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 LS Series doesn’t offer backup collision prevention brakes.

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 LS Series doesn’t offer a night vision system.

The 7 Series offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The LS 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.

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 LS Series doesn’t offer a driver alert monitor.

Both the 7 Series and the LS 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, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

Warranty Comparison

The 7 Series’ corrosion warranty is 6 years longer than the LS Series’ (12 vs. 6 years).

BMW pays for scheduled maintenance on the 7 Series for 3 years and 40,000 miles longer than Lexus pays for maintenance for the LS Series (4/50,000 vs. 1/10,000).

There are over 77 percent more BMW dealers than there are Lexus dealers, which makes it much easier should you ever need service under the 7 Series’ warranty.

Reliability Comparison

The battery on the 7 Series is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the 7 Series’ battery 20 to 30 degrees cooler, its life is increased by years. The LS Series’ battery is in the hot engine compartment.

J.D. Power and Associates’ 2015 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks BMW 6th in initial quality, above the industry average. With 5 more problems per 100 vehicles, Lexus is ranked 9th.

Fuel Economy and Range Comparison

On the EPA test cycle the 740i RWD gets better fuel mileage than the LS 460 RWD (21 city/29 hwy vs. 16 city/24 hwy).

Regardless of its engine, regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. Lexus only offers a regenerative brake system on the LS Series Hybrid.

Regardless of its engine, the 7 Series’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Lexus only offers an automatic engine start/stop system on the LS Series Hybrid.

Brakes and Stopping Comparison

Tires and Wheels Comparison

For better traction, the 7 Series has larger tires than the LS Series (245/50R18 vs. 235/50R18).

For better ride, handling and brake cooling the 7 Series offers optional 21-inch wheels. The LS 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 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 LS Series doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 7 Series has standard front and rear gas-charged shocks for better control over choppy roads. The LS Series’ suspension doesn’t offer gas-charged shocks.

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 LS Series 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 LS Series, 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. Lexus doesn’t offer an active suspension on the LS Series.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 4.7 inches longer than on the LS Series LWB (126.4 inches vs. 121.7 inches).

For better handling and stability, the track (width between the wheels) on the 7 Series is 1.4 inches wider in the rear than the average track on the LS Series.

The 750i xDrive handles at .88 G’s, while the LS 600h L AWD pulls only .75 G’s of cornering force in a Car and Driver skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the LS 600h L AWD (25.4 seconds @ .75 average G’s vs. 27.5 seconds @ .65 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 LS Series doesn’t offer active grille shutters.

As tested by Car and Driver while under full throttle, the interior of the 750i xDrive is quieter than the LS 460 L AWD (72 vs. 73 dB).

Passenger Space Comparison

The 7 Series has 2.8 inches more front headroom, .7 inches more front shoulder room, .9 inches more rear headroom, 8.6 inches more rear legroom and .8 inches more rear shoulder room than the LS Series.

Cargo Capacity Comparison

To make loading groceries and cargo easier when your hands are full, the 7 Series’ trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The LS Series doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

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 LS Series doesn’t offer a remote starting system.

The 7 Series offers an optional heads-up display which projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The LS Series doesn’t offer a heads-up display.

The power windows standard on both the 7 Series and the LS Series have locks to prevent small children from operating them. When the lock on the 7 Series is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The LS Series prevents the driver from operating the other windows just as it does the other passengers.

The 7 Series’ power mirror controls are mounted on the armrest for easy access. The LS Series’ power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

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 LS Series doesn’t offer an automated parking system.
