BMW M440i: 48V Mild-Hybrid Boost, Curved Display, 500Nm Torque – Check Details

BMW India has officially expanded its high-performance lifestyle portfolio with the launch of the M440i xDrive Convertible. Unveiled in early May 2026, this open-top tourer brings the iconic B58 straight-six engine to the Indian market in a sleek, four-seater package.
Positioned between the standard 4 Series and the track-focused M4, the M440i Convertible is aimed at enthusiasts who prioritize a “wind-in-the-hair” experience without sacrificing daily usability. We’ve analyzed the technical specifications, the new soft-top mechanics, and BMW’s future plans for the X6 M60i to bring you the ultimate breakdown.

Design & Build Quality

The M440i has transitioned back to a fabric soft-top roof, which is 40% lighter than the previous generation’s hardtop. This significantly lowers the car’s center of gravity, improving agility and cornering performance.

What’s Inside the Cockpit

Performance

The M440i features a 48V mild-hybrid system that provides an instant 11hp boost, filling in the torque gaps while the twin-scroll turbocharger spools up.

M-Specific Engineering

To handle the power, the M440i comes standard with an M Sport Differential. This electronically controlled rear-axle lock improves traction by ensuring power is sent to the wheel with the most grip during high-speed exits.

Future Portfolio (X6 M60i)

On the sidelines of the M440i launch, BMW showcased the upcoming X6 M60i xDrive, which will return to India with a 523hp 4.4L V8 engine—marking the return of the V8 to the X6 lineup since 2023.
