“Vehicles amazing the sensors when they rains sometimes go a little crazy and sometimes you can't move the vehicle because it senses something there so you have to shut all safety features off.”
2021 BMW X4: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2021 BMW X4 is that Active Driving Assistant becomes standard on both trims. Android Auto is also standard, but the X4 otherwise carries over without a redesign.
About the 2021 BMW X4
2nd generation (2019-2021), final year before the 2022 mid-cycle refresh.
BMW positions the X4 as a “Sports Activity Coupe,” meaning it blends compact luxury SUV practicality with a lower, more style-focused roofline and a sportier driving feel than the boxier X3. The draw is not maximum cargo space; it is the combination of standard all-wheel drive, a driver-focused cabin, strong road manners, and a more expressive coupe-SUV shape for buyers who want utility without giving up BMW’s performance character.
The xDrive30i is the everyday version, with a 248-hp turbocharged four-cylinder engine, all-wheel drive, a navigation touchscreen, and a panoramic moonroof. The M40i is the performance-focused model, pairing a 382-hp turbocharged six-cylinder engine with sharper suspension, stronger brakes, and more aggressive exterior trim.
