Regardless of its engine, regenerative brakes improve the 8 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. Lexus only offers a regenerative brake system on the LS 500h.
Regardless of its engine, the 8 Series Gran Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. Lexus only offers an automatic engine start/stop system on the LS Hybrid, and doesn’t offer a disable button.
Transmission
The 8 Series Gran Coupe’s 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 LS doesn’t offer launch control.

Tires and Wheels
For better traction and acceleration, the 8 Series Gran Coupe has larger standard rear tires than the LS (275/35R19 vs. 245/50R19). The Alpina B8 Gran Coupe’s rear tires are larger than the largest rear tires available on the LS (285/30R21 vs. 275/40R20).
The 840i Gran Coupe’s standard 245/40R19 front and 275/35R19 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 LS’ standard 50 series tires. The 8 Series Gran Coupe’s optional 245/35R20 front and 275/30R20 rear tires have a lower 35 series front and 30 series rear profile than the LS 500 F Sport’s 45 series front and 40 series rear tires.
For better ride, handling and brake cooling the Alpina B8 Gran Coupe has standard 21-inch wheels. The LS’ largest wheels are only 20-inches.
Suspension and Handling
The 8 Series Gran Coupe M550i/Alpina B8 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.
For better handling and stability, the average track (width between the wheels) on the 8 Series Gran Coupe is 1.3 inches wider in the rear than the average track on the LS.
The 840i Gran Coupe xDrive handles at .92 G’s, while the LS 500h AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.
The 840i Gran Coupe xDrive executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the LS 500h AWD (25.1 seconds @ .74 average G’s vs. 27 seconds @ .65 average G’s).
Chassis
The BMW 8 Series Gran Coupe may be more efficient, handle and accelerate better because it weighs about 250 to 500 pounds less than the Lexus LS.
The 8 Series Gran Coupe is 5.8 inches shorter than the LS, making the 8 Series Gran Coupe easier to handle, maneuver and park in tight spaces.
The front grille of the 8 Series Gran Coupe 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 doesn’t offer active grille shutters.
Passenger Space
The 8 Series Gran Coupe has 1.8 inches more front headroom and 1.1 inches more front legroom than the LS.
Cargo Capacity
The 8 Series Gran Coupe’s standard rear seats fold to accommodate long and bulky cargo. The LS doesn’t offer folding rear seats.
Ergonomics
Laser headlights, standard on the 8 Series Gran Coupe, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the LS’ LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.
Model Availability
The BMW 8 Series comes in coupe, convertible and sedan bodystyles; the Lexus LS isn’t available as a coupe or convertible.
Recommendations
The BMW 8 Series outsold the Lexus LS by almost three to one during 2023.
