Kappa II / Smartstream 1.2 MPI-DPi (G4LF)
"The 1,197 cc four-cylinder petrol in the 2020+ i10, i20, Bayon, Picanto, Rio and Stonic. Non-turbo, chain-driven, simple. German used-car guides know of no engine problems so far; one engine guide warns the thin chain can stretch around 100,000 km. Some early-2024 cars were recalled for an EGR valve that can stall the engine. Slow but cheap to run. Not the older 1,248 cc G4LA."
G6DP 3.3 V6 TT
"Hyundai/Kia's 3.3 twin-turbo V6 (Lambda II, from 2016) with direct injection and a timing chain: 366 PS in the European Kia Stinger GT, also used in Genesis models. Strong and smooth. The one documented fault is the left turbocharger oil feed pipe, which can perish and leak oil onto hot parts; a worldwide recall (Europe 241039, US 24V-169) replaces it free of charge. Check the recall is done. Long-term data beyond that are still thin."
