Power That Fits Your Drive
Under the hood, the 2025 BMW 3 Series and 4 Series share the same spirited 2.0-liter BMW TwinPower Turbo engine, delivering 255 horsepower and impressive responsiveness. Both come equipped with an 8-speed Sport Automatic transmission, paddle shifters, and Launch Control — ready for spirited drives around O'Fallon.
The BMW 3 Series stands out for its integration of a 48V mild hybrid system, designed to support fuel efficiency and enhance acceleration with electric assist. This is a smart touch for those who appreciate subtle boosts in daily commuting or long-distance cruising.
The BMW 4 Series leans more into sport-driven refinement, with lightweight chassis components, precision suspension tuning, and tailored axle kinematics. This setup gives the 4 Series a road feel that's a little more tailored for enthusiasts who want to connect with the drive. Both models offer Driving Dynamics Control and an advanced suite of stability features, so you can fine-tune your ride to match your mood, whether calm and composed or sharp and athletic.
Smart Tech at Your Fingertips
Both vehicles come standard with high-quality technology, and there’s no shortage of ways to stay connected. Each model includes the BMW Curved Display, a stunning combination of a 12.3-inch digital instrument cluster and a 14.9-inch central touchscreen. BMW Operating System 8.5 allows for intuitive control by touch, voice, or iDrive controller, with access to cloud-based navigation, real-time traffic updates, and over-the-air software upgrades.
The BMW 3 Series and 4 Series also include Apple CarPlay® and Android Auto™, wireless device charging, and the BMW Intelligent Personal Assistant, which understands natural speech commands to help you navigate or adjust settings on the go.
While the tech features are nearly identical, the 4 Series adds Remote Engine Start to its lineup, ideal for warming up or cooling down the cabin before you step inside.
Interior Comfort and Custom Style
Step inside either vehicle, and you’ll find a premium interior designed with comfort and attention to detail. Both come with power front sport seats, 3-stage heated front seats, SensaTec upholstery, and Fineline Light Open Pore Fine Wood Trim. Ambient lighting adds a sophisticated touch to the cabin, while thoughtful conveniences like Advanced Vehicle & Key Memory and multi-zone climate control make day-to-day drives feel effortless.
The BMW 4 Series adds features that appeal to those who want more modern flair or added convenience, such as Perforated SensaTec upholstery, a power tailgate, and Comfort Access keyless entry. The BMW 3 Series, on the other hand, keeps it simple and classic, with a slightly more understated interior layout that prioritizes comfort and functionality.
If practicality is a priority, both vehicles offer 40/20/40 split-folding rear seats, plenty of interior storage, and one-touch power windows. No matter which model you choose, you’ll feel the craftsmanship BMW is known for.
