All i30 Fastbacks come with six airbags, driver attention alert and a lane-keep assist system to warn you when begin to drift out of your lane. The i30 also features two Isofix points in the rear for safely securing child seats. Both front seats are height-adjustable, with the driver?s seat benefitting from electrically-operated lumbar support. The multifunction steering wheel can be set for height and reach, too, though we aren't keen on the dashboard layout because there are way too many buttons. One of the primary reasons for choosing the i30 Fastback over the regular hatchback will be its larger luggage capacity. It?s not a vast difference but a high lip and relatively narrow opening do limit practicality, though you can fold the seats flat with a 60/40 split if you need to. There?s also some extra storage under the boot floor. Rear passenger space is on par with most of its competitors, but foot space for the middle occupant is restricted. Despite the sloped roof, the back door openings aren?t impinged upon and the doors open to a decent angle, which is useful when strapping little ones into their boosters or child seats.
