BYD DM-I technology
BYD showcased the DM-I technology in India yesterday. DM-I means Dual Mode Intelligent. This technology has been in production since 2008. BYD has put in 18 years of R&D into the tech and has sold over 8 million DM vehicles.
What is this DM-I technology?
BYD just showcased their DM-i (Dual Mode Intelligent) technology in India yesterday, and it is worth paying attention to. Backed by 18 years of R&D and over 8 million DM vehicles sold globally since its initial production in 2008, this is a highly mature platform.
So, what exactly makes DM-i different? Unlike traditional plug-in hybrids that simply tack an electric motor onto a gas engine, DM-i operates with an electric-first philosophy. The high-power electric motor drives the wheels most of the time, while the gasoline engine acts primarily as a generator to charge the battery. The engine only directly powers the wheels during high-speed cruising, which is its most efficient operating window.
The Four Driving Modes
EV mode: Depending on battery size, the car covers 70 to 100 kilometers using only electric power.
Series mode: When the battery runs low, the petrol engine turns on to act strictly as a generator, charging the battery that powers the electric motor.
Parallel mode: When you need rapid acceleration, both the electric motor and the petrol engine work together to push the car forward.
Power split mode: Designed for highway cruising, the engine drives the wheels directly while simultaneously recharging the battery.
If those last three modes sound familiar, it is because they function very similarly to the strong hybrid implementations. For Indian buyers waiting to experience this setup firsthand, BYD has officially announced that the Seal U will be the first product to launch here with DM-i technology.
How are PHEVs doing around the world?
China
When we look at recent retail data, the momentum heavily favors pure battery electric vehicles. According to recent CPCA data reported by CNEVPost, BEVs are currently surging globally. In April and May of 2026, BEV sales decisively beat the figures recorded in both 2024 and 2025. In stark contrast, overall PHEVs are losing their footing. Over the last five months, China PHEV and EREV sales have struggled to even match their 2024 baseline numbers. Rather than acting as a growing transition technology, the data indicates that consumer interest in traditional PHEVs might have already peaked in China, with buyers opting to jump straight into fully electric models instead.

Europe
The trend becomes even clearer when we zoom in on Europe, a region historically open to hybrid technologies. Data from the International Council on Clean Transportation (ICCT) covering January to April 2026 paints a definitive picture of consumer preference.
During this period, BEVs captured a commanding 21% market share across Europe, representing a solid 4 percentage point increase from the previous year. Meanwhile, PHEVs managed to hold onto just a 10% market share, growing by only 2 percentage points year-over-year. Not only are BEVs leading in absolute market penetration, but their growth rate is double that of their plug-in hybrid counterparts.

If we look at April 2026 sales numbers, there are only 5 models in the top 20 that are PHEV or BEV+PHEV

UK
In the UK as well, BEVs are gaining much more traction as compared to PHEVs. In May'26, BEVs had a 27.3% market share, up from 21.8% last year, and PHEVs had a 13.8% market share, up from 11.9% last year

Looking Ahead for India
Numbers do not lie. While PHEVs might look great on paper as a compromise for the Indian market, global consumers are increasingly viewing them as an unnecessary middle step. Automakers try to pass off this transitional hybrid tech as the future. As battery prices continue to drop and global EV technology improves, pushing for PHEVs in India might mean investing heavily in a transitional technology that the rest of the world is already leaving behind.
