2017 Kia Rio

What's it like to drive?

First, the bad news: in a bid to meet Euro 5 emissions standards, the fourth-generation Kia Rio actually has LESS power and torque than the outgoing model. To achieve a paltry 6g/km reduction in CO2 emissions, the naturally aspirated 1.4-litre engine now puts out just 74kW and 133Nm (down from 79kW/135Nm). What's more, the Rio has grown in almost every direction and, even with weight-saving measures, it still tips the scales at a similar 1137kg-1162kg.

The inadequate power and torque manifest in tortoise-like off-the-line performance and uphill labouring, which can only be remedied (to some extent) by stamping on the go-pedal and waiting for the revs to climb. Once it's up and going, though, the Rio's drivetrain shows admirable refinement and the auto transmission is especially pleasing, making the most of the meagre thrust at its disposal.

Sluggishness aside, the new Rio has much to recommend it. The exterior styling is sharper and on-trend. The interior is just what you'd expect from the current Kia range, with attractive and easy-to-read analogue dials, a dark but not dour colour palette, and a high-res infotainment screen. Increases to interior space are also noticeable and the Rio doesn't feel small at all. Luggage space is now 325/980 litres with seats up/down, which is exceptional – much bigger than its nearest competitors and edging up towards small hatch territory.

But perhaps the most noteworthy upgrade is to sound deadening. Noise levels were once a Kia bugbear, especially among its cheaper models, but the new Rio is a genuinely quiet drive. An armrest makes its debut in this iteration, too, adding to the sense of comfort.

Two markdowns for the interior are the 'metallic finish dash fascia' (which has the least convincing metallic finish we've seen on a car at this price) and the leatherette seats on the SLi, which feel rubbery. The faux leather on the steering wheel (Si and SLi) is much nicer to touch.

The use of lightweight, high-strength steel in the chassis and body shell, combined with Kia's impressive-as-always build quality, give the Rio a tremendously solid feel. That Kia hallmark, a perfectly tuned ride, is a given. Steering and handling are geared towards city driving, though, and on tight and twisting country roads it sometimes feels mushy and on the verge of understeer. The seats are a bit shapeless, too, but not terrible for an entry-level car.

Should I buy one?

All the traits that have made the Rio a consistently popular car remain, while NVH improvements and the addition of an armrest and touchscreen infotainment system give this generation a more premium feel. Old-hat engine performance really drags it down, however, and one suspects Kia is keeping its powder dry for the rumoured release of a more powerful 1.0-litre three-cylinder turbo version later in the year. It might be best to watch and wait for now.
