Peter Debruge of Variety gave the film a positive review, saying "Co-writer/director David Soren's story offers little that even the average 6-year-old couldn't imagine, though the film's considerable charm comes through via its characters and sense of humor." Chris Nashawaty of Entertainment Weekly gave the film a B, saying "While there's no denying that the film is a harmless, wholesome, and heart-warming ride crafted with polish and skill, it's also so predictable that you'll see every twist in the story driving down Fifth Avenue." Bill Goodykoontz of The Arizona Republic gave the film three out of five stars, saying "There's certainly no harm in seeing 'Turbo.' Competent, pretty funny in places, awfully nice to look at, that sort of thing. There's just not a lot of excitement, though." Rafer Guzman of Newsday gave the film two-and-a-half stars out of four, saying "Turbo has just enough heart to make it to the winner's circle." Claudia Puig of USA Today gave the film two-and-a-half stars out of four, saying "This good-natured but generic animated tale of a puny garden snail with huge dreams has some appealing characters, a few laughs and then devolves into a predictable Tortoise and the Hare spinoff."
A. O. Scott of The New York Times gave the film a mixed review, saying "Even in the absence of originality, there is fun to be had, thanks to some loopy, clever jokes and a lively celebrity voice cast." Betsy Sharkey of the Los Angeles Times gave the film three-and-a-half stars out of five, saying "Honestly, they pretty much had me at racing snails." Linda Barnard of the Toronto Star gave the film two out of four stars, saying "Turbo's colourful trek to product placement-littered Indianapolis is as rote as it gets, but little viewers won't care about predictability." David Hiltbrand of The Philadelphia Inquirer gave the film two out of four stars, saying "Let's face it: Kids aren't a very demanding audience. If there's color, movement, and a high quotient of silliness, they're happy." Peter Hartlaub of the San Francisco Chronicle gave the film a negative review, saying "After the originality of the hero, the filmmakers borrow too heavily from other movies; the similarities to Ratatouille and Cars are almost distracting." Laremy Legel of Film.com gave the film an 8.5 out of 10, saying "Turbo is the sort of film that should work extremely well for folks who are interested in it. It lives up to expectations, even often exceeding them, though it's a shame it's unlikely to find much of a cross-over audience."
Colin Covert of the Star Tribune gave the film three out of four stars, saying "Turbo isn't a perfect cartoon, but it's so likable that, like its humble hero, you have to root for it." Moira MacDonald of The Seattle Times gave the film three out of four stars, saying "Ultimately, Turbo nicely lives up to its diminutive hero's credo of, "No dream is too big, and no dreamer too small"—a pleasant thought, for people of all sizes." Jen Chaney of The Washington Post gave the film two-and-a-half stars out of four, saying "Turbo is a derivative but nevertheless good-hearted movie that's peppered with enough clever touches to engage adults as well as moviegoers of the smaller, squirmier variety." Joe Neumaier of New York Daily News gave the film three out of five stars, saying "Families who have already raced to Monsters University and Despicable Me 2 will find Turbo an acceptable third-place finisher. A sort of escargot-meets-Cars adventure, it has some sharp vocal turns and remains fun even when its inventiveness runs out of gas." Tom Russo of The Boston Globe gave the film two-and-a-half stars out of four, saying "While Disney seems to actively court entertainment headlines every time it gives us a new princess of color, here there's no fuss, just a fully realized cartoon world that happens to be made up of the places and diverse faces found around an urban strip mall."
Todd McCarthy of The Hollywood Reporter called the film "An attractively designed but narratively challenged, one-note film." David Fear of Time Out gave the film two out of five stars, saying "All Turbo does is give Reynolds, Paul Giamatti, Samuel L. Jackson and Snoop Dogg the easiest paychecks they'll ever make, and its corporate overlords the chance to sell a few toys." Nell Minow of the Chicago Sun-Times gave the film a B+, saying "The movie gets a bit slow, with too much time spent on the human characters, who are dreary and underwritten, compared to the big dreams of the little snail. But the film picks up when the racing snails come back onscreen, thanks to the adorable character design, with expressive use of those googly eyes, and especially to the voice talent." A. A. Dowd of The A.V. Club gave the film a B−, saying "For all its chronic familiarity, the movie has its minor pleasures, many of them visual. Though at this point it's basically a given that a new studio-animated movie will look good, Turbo often looks downright exceptional." R. Kurt Osenlund of Slant Magazine gave the film two-and-a-half stars out of four, saying "As a film about social issues, and simply being yourself, it's commendably progressive, going so far as serving as a kind of coming-out story."
