Battery-Electric, Hybrid and Plug-In Versions for 2017:
‘A Comprehensive Eco-Lifestyle Transportation Solution’
Hyundai is promoting its new Ioniq for 2017 as the “world’s first dedicated vehicle platform with three electrified low- and zero-emission powertrain choices.” The new car will be available as a 100% battery-electric, as a fuel-saving hybrid, and as a plug-in hybrid electric vehicle.
“The Hyundai Ioniq is an important milestone in Hyundai’s global sustainability strategy,” the company said at the New York International Auto Show.
“Ioniq will attract an entirely new group of eco- and efficiency-oriented buyers in the U.S. market,” Hyundai Motor America corporate and product planning VP Mike O’Brien said in the Ioniq announcement.
Late This Year and Mid-Next
U.S. availability of the 100-plus-mile battery-electric and the traditional hybrid versions of the Ioniq is now expected for the fourth quarter of this year, with the Ioniq PHEV, with all-electric range of about 25 miles, coming to the U.S. in the second quarter of 2017.
“With outstanding powertrain flexibility, design, connectivity, and advanced technologies, Ioniq meets the needs of a large and growing group of buyers needing a highly efficient, low-emissions vehicle without compromise to their daily lifestyles,” O’Brien said.
A 1.6-Liter Kappa Engine
The Ioniq Hybrid and Ioniq Plug-in Hybrid will feature a new Kappa 1.6 direct-injected Atkinson-cycle four-cylinder engine with “unsurpassed” thermal efficiency of 40%, Hyundai says, delivering an estimated 104 horsepower and an estimated 109 lb.-ft. of torque. “This engine has been specifically tailored to the hybrid application and is combined with a smooth shifting six-speed double-clutch transmission – differentiating Ioniq from its key competitors with a more dynamic and engaging driving experience,” the manufacturer says.
“The high-efficiency electric motor has a pure electric driving mode and delivers instantaneous torque at low speeds, with available power-assist at higher vehicle speeds.” The motor will deliver an estimated 32 kilowatts of power (43 horsepower) with an estimated maximum torque of 125 foot-pounds. It is powered by a lithium ion polymer battery with capacity of 1.56 kilowatt-hours.
Dual Clutch Transmission Said Better than CVT
The Ioniq PHEV will have “a potent” 8.9-kilowatt-hour lithium ion polymer battery and a 45-kilowatt/60 horsepower electric motor coupled with the 1.6-liter four-cylinder Kappa engine.
The dual clutch transmission for the Ioniq Hybrid and the PHEV will “engage the driver for a spirited and fun-to-drive character.
“This is an important differentiator from the majority of other hybrid and plug-in Hybrid cars that use a continuously variable transmission, which are often criticized as having ‘rubber band-like’ acceleration,” Hyundai says.
The Ioniq Electric – for pure electric mobility – is to have a 28-kilowatt-hour lithium ion polymer battery for an estimated single-charge driving range of 110 miles. The Ioniq Electric’s motor has an estimated maximum output of 88 kilowatts (120 horsepower) and 215 foot-pounds of torque through a single-speed reduction gear transmission. The Ioniq Electric has an estimated 125 MPGe rating.
Lithium Ion Polymer Batteries
Hyundai is touting lithium ion polymer battery technology for all Ioniq models – “20% lighter than non-polymer lithium-ion batteries and can be shaped more optimally to the interior than standard cell format batteries.” The polymer technology also provides “lower memory sensitivity, excellent charge and discharge efficiency, and outstanding maximum output.”
The Ioniq Electric will be chargeable to 80% using 100-kilowatt SAE Combo Level 3 DC fast-charger.
All three Ioniq models employ permanent magnet synchronous motors.
Hyundai cautions that technical specifications and emission values released at the New York show “are preliminary target values and subject to homologation.”
