Derived from Kia's U2 diesel family, it develops 66kW at 4,000rpm and 220Nm of torque across a broad 1750 to 2750rpm range, giving the new Rio a flexible and lively performance, combined with great fuel economy.
The EcoDynamics package also includes low rolling resistance tyres, a drag-reducing front grille, a gearshift indicator and rear spoiler.
A smooth, six-speed manual transmission is fitted as standard.
Kia NZ's general manager, Todd McDonald, says the arrival of the diesel model provides a further boost to the Rio range, which is already one of the brand's best sellers in this market.
"Rio is going remarkably well for us in New Zealand, thanks to the desirability of the sporty design, high specification level and attractive price point. And with petrol prices set to rise again shortly, the appeal of the diesel model has just got better," he says.
Like the rest of the Rio range, the CRDi benefits from a re-engineered suspension system that is based on European specifications, with the emphasis on sporty handling and an assured ride.
The diesel also features Hill Assist Control to prevent it momentarily rolling backwards when pulling away up steep gradients.
Equipment levels within the roomy cabin are high and the standard features on the Rio CRDi include high-tech daytime running lights for increased safety, reverse warning sensors, heated/powered door mirrors, remote locking with in-built car alarm, a height-adjustable driver's seat, two-way steering column adjustment, split folding rear seats, rear luggage cover, trip computer, Bluetooth and an MP3-compatible/radio/CD audio system with USB and AUX ports.
