The Spectre has 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 Electrified G80 doesn’t offer an active sway bar system.
The front and rear suspension of the Spectre uses air springs for a smoother, controlled ride than the Electrified G80, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
The Spectre offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Genesis doesn’t offer an active suspension on the Electrified G80.
The Spectre has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Spectre’s 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 Electrified G80 doesn’t offer a load leveling suspension.
For a smoother ride and more stable handling, the Spectre’s wheelbase is 7.9 inches longer than on the Electrified G80 (126.4 inches vs. 118.5 inches).
