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". 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.
