In July 2015, in an interview with British fashion magazinei-D, Charli XCX said that she was working on her third album and described it as "the most pop thing, and the most electronic thing" she had done. British producer Sophie has been confirmed to be involved in the album's production. In October 2015, Charli XCX released "Vroom Vroom", which was the first song released from the EP, on the Beats 1 Radio Show, then claiming it would be the first song released from her third studio album. On 23 February 2016, it was announced that Charli XCX had set up a new record label, Vroom Vroom Recordings, and that she would release an EP titled Vroom Vroom on 27 February 2016. The second song released from the EP, titled "Trophy", received its first play on Zane Lowe's Beats 1 show on that night. Charli XCX will also host her own Beats 1 show fortnightly. Charli XCX released a music video for the song "Vroom Vroom" on 22 April 2016 via Apple Music. On 27 May 2016, an autographed vinyl version of the EP was released in a limited run of 1,000 copies by Warner Music.
Critical reception
At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream critics, the album received an average score of 64, which indicates "generally favorable reviews", based on 9 reviews. Spin gave the album a favorable review, stating that, "Vroom Vroom is scintillating new ground for Charli, totally unlike anything she's ever done before, and still quintessentially her in its streamlined, indomitable turbo-pop." Tiny Mix Tapes wrote "this is pop music reinventing itself, reasserting its autonomy," describing Sophie's production as "like liquid metal or maybe the noise equivalent of non-Euclidean geometry." The Line of Best Fit wrote that the album "sounds like a kind of nihilist, amphetamine laden rebellion; A mish mash of poppy melodies, rap, trap beats and doom ridden synth which, though on paper sounds like chaos, is clearly painstakingly curated." In a negative review for Pitchfork, Laura Snapes wrote that "no one is being done any favors reducing Charli XCX to a vapid cypher, particularly as it drains her vivid personality from the work". However, in November 2019, Snapes expressed regret about her review, tweeting that she would like to "publicly disavow the nonsense" she wrote about the EP. Pretty Much Amazing wrote that "Vroom Vroom might have worked had Charli written some better hooks, or actually put some effort into her raps, or just not rapped at all."
