340i

The 340i is a performance-oriented variant of the BMW 3 Series, used to denote a higher-output version of the model line. It emerged in the mid-2010s as a successor to the 335i in many markets and became part of BMW’s lineup that sits just above the base 3 Series models. The 340i typically features a turbocharged 3.0-liter inline-six engine, delivering around 320 horsepower and 330 pound-feet of torque in most specifications. It is paired with an eight-speed automatic transmission, with a six-speed manual version offered in some markets or earlier trims. Rear-wheel drive is standard, and all-wheel drive (xDrive) is available as an option.

Performance is characterized by strong mid-range torque and smooth, linear delivery, enabling rapid acceleration and confident highway overtaking. EPA fuel economy is typical for a turbocharged six in this class, and many markets offer adaptive suspension and other performance-oriented options to sharpen handling. The 340i commonly features modern BMW technologies, including drive mode selections, stability control systems, and a chassis tuned for a balance of ride comfort and dynamic capability.

Body styles and trim: the 340i is primarily associated with the four-door sedan body in most markets, with xDrive variants available. Within the 3 Series, the 340i sits above 328i/330i offerings and can be equipped with packages such as M Sport, Luxury Line, and various driver-assistance features. Optional equipment often includes upgraded brakes, wheels, and interior refinements.

Market position and legacy: the 340i is viewed as a refined, everyday-performance option within the 3 Series, competing with rival mid-size sport sedans from Audi and Mercedes. It is appreciated for engine character and overall polish, while some critics note the price premium relative to less powerful trims and the value proposition compared with the competition.
