효율과 성능을 겸비한 3기통 1.0 터보 엔진은 최고출력 99마력과 118마력으로 나뉘며 1,500rpm부터 171Nm의 토크를 냅니다. 변속기는 7단 듀얼 클러치입니다.
Kia's 1.0-litre T-GDi (Turbocharged Gasoline Direct-injection) engine is offered in Rio for the first time and heads a three-engine line-up which shows improvements in fuel efficiency and CO2 emissions over the outgoing Rio.
The new engines showcase Kia's advanced engine technology capabilities through downsizing, turbocharging, direct fuel injection and weight reduction, and feature a number of detailed engineering solutions to minimise throttle lag – the delay between the driver pressing the accelerator and the turbocharger delivering boost – and reduce internal friction.
It joins revised versions of Kia's 1.25-litre and 1.4-litre petrol engines.
The 1.0-litre T-GDi engine is available with either 99 or 118bhp, in both cases with 171Nm of torque across a wide rev band, starting at only 1,500rpm, for effortless driveability. The engine is available with either a 5-speed or 6-speed manual gearbox and on the ‘GT-Line’ is available with a seven-speed DCT automatic. The 99bhp powered version has fuel consumption and CO2 emissions of 56.5mpg and 114g/km, while the sparkling 118bhp version is not far behind, with 55.4mpg and 117g/km. The respective 0-60mph acceleration times are 10.3 and 9.8 seconds, and both versions have a top speed of at least 116mph.
The 1.25-litre petrol engine develops an unchanged 83bhp and 122Nm of torque, and has fuel economy and CO2 emissions of 51.4mpg and as low as 125g/km. This easy-going entry-level power unit is ideally suited to urban driving, but is far from out of its depth at highway speeds. It can accelerate from 0-60mph in 12.5 seconds on the way to a top speed of 107mph.
The final option is a new-to-Rio multi-point injection petrol unit with a capacity of 1.4 litres and power and torque outputs of 98bhp and 133Nm. Economy is 49.6mpg, as with the 1.4 in the previous Rio, with CO2 emissions of 131g/km. The 0-60mph and top speed figures are 11.8 seconds and 109mph.
This engine is also available with a six-speed automatic gearbox for the convenience of drivers who spend most of their time in heavy traffic or who prefer an auto box. In this configuration, economy and CO2 emissions are improved to 45.6mpg and 143g/km (‘2’ grade) or 51.4mpg and 144g/km, while the performance figures are 0-60mph in 12.5 seconds and a top speed of 114mph.
All manual versions of the new Rio have Kia's Intelligent Stop & Go (ISG) engine stop-start system to eliminate tailpipe emissions and fuel consumption while stationary in traffic. A five-speed manual gearbox is standard with the lesser-powered T-GDi engine and the 1.25 unit, while all other manual models have six speeds.
Smoother, sharper, stronger and safer
The Rio relies on a similar suspension system to its predecessor, with independent MacPherson struts at the front and a torsion beam axle at the rear, but there has been extensive work to enhance comfort and driver enjoyment.
Much of this is due to the stiffer body shell of the latest Rio, which is made of 51 per cent advanced high-strength steel compared with 33 per cent in the outgoing car. The stiffer the body shell, the less the suspension has to compensate for flexing under load. Advanced high-strength steels also contribute towards weight reduction, as vital sections of the body construction do not need to be as thick. Kia has a goal of reducing the average weight of car bodies by five per cent by 2020, based on 2014 figures.
The Rio has more rigid front struts than its predecessor and a raised torsion beam to improve stability; revised springs and shock absorbers to improve compliance and comfort; vertical rear shock absorbers and front shock absorbers with advanced new valve technology for more consistent responses; and a repositioned power steering gearbox which results in improved feel when the steering wheel is in the straight-ahead position. The overall effect is more immediate handling responses and greater confidence for the driver.
A stiffer body shell also enhances crash safety by keeping the passenger cell intact in an accident while the front, rear and side crumple zones absorb impact energy. This is supported in the Rio by a raft of active safety and advanced driver assistance systems. Electronic Stability Control (ESC) and Vehicle Stability Management (VSM) mitigate against skids when cornering or accelerating on surfaces with uneven levels of grip, and all models apart from the entry-level grade have Forward Collision-Avoidance Assist (FCA) with Forward Collision Warning (FCW) City/Pedestrian and Lane Keep Assist System (LKAS) fitted as standard – this is an option on the Rio ‘1’. Kia's Forward Collision-Avoidance Assist system employs a long-range radar which detects other vehicles which then works alongside a camera which detects pedestrians ahead to help bring the Rio to a halt. The Lane Keep Assist System alerts the driver if the Rio is about to stray from its lane without the indicators having been activated. The system can also provide steering input to stop the vehicle straying from its lane.
A new feature – Straight Line Stability – senses any difference in applied brake pressure between the right and left of the car and intervenes to keep it straight. Another new feature is Cornering Brake Control, which delivers asymmetrical brake pressure when braking in tight curves to counter loss of traction. All versions of the Rio also have Hill-start Assist Control (HAC) to prevent the car from rolling backwards when setting off on steep inclines.
