Positioned just below the full M3 in the facelifted (LCI) G20 3 Series range, the 2025 BMW M340i xDrive uses BMW's B58 3.0-liter single-turbo inline-six with 48-volt mild-hybrid assistance to make 386 horsepower and 398 lb-ft of torque. Drive goes through an eight-speed Steptronic torque-converter automatic to the xDrive all-wheel-drive system, and BMW quotes a 0-60 mph time of 4.1 seconds with an electronically limited 130-mph top speed. It remains the enthusiast's choice in the mainstream 3 Series lineup, blending sport-sedan pace with everyday four-door usability.
