2025 BMW 4 Series Powertrain
The 4 Series remains available in two distinct variants. The base 430i coupe and convertible have a 2.0-liter TwinPower Turbo Miller cycle four-cylinder with a reconfigured ignition system, redesigned intake ports and combustion chambers, revised camshaft control, and a mild-hybrid system to produce 255 horsepower and 295 lb-ft. of torque – same as the outgoing 430i.
Meanwhile, the M440i has a 3.0-liter turbocharged inline-six and a 48V starter generator. Unlike the 430i, the hybrid system in the M440i has resulted in a power hike. With a total system output of 386 horsepower and 398 lb-ft. of torque, the 2025 M440i has four more horses and 29 more lb-ft. of torque. The hybrid motor delivers an 11-horsepower boost when required.
Both engines receive an eight-speed automatic transmission that drives the rear wheels. BMW’s xDrive all-wheel drivetrain is available for the 430i and M440i coupe and convertible.
Fuel Economy
The official EPA numbers of the 2025 4 Series are forthcoming.
However, the 2024 BMW 430i Coupe with rear-wheel drive returns an EPA-rated 25 in the city, 34 on the highway, and 28 combined. The 2024 BMW M440i Coupe with rear-wheel drive delivers an EPA-rated 24/32 city/highway and 27 combined.
