Hyundai Ioniq hybrid and electric models headed to U.S. showrooms

Hyundai has begun shipping their Ioniq models to dealerships. The eco-focused Ioniq is the first vehicle to offer three distinct electrified powertrains on a single, dedicated vehicle platform.

“Ioniq will attract an entirely new group of eco- and efficiency-oriented buyers in the U.S. market,” said Mike O’Brien, vice president of Corporate and Product Planning, Hyundai Motor America. “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, enjoyable to drive, low-emissions vehicle without compromise to their daily lifestyles.”

The Ioniq Hybrid and Ioniq Plug-in Hybrid both feature a new Kappa 1.6L direct-injected Atkinson-cycle four-cylinder engine with an unsurpassed thermal efficiency of 40 percent, 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 quick-shifting six-speed double-clutch transmission. The high-efficiency electric motor can operate at speeds up to 75 MPH 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., 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. 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 Plug-in Hybrid provides an all-electric range of more than 27 miles based on preliminary internal estimates, powered by a potent 8.9 kWh lithium-ion polymer battery. The Ioniq Plug-in Hybrid’s estimated 45kW (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 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.

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

Both models use a dual-clutch transmission a 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.

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 improved fuel economy.

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 batteries, both offer a generous total interior volume of an estimated 120.0 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 approximately 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 using a standard household electric socket.

Ioniq uses aluminum in the hood and tailgate, reducing weight by 27 lbs. 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 for the Ioniq Hybrid, resulting in an approximate 26-pound reduction in weight. Lightweighting also extended to less obvious areas like the cargo-screen cover. With higher usage of lightweight components and a more compact build, the cargo-screen cover is about 25-percent lighter than the types used in other Hyundai models.

Ioniq has enhanced state-of-the art connectivity features like Apple CarPlay, Android Auto and Blue Link, as well as wireless charging for smartphones. The 7-inch TFT instrument cluster displays all key driver information with outstanding resolution. Advanced safety features include Automatic Emergency Braking with Pedestrian Detection, Lane Departure Warning, Blind Spot Detection and Rear Cross-Traffic Alert, for high levels of both active and passive vehicle safety.

Ioniq Hybrid MSRP starts at $22,200, Ioniq Electric starting MSRP is $29,500.
