The Ioniq Hybrid’s electric motor delivers an estimated 32 kW (43 horsepower) with an estimated maximum torque of 125 lb.-ft., powered by a lithium-ion polymer battery with 1.56 kWh capacity. The battery is efficiently positioned under the rear passenger seats. In combination with the 1.6-liter direct-injected engine, Ioniq Hybrid offers a total system output of 139 horsepower while providing low emissions, outstanding efficiency and range. The Ioniq Hybrid Blue model has an EPA-estimated 58 MPG combined rating, the highest rating of any non-plug-in vehicle sold in the U.S. market.
The Ioniq Electric offers pure electric mobility with a 28 kWh lithium-ion polymer battery for an estimated driving range of 124 miles. The electric motor has a maximum output of 88 kW (118 horsepower) and 218 lb.-ft. of torque mated to a single-speed reduction-gear transmission. The Ioniq Electric has an EPA-estimated 136 MPGe rating, the highest efficiency rating of any electric vehicle sold in the U.S. market.
Advanced battery technology
Further, the powertrain components were designed to be compact and highly efficient. The combined extra weight of the Hybrid and Plug-in Hybrid technology therefore adds minimal weight to the Ioniq, but significantly increases its efficiency. Electric power for the Hybrid and the Plug-in Hybrid, 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 by up to 10 percent and adopting rectangular-section copper wire to decrease core and copper loss. Hyundai uses a lithium-ion polymer battery pack for all Ioniq models which is 20 percent lighter than non-polymer lithium-ion batteries and can be shaped more optimally to the interior than standard cell format batteries. This also provides lower memory sensitivity, excellent charge and discharge efficiency, and outstanding maximum output.
Both efficient packaging and a low center of gravity were taken into consideration as the battery system is located underneath the rear seats so that the passenger cabin and cargo area is uncompromised in the Ioniq Hybrid, offering a total interior volume of an estimated 122.7 cubic feet (more than Toyota Prius). Even the Ioniq Plug-in Hybrid and the Ioniq Electric, despite having larger battery systems, both offer a generous total interior volume of an estimated 119.2 cubic feet.
All Ioniq Electric models are equipped with standard Level-3 DC fast-charging capability. Charging the Ioniq Electric’s lithium-ion polymer battery up to 80 percent only takes about 23 minutes using a SAE Combo Level-3 DC, 100 kW fast-charger. An integrated In-Cable Control Box (ICCB) also allows drivers to charge their Ioniq Electric and Plug-in Hybrid using a standard household electric socket when necessary.
Ioniq Hybrid and Plug-in Hybrid feature a multi-link rear suspension system with dual lower control arms for agile ride and handling coupled with excellent ride quality. In addition, extensive use of aluminum in front and rear suspension components saves around 22 lbs. of weight compared with conventional materials. A reduction of five lbs. per front lower arm unit saves 13 lbs. at the front suspension, while nearly nine lbs. is reduced at the rear suspension. In addition, the placement of the battery systems below the rear seats provides a lower center of gravity for more responsive handling.
The Ioniq Electric applies a torsion-beam rear axle, providing more space for the 28 kWh lithium-ion polymer batteries, placed below the rear seats. Ioniq’s responsiveness and feedback from the steering system is clear and precise, with a quick steering ratio for an engaging and responsive feel. Braking force is optimized for maximum efficiency from the regenerative braking system, helping Ioniq to maintain a steady state of charge (SOC). Regenerative braking also operates with reduced noise, using a third-generation recuperating stopping system. Regenerative braking force can be adjusted to meet the driver’s preference and driving conditions through steering-column-mounted regenerative brake-level control paddles. An Integrated Brake Assist Unit (iBAU) and Pressure Source Unit (PSU) also contribute to quieter operation. This helps ensure ultra-low friction for maximum energy recuperation and efficiency levels.
To suit customers’ varied lifestyles, Ioniq features state-of-the-art infotainment and connectivity features. Ioniq is equipped with a high-definition 7-inch TFT information cluster. With a resolution of 1280 x 720 pixels, it displays all gauge functions (speedometer, drive mode, fuel level). Depending on the selected drive mode, background color and gauges are adapted to always provide the most important and useful information. Within SPORT mode, the display changes into a revolving digital speedometer that is surrounded by an analog-type tachometer, showing engine rpm in red. When choosing ECO mode, the TFT-information cluster simulates the classic speedometer needle.
The driving experience inside Ioniq is enhanced through state-of-the art connectivity features like Apple CarPlay®, Android Auto® and Blue Link®, as well as wireless charging for smartphones. Even more, the 7-inch TFT instrument cluster displays all key driver information with outstanding resolution. Ioniq also allows drivers to integrate their smartphone with the vehicle’s infotainment system by providing both Apple CarPlay® and Android Auto®. Both systems enable users to connect their devices to activate music, telephone or navigation functions with lower distraction levels. Ioniq also offers a wireless inductive-charging pad compatible with both Android- and Apple-based smartphone technologies.
Hyundai is also working with ChargePoint® to further enhance the Ioniq Electric and Plug-in Hybrid ownership experience. ChargePoint has the world’s largest electric vehicle charging network with more than 32,000 locations at which to charge, including more than 400 Express DC fast-charging sites. ChargePoint locations are rapidly expanding, with customer ease of use as a primary goal at every location.
Ioniq owners will receive welcome kits, informing them with key information and benefits in the use of the ChargePoint charging network, and ChargePoint access cards that are easy to activate. In addition, owners will have the capability to conveniently locate ChargePoint chargers on their mobile devices using the MyHyundai/Blue Link app.
