4-2-1是pickup(适合city drive)
4-1是top speed(适合highway drive)

4-1 is for high end power and 4-2-1 is for lower end. For auto we always recommend 4-2-1 because ur engine rpm cannot reach as high as manual. It will change gear about 7k rpm automatically for most of the car. Manual is different, u can rev until 9k rpm (depends on ur car setup). When 9k rpm, a lot of exhaust gas will be generated. So, 4-1 is working good here.

这是什么意思叻？
高转是pickup？低转是top speed？
还是相反？
