Unexpected Speed Contest: Mazda CX-90 Outruns Dodge Charger R/T in Top Speed Test





Car and Driver's rigorous testing procedures have unearthed an intriguing comparison between two seemingly disparate vehicles: the 2026 Dodge Charger Sixpack R/T and the Mazda CX-90 SUV. Contrary to expectations, the Charger, a performance-oriented sedan, registers a greater curb weight and a lower governed top speed than its three-row SUV counterpart. This analysis delves into the detailed metrics that reveal how the Mazda CX-90, despite being slower in initial acceleration, ultimately surpasses the Charger in maximum velocity.
The Unveiling of Automotive Performance Nuances
In a recent series of tests conducted by Car and Driver, the 2026 Dodge Charger Sixpack R/T, equipped with a 420-horsepower engine, registered a substantial curb weight of 4921 pounds. This figure places it 25 pounds heavier than the Mazda CX-90, a three-row, eight-passenger sport utility vehicle. While the six-cylinder Charger can accelerate from 0 to 60 mph in an impressive 4.7 seconds, significantly faster than the CX-90's 6.9 seconds, its top speed is electronically limited to 125 mph. In contrast, the Mazda CX-90, powered by a 280-horsepower turbocharged 3.3-liter inline-six engine, can reach a maximum speed of 127 mph. Although the CX-90 takes a longer 29.7 seconds to hit 120 mph, it demonstrates its capability to maintain acceleration beyond the Charger's governed limit, eventually overtaking it in extended high-speed scenarios. This outcome is partially attributed to the Charger's STLA architecture, designed for both internal combustion and electric powertrains, contributing to its increased mass. The inclusion of standard all-wheel drive, wider tires, and larger wheels also adds to the Charger's considerable heft. For perspective, the all-electric Charger Daytona Scat Pack sedan tested a curb weight of 5938 pounds, exceeding that of a long-term Ram 1500 Laramie pickup by 16 pounds.
This comparative analysis underscores a fascinating distinction in automotive performance: the difference between 'quickness' and 'speed.' While the Charger excels in rapid acceleration, designed for exhilarating bursts of power, the CX-90's ability to achieve a higher sustained velocity positions it as 'faster' in a top-end context. This revelation might offer a unique bragging right to CX-90 owners who encounter Charger R/T enthusiasts, providing an interesting point of discussion on the track or at automotive gatherings. It challenges preconceived notions about vehicle performance and highlights the importance of comprehensive testing in evaluating modern automobiles.
