Kappa 1.0 MPI / Smartstream 1.0 DPi (G3LA/G3LD/G3LG)
"The non-turbo 1.0 three-cylinder in the i10 and Picanto (2011 on; G3LA, later G3LD/G3LG Smartstream DPi), also offered with factory LPG. Simple, chain-driven, cheap to run, slow outside town. Owner data show few engine faults; watch for oil seepage or consumption and a stretched chain on hard-driven cars. Some 2024 cars were recalled for an EGR valve that can stall the engine. Not the 1.0 T-GDi."
Smartstream G3.5 (G6DU / G6DT)
"Hyundai and Kia's naturally aspirated 3.5 V6 of the Smartstream generation (from 2020): port injection (G3.5 MPi, about 272 hp) or combined port and direct injection (G3.5 GDi, about 290-300 hp) in the Kia Carnival KA4, Sorento MQ4 and K8 and the Hyundai Santa Fe TM and Staria. Timing chain and hydraulic lifters. Too new for long-term data; engine guides expect about 300,000 km. US Carnivals were recalled for fuel leaks at the fuel rail. Not the Genesis 3.5 twin-turbo (G6DS) or the older 3.3 GDi (G6DH)."
