2027 BMW 3 Series in Ontario, CA: Trims, Specs, and Performance

The 2027 BMW 3 Series is an all-new eighth generation, revealed on September 29, 2026 and built at BMW’s Dingolfing plant beginning in November 2026. The U.S. launch starts in the first quarter of 2027. The gasoline lineup opens with three models: the rear-wheel-drive 330, the all-wheel-drive 330 xDrive, and the 437-horsepower M350 xDrive. Each pairs a BMW TwinPower Turbo engine with 48-volt mild-hybrid technology and an eight-speed Steptronic automatic. A fully electric companion, the BMW i3 50 xDrive, arrives in the same quarter.

Engine Options, Horsepower, and Acceleration

BMW 330 and 330 xDrive

Both four-cylinder models share a 2.0-liter turbocharged inline-four paired with a belt-driven 48-volt starter generator, rated at 255 horsepower and 295 lb-ft of torque. Each reaches 60 mph in 5.9 seconds. The choice between them comes down to whether you want rear-wheel drive or xDrive all-wheel traction.

BMW M350 xDrive

The M350 xDrive replaces the M340i xDrive at the top of the gasoline range. Its 3.0-liter turbocharged inline-six works with a crankshaft-mounted 48-volt starter generator built into the transmission housing, which contributes up to 17 horsepower on its own. Combined output is 437 horsepower and 428 lb-ft of torque — 51 horsepower more than the 386-hp M340i it replaces — and 0–60 mph takes 3.9 seconds, or 3.6 seconds measured with a one-foot rollout.

Engine Technology and Chassis

Every gasoline engine in the lineup uses BMW TwinPower Turbo technology, the latest Valvetronic variable valve control, and the Miller combustion cycle. Switchable exhaust valves cut engine drag torque by roughly 66 percent, which lets the 48-volt system recover and reuse more energy under braking. Shift paddles are standard on every gasoline 3 Series steering wheel.

Underneath, the standard chassis combines a double-joint spring-strut front axle, a five-link rear axle, and newly developed lift-related dampers, with overall wheel diameter growing from 654 to 680 millimeters. Adaptive suspension and Adaptive M Suspension are optional and are specified together with sport steering. The M350 xDrive comes standard with Adaptive M Suspension, variable sport steering, an M Sport differential, xDrive all-wheel drive, M Sport brakes, a rear spoiler, and 19-inch bi-color Jet Black M wheels. It also introduces Drift Moment, a rear-wheel-drive setting for controlled cornering slides that arrives during 2027 as a software update.
