Hyundai Ioniq models offer a sleek, aerodynamic
silhouette with a class-leading 0.24 Cd derived from carefully designed
surfaces. Its fluid exterior shape and smooth air flow channels emphasize
aerodynamic body lines and design forms.
Hyundai's Ioniq line-up calls upon two key factors,
efficiency and technology, in its design, which combine to create both a unique
and forward-looking appearance. Throughout the entire development phase,
engineers and designers worked closely to ensure that form and function evolved
simultaneously in a complementary fashion. Distinguished exterior design sets
Ioniq apart from its competitors as advanced technologies are integrated with
the overall design.
POWERTRAIN CHOICE
Developed for high energy efficiency without
compromising driving performance, every Ioniq powertrain represents a unique
and uncompromising solution towards a cleaner means of mobility.
The Hyundai Ioniq Hybrid and Ioniq Plug-in Hybrid both
feature a new Kappa 1.6 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 smooth
shifting six-speed double-clutch transmission - differentiating Ioniq from its
key competitors with a more dynamic and engaging driving experience. 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 Hyundai 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 an
estimated total system output of 139 horsepower while providing low emissions,
outstanding efficiency and range.
The Hyundai 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 45kW (60 horsepower)
electric motor is coupled with the 1.6 direct-injected Atkinson four-cylinder
Kappa engine.
The Hyundai Ioniq Electric offers pure electric
mobility with a 28 kWh lithium-ion polymer battery for an estimated driving
range of 110 miles. The Electric motor has an estimated maximum output of 88 kW
(120 horsepower) and 215 lb.-ft. of torque through a single-speed reduction
gear transmission. The Ioniq Electric has an estimated 125 MPGe rating.
Six-speed dual-clutch transmission
The Hyundai 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 the Hyundai Ioniq Hybrid and the Plug-in use a
dual-clutch transmission to 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.
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.
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, 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 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 percent only 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.
EXTERIOR DESIGN
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.
In addition to Ioniq aerodynamics, further design
details distinguish the Hybrid, Plug-in and Electric models from one another,
creating their unique identities:
Hyundai Ioniq Hybrid
The front of the Hyundai 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 purity of design. Contrasting colors at the base of the
bumper fascia add individual character and can be paired with two unique
interior environments. The color choices for Ioniq models include Black Noir
Pearl, Symphony Air Silver, and Electric Blue Metallic, Ceramic White, Siena
Brown and Summit Gray. The Ioniq Hybrid features specially-designed two-tone
contrasting 15- or 17-inch alloy wheels.
Hyundai 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 also features low-beam LED headlamps. The
Plug-in also integrates a charging portal into the left front fender for the
lithium-ion polymer battery. Specially-designed 16-inch alloy wheels further differentiate
the Plug-in Hybrid model.
Hyundai Ioniq Electric
Hyundai Ioniq Electric conveys a unique front
perspective: without a need for extensive powertrain cooling, the grille is a
sleek and clean surface. The Electric model also features LED low-beam front
headlamps and rear combination lamps with a unique pattern and identity for the
rear view, as well as unique eco-spoke alloy wheels.
INTERIOR DESIGN
In keeping with its exterior, the interior of Ioniq
captures the model's futuristic qualities, with a 'Purified High-tech' design
concept. A smooth, elegant and clutter-free theme and efficient use of interior
space complements a logical, structured approach applied to the layout of
controls for intuitive operation. Materials for the interior were chosen with
an ecologically-sensitive focus and are used to create a simple and clean look
throughout the car, giving the interior a sleek, light and purified feel.
The driver and passenger of the Electric model will
also notice that there is more room between the front seats. This is achieved
via a button-activated shift-by-wire system free of mechanical linkage. The
Ioniq also features an electronic parking brake (EPB), conserving space in the
center console.
Advanced aerodynamics
The Hyundai Ioniq sleek silhouette and its simple,
carefully wrought contours assist the efficient management of airflow around
the exterior. Applications like 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 of 0.24 Cd. 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.
Eco-focused materials create clean and sustainable
interior ambience
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
To suit customers' varied lifestyles, Hyundai 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.
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.
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, 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.
Driving performance - low- to zero-emission mobility
without compromise
The driving performance of the Hyundai Ioniq line-up
is among the best in its segment due to a powertrain that is adapted to deliver
efficient mobility without compromise. Ride and handling, as well as noise,
vibration and harshness levels, are tuned towards superior ride quality, while
insulation in the instrument panel minimizes engine compartment noise
intrusion. Damping in the floor panels, as well as enhanced A- and B- pillar
insulation, thicker window glass and noise-cancelling film on the windshield,
further improve the quiet and comfortable driving experience.
Hyundai Ioniq Hybrid and Plug-in feature a
sophisticated 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 five lbs. per front lower arm unit
saves 10 lbs. at the front suspension, while nearly 16 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 Hyundai 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.
Comfort and convenience
The Ioniq line-up delivers great driver and passenger
convenience, bringing to the segment a range of considerations for which other
Hybrid, Plug-in Hybrid and Electric vehicles may have compromised. All Hybrid
components are cleverly packaged to maximize space and flexibility of the
interior. In fact, the Ioniq Hybrid offers best-in-class cargo space by
positioning the battery underneath the rear seats. Moreover, the rear seats can
fold down, providing an estimated 26.5 cubic feet of cargo area volume,
allowing large pieces of luggage to be stowed with ease. All Ioniq models also
offer generous front and rear headroom, shoulder and leg room, while a memory
driver's seat and heated front seats offer additional comfort.
Blue Link®
The Hyundai 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 - innovative active and passive safety features
Ioniq's light-yet-rigid body is the result of advanced
design, construction methods and materials. Featuring 53 percent 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 light weighting and rigidity benefits. A host
of innovative active and passive safety features help protect Ioniq drivers and
passengers. These electronic systems are class-leading as Ioniq continues to
break the mold for alternative fuel vehicle safety standards. The long 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 Hyundai 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.
