What does 2H mean in cars?

[OAyla]

2H in cars represents the two-wheel drive high-speed gear. The 2H, 4H, and 4L on a vehicle indicate its four-wheel drive modes, showing that the model is equipped with a part-time four-wheel drive function. Here is an extended introduction: 1. Part-time four-wheel drive: A manually switchable drive mode where the driver can select between two-wheel drive or four-wheel drive by engaging or disengaging the transfer case. This is the most common drive mode in SUVs, offering the advantages of ensuring both vehicle power and off-road capability while maintaining fuel efficiency. The slight drawback is that the driver needs to assess road conditions and manually operate the drive mode. 2. Full-time four-wheel drive: The vehicle maintains four-wheel drive throughout the entire driving process. This drive mode provides better off-road and handling performance but cannot adjust torque distribution based on road conditions, resulting in higher fuel consumption and poorer economy. 3. On-demand four-wheel drive: Also known as real-time four-wheel drive, this is a technology developed in recent years. It uses a computer chip to control the switching between two-wheel and four-wheel drive. The notable feature of this system is that it inherits the advantages of both full-time and part-time four-wheel drive while compensating for their shortcomings. It can automatically identify driving conditions and switch between two-wheel and four-wheel drive modes based on changes in the driving environment.
