The Mazda CX-30 is a subcompact crossover SUV produced by Mazda. Based on the fourth-generation Mazda3, it debuted at the 2019 Geneva Motor Show, to slot in between the CX-3 and the CX-5. It went on sale in Japan on 24 October 2019,^[14][12][7] with global units being produced at Mazda's Hiroshima factory, North and South American units built in Salamanca, Guanajuato, Mexico,^[1][3][4] Thailand and initial Australian units made at the AutoAlliance Thailand plant in Rayong,^[5][15] and China-market units produced in Nanjing by Changan Mazda.^[2]

The CX-30 features lightweight construction to improve performance and economy, and is offered in either front-wheel-drive or all-wheel-drive.

According to Naohito Saga, the CX-30's program manager, the new model is targeted to drivers who are still single or are married and starting a family in the United States. Mazda chief designer Ryo Yanagisawa said that it will be more acceptable as a family car in Europe and Japan.^[7] Saga also noted that Mazda named the vehicle CX-30, to avoid confusion with the China-only CX-4.^[16][17][7]

It was launched in the Philippines on 28 November 2019,^[19] Malaysia on 15 January 2020,^[20] Indonesia on 28 January 2020,^[21][22] and Thailand on 6 March 2020.^[23][24] The 2.5 turbo model was released internationally in February 2021.^[25]

The CX-30 received positive reviews upon its release. Top Gear gave it a score of 7 out of 10, with the verdict being: "Good car, the Mazda CX-30. Handles well, looks smart and has a lovely interior."^[34] Car and Driver rated it 9.5 out of 10, commenting that "If you're shopping small SUVs, the Mazda CX-30 should be at the top of your consideration list."^[35] Edmunds.com gave it a score of 7.9 out of 10, commenting that "Admittedly, it's a niche vehicle, but it has the potential to be a 'just-right' fit for car shoppers who want a slightly roomier and nicer vehicle than an subcompact crossover SUV but don't like the greater cost of bigger models such as the CX-5 or CR-V."^[36] Alan Taylor-Jones of Autocar gave the CX-30 four out of five stars, saying: "Satisfyingly agile and blessed with a truly high quality interior, the CX-30 is a tempting choice if you don’t need vast amounts of space inside."^[37]

On the other hand, Christian Seabaugh of Motor Trend was not impressed with the CX-30, saying that "The end result is that it feels neither sporty nor luxurious. Like the brand itself, the CX-30 (alongside the more successful CX-5) finds itself stuck in the middle. Worse still, it's a disappointing effort in a competitive class."^[38] What Car? rated the CX-30 three out of five stars, commenting that "Its real strength lies in its ability to feel as luxurious as premium brands in this class at a much cheaper price. Just remember that rear space is tight and the boot isn’t anything to write home about, either."^[39]

The CX-30 won the 2020 Red Dot Design Award in the Passenger Car category,^[40][41] as well as the 2020 Autozeitung Design Trophy in the SUV category.^[42] It also received the 2019 Auto Bild Golden Steering Wheel Award in the SUV/crossover category for vehicles up to 4.4 meters in length^[43] and was named Thailand Car of the Year 2020 by the Thai Automotive Journalists Association,^[44] as well as the 2020 Editor's Choice Car of the Year by Top Gear Philippines.^[45]
