The next-generation BMW 3 Series is due out in 2018. According to AutomobileMag, citing sources in Munich, “The next BMW 3 Series will be even better than the last 3 Series.”


The sources say the G20 will have a softer ride than the F30 3er, yet it will be sportier. So how can that be achieved? BMW engineers believe the use of adjustable suspension dampers, switchable anti-roll bars, active steering, and a torque-vectoring system that integrates with the car’s ABS and stability control, will give the G20 a more dynamic drive than its predecessor.

A longer wheelbase, wider track, lower center of gravity, and lighter curb weight should help, too.

Other goodies included in the G20 are stronger brakes, reduced-friction wheel bearings, adaptive suspension that can modulate camber on the fly, all-wheel drive with quicker torque distribution, and aluminum and carbon-fiber compound wheels.

As we reported before, the 2018 3 Series is built upon the CLAR architecture, formally known internally at BMW as “35up”.


While BMW has yet to choose the final design, the contenders are said to be quite strong. Automobile Mag says the new exterior design will bring to the market a muscular body, a sleeker greenhouse, and a sportier stance, achieved through sharper creases, harder edges, more adventurous radii, and even tighter cutlines. Our own sources say the new 3 Series’ design will be more spectacular than the current Mercedes C-Class.

Inside the cabin, the 3 Series will boast a variety of high-definition instrument graphics and a more comprehensive head-up display. A large color monitor in the center stack allows the driver to control the car functions through touches, gesture control and voice commands.

To close the gap with the competition, BMW plans to invest in better materials and higher-quality details such as carpets, rubber seals, and sill covers.


BMW will continue to upgrade their family of engines. The 2.0-liter turbo-four in the 328i should put out a healthier 260 hp, and the upgraded 3.0-liter six-cylinder in the 340i should be good for 365 hp.

The M3 and M4 will adopt electronic turbochargers and water injection to push engine output to around 500 hp. We should also see at least two plug-in hybrid variants: a 1.5-liter three-cylinder with a 60-kWh motor that can go for 30 miles of EV-only driving and a 2.0-liter four-cylinder with a 90-kWh motor good for 50 electric-only miles.

Technology & Driving Assistance

All the recent tech previewed by BMW could make its way into the G20 3 Series, including active lane-keeping assist, automatic braking, self-parking via remote control, automatic overtaking under certain conditions, and semi-autonomous driving both on the highway and in stop-and-go traffic at speeds up to 40 mph.


The four-door sedan (G20) will arrive before a Euro-only Touring model (G21, 2019) and a long-wheelbase version (G28, 2019) for the U.S. and China. The G24 3 Series GT will arrive in 2020. The 4 Series family will follow in 2020 with the G23 Coupe and G22 Convertible in 2020 (will use a softop instead of the current hardtop).

The G26 4 Series Gran Coupe will debut in 2021.
