Engines and Performance
What engines does the 2026 BMW 3 Series offer?
The 2026 3 Series offers two engines. The 330i uses a 2.0L TwinPower Turbo 4-cylinder with 255 horsepower and 295 lb-ft of torque. The M340i uses a 3.0L M TwinPower Turbo inline 6-cylinder with 386 horsepower and 398 lb-ft of torque. Both pair with an 8-speed automatic and carry 48-volt mild-hybrid assistance.

The 330i reaches 60 mph in about 5.6 seconds. The M340i is quicker, reaching 60 mph in about 4.1 seconds in xDrive form. Both deliver the balanced, responsive handling that defines the 3 Series.
What MPG does the 2026 BMW 3 Series get?
The rear-wheel-drive 330i is EPA-estimated at 28 MPG city / 35 MPG highway / 31 MPG combined. The M340i returns an EPA-estimated 29 MPG combined. Actual mileage varies with driving conditions, equipment, and drivetrain.
Is the 2026 BMW 3 Series a hybrid?
Both 2026 engines use 48-volt mild-hybrid technology that assists the gas engine; the car never plugs in. The 330e plug-in hybrid is no longer offered in the US, so the mild-hybrid 330i and M340i are the two electrified gas choices in the lineup.
