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 Ioniq Hybrid’s electric motor delivers an estimated 32 kW (43 horsepower) with an estimated maximum torque of 125 lb-ft (169 N·m), 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 an estimated total system output of 139 horsepower (104 kW) while providing low emissions, efficiency and range.

The Ioniq Plug-in Hybrid provides an estimated all-electric range of more than 25 miles, powered by a potent 8.9 kWh lithium-ion polymer battery. The Ioniq Plug-in’s estimated 45 kW (60 horsepower) electric motor is coupled with the 1.6 direct-injected Atkinson four-cylinder Kappa engine.

The Ioniq Electric offers pure electric mobility with a 28 kWh lithium-ion polymer battery for an estimated driving range of 110 miles (177 km). The Electric motor has an estimated maximum output of 88 kW (120 horsepower) and 215 lb-ft (291 N·m) of torque through a single-speed reduction gear transmission. The Ioniq Electric has an estimated 125 MPGe rating.

Six-speed dual-clutch transmission. The Ioniq Hybrid and Plug-in both feature a six-speed EcoShift dual-clutch transmission (DCT), which features best-in-class transfer efficiency through the use of low-friction bearings and low-viscosity transmission oil, and is able to achieve a mix of driving performance and fuel efficiency.

The Ioniq Hybrid and the Plug-in both use a dual-clutch transmission to engage the driver for a spirited and fun-to-drive character. This is an important differentiator for Hyundai from the majority of other hybrid and plug-in hybrid cars that use a Continuously Variable Transmission, which have been criticized as having “rubber band-like” acceleration.

Enhancing the car’s fuel efficiency and dynamic driving characteristics, the driver can select either SPORT or ECO modes. The SPORT function holds lower gears longer and combines power from the engine and electric motor for maximum performance. In ECO mode, the DCT optimizes gear selection for efficiency, upshifting earlier to achieve class-leading fuel economy.

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, as well as for the Electric, is generated by a permanent magnet synchronous motor the parts of which were optimized by reducing the thickness of core components by up to 10% and adopting rectangular-section copper wire to decrease core and copper loss.

Battery technology. Hyundai uses a lithium-ion polymer battery pack for all Ioniq models which is 20% 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 and the Ioniq Electric, despite larger batteries, both offer a generous total interior volume of an estimated 119.2 cubic feet.

Charging the Ioniq Electric’s lithium-ion polymer battery up to 80% takes about 20 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 at a standard household electric socket.

Lightweighting focus. Ioniq sought significant weight reduction targets without compromising fun-to-drive and comfort characteristics. Ioniq uses aluminum in the hood and tailgate, reducing weight by 27 lbs (12.25 kg) compared with conventional steel and no measurable disadvantages in noise or vibration.

In addition, the lead-acid auxiliary 12V battery found in competitors’ hybrid models has been omitted, resulting in an approximate 26-pound (11.8 kg) reduction in weight. Lightweighting also extended to less obvious areas such as the cargo-screen cover. With higher usage of lightweight components and a more compact build, the cargo-screen cover is about 25% lighter than the types used in other Hyundai models.

Ioniq Hybrid and Plug-in feature a multi-link rear suspension system with dual lower control arms, minimizing ride and handling compromises often associated with less sophisticated suspension geometry. In addition, extensive use of aluminum in front and rear suspension components saves around 26 lbs of weight compared with conventional materials. A reduction of 5 lbs (2.3 kg) per front lower arm unit saves 10 lbs (4.6 kg) at the front suspension, while nearly 16 lbs (7.3 kg) 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 a sporty 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. 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.

Michelin tires give Ioniq enhanced levels of efficiency, as the car is fitted with low-rolling-resistance tires for 15-, 16- and 17-inch wheels, plus the car’s larger 17-inch wheels (Ioniq Hybrid) are fitted with high-silica tires for better all-around performance. The multi-link suspension system of Ioniq Hybrid and Plug-in has been adapted to work most efficiently with low-rolling-resistance tires.

Exterior. In crafting the exterior appearance of Ioniq, Hyundai designers concentrated on its future-focused character, fundamental to its appeal. A fluid exterior shape and natural air flow channels emphasize aerodynamic body lines and surface volumes. A sporty, hatchback-like profile is inspired by aerodynamic efficiency, complementing the soft lines and surfaces that trace the car’s outline. These attributes combine to boost aerodynamics further, which, when combined with various other smart efficiency solutions, produce a class-leading 0.24 coefficient of drag.

Applications such as front wheel air curtains, a rear spoiler and diffuser, side sill moldings, floor undercover and a closed-wheel design all contribute to the car’s high aerodynamic efficiency. Additionally, the Hybrid and Plug-in hybrid feature a three-stage active air flap integrated with the front grille, while a sleek, closed front fascia differentiates the Electric model.

Smart and efficient air conditioning. To provide a pleasant, comfortable and refreshing interior climate without using unnecessary amounts of energy, the Ioniq climate control can be switched to an efficient operation mode. Recirculated air is maximized when air-conditioning or heating, reducing ventilation losses and increasing the overall efficiency of the system. Also, the fully-automatic climate control can be set to ‘Driver only’ mode, thereby reducing the load of both air-conditioning and heating on the overall powertrain.

Recycled and renewable materials. A key characteristic of the Ioniq is its innovative use of recycled or ecologically-sensitive materials. The interior door covers are made of plastic combined with powdered wood and volcanic stone while providing the same quality appearance of typical plastic-based materials. The softer, more natural feel is achieved along with less reliance on oil-based products. This approach extends to other areas of the car as well. Raw materials extracted from sugar cane are partly applied on the headliner and carpet. Paint with renewable ingredients extracted from soybean oil is used to achieve lustrous metallic colors on key components.

Infotainment System. 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.

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 (Qi standard) for mobile phones.

Blue Link. The Ioniq lineup offers the Hyundai Blue Link connected car system with enhanced safety, diagnostic, remote and guidance services. Blue Link brings connectivity directly into the car with technology like Remote Start with Climate Control, Destination Search powered by Google, Remote Door Lock/Unlock, Car Finder, Enhanced Roadside Assistance, and Stolen Vehicle Recovery. Blue Link features can be accessed via buttons on the rearview mirror, the MyHyundai.com web portal, or via the Blue Link smartphone app. Some features can also be controlled via Android Wear and Apple Watch smartwatch apps. Owners of Ioniq Plug-in and Electric will also be able manage and monitor their car’s charging schedule remotely via the Blue Link smartphone app. Charge scheduling is ideal for individuals that have lower electricity rates during off-peak hours.

Safety. Ioniq’s light-yet-rigid body is the result of advanced design, construction methods and materials. Featuring 53% Advanced High Strength Steel, the chassis benefits from superior rigidity for responsive handling and safety, with high impact-energy absorption and minimized cabin distortion to protect passengers in the event of a collision. This rigid structure also leverages 475 feet of advanced structural adhesives in its design, simultaneously yielding both lightweighting and rigidity benefits.

A number of innovative active and passive safety features help protect Ioniq drivers and passengers. The list of active safety features includes Blind Spot Detection, which works with Lane Change Assist and Rear Cross-Traffic Alert to warn the driver of any surrounding vehicles, passengers or objects that could lead to a collision. A Lane Departure Warning System (LDWS) is also offered, which sounds an alarm as the car moves over lane lines.

The Ioniq is also fitted with Automatic Emergency Braking (AEB) with Pedestrian Detection, an advanced active safety feature that alerts drivers to emergency situations, even braking automatically as required. With sensor-fusion technology that utilizes the front radar and camera sensors, AEB operates in three stages. Initially warning the driver visually and acoustically, it controls the brake according to the collision danger stage, applying maximum braking immediately before an imminent collision. When a vehicle or pedestrian is sensed in front of the car, the system is activated, operating at speeds of more than 5 mph, and minimizes damage when a collision is otherwise unavoidable.

Using front radar sensors, Smart Cruise Control allows a constant speed and following distance to be maintained from the vehicle ahead without depressing the accelerator or brake pedals; it is automatically cancelled when speed drops to 5 mph or below. Ioniq Electric takes it a step further by providing Advanced Smart Cruise Control, providing fully automatic stop/start function as well. A Tire Pressure Monitoring System also helps ensure each individual tire is properly inflated. A total of seven airbags, including a knee airbag for the driver, help protect the vehicle’s occupants in the event of a collision. Body structure improvements, complemented by a high-strength fiber-reinforced rear bumper fascia make the entire Ioniq line-up strong and durable in the event of a crash.
