The second is the number of cylinders of the engine, generally 3 cylinders and 4 cylinders. Cylinder 3: A new product, which is generally considered to have many shortcomings. Not smooth enough, not suitable for long-distance running, with noise and jitter. Its advantages are fast start-up and low oil consumption. 4-cylinder: relatively common, recommended, with strong power, good ride comfort and mature technology. Many people think that cylinder 4 is the bottom line of a car.
Third, the maximum power of the engine, in KW. (1 power = 1.36 horsepower, but different units need to be converted). It is common that the higher the power, the greater the fuel consumption and the higher the upper limit speed of driving.
Fourth, the peak torque, the unit is N m, the power represents whether you run fast or not, and the torque represents the power of the car. The greater the torque, the faster the speed increases; The higher the speed, the smaller the torque. So start climbing with a low gear. At this time, the speed is low and the power is high.
Five, gearbox types, common MT, AT, CVT, DCT (don't know much, just look at the advantages and disadvantages). MT: manual gear. Everything else is automatic. AT: A better choice for gearbox. Power and smoothness are good, but the disadvantage is that it is expensive. CVT: Good ride comfort, but insufficient starting power. Suitable for urban road conditions prone to traffic jams. (Common for models within 65438+ million) DCT: Fast shift speed and good power.
Sixth, environmental protection standards. At present, the most demanding is National Six, and some new cars are still National Five, which has a great impact on first-tier cities. Buying second-hand fairies requires special attention.
Seven, summary, safety > comfort and beauty > power.
