Design of the all-new sedan leaked a day before its global launch in Paris.
The seventh-generation BMW 3 Series has been leaked via an online configurator that went live a little ahead of schedule.
These computer-generated images show the car in 330i M Sport (blue) and M340i trims (black). For the first time they also show us the car's notched headlight design, which, to our eyes, recalls the fourth-generation (E46) model.
As we've seen in earlier teasers, the new 3 Series has fused together the two halves of its kidney grille, and has a new angular take on the Hofmeister kink.
The company's Laserlight headlamp system will be available on some models, while at the rear the 3 Series has the model line's slimmest tail-lights to date, with a prominent L-shaped brake light band, while the indicators and reversing lights live in a heavily tinted section.
As you'd expect, the cabin isn't radical and fits entirely within the company's latest design theme. There's a free-standing high-resolution infotainment screen mounted above a compact set of vents and the air conditioning controls.
A metallic frame separates the ventilation system from the audio system. The centre tunnel is remarkable only because it employs an electronic handbrake, and, on some models, is missing a gear shift lever.
Ahead of the driver is a multi-function three-spoke steering wheel, and, at least for high-spec variants, a configurable fully-digital instrumentation screen running the new BMW OS7.0 software.
The new 3 Series is expected to be powered by a range of turbocharged petrol and diesel engines, including the 225kW/450Nm turbocharged 2.0-litre four-cylinder from the X2 M35i.
Full details about the new 3 Series are expected to be released when the car is officially unveiled on the morning of Tuesday, October 2, Central European time.
