BYD Seal06 DM-i PHEV: A complete look at the plug-in hybrid car scheduled to arrive in Japan in 2025

The Seal 06 DM-i, a plug-in hybrid vehicle (PHEV) developed by Chinese electric vehicle manufacturer BYD, is scheduled to be introduced to the Japanese market in December 2025. BYD is often thought of as an electric vehicle (EV) manufacturer, but it is also a pioneer in developing the world’s first mass-produced PHEV . The F3DM, released in 2008, is proof of this, with one in every two PHEVs sold in China now being a BYD vehicle.

The Seal 06 DM-i is part of the same Seal series as the electric vehicle “Seal” that was previously introduced in Japan, but it is a plug-in hybrid vehicle that has improved usability by adopting a special body design.

What is the BYD Seal06 DM-i? Why is its entry into the Japanese market attracting attention?

Demand for PHEVs in the Japanese market and BYD’s strategy

As the shift to EVs continues globally, PHEVs are thought to have the potential to become more popular in the Japanese market . This is because, taking into account the state of charging infrastructure and the way Japanese people use their cars, PHEVs are likely to be a more practical option.

The innovative nature of 5th generation DM-i technology: world-class technological capabilities

Breakthrough thermal efficiency and fuel economy

On May 28, 2024, BYD unveiled its fifth-generation DM-i technology in Xi’an. The technology’s greatest feature is its world-leading thermal efficiency of 46.06% , a groundbreaking figure that significantly exceeds the thermal efficiency of the previous fourth-generation DM-i, which was 43.04%.

Specific fuel economy figures:

• Sedan model: 2.9L/100km (approx. 34.5km/L) – 3.08L/100km (approx. 32.5km/L)
• Wagon model: 3.15L/100km (approx. 31.7km/L) – 3.35L/100km (approx. 29.9km/L)

A total cruising range of over 2,100 km

The greatest attraction of the fifth-generation DM-i technology is its combined range of over 2,100km , a groundbreaking achievement that delivers three times the range of a conventional car while consuming one-third the fuel.

On the BYD official website , Chairman and President Wang Chuanfu emphasized that “BYD is at the forefront of PHEV technology in the global market,” demonstrating that this technological innovation is the company’s competitive advantage.
