Safety Comparison

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The K900 doesn’t offer backup collision prevention brakes.

The 7 Series offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The K900 doesn’t offer all-wheel drive.

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. The K900 doesn’t offer a night vision system.

The 7 Series’ 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 K900 doesn’t offer a driver alert monitor.

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, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

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 1 year and 12500 miles longer than Kia pays for maintenance for the K900 (4/50,000 vs. 3/37500).

Reliability Comparison

J.D. Power and Associates’ 2015 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 18th in reliability, above the industry average. With 12 more problems per 100 vehicles, Kia is ranked 20th.

Fuel Economy and Range Comparison

On the EPA test cycle the 740i RWD gets better fuel mileage than the K900 V8 (21 city/29 hwy vs. 15 city/23 hwy).

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.

In heavy traffic or at stoplights the 7 Series’ 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 K900 doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

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

12.4 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.

The 7 Series stops much shorter than the K900:

Tires and Wheels Comparison

For better ride, handling and brake cooling the 7 Series offers optional 21-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 Comparison

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 driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The K900’s suspension doesn’t offer adjustable shock absorbers.

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 6.5 inches longer than on the K900 (126.4 inches vs. 119.9 inches).

The 750i xDrive handles at .88 G’s, while the K900 V8 Luxury pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver 2.9 seconds quicker than the K900 V8 Luxury (25.4 seconds @ .75 average G’s vs. 28.3 seconds @ .61 average G’s).

Chassis Comparison

The front grille of the 7 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The K900 doesn’t offer active grille shutters.

Passenger Space Comparison

The 7 Series has .6 inches more front headroom, .1 inches more front shoulder room, 1.3 inches more rear headroom, 6.2 inches more rear legroom and .5 inches more rear shoulder room than the K900.

Ergonomics Comparison

The 7 Series offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The K900 doesn’t offer a remote starting system.

Unlike the driver-only memory system in the K900, the 7 Series has standard driver and 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.

If the windows are left down on the 7 Series the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the K900 can only operate the windows from inside the vehicle, with the ignition on.

While driving with high beams on, sensitive light sensors standard on the 7 Series detect other vehicles which could be blinded and automatically switch to low beams. The K900 doesn’t offer automatic dimming high beams.

The 7 Series’ optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The K900 doesn’t offer an automated parking system.
