Engine control [SKYACTIV-G 1.3, SKYACTIV-G 1.5]

• L-jetronic and D-jetronic type detectors have been combined for intake air amount detection, improving the accuracy of the intake air amount measurement.

• Electric variable valve timing control has been adopted on the intake side for improved fuel efficiency and pumping loss reduction by variably controlling the intake valve timing without any influence from the engine conditions.

• The engine coolant control valve adjusts the engine coolant control valve opening angle and supplies engine coolant to the appropriate engine coolant passage according to the changes in the engine coolant temperature. (with coolant control valve)

• Further engine warming has been promoted by blocking each water passage while the engine is cool. (with coolant control valve)

• i-stop control has been adopted for improved fuel efficiency, reduced exhaust gas emissions, and reduced idling noise. (with i-stop control)

• With the adoption of the i-ELOOP, charging efficiency during deceleration is improved. Because loss of engine force does not occur when the battery is recharged during deceleration, fuel economy is improved. (with i-ELOOP)

Engine control [SKYACTIV-D 1.5]

• By adopting boost control and attaining efficient, high air charging pressure in all ranges, low emission performance, low fuel consumption, and high torque/high response have been achieved.

• An exhaust gas recirculation (EGR) system has been adopted for cleaner exhaust emissions and improved fuel efficiency.

• i-stop control has been adopted for improved fuel efficiency, reduced exhaust gas emissions, and reduced idling noise.

Suspension

• Front suspension

― Strut-type suspension adopted

― For the front crossmember, the welded flange has been eliminated (flange-less), the cross-section expanded and the connection rigidity of the welded parts improved to achieve both rigidity and light weight.

― By adopting a 6-point rigid mount-type front crossmember, the force generated from the tires is transmitted directly, and an agile vehicle response in low-to-mid speed range has been adopted.

• Power steering

― A column assist-type Electronic Power Steering (EPS) has been adopted.

― EPS provides smooth handling from low to high speeds. This is a result of the excellent steering feel provided by the electronic control and the vehicle-speed responsive control.

― EPS does not require a power steering oil pump and generates assist force only when the steering wheel is steered. As result, engine load is lowered and fuel efficiency is improved.

― An automatic configuration and steering angle neutral position auto-learning function has been adopted, improving serviceability.
