BYD has reduced the fuel consumption (by software update) of its fifth-generation DM (Dual Mode) hybrid technology to just 2.6 liters per 100 kilometers when the battery is depleted, a 10 percent reduction from the previous 2.9 liters.
The fuel efficiency optimization will be provided to all BYD vehicles equipped with the fifth-generation DM technology through over-the-air (OTA) upgrades, the company said.
The fifth-generation DM technology achieves an engine thermal efficiency of 46.06 percent and a combined range of 2,100 kilometers, which is three times that of traditional fuel vehicles, the company said at the time.
The first models equipped with the fifth-generation DM technology were the BYD Qin L DM-i and Seal 06 DM-i, which were launched on May 28 last year, both with a combined range of up to 2,100 kilometers.
Since then, all of BYD's newly launched hybrid models have been based on the latest hybrid technology.
