8th VIN digit engine code, and on the CN7 it changes the car more than the trim badge does: ‘G’ = 2.0L MPI Nu (147 hp, SE / SEL / Limited), ‘F’ = 1.6L T-GDI Gamma II (201 hp, N Line), ‘J’ = 1.6L GDI Kappa hybrid (Hybrid Blue / Limited). All three confirmed against NHTSA vPIC pattern data. The inspection splits three ways. ‘G’ cars are port-injected, so the intake-valve carbon question that dogs GDI engines does not apply — spend the time instead verifying this exact VIN against every Hyundai KSDS campaign, because some CN7 VINs are included. ‘F’ cars pair the turbo with a 7-speed dual-clutch: drive from cold in stop-and-go and feel for low-speed shudder or hesitation on a 1-2 engagement, which is the single most-reported N Line complaint and a clutch-pack job, not a fluid change. ‘J’ cars also use a dual-clutch rather than a CVT, so the same low-speed engagement test applies, plus a scan for hybrid-system codes and confirmation the traction battery has never thrown a cell-imbalance fault. Run the full VIN at nhtsa.gov before purchase to confirm all open campaigns are closed.
