Safety

The 7 Series has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The K900 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.

An active infrared night vision system optional on the 7 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight and even aims one of the vehicle’s headlights in the direction of the person or object. The K900 doesn’t offer a night vision system.

The 7 Series has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The K900 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the 7 Series and the K900 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, blind spot warning systems, around view monitors, rear cross-path warning, driver alert monitors and available all wheel drive.

Warranty

The 7 Series’ corrosion warranty is 7 years and unlimited miles longer than the K900’s (12/unlimited vs. 5/100,000).

BMW pays for scheduled maintenance on the 7 Series for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Kia doesn’t pay scheduled maintenance for the K900.

Reliability

J.D. Power and Associates rated the 7 Series second among large premium cars in their 2018 Initial Quality Study. The K900 isn’t in the top three in its category.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Kia vehicles. J.D. Power ranks BMW 7th in reliability, above the industry average. With 4 more problems per 100 vehicles, Kia is ranked 10th.

Engine

The 745e’s standard 3.0 turbo 6 cyl. hybrid produces 24 more horsepower (389 vs. 365) and 67 lbs.-ft. more torque (443 vs. 376) than the K900’s 3.3 turbo V6. The 750i’s standard 4.4 turbo V8 produces 158 more horsepower (523 vs. 365) and 177 lbs.-ft. more torque (553 vs. 376) than the K900’s 3.3 turbo V6. The M760i’s standard 6.6 turbo V12 produces 235 more horsepower (600 vs. 365) and 251 lbs.-ft. more torque (627 vs. 376) than the K900’s 3.3 turbo V6.

Fuel Economy and Range

On the EPA test cycle the 745e running on electricity gets better fuel mileage than the K900 (52 city/61 hwy MPGe vs. 18 city/25 hwy).

On the EPA test cycle the 745e running its gasoline engine gets better fuel mileage than the K900 (19 city/26 hwy vs. 18 city/25 hwy).

The 745e can drive on battery power alone for up to 16 miles. The K900 must run its internal combustion engine to move.

Regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The K900 doesn’t offer a regenerative braking system.

Transmission

The 7 Series’ launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The K900 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the 750i’s brake rotors are larger than those on the K900:

750i

K900

Front Rotors

15.5 inches

14.2 inches

Rear Rotors

14.5 inches

13.4 inches

The 7 Series’ standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the K900 are solid, not vented.

Tires and Wheels

The 7 Series’ optional 245/40R20 front and 275/35R20 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the K900’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the 7 Series offers optional 20-inch wheels. The K900’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 7 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The K900 doesn’t offer run-flat tires.

Suspension and Handling

The 7 Series 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 K900 doesn’t offer an active sway bar system.

The front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the K900, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The 7 Series offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Kia doesn’t offer an active suspension on the K900.

The 7 Series has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The 7 Series’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The K900 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 4.2 inches longer than on the K900 (126.4 inches vs. 122.2 inches).

Chassis

The BMW 7 Series may be more efficient, handle and accelerate better because it weighs up to about 400 pounds less than the Kia K900.

Passenger Space

The 7 Series has 4 cubic feet more passenger volume than the K900 (114 vs. 110).

The 7 Series has .2 inches more front shoulder room, .9 inches more rear headroom, 7.8 inches more rear legroom and .5 inches more rear shoulder room than the K900.

Ergonomics

The 7 Series’ 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 K900 doesn’t offer an automated parking system.

Model Availability

The 7 Series is available in both rear-wheel drive and all-wheel drive configurations. The K900 doesn’t offer a two-wheel drive configuration.
