The Mazda CX-90 is a full-size crossover SUV^[2] with three-row seating produced by the Japanese automaker Mazda.^[4][5] It is the second vehicle to use Mazda's rear- and all-wheel drive with longitudinal engine layout categorized as Large Product Group after the CX-60.^[4] The largest Mazda SUV to date, the CX-90 replaced the CX-9.^[6][7]

A version with two-row seating, while retaining the same bodywork, body length and engine options is marketed as the Mazda CX-70. The CX-70 was introduced in January 2024, featuring minor styling differences compared to the CX-90.^[8]

The CX-90 was revealed on 31 January 2023, for the North American market, while a release in the Australian and Middle Eastern markets occurred later during 2023.^[6][9] The CX-90 is available with a choice of six, seven, or eight-passenger seat configurations. The CX-70, the two-row variant with five seats, was revealed on 30 January 2024 in North America. The CX-70 differs from the CX-90 by its front and rear bumper designs, black exterior accents replacing chrome, unique wheel designs, and differing interior colour scheme options.^[10]

With the use of the rear-wheel-drive-biased large vehicle platform, the CX-90 and CX-70 are placed into the brand's internal "Large Product Group" category. According to Mazda, the CX-90 addresses many of the weaknesses of the CX-9 such as its small interior space.^[11]

The CX-90 and CX-70 are also equipped with the Kinematic Posture Control technology, a feature originally developed for the 2022 MX-5 Miata and also present in the similar CX-60. The software suppresses the vehicle's body lift during cornering to improve stability and traction, helping occupants maintain a natural posture.^[4]

The CX-9 was discontinued in North America, replaced by the CX-90 and CX-70.^[7] Like its predecessor, the CX-90 will not be sold in Japan (despite being built there) or Europe.

Available with mild hybrid and plug-in hybrid powertrain options, the CX-90 along with the CX-70 became Mazda's first production models to offer a hybrid powertrain in the North American market.^[17] There are two market dependent, mild hybrid engine options. The first is a 3.3-litre turbocharged inline-six gasoline engine marketed as the e-Skyactiv G powertrain with the M-Hybrid Boost system with two outputs, it is producing either 280 hp (284 PS; 209 kW) and 332 lb⋅ft (450 N⋅m; 45.9 kg⋅m) of torque on regular fuel or 340 hp (345 PS; 254 kW) and 369 lb⋅ft (500 N⋅m; 51.0 kg⋅m) on premium fuel. The second is an Australian only option of a 3.3-litre turbocharged inline-six diesel engine marketed as the e-Skyactiv D powertrain with the M-Hybrid Boost system producing 251 hp (254 PS; 187 kW) and 406 lb⋅ft (550 N⋅m; 56.1 kg⋅m) of torque.^[18]

The plug-in hybrid powertrain marketed as the e-Skyactiv PHEV uses a 2.5-litre four-cylinder engine with a tuned air intake and an electric motor powered by a 17.8 kWh battery, producing combined power figures of 323 hp (327 PS; 241 kW) and 369 lb⋅ft (500 N⋅m; 51.0 kg⋅m) of torque when powered by premium fuel. All-wheel-drive and an eight-speed automatic transmission are standard for all models.^[19] While the automatic transmissionis a conventional hydraulically actuated planetary gearset, it uses a single wet clutch instead of a more common torque converter to increase front passenger space in the footwell area.

The 2024 CX-90 was awarded the "Top Safety Pick +" by the Insurance Institute for Highway Safety. It received overall Good and Superior ratings on all categories except the non-turbo models, which received an Acceptable rating on headlights, as only the turbo models are offered with adaptive headlights.^[22]

Mazda USA released a series of teaser videos featuring Japanese actor Hiroyuki Sanada from January 12, 2023, to the CX-90's unveiling on January 31, 2023.^[23]
