Fuel economy

Petrol engines 42.2 - 47.1 mpg
  • Petrol line-up is reasonably fuel efficient
  • 1.0-litre T-GDi claims best fuel economy
  • But 1.4 T-GDi isn’t far behind

All i30 Fastback engines have been tested under the latest WLTP procedures, and the best performer for mpg is the 1.0-litre T-GDi, returning up to a claimed 47.1mpg (N-Line model comes in at 44.8mpg). However, the 1.4 T-GDi isn’t too far behind at 45.6mpg (N-Line models return up to 42.8mpg). Choose the DCT auto gearbox with this engine and things improve slightly to 46.3mpg (44.8mpg for the N-Line). 

The five-year warranty, roadside assistance package and annual health check you get with all Hyundai models is a nice touch for added peace of mind. 

Pick the 1.0-litre turbo and CO2 emissions range from 125-126g/km (the latter figure is for the N-Line), while the 1.4-litre turbo emits 132g/km across the line-up. Go for the DCT and emissions are lower at 124g/km (129g/km for the N-Line cars).

  • No recalls for the current i30 model
  • Hyundai has a strong reputation for reliability
  • Plus a reassuring five-year warranty

Hyundai’s reliability record is excellent, and there’s absolutely no reason to expect the i30 Fastback will be anything other than a dependable machine. All of the engine and gearbox options have been tried and tested in other products from the company and we’ve heard no horror stories to be concerned about. 

In fact, the current i30 – in any form – hasn’t suffered from any recalls so you can take comfort in this if you’re considering one.
