The key news here is the introduction of Kia's 48V MHEV mild hybrid engine technology, an 'EcoDynamics+' set-up which makes an appearance paired with the uprated 118bhp version of the brand's latest 'Smartstream' 1.0-litre T-Gdi petrol engine. The unit comes with a Drive Mode Select system, giving drivers the choice to customise their drive with 'Eco', 'Sport' and 'Normal' settings. This Rio EcoDynamics+ model is also one of the first models from Kia to be equipped with the brand's latest 'iMT' 'intelligent Manual Transmission' set-up. This uses a 'clutch-by-wire' system that contributes to the MHEV system's greater fuel efficiency and lower CO2 emissions, while retaining the driver engagement of a conventional manual transmission. Other conventional petrol engines are still being offered in this car - including a conventional version of the 1.0 T-Gdi unit in 99bhp form, which now gets a 6-speed manual gearbox or the option of Kia's 7-speed 7DCT auto. There's also a new version of Kia's naturally aspirated 1.25-litre pertrol engine, with innovative Dual Port Injection technology and a power output of 83bhp. Otherwise, things are much as before. If your experience of the Kia Rio extends back before the launch of this MK4 version, you'll find this current car much more engaging to drive than its predecessors. The stiffer bodyshell helps here, a structure which allowed the development team to introduce a more compliant suspension system, improving the car's compliance and comfort at all speeds, while supposedly facilitating more enjoyable, engaging handling characteristics. A repositioned power steering gearbox has also provided greater feel through the helm too.
