• Diesels still the most frugal
• Petrols not far behind in the real world
• Unremarkable depreciation levels

Despite both petrol engines boasting admirable fuel economy returns, it’s the two diesels which offer the lowest running costs. Opt for the 110hp 1.6-litre and the i30 Tourer is claimed to return 74.3mpg on average, with the automatic 136hp version coming in at 65.7mpg.

Least economical is the 140hp 1.4-litre petrol at 51.4mpg, while the 120hp 1.0-litre claims 54.3mpg. Servicing costs are reasonable, with fixed-price service plans available, plus the five-year unlimited mileage warranty should take care of any unexpected repair costs. Depreciation is unremarkable and lags behind the Volkswagen Golf, increasing the total amount paid by cash customers.

No hybrid or electric models on offer, but the Hyundai i30 Tourer’s emissions levels are reasonable for a car of its size. Go for the 110hp 1.6-litre diesel if you want to produce the least CO2, the base-diesel putting out just 99g/km of CO2. This increases to 112g/km for the more powerful 136hp automatic version.

As for the petrols, the 120hp 1.0-litre unit emits a respectable 115g/km, while the 140hp 1.4-litre manages 129g/km in manual form, and 125g/km should you go for the automatic version.

• Hyundai has a strong reliability record
• Cars feel sturdy and built to last
• No recalls for the 2017 i30 Tourer yet

Hyundai i30 Tourer reliability will in all likelihood be sound, with the South Korean company building up an enviable record for solid, well-built cars.

The previous generation car had a couple of recalls relating to the steering and handbrake, but all issues were rectified and there’s no evidence to suggest the 2017 model should have any repeat problems.

If you are unlucky enough to have a breakdown, however, Hyundai’s five-year unlimited-mileage warranty should cover most issues and offer peace of mind.
