Developed to strive for the utmost energy efficiency without compromising driving performance, IONIQ’s powertrain option represents a unique and uncompromising statement towards a cleaner mobility.
Breaking through hybrid stereotypes with IONIQ Hybrid & Plug-in
The IONIQ Hybrid and IONIQ Plug-in both feature the new Kappa 1.6 GDI, direct injection petrol, four-cylinder engine with a class-leading thermal efficiency of 40 per cent delivering 105 PS and 147 Nm of torque. The engine has been tailored to the hybrid application and is combined with the direct responding, smooth shifting six-speed double clutch transmission – differentiating the IONIQ from its competitors with a more dynamic driving experience. The mated electric motor enables pure electric driving and delivers instant torque as the chassis with rear multi-link suspension greatly enhances driving dynamics.
The IONIQ Hybrid’s electric motor delivers 32 kW (43.5 PS) with maximum torque of 170 Nm, powered by a lithium-ion-polymer battery with 1.56 kWh capacity positioned under the rear seats. In combination with the 1.6-GDI engine IONIQ Hybrid offers a system output of 103.6 kW (141 PS) rpm and up to 265 Nm of torque accelerating to a top speed of up to 185 km/h with targeted CO2 emissions as low as 79 g/km or lower (combined). The electric motor enables the IONIQ Hybrid to operate in pure electric mode at speeds up to 120 km/h.
Drivers choosing the IONIQ Plug-in can safely rely on 50 kilometres of estimated pure electric driving range powered by the potent 8.9 kWh lithium-ion polymer battery. The 45kW (61 PS) electric motor together with the 1.6 GDI four-cylinder Kappa engine offer targeted CO2 emissions as low as 32 g.
Six-speed dual-clutch transmission – responsiveness guaranteed
The IONIQ Hybrid and IONIQ Plug-in both feature a six-speed dual-clutch transmission (6DCT), which boasts best-in-class transfer efficiency by the use of low-friction bearings and low-viscosity transmission oil. They therefore achieve a unique mix of driving performance and fuel efficiency. Intelligently set gear ratios combined with a clever shift strategy transfer power smoothly from gear to gear.
Both, the Hybrid and the Plug-in, use the 6DCT to engage the driver and harness the electric and combustion technologies to best effect, for a sporty and fun drive. That is how they differentiate themselves from other hybrid and plug-in hybrid cars, which are often criticized for ‘rubber band-like’ acceleration.
Enhancing the car’s fuel efficiency and dynamic driving characteristics, the driver can select SPORT or ECO modes. The SPORT function holds lower gears longer and combines power from the engine and electric motor to reward the driver with maximized performance. In ECO mode, the 6DCT optimizes the gear selection for fuel economy, shifting up earlier to higher gears to achieve class-leading fuel economy.
The powertrain components were designed to be very compact and highly efficient. The combined extra weight of the hybrid and plug-in hybrid technology therefore only adds minimal weight to the IONIQ but, significantly increases its efficiency.
Compact electric motor powered by lithium-ion polymer battery
Electric power for the Hybrid and the Plug-in as well as for the Electric is generated by a permanent magnet synchronous motor whose parts were optimized by reducing the thickness of core components (electrical steel sheet) by up to 10% and adopting rectangular-section copper wire to decrease core and copper loss.
Hyundai Motor decided to use a lithium-ion polymer battery pack for all IONIQ models - instead of conventional nickel-metal-hydride batteries. This provides lower memory sensitivity, excellent charge and discharge efficiency along with outstanding maximum output.
Efficient packaging was also taken into consideration as the battery system is located underneath the rear seats so that the usability of the passenger cabin and cargo area is entirely uncompromised in the IONIQ Hybrid, offering cargo space of up to 750 litres. This also holds true for the IONIQ Plug-in and the IONIQ Electric which despite larger batteries both offer generous cargo capacity of up to 650 litres.
An all-electric all-star
The IONIQ Electric offers pure e-mobility through a 28 kWh lithium-ion polymer battery for an estimated maximum range of over 250 km. The instantly available maximum torque of 295 Nm is delivered by the electric motor with a maximum output of 88 kW (120 PS) through the single-speed reducer transmission accelerating the car up to 165 km/h.
The shift by wire system unique to IONIQ Electric enables operation of the car simply by pressing buttons to switch driving modes. Plus it eliminates the routing space required for housing the mechanical linkages between a normal shifter and the transmission, providing more space in the front of the car. The Single Speed Reducer transmission automatically and seamlessly accelerates the Electric and offers SPORT, NORMAL and ECO modes to enhance efficiency and driving characteristics.
Charging the IONIQ Electric’s lithium-ion polymer battery up to 80% only takes about 24 minutes using a 100 kW fast charger. An integrated In-Cable Control Box (ICCB) also allows drivers to charge their IONIQ at a regular household socket. The charging plug of the car is located in a position where gas fillers are normally located.
