The song is called "Vroom Vroom", a MQ version leaked a few months ago

In January Charli went to Sweden with Rostam, MNDR, and SOPHIE who she invited out there. “We clicked and did four or five songs. One of them is called “Vroom Vroom.” I don't know if we'll put it out soon or if it'll be on my next record but my next record is gonna be the most electronic thing I've ever done.”
I kinda like it
