i30
Overview
The GD was the i30 that made Hyundai a genuine mainstream small-car player in Australia, locally tuned by Hyundai's Australian ride-and-handling team and sold in huge numbers as Active, Active X, Elite, Premium and the sporty SR. Sold as a 5-door hatch and a Tourer wagon, all front-wheel drive. The bread-and-butter engine is the 1.8L Nu MPi petrol - simple, port-injected and the safest used buy. Above it sat the 2.0L Nu GDi (direct injection, SR-flavoured) and below it the 1.6L Gamma GDi. A 1.6L CRDi turbo-diesel (the well-travelled D4FB) suited high-km commuters but brings the usual small-diesel DPF/EGR caveats on short city trips. The Series II facelift (mid-2015) added the genuine hot-hatch 1.6L T-GDi turbo SR with 150kW. Generally a reliable, cheap-to-run used car with a strong dealer network and (originally) a 5-year warranty; the things to watch are GDi carbon/oil-consumption on the direct-injection petrols, DPF clogging on city-bound diesels, and the broader Hyundai/Kia GDi engine class-action context - so always check the VIN against outstanding recalls.
Engines & variants
1.6L Gamma GDi petrol
Pros
- Frugal and cheap to run
- Timing chain (no belt interval)
- Light and willing in town
- Cheap, plentiful and easy to insure
Cons
- Direct injection means intake-valve carbon over time
- Modest torque - feels flat fully loaded or on hills
- Less common in AU than the 1.8 (more often the diesel's petrol sibling spec)
Known problems
1.8L Nu MPi petrol
Pros
- The safest used i30 buy - simple port injection, no GDi carbon issue
- Timing chain, no belt interval
- By far the most common AU GD engine - cheap parts and easy to find
- Reliable, undemanding daily driver
Cons
- Unexciting performance - adequate, not quick
- Some examples report higher-than-expected oil use
- Old 6AT can feel hesitant vs modern rivals
Known problems
2.0L Nu GDi petrol
Pros
- Noticeably more urgent than the 1.6/1.8
- Timing chain, no belt interval
- Found in sportier SR-flavoured trims
- Still cheap to run for the performance
Cons
- Direct-injection carbon build-up like the 1.6 GDi
- Reports of oil consumption on some Nu engines
- Note: this is the Nu 2.0 - NOT the larger 2.4L Theta II that carried the bearing recall - but check VIN against all recalls/coverage
- Thirstier than the 1.8 if driven hard
Known problems
1.6L CRDi turbo-diesel
Pros
- Excellent economy and effortless mid-range torque for commuting
- Long highway range, relaxed cruiser
- The well-proven D4FB - capable of 250,000km+ with care
- Good resale among diesel-keen buyers
Cons
- DPF clogs on short city-only trips that never reach regen temperature
- EGR soot build-up and intake fouling over time
- Cam belt (not chain) - has a replacement interval/cost
- Common-rail injectors are expensive if they fail
Known problems
1.6L Gamma T-GDi turbo (SR)
Pros
- Genuine warm/hot hatch - 150kW, strong low-down boost
- Runs happily on 91 RON, still frugal
- Timing chain, no belt interval
- Fun and locally tuned chassis - the enthusiast pick of the GD range
Cons
- Turbo direct-injection - intake carbon and harder life on internals
- Optional 7-speed DCT can show low-speed shudder/clutch wear
- Needs good oil discipline given turbo + GDi
- Higher tyre/brake wear if driven hard
