Until now, we’ve seen the next-generation G20 BMW 3 Series wearing plenty of camouflage and placeholder head- and tail lights. The prototypes shown in these latest images from our European spy photographers still carry heavy disguise, but the lamps have been swapped out for what appear to be production-spec LED units.

The four main projectors are U-shaped and small in size, giving the car a sharp, futuristic look. The daytime running lights are discrete and positioned below the projectors, rather than forming the characteristic corona rings around them as we’re used to, so these headlights are likely entry-level units that will replace the standard halogen items on the current F30 model.

Also visible are the tail lights which, like the facelifted F30 LCI, appear to be full-LED items, with L-shaped light guides and slim brake and indicator lights. Inside, expect the G20 to come a smaller, less expensive version of the interior seen on the G30 and the G12 7 Series, like the one on the new G01 X3.

The options list should include plenty of newfangled tech, such as a 12.3-inch digital instrument cluster and a new iDrive infotainment system with a 10.2-inch touchscreen, a tile-like interface and gesture control. There will almost certainly be plenty of semi-autonomous driving features offered as well, such as active cruise control with steering and lane control assistant and lane change assist.

Under the skin, the new 3 Series will ride on Cluster Architecture (CLAR) that is expected to shave more than a few kilograms from the not-exactly-portly F30, despite an expected increase in size. All this without using carbon fibre like the G12 – instead, the G20 should make increased use of other lightweight materials such as aluminium, much like the G30 and G01.

Engine choices are expected to run the gamut of the usual three-, four- and six-cylinder turbocharged petrol and diesel engines, including the revised three- and four-pot engines announced last year. Also expected is a plug-in hybrid (like the current 330e) as well as a fully-electric variant using the same powertrain as the X3 EV coming in 2020.

The usual high-performance M3 and M4 will feature later on, powered by new S58 3.0 litre twin-turbo straight-six that will also make its way to the X3 and X4 M, with outputs set to exceed 450 hp. Expect it to be mated to an eight-speed torque converter automatic transmission rather than the current seven-speed dual-clutch unit, mirroring a similar switch BMW made on the F90 M5.
