today, let’s talk about the driving quality and fuel consumption of this byd song l dm-i.

power output

enough

this car is a byd dm-i 5.0 hybrid system, equipped with a 1.5l naturally aspirated four-cylinder engine with a maximum power of 74 kw and a maximum torque of 126 nm. the whole series is equipped with a permanent magnet synchronous front-drive single motor as standard, with a maximum power of 160 kw and a maximum torque of 260 nm. our top-of-the-line model is equipped with a 26.6 kwh battery pack and a cltc range of 160 kilometers.

the power output is relatively smooth, with basically no sluggishness and no "jumping". when cruising at high speed, the engine enters a direct-connected state, and the noise of the engine starting and intervening can be felt. in addition, the new dm-i 5.0 system has lower engine power and increased compression ratio, which is fuel-efficient.

we drove normally in beijing in the summer, and in low-power hev mode, the car's fuel consumption was 6.4 liters per 100 kilometers in the past 50 kilometers, and the average speed was 27 kilometers per hour. (sharing personal car data does not constitute a purchase recommendation.)

when driving at high speed, because this car is still a single-gear hybrid, the speed can only be increased by increasing the engine speed. when cruising at 120 km/h, the instantaneous fuel consumption displayed is 7 liters/100 kilometers. (sharing personal car data does not constitute a purchase recommendation.)

in addition, the "cumulative average energy consumption" displayed by this car is still the same as before, "100km fuel consumption = total mileage fuel consumption / total mileage", "100km electricity consumption = total mileage pure electricity consumption / total mileage", and "total mileage = pure electric mileage + fuel mileage". in other words, the more pure electric mileage, the lower the average fuel consumption displayed.(the above data is the fuel consumption data we shared when we drove this car. it is for reference only and does not constitute a purchase guide or evaluation conclusion!)

driving experience

good at transport

the suspension bounce texture of this car is good, and the shock absorber damping rebound is also relatively comfortable, which is much stronger than the previous song plus. however, when encountering larger bumps, the front suspension fluctuates more than the rear suspension, and there will be a certain amount of vibration aftershocks. however, it is still more than enough to deal with paved roads and urban transportation.

the steering feel of the steering wheel is relatively average, and the suspension support is acceptable. as a city vehicle, it is competent.

although this car supports l2-level assisted driving, there is still a lot of room for improvement in actual use. if the road markings are unclear and the road conditions ahead are complex, the intelligent assisted driving will exit at any time and downgrade to "adaptive cruise control", which requires manual takeover.

steering force

on the same road section (with the same ground friction), we adjusted the tire pressure to the manufacturer's standard tire pressure, used the standard mode, and used a dynamometer to rotate the steering wheel 90 degrees at a constant speed in place, taking the maximum value.

in standard mode, the steering force of the steering wheel is 1.409 kg, which is not easy to do when turning at low speed or parking.

engine vibration

test method: after the water temperature returns to normal, turn off the air conditioner. at idle speed, use a vibration meter perpendicular to the crankshaft and place the probe in contact with the highest position in the middle of the engine metal body to measure the engine vibration acceleration value. the lower the value, the smaller the vibration.

this car is equipped with a 1.5l four-cylinder naturally aspirated engine, and the measured idle vibration value is 6.6 m/s²

engine noise

not bad

test method: the engine is fully heated, the water temperature is normal, the air conditioner is turned off, and the test is conducted at normal idling speed; the engine cover is opened, the engine hood is removed, and noise is collected at a distance of 20 cm above the engine body, and the average value is taken as the value of the engine noise outside the car (dba); inside the car, the windows are closed, the engine is running at 2000 rpm without load, and the noise meter is placed directly above the steering wheel. the average value is taken as the value of the engine noise inside the car (dba). and the comprehensive calculation is carried out with a weight of 30% inside the car and 70% outside the car.

this car is equipped with a 1.5l four-cylinder naturally aspirated engine. the idling noise outside the car reaches 70.6dba, and the engine idling noise inside the car is 33.6dba.

low beam

test method: take the front end of the headlight as the base point, 2 meters away from the vertical wall, test when the engine is in normal working condition, and use a light meter to take the maximum value within the low beam lighting range.

the headlights of this car are led light sources with a maximum illumination of 5660 lux.

paint color difference

test method: use a colorimeter to take a reference value at the center of the hood. perform comparative measurements at other locations on the vehicle body and record the location with the largest value. the number of sampling points for vehicle body testing should not be less than 100.

after testing, the maximum color difference is located at the front bumper, with a color difference of 1.13δe, which is darker and redder than the reference point. judging from the numerical value, the quality of the car's paintwork is acceptable.

summarize

very suitable for commuting to get off work!

the driving quality of this song l dm-i is better than the previous song plus dm-i, and it has indeed improved, especially the bounce quality of the suspension has been improved a lot, so it is no problem for daily transportation and is suitable for most household needs. because it is a single-speed hybrid, the speed can only be increased by increasing the engine speed when driving at high speed. therefore, the fuel consumption depends on your road conditions, environment and skills, and it is difficult to simply evaluate.

so what are the internal workmanship and materials of this byd song l dm-i? please continue to pay attention to the subsequent disassembly content!
