The Spring Festival is approaching, and workers have to face the problem of returning home, such as the immigration city of Shenzhen. In the past, it was necessary to drive five or six hours from Shenzhen to Ganzhou, Jiangxi, but now the Ganzhou-Shenzhen high-speed railway is open, which only takes two and a half hours.
Regarding whether it is better to take the high-speed train or drive, Porridge and Jiahao began to argue. Porridge insists that high-speed rail is more worry-free and saves money, and Jiahao believes that going home usually drags the family with the mouth, and it will be more convenient to drive at this time. Especially for a CAR like BYD Tang DM-i, even if it is in a state of power loss, the fuel consumption is still 5.
The operating logic of BYD's DM-i super hybrid system is based on electricity and oil as the auxiliary method, and there are four power output modes of pure electricity, series, parallel and direct drive. Even in the current state of power loss, the engine not only acts as a "generator", when the vehicle speed reaches 55km/h, the engine can participate in direct drive, coupled with the 1.5T Xiaoyun engine equipped with Tang DM-i, the thermal efficiency of the 1.5T Xiaoyun engine is 40%, ensuring the fuel economy of high-speed road conditions.
Can Tang DM-i save high-speed rail? Porridge and Jiahao will make a comparison this time, respectively, in the way of self-driving and high-speed rail, from Shenzhen to Ganzhou, to see what adventures will be on the journey.
