2026 Genesis G80: 300-hp 2.5T vs 375-hp 3.5T
Market: US. Year basis: MY2026.
Market identity and 2026 changes
A 2026 Genesis G80 makes an interesting counterpoint to the industry’s growing number of crossovers: it is a full-size-feeling executive saloon with conventional petrol engines in the documented US lineup. Buyers should distinguish its current-generation facelift from the smaller G70 and electric Genesis models. The factory builder identifies multiple 2.5T and 3.5T grades, giving enough evidence for a proper model-year record without claiming that every advertised interior feature is universal.
Engines, drivetrains and certified data
The 2.5T AWD uses a 2.5-litre turbocharged four-cylinder with 300 hp and 311 lb-ft, while the 3.5T uses a twin-turbo V6 rated at 375 hp and 391 lb-ft. Both have an eight-speed automatic and AWD. Genesis lists 20 city/29 highway mpg for 2.5T and 15/24 for 3.5T. Those figures represent different US equipment and engine configurations. They should not be copied to a rear-drive export-market car or used as a direct WLTP comparison.
| Variant | Powertrain | Transmission | Drive | Manufacturer evidence | Measurement |
|---|---|---|---|---|---|
| 2.5T AWD | 2.5L turbo four-cylinder, 300 hp, 311 lb-ft | 8-speed automatic | AWD | US city highway: 20/29 mpg | US manufacturer listing |
| 3.5T Sport Prestige AWD | 3.5L twin-turbo V6, 375 hp, 391 lb-ft | 8-speed automatic | AWD | US city highway: 15/24 mpg | US manufacturer listing |
Buying strengths and trade-offs
G80 is strongest as a refined daily car for someone who values a low seating position, a conventional boot and calmer long-distance travel. Rear legroom and driving position deserve a test, particularly if a chauffeur-style role is envisaged. The V6’s stronger acceleration costs more in fuel and potentially in running-cost consumables, so buyers who mostly use congested city roads may prefer the 2.5T and invest in comfort equipment instead.
Alternatives and choosing a grade
The wide 27-inch OLED display appears in the 2026 equipment story, but ventilated seating, surround-view cameras and Nappa trim are tied to specific packages. Mercedes-Benz E-Class, BMW 5 Series and Lexus ES provide alternative approaches to ride comfort and digital interfaces. Compare real as-equipped vehicles, not brochure hero photographs. Some buyers may also prefer a simpler physical-control layout if frequent screen interaction is unwelcome.
Ownership and 2026 used-car checks
Used MY2026 G80 buyers should inspect the service trail, drivetrain, suspension and infotainment systems with qualified assistance. Check that advanced-assistance features and digital services continue to operate under the ownership transfer. Verify the original market and trim because equipment from a different model year or foreign-market G80 is not automatically compatible. No unsupported repair cost, recall scope or reliability rank is attached.
