At the heart of the 3 Series is a 2.0-liter BMW TwinPower Turbo inline 4-cylinder engine producing 255 horsepower, complemented by a 48V mild hybrid system. Paired with an 8-speed Sport Automatic Transmission, this luxury sedan can accelerate from 0 to 60 MPH in just 5.6 seconds. Drivers can tailor their ride using BMW’s Driving Dynamics Control, which includes selectable drive modes for sportier handling or a smoother, more relaxed drive.

The BMW 3 Series also features a double-pivot-type front suspension and a 5-link rear suspension for precise cornering and confident control. Advanced braking systems, including four-wheel ventilated discs with ABS, Dynamic Brake Control, and Cornering Brake Control, ensure stopping power is both strong and smooth. Whether navigating tight streets in Collinsville or open roads near O’Fallon, the BMW 3 Series blends performance and efficiency seamlessly.
