Not only is the 2017 Genesis G90 poised to replace the Hyundai Equus sedan, but it also has the responsibility of setting expectations for the newly created Genesis brand. Accordingly, the model introduces Hyundai's first twin-turbo engine and offers plenty of convenience and safety features. Despite these changes, the model still has vestiges from the current Hyundai lineup.

Like its predecessor, the 2017 G90 offers a 5.0-liter V-8 engine that produces 420 hp and 383 lb-ft of torque. But the model also brings along a new 3.3-liter, twin-turbo V-6 that delivers 365 hp and 376 lb-ft. Each powertrain comes paired to an eight-speed automatic transmission, which Hyundai says is 18 pounds lighter than before. Rear-wheel drive is standard, but optional all-wheel drive offers active torque control, which can direct up to 40 percent of torque to the front axle in snow or ice or transfer torque to the rear wheels for spirited driving.

Hyundai says it has refined ride, handling, and steering characteristics on the G90 while adding more insulation to the rear glass for better noise control. A new feature called Genesis Adaptive Control Suspension promises better body control, and larger rotors are intended to improve brake performance.

The Genesis G90 borrows many of the same styling cues from the revamped Genesis sedan, including a familiar grille and hood design. Nineteen-inch wheels and chrome surrounds the doors and bottom of the rear bumper finish off the bold look. Compared to its predecessor, the Equus, the Genesis G90 is just 1.8 inches longer but has a 4.5-inch longer wheelbase that may provide customers with extra wiggle room inside.

The G90 comes available in tame exterior colors, including shades of white, black, brown, silver, and gray. Fortunately, the interior looks a bit more brash thanks to eye-popping selections of genuine wood as well as a Nappa-leather-stitched instrument panel. The gearshift area has been redesigned and appears to take up less space, sloping upward on the center console.

Other goodies to look for in the lineup include a 12.3-inch display screen, a head-up display, a 22-way power driver seat, Lexicon sound system with 17 speakers, and a rear entertainment system with 9.2-inch dual monitors (available on V-8 models). In the safety realm, the model features automatic braking with pedestrian detection, lane keep assist, smart cruise control, and blind-spot detection.

The Genesis G90 heads to the U.S. market as well as China, Russia, and the Middle East. After the flagship comes out, Genesis will roll out five additional models within the next five years.
