Frequently asked questions
Which Kia Stonic engine is the most reliable?
1.4 MPI (G4LC) — Reliable verdict. The 1.4 MPI (G4LC — the naturally-aspirated, port-injected Kappa four shared with the Rio and i20) is the simple, dependable Stonic choice: no turbo, no direct-injection carbon, chain-driven and very cheap to run. It's modest on power and works a little hard in the crossover body, but mechanically it's about as low-worry as modern petrols come — exactly the engine for a buyer who wants minimal fuss and running costs. Cautions are trivial age items. The honest, bulletproof pick if you don't need the turbo's pace.
