Camouflage hides on lot on this 3 Series, but we can still see that the nose appears to take cues from the latest 7 Series. Even through the swirling wrap, you can spot shapely headlights that flow into the long, narrow kidney grille. In profile, the sedan retains the proportions of the current model, with a longish hood and short rear deck. Around back, big, round taillights protrude outward, but these somewhat garish pieces might be development parts that don't reflect the final design.
BMW reportedly uses the codename G20 for the next-gen 3 Series and plans to make the new model wider and with a longer wheelbase to create a larger passenger compartment. Even with the dimension stretch, weight could drop thanks to lighter materials. We expect that BMW will continue to offer a vast range of powertrains, and rumors hint the future M3 might use a plug-in hybrid system to boost power and lower emissions. Expect to see the updated 3 Series debut around 2018, according to our spies.
