The 2025 BMW M440i is a high-performance variant of the 4 Series coupe and convertible. It is powered by a 3.0-liter turbocharged inline-six engine that produces 382 horsepower and 369 lb-ft of torque. The M440i is available with either rear-wheel drive or all-wheel drive, and it comes standard with an eight-speed automatic transmission.
The M440i is a significant improvement over the previous-generation 440i. It is more powerful, has better handling, and is more luxurious. The M440i is also more fuel-efficient than the 440i, thanks to its new engine and transmission.
