2026 Genesis G90 Specs: Engine, Horsepower, and Performance

The 2026 Genesis G90 is built for drivers who want serious power without giving up a quiet, comfortable ride. Whether you’re merging onto I-26 or cruising through downtown Columbia, SC, the G90 pairs a twin-turbo V6 with technology that adjusts to how you drive. Below, we break down the specs that matter most, so you know exactly what you’re getting before you visit us. If you’d rather see it in person, you can contact Genesis of Columbia to set up a visit.

2026 Genesis G90 Specs at a Glance

The G90 has a 3.5-liter twin-turbo V6 available in two tunes, backed by an 8-speed automatic transmission and standard AWD across all three trims. The base 3.5T rides on an Electronically Controlled Suspension with Road Preview, while the e-Supercharger trims step up to a Multi-Chamber Air Suspension. Every G90 gets Nappa leather, real wood trim, a 12.3-inch center screen paired with a 12.3-inch digital cluster, and a five-passenger cabin. These specs add up to a sedan that handles long highway stretches and quick around-town errands equally well.

The G90’s proportions explain a lot about how it drives. It stretches 207.7 inches on a 125.2-inch wheelbase, which is what gives it that planted, unbothered feel over expansion joints on I-77, and the 0.27 coefficient of drag helps keep wind noise down at highway speed. Inside, passengers get 42.3 inches of front legroom and 37.8 in the second row, with 109.2 cubic feet of passenger volume.

Engine Options: Twin-Turbo V6 Power Explained

Genesis gives G90 buyers two versions of the same 3.5-liter twin-turbo V6, and the difference comes down to how much low-end punch you want. Genesis rates the standard engine at 375 horsepower and 391 lb-ft of torque, with the available 48V e-Supercharger version making 409 horsepower and 405 lb-ft. Genesis doesn’t publish a 0-60 time for the 2026 G90, so we won’t guess at one here. What matters more day to day is how the torque arrives: both engines make peak torque low in the rev range, so the G90 pulls without needing to wind out, whether you’re merging onto I-26 or easing away from a light downtown.

3.5L Twin-Turbo V6: Standard Performance

The standard 3.5T is the engine most G90 buyers will drive every day. With 375 hp on tap, it handles highway merges and daily commuting without feeling strained, and it pairs naturally with the suspension to keep the ride settled over rougher pavement.

3.5L Twin-Turbo V6 with 48V e-Supercharger: Available Performance

Step up to the 48V e-Supercharger and you get 409 hp and 405 lb-ft, a meaningful jump over the base engine. Genesis describes this setup as optimizing high-RPM power alongside low-end torque, which in practice means less hesitation off the line. U.S. News backs this up, noting the e-SC adds noticeably quicker throttle response, though it stops short of feeling like a true sports sedan. If you’re cross-shopping against the BMW 7 Series, Mercedes S-Class, or Audi A8, this is the engine that gives the G90 its best shot at winning the power argument.

8-Speed Automatic Transmission with Predictive Shift

Every G90 pairs its engine with an 8-speed automatic featuring shift-by-wire operation through a rotary dial and steering-wheel paddle shifters. The gearing runs from a 3.665 first gear down to a 0.556 eighth, which is what lets the G90 pull strongly off the line and then settle into quiet, low-rpm cruising on the interstate. It’s a subtle setup you notice mostly by the absence of jarring downshifts.

Intelligent Drive Modes and Chassis Technology

Genesis lets drivers reshape how the G90 feels through its Intelligent Drive Mode system, which adjusts engine response, suspension firmness, and steering weight depending on the mode selected. Kelley Blue Book’s testing captured this well, describing a tranquil Comfort mode alongside a noticeably zippier Sport setting. That range matters if you split time between relaxed highway cruising and something with more edge.

Five Intelligent Drive Modes Explained

Intelligent Drive Mode lets you switch between Comfort, Sport, Eco, Snow, and Custom settings, each changing engine response, suspension firmness, and steering weight. The difference between Comfort and Sport is immediately noticeable, which matters if you split time between relaxed highway miles and something with more edge.

Available Multi-Chamber Air Suspension

Suspension hardware splits by trim. The 3.5T uses an Electronically Controlled Suspension with Road Preview that scans the pavement ahead and adjusts damping before you reach a bump. Both e-Supercharger trims get a Multi-Chamber Air Suspension instead, which adjusts ride height and damping on the fly. The e-Supercharger trims also add rear-wheel steering, tightening the turning circle from 40.1 feet to 37.1, a real advantage in a Columbia parking deck or a tight U-turn on Farrow Road. Consumer Reports’ testing echoes this, finding the G90 composed and light on its feet despite its size.

Real-World Performance: Merging, Passing, and Highway Comfort

Specs on paper only tell part of the story. Consumer Reports found the G90 handles its size well, staying composed through maneuvers that trip up bigger sedans. U.S. News reported both engines feel capable and responsive in daily driving, with the e-SC’s quicker throttle response coming in handy for passing on two-lane highways. Around Columbia, SC, that translates to confident merges onto I-77 and a cabin that stays quiet at speed.

On fuel economy, the 3.5T is EPA-rated at 18 mpg city, 26 highway, and 21 combined, while the e-Supercharger comes in at 17/24/20. Both take premium fuel. With a 19.3-gallon tank, the base car’s highway range runs past 500 miles, which matters if you’re making the Columbia-to-Charleston run regularly. It’s also worth noting the 2025 G90 earned an IIHS Top Safety Pick award, though IIHS has not yet issued a rating specific to the 2026 model.

2026 Genesis G90 Pricing and Trim Overview

The 2026 G90 comes in three trims: the 3.5T AWD at $92,700, the 3.5T E-Supercharger AWD at $103,000, and the E-SC Prestige Black AWD at $105,750. Each carries a $1,495 destination charge on top, bringing delivered prices to roughly $94,195, $104,495, and $107,245.

In terms of value, the e-Supercharger AWD trim tends to offer the strongest feature-to-price ratio, since stepping up brings more than just the extra 34 horsepower. It adds the Multi-Chamber Air Suspension, rear-wheel steering, 21-inch wheels in place of the base 20s, a Bang & Olufsen 3D system with 26 speakers instead of 15, ventilated and power-massaging rear seats, and a rear wireless charging pad. Nappa leather, real wood trim, front massaging seats, and heated rear seats are standard on every G90. One practical trade-off worth knowing: the 3.5T comes with a spare tire, while the e-Supercharger trims carry a tire mobility kit instead, and trunk space drops from 12.0 to 10.6 cubic feet on the upper trims.
