Will a new energy vehicle roll backward if the accelerator is pressed before releasing the handbrake during startup?

New energy vehicles will not roll backward if the accelerator is pressed before releasing the handbrake during startup. Here are the details: 1. Introduction: New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in power control and driving systems to form vehicles with advanced technical principles, new technologies, and novel structures. 2. Classification: New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline and diesel.
