The verdict

What's good

J.D. Power IQS score beats Mercedes E-Class — genuinely fewer first-year faults
Interior design rivals BMW 5-Series at significantly lower transaction prices
Quilted Nappa leather and ambient lighting standard at mid-trim levels
Hydraulic power steering retains road feel most electric setups lose

What's not

Genesis has fewer than 400 US dealerships — service travel can be significant

Depreciation steeper than German rivals despite superior reliability scores
20-inch wheel option transmits road imperfections more than 19s

The engine

Smartstream / Lambda III

Twin-Turbo V6

A refined, near-effortless twin-turbo six that prioritizes smooth, linear luxury-grade thrust over drama, delivering strong mid-range torque with quiet composure.

Engineered by Hyundai as the Smartstream G3.5 (Lambda III) family, introduced in 2020 to replace the older Lambda II 3.0/3.3 V6s, and shared across upmarket Hyundai, Kia and Genesis models.

It uses a dual-injection system combining direct injection with port injection, switching strategies by load to boost efficiency and help prevent intake carbon buildup.
In Genesis tune it produces around 375 hp and 391 lb-ft, propelling the G80 to 60 mph in roughly five seconds.
An integrated thermal management system helps the engine reach efficient operating temperatures faster across varied driving conditions.
