2021's Genesis X concept brought back something that has become nearly extinct in the current automotive landscape — the large, good-looking GT coupe. Genesis has further refined the initial X concept into the X Speedium, named after the Speedium racetrack in South Korea. The X Speedium fills in the X's grille in a nod to its electric powertrain and extends the roofline rearward. This adds more head and legroom for rear passengers but gives the car a look more akin to an ungainly shooting brake instead of a classic big two-door in the mold of the Mercedes S-Class coupe. Genesis hasn't announced any production plans for either version of the X.
