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 CT5 V-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.

A passive infrared night vision system optional on the 5 Series Sedan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The CT5 V-Series doesn’t offer a night vision system.

The 5 Series Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CT5 V-Series doesn’t offer a driver alert monitor.

Both the 5 Series Sedan and the CT5 V-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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

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 CT5 V-Series has not been tested, yet.

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 CT5 V-Series’ 40 series tires.

For better ride, handling and brake cooling the 5 Series Sedan offers optional 20-inch wheels. The CT5 V-Series’ largest wheels are only 19-inches.

The 5 Series Sedan offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the CT5 V-Series; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

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 CT5 V-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. Cadillac doesn’t offer an active suspension on the CT5 V-Series.

For a smoother ride and more stable handling, the 5 Series Sedan’s wheelbase is 1.1 inches longer than on the CT5 V-Series (117.1 inches vs. 116 inches).

The BMW 5 Series Sedan may be more efficient, handle and accelerate better because it weighs up to about 200 pounds less than the Cadillac CT5 V-Series.

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 CT5 V-Series doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 540i is quieter than the CT5 V-Series:

The 5 Series Sedan has a much larger trunk than the CT5 V-Series (14 vs. 11.9 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 5 Series offers cargo security. The CT5 V-Series’ non-lockable folding seat defeats cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the 5 Series Sedan offers an optional power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The CT5 V-Series doesn’t offer a power trunk, so its trunk has to be closed manually.

Unlike the driver-only memory system in the CT5 V-Series, the 5 Series Sedan offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CT5 V-Series’ optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The 5 Series Sedan’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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 CT5 V-Series doesn’t offer a rear or rear side window sunshades.

Both the 5 Series Sedan and the CT5 V-Series offer optional heated front seats. The 5 Series Sedan also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT5 V-Series.

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 CT5 V-Series’ automatic parking system does not offer parking by remote control.
