2026 Acura ADX vs. 2025 Audi A4

Car and Driver says the 2026 Acura ADX, Acura's smallest SUV, is an affordable premium crossover styled after the Integra hatchback that, while sharing its underpinnings with the Honda HR-V, boasts a more powerful 190-hp turbocharged four-cylinder, though it could use more horsepower and rivals like the BMW X1 and Volvo XC40 satisfy slightly better on luxury and performance. Car and Driver says after three decades, the Audi A4 takes its final bow in 2025, with its spirit living on in the new A5 as Audi adopts even numbers for EVs and odd numbers for its final internal-combustion models, remaining a spritely sport compact sedan with an understated personality compared to the more assertive BMW 3-series, the opulent Mercedes-Benz C-Class, or the brash Alfa Romeo Giulia, with a potent turbo four-cylinder powertrain and no manual transmission offered.
