder, Innova Hycross and Vellfire. Toyota also sells off-road vehicles without hybrid technology, such as the Fortuner, Hilux, and Legend.
