Coming Soon

Genesis G90 RS4 (2nd Generation)

20232026 · RS4 · sedan

Second-gen G90 is Genesis's full-size luxury flagship, with the longest wheelbase Hyundai-Kia has ever sold in the US and an interior that legitimately competes with the Lexus LS and Audi A8. US lineup: 3.5L Smartstream twin-turbo V6 (375 hp) on the short-wheelbase, and 3.5L Smartstream twin-turbo V6 with a 48V e-supercharger (415 hp) on the long-wheelbase. AWD standard on LWB, optional on SWB. Built at Ulsan in Korea.

Watch out: Brand-new platform and powertrain combination, so the long-term defect record is still forming. Early-build cars had some minor software-related complaints with the executive rear-seat package electronics. The 48V e-supercharger system is unique in the segment; aftermarket service expertise outside Genesis dealers is essentially zero.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
