The fifth-generation DM-i hybrid powertrain is indeed very efficient, but not as much as advertised
BYD introduced the fifth generation DM-I hybrid system a few weeks ago, the first cars based on it were BYD Qin L and Seal 06. Both are capable of driving up to 2100 km on a fully charged and refueled car — BYD says so, but what in reality?
One of the Chinese bloggers took Qin L to check whether the stated data corresponded to the real ones. He went on a short journey by car from the Chinese province of Shaanxi to Guangdong. «Moving» took three days, the air conditioner worked during the trip (it maintained the temperature in the cabin at 24 °C), and in areas where it was allowed, the blogger accelerated to 120 km/h. In other words, the test is quite close to real operating conditions.
As a result, we managed to drive 1977 km: at the 1800 km mark the low fuel level indicator came on, but the blogger drove to the end — until the car stalled.
From this test it follows that in reality the declared power reserve is unattainable, but in comparison with other hybrids, the Qin L is really a kilometer eater, and the average consumption is really low — 3.37 l/100 km. By the way, when refueling the car, 66.74 liters of gasoline fit into the fuel tank — a little more than stated 65 l.
