Ultra GT was met with favorable reviews from critics. Reviewing the album for Pitchfork, Jesse Jarnow wrote that the album is "anything but monochromatic, but its energy also feels occasionally constrained by its own parameters, with Carlson’s lyrics and the band's arrangements pogoing at the edge of total freedom, and perhaps total chaos."[2] In the Review for Tiny Mix Tapes, Leah B. Levinson called it "an album that is full of musical ingenuity and aural pleasures" but also felt that it was "lacking in long-term affect or cultural demarcators."[3]
