BYD Qin PLUS DM-i claims to consume 3.8L of fuel on power. How much is it actually measured? The result is quite surprising

On the evening of January 11, BYD officially announced that the pre-sale of the new sedan Qin PLUS has officially started. There are four models in total, with a pre-sale price of 107,800-147,800 yuan. It will be officially launched in early March this year.

The biggest highlight of the new car is the power part. It will be equipped with BYD's latest DM-i plug-in hybrid system, which consists of a 1.5L naturally aspirated engine + electric motor. Among them, the 1.5L high-efficiency engine dedicated to Xiaoyun-plug-in hybrid has an engine thermal efficiency of up to 43.03%.

Officials said that even when the battery is low, it can still achieve a low fuel consumption of 3.8L/100km, while the Ministry of Industry and Information Technology's fuel consumption is only 0.7L/100km; the acceleration from 0 to 100km/h is only 7.3s, and the comprehensive cruising range can reach 1245km.

So, how strong is the vehicle's actual fuel consumption? Some media have already conducted fuel consumption tests on it.

The main purpose of the fuel consumption test is to simulate the actual fuel consumption performance of users in real usage scenarios with power supply without being plugged in.

At the beginning of the test, the vehicle's battery SOC was 25% (i.e. only 25% of the battery power), and the energy feedback level was adjusted to the maximum. The driving mode was ECO, there were three people in the car, the air conditioner was 22℃, the second gear wind volume, and the outdoor temperature was 6, 7℃. The test vehicle was the Qin PLUS standard endurance version (pure electric range 55km version).

At the beginning, the vehicle's fuel tank was full and it traveled a total of 108.4 km through Shenzhen Expressway, urban expressway, and congested sections of the city.

As a result, the second time of refueling, the amount of fuel filled was 3.65L, which is equivalent to a comprehensive fuel consumption of 3.37L/100km, which is much lower than the official nominal fuel consumption of 3.8L/100km, which is quite amazing.

In addition, the representatives of joint venture brand family cars, Sylphy and Lavida, also competed in the segment, achieving the best fuel consumption results of 4.68L/100km and 5.4L/100km respectively.

In terms of acceleration performance, the BYD Qin PLUS DM-i standard range version can accelerate from 0 to 100 km/h in 7.9 seconds, while the long range version can accelerate from 0 to 100 km/h in 7.3 seconds.

Compared with Toyota and Honda's hybrid models, BYD Qin PLUS has obvious advantages in fuel consumption and power. So, how did BYD do it?

According to official introduction, in the DM-i super hybrid system, the drive motor undertakes most of the work and acceleration conditions, while the engine does the least and most fuel-efficient work.

In pure electric mode, the high-energy DM-i super hybrid dedicated power blade battery is responsible for powering the drive motor.

In most hybrid modes, the engine drives a high-power generator to supply power to the drive motor. In medium and high-speed driving conditions, the engine directly drives or drives the motor at the right time, and outputs power in parallel.

In addition, in order to achieve lower fuel consumption, this 1.5L Xiaoyun plug-in hybrid engine has a compression ratio of up to 15.5, and the air-conditioning compressor, vacuum pump and other accessories are all changed to electric drive, engine split cooling, and reduced internal friction loss. As a result, the overall fuel consumption is further reduced.

Overall, in terms of power, fuel consumption and even price configuration, BYD Qin PLUS has obvious advantages over joint venture models of the same level.

Moreover, as a super plug-in hybrid model, Qin PLUS can also enjoy multiple benefits such as exclusive green license plates for new energy vehicles, promotion subsidies, exemption from purchase tax, etc. Compared with dual-engine hybrids such as Toyota Corolla and Honda Lingpai, its cost-effectiveness advantage is more obvious.

It can be said that the arrival of BYD Qin PLUS DM-i has completely brought BYD's powertrain to the first-tier level in China and even the world. In the future, we will just have to wait and see what kind of results this car can achieve in the market.
