2026 Genesis G90 3.5T E-SC: Kirkland Buyers Guide
Quick Answer: 2026 Genesis G90 3.5T E-SC
The 3.5T E-SC costs $103,000 MSRP ($104,495 with the $1,495 destination charge), about $10,300 more than the base 3.5T. The money buys a 48-volt electric supercharger on the same twin-turbo V6 (409 hp and 405 lb-ft, up from 375 and 391), a multi-chamber air suspension, standard rear-wheel steering that tightens the turning circle to 37.1 feet, ventilated and massaging rear seats, an upgraded Bang & Olufsen sound system, and self-opening power doors. The EPA rates it at 17 city, 24 highway, and 20 combined. It is the trim built for the person sitting behind the driver.
What the electric supercharger actually does
Turbochargers are brilliant once they are spinning and slightly lazy before that. The E-SC system fixes the lazy part with a small electric supercharger, powered by a 48-volt mild-hybrid system, that supplies air immediately while the turbos catch up. In daily terms you get a firmer response at low speed, which is the range you actually use in Kirkland traffic, and more punch from 409 hp at the top end. The same 3.5-liter V6 and 8-speed automatic carry over, and all-wheel drive stays standard. The tradeoff is a point or so of fuel economy and about 300 pounds of added weight from the hybrid hardware and air suspension.
A different kind of ride
The multi-chamber air suspension replaces the base trim's adaptive setup. Air springs give the car a more controlled, cushioned ride over broken pavement, a genuine help on roads that go through a Pacific Northwest winter of rain and the occasional freeze. Rear-wheel steering is the other piece of the chassis story: at low speeds the rear wheels turn slightly opposite the fronts, so a full-size sedan can pivot into a tight Totem Lake parking garage ramp more like a midsize one. The turning circle drops from 40.1 feet to 37.1.
The rear seat is the reason this trim exists
Where the base car massages the front seats, the E-SC extends ventilation and massage to the rear bench. Genesis describes its ergonomic seats as having four massage modes and ten air pockets. Add the 8-inch armrest display for climate and seat settings, the Mood Curator feature that links ambient lighting, massage, and scent, and a Bang & Olufsen audio system that is a clear step up from the base trim's Lexicon setup, and you have a cabin designed for being chauffeured or for the long trip to Eastern Washington. The exact speaker configuration can vary, so ask your sales consultant to confirm what is on the car in front of you.
Is the step up worth about $10,300?
If you drive yourself almost everywhere, the base 3.5T already has the standard Nappa leather, front massage, and safety suite, and the extra money may be better kept. If the car regularly carries passengers in back, or you value the tighter turning circle and the more controlled ride, the E-SC is the trim that justifies the flagship label. Peter P., who bought a Genesis from the Kirkland store entirely by web and phone, described the process this way: "No pressure, no hard sell. Just straightforward, supportive information that helped me feel confident in my decision." That is the kind of conversation worth having before a purchase at this price.
The 3.5T guide shows what you keep at the lower price, and the Prestige Black guide covers the all-black version of this same car.
Frequently asked questions
What does E-SC mean on the Genesis G90?
E-SC stands for electric supercharger. It is a 48-volt electric compressor that works alongside the two turbochargers on the 3.5-liter V6 to reduce lag and raise output to 409 hp and 405 lb-ft.
How much is the 2026 Genesis G90 3.5T E-SC?
The E-SC has an MSRP of $103,000, which becomes $104,495 with the $1,495 destination charge. Taxes, title, and registration are additional.
Does the G90 E-SC have rear-wheel steering?
Yes. Rear-wheel steering is standard on both E-SC trims and reduces the turning circle to 37.1 feet from the base car's 40.1 feet.
Is the G90 E-SC a hybrid?
It is a mild hybrid, not a plug-in. The 48-volt system powers the electric supercharger and does not provide electric-only driving, so there is no charging and the car runs on premium gasoline.
What is the fuel economy of the 2026 G90 E-SC?
The EPA estimate is 17 mpg city, 24 highway, and 20 combined.
