The 5 Series Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS Series doesn’t offer pre-crash pretensioners.

The 5 Series Sedan has standard PostCrash iBrake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GS Series doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The 5 Series Sedan offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GS Series doesn’t offer backup collision prevention brakes.

The 5 Series Sedan offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The GS Series only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the 5 Series Sedan and the GS Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available all wheel drive and night vision systems.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 5 Series Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 82 vehicles tested by the IIHS. The GS Series has not been fully tested, yet.

The 5 Series Sedan’s corrosion warranty is 6 years longer than the GS Series’ (12 vs. 6 years).

BMW pays for scheduled maintenance on the 5 Series Sedan for 2 years and 26000 miles longer than Lexus pays for maintenance for the GS Series (3/36,000 vs. 1/10,000).

There are over 43 percent more BMW dealers than there are Lexus dealers, which makes it easier should you ever need service under the 5 Series Sedan’s warranty.

The 540i’s standard 3.0 turbo 6-cylinder hybrid produces 24 more horsepower (335 vs. 311) and 52 lbs.-ft. more torque (332 vs. 280) than the GS Series’ 3.5 DOHC V6. The M550i’s standard 4.4 turbo V8 produces 212 more horsepower (523 vs. 311) and 273 lbs.-ft. more torque (553 vs. 280) than the GS Series’ 3.5 DOHC V6.

Regenerative brakes improve the 5 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The GS Series doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 5 Series Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GS Series doesn’t offer an automatic engine start/stop system.

For better traction, the 5 Series Sedan has larger standard tires than the GS Series (245/45R18 vs. 235/45R18). The 5 Series Sedan’s optional tires are larger than the largest tires available on the GS Series (F:245/35R20 & R:275/30R20 vs. F:235/40R19 & R:265/35R19).

The 5 Series Sedan’s optional 245/35R20 front and 275/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the GS Series F Sport’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 5 Series Sedan offers optional 20-inch wheels. The GS Series’ largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 5 Series Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GS Series doesn’t offer run-flat tires.

The 5 Series Sedan 540i/M550i offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The GS Series doesn’t offer an active sway bar system.

The M550i offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lexus doesn’t offer an active suspension on the GS Series.

For a smoother ride and more stable handling, the 5 Series Sedan’s wheelbase is 4.9 inches longer than on the GS Series (117.1 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the 5 Series Sedan is 1.1 inches wider in the front and 1.1 inches wider in the rear than the track on the GS Series.

The M550i xDrive handles at .92 G’s, while the GS 350 pulls only .91 G’s of cornering force in a Motor Trend skidpad test.

The M550i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the GS 350 (24.9 seconds @ .77 average G’s vs. 26.1 seconds @ .72 average G’s).

The front grille of the 5 Series Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GS Series doesn’t offer active grille shutters.

A low lift-over trunk design makes loading and unloading the 5 Series Sedan easier. The 5 Series Sedan’s trunk lift-over height is 26.2 inches, while the GS Series’ liftover is 28 inches.

The 5 Series Sedan’s standard rear seats fold to accommodate long and bulky cargo. The GS Series doesn’t offer folding rear seats, only a ski pass-through.

To make loading groceries and cargo easier when your hands are full, the 5 Series Sedan’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS Series doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The 5 Series Sedan’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GS Series’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The 5 Series Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GS Series’ standard manually variable intermittent wipers have to be constantly adjusted.

A power rear sunshade and manual rear side window sunshades are optional in the 5 Series Sedan to help block heat and glare for the rear passengers. The GS Series doesn’t offer rear side window sunshades.

The 5 Series Sedan offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the GS Series.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 5 Series offers an optional wireless phone charging system (Qi) in the center console. The GS Series doesn’t offer wireless personal charging.

The 5 Series Sedan’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote Control Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GS Series doesn’t offer an automated parking system.
