2019 Hyundai Ioniq plug-in hybrid beats EPA MPG

2019, Hyundai, Ioniq

Hyundai is offering three different models of the 2019 Hyundai Ioniq; Plug-in Hybrid, hybrid and electric. I drove the plug-in hybrid with the base MSRP of $29,350 and an out-the-door MSRP of $33,335.

I have solar panels, so the electricity was free, and the first twenty-seven miles of energy was on electricity. There were only a couple of times I went more than twenty-seven miles, but we had a full tank of gasoline to take care of the extra miles.

A bonus people don’t talk about is energizing your car overnight when you’re not at home. We were at a hotel in Los Angeles with a plug-in vehicle and didn’t plug-in because we were concerned about theft of the plug. In the Hyundai plug-in, the car locks the minute you plug it in, and you can’t unplug the hatchback unless you have the key.

The 2019 model year, with new and broader applications of active safety features, enhanced voice-recognition features and standard remote charge management for Plug-in and Electric models.

Hyundai’s approach for the Ioniq line delivers a strong design and driving experience coupled with the latest in safety and convenience technologies, making it an appealing choice for a wide range of buyers. 2019 Ioniq models will be available at Hyundai dealerships this summer.

Every Ioniq high energy efficiency powertrain without compromising driving performance while leaning toward a cleaner means of mobility.

The Ioniq Plug-in Hybrid powertrain combines the best of the Electric and Hybrid powertrains without typical eco powertrain compromises. The Plug-in Hybrid features a Kappa 1.6L direct-injected Atkinson-cycle four-cylinder engine with an unsurpassed thermal efficiency of 40 percent and delivers 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 dual-clutch transmission, differentiating Ioniq from its key competitors with more dynamic and engaging driving experience. The Ioniq Plug-in Hybrid’s 44.5 kW (60 horsepower) electric motor couples a 1.6-liter direct-injected Atkinson four-cylinder Kappa engine. 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 Plug-in Hybrid provides an estimated all-electric range of 29 miles, 119 MPGe in EV mode and 52 MPG in hybrid mode, powered by a potent 8.9 kWh lithium-ion polymer battery.

The Ioniq Hybrid Blue model has an estimated 58 MPG combined rating, the highest rating of any non-plug-in vehicle sold in the U.S. market. The Ioniq Hybrid’s electric motor expects delivery of 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 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 Electric estimates 136 MPGe rating, the highest efficiency rating of any electric vehicle sold in the U.S. market. The BEV offers pure electric mobility with a 28.0 kWh lithium-ion polymer battery for a driving range of around 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.

Six-speed dual-clutch transmission

The Ioniq Hybrid and Plug-in Hybrid 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 can achieve a unique mix of driving performance and fuel efficiency 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 Continuously Variable Transmissions, often 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 the power from the engine and electric motor for maximum performance. Also in SPORT mode, the gasoline engine remains on, and the electric motor acts as a power assist for maximum responsiveness. In ECO mode, the DCT optimizes gear selection for efficiency, upshifting earlier to achieve class-leading fuel economy. Both Hybrid and Plug-in Hybrid models have steering-wheel paddle shifters for an even more engaging driving experience.

Advanced Battery Technology

Further, 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 system 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 battery 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 the passenger cabin and cargo area are 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.

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. 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 a 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.

Driving performance – low- to zero-emission mobility without compromise Ioniq Hybrid and Plug-in Hybrid feature a sophisticated 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 about 22 lbs. of weight compared with conventional materials. 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 28.0 kWh lithium-ion polymer batteries, placed below the rear seats. Ioniq’s responsiveness and feedback from the steering system are 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 regeneration and efficiency levels.

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


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 an industry-leading 0.24 coefficient of drag. In addition to Ioniq aerodynamics, further design details distinguish the Hybrid and Plug-in Hybrid from the Electric models, creating their unique identities:

Ioniq Plug-in Hybrid

In addition to general exterior design details from the hybrid, such as the hexagonal grille and the vertical C-shaped LED daytime running lights, the Ioniq Plug-in Hybrid also features low-beam LED headlamps. The Plug-in Hybrid also integrates a charging portal into the left front fender for the 8.9 kWh lithium-ion-polymer battery system. Specially-designed 16-inch alloy wheels further differentiate the Plug-in Hybrid model.

Ioniq Hybrid

The front of the Ioniq Hybrid is characterized by the Bi-Xenon HID headlights surrounded by C-shaped LED positioning lamps. Hyundai’s signature hexagonal grille and vertical C-shaped LED daytime running lights further convey the purity of design. Contrasting colors at the base of the bumper fascia add individual character and has two unique interior environments. The Ioniq Hybrid features specially-designed two-tone contrasting 15-inch eco-spoke or 17-inch alloy wheels.

Ioniq Electric

Ioniq Electric conveys a unique front perspective: with lower powertrain cooling required, the grille is a sleek, clean surface. The Electric model also features HID Xenon headlamps with Dynamic Bending Light (DBL) and LED tail lamps with a unique pattern and identity for the rear view, as well as unique 16-inch eco-spoke alloy wheels.
