Fierce competition has driven up technological innovation and industrial upgrading in China’s new energy vehicle (NEV) sector, with auto brands ramping up investment and seeking cooperation.

“I’m dazzled by the configurations of NEVs, with large touch screens, voice control, and autopilot systems being almost staples for many,” said Zhou Ning, a resident in Hefei, East China’s Anhui Province, who is considering purchasing the family’s second car.

报道中的ramp up就是“增加”的意思。例如：

Announcement of the merger is expected to ramp up share prices over the next few days.
