The new ratings apply to all variants of the Rondo and Mazda6 models, although the Clio's score covers only the three-cylinder model, with the four-cylinder models still untested.
The Kia and Mazda models are both described as having performed well in the crash tests, administered by European partner Euro NCAP.
Standard safety features with the Rondo include dual front, side chest and side curtain airbags, along with ABS, electronic brakeforce distribution (EBD) and electronic stability control (ESC). Advanced seat belt reminders are fitted to all seats, including the third row in the seven-seat variant.

ANCAP has previously mentioned that it has become almost “too easy” for carmakers to score the maximum 5-Star safety rating.
In a push to increase the standard safety feature set of future cars, ANCAP has revealed a roadmap of changes to its testing criteria.
In 2014, roof-crush strength tests will be introduced along with higher standards for pedestrian safety.
By 2017, ANCAP plans to add seatbelt reminders, emergency brake assist, top-tether anchorages for child restraints and side airbags for rear seats to the compulsory list.
"In the period 2007-2011, there was a 21% reduction in deaths on Australian roads and some of this reduction inevitably will be due to safer cars,” ANCAP CEO Nicholas Clarke said in June.
“If we are to achieve another similarly big reduction in road trauma then it is vital that Australia maintains pace with developments in new safety assist technology.”
