The BMW 3 Series by the German pioneer automaker BMW is a compact and executive car since1975. The BMW 3 series has been produced in six generations with different body style and has been the successor to the BMW New Class. The automaker is now ready to unleash the seventh generation of BMW 3 series. The seventh generation of BMW 3 series is scheduled to be launched in 2020.

First impression
The 2020, seventh generation of BMW 3 series will have significant changes than its previous versions, as the new generation of BMW 3 series will be safer and more fuel efficient with reduced Co2 emissions. The vehicle will also be more frugal. The Eco-friendly vehicle is expected to make its full impact with the fuel efficient technology and user friendly approach as it falls into the BMW’s high volume product category.
The powertrain
The 2020 seventh generation of BMW 3 series will have a three cylinder engine. The petrol engines are cost effective to build and the cost will be diverted towards the building of the hybrid system for the vehicle. The self ignition running mode is under testing by BMW along with the multi point laser spark plug and combined injector, which is also under consideration. The most emphasized aspect of 2020 BMW 3 series is the target of Co2 emission to be dropped from 80g/km to 70 g/km. The engine will be encapsulated and floorplan suggests that the suspension arms of the engine will be in aero friendly shape and will also have a full length undertray running through the vehicle to reduce the aerodynamic drag.
There will be laser sensors to guide through narrow pathways and detect other vehicles and pedestrians on the road. There will be low drag brakes with the intelligent predication, if the diver is about to brake. This is unlike the conventional brake pads that waste energy while dragging on the discs. To reduce the drag, the inside and around the wheels will also be engineered. There will be a boundary layer created by channeling the air across the face of the wheel through the use of scoop to reduce the turbulence.
The automatic nine speed gear box of the 2020 BMW 3 series will also have a sailing mode, which will work with the 3D satellite navigation of the vehicle and will switch off the engine and put transmission into the neutral or sailing mode on the downward slopes to save energy. The battery pack will fit into the rear of the seventh generation BMW 3 series for 2020 and later there will also be a hybrid plug-in version. The suspension of the seventh generation BMW 3 series will be height adjustable to improve the fuel economy and reduce aero drag.
The exterior & Interior
BMW’s production experience of carbon fiber-reinforced plastics will be quite advanced by 2020, so there’s a good chance of carbon fiber body panels, door trims, seat frames and dashboard supports. For 2020 BMW 3 series, the head up displays will be more sophisticated and equipped with layers of information with the 3D satellite navigation for the direction, alert projection into the eye line of the diver and the radio stations. There will be laser headlamps for the seventh generation BMW 3 series, that will be 100 times smaller and as efficient as LEDs, while providing 1000 times more brightness than the current headlamps. The door handles will also be replaced by the simple hollow door handles with touch sensors and the key proximity.
What’s new
The seventh generation of the BMW 3 series for 2020 will have a three-cylinder turbodiesel engine with electric motor assist, which the sixth generation of the vehicle didn’t employ. There will be aerodynamic wheel housings to reduce drag, which was a major problem in previous versions wasting energy. The new generation aims to be lighter than its predecessors to reduce Co2 emission. The structure of the new generation will be optimized to fit the small or large battery in the rear and the vehicle will be high tech with touch sensor handles and sailing mode in the gearbox. Fuel efficiency is the focal point BMW 3 series for 2020 will be designed around.
What’s refreshing?
The most refreshing aspect of the seventh generation BMW 3 series for 2020 is that it will be more frugal and will be with better fuel economy. The low drag brakes and aerodynamic wheel housing will reduce the aero drag and save energy. Lighter than the previous versions, the seventh generation is targeting to reduce the Co2 emission to 77g/km with this engine and ultimately 70g/km by 2025, while the other car makers are still moving towards the 95g/km.
