Under the hood lies the heart of the vehicle, a setup that enthusiasts and potential buyers alike often scrutinize for its blend of power and refinement.
Technical Specifications and Output
Powering the 2018 440i is the N55B30T0, a variant of BMW’s legendary N55 engine. This 2,998cc turbocharged inline-six produces 320 horsepower and 330 lb-ft of torque, figures that were competitive within the premium compact segment. The engine utilizes a single turbocharger, Valvetronic, and Double VANOS to deliver a linear power band and responsive throttle response that defines the driving experience.

Mated to an 8-speed automatic transmission and standard rear-wheel drive, the power delivery is smooth and confident. The available xDrive all-wheel-drive system enhances traction in various weather conditions without compromising the agile handling that 3 Series drivers expect. This configuration allows the sedan to accelerate from 0 to 60 mph in approximately 5.3 seconds, making it a swift mover in both city and highway environments.
