Following the world premiere of the allnew Genesis luxury sedan, the allnew Sonata is the
second vehicle to demonstrate Hyundai Motor’s evolved design philosophy, Fluidic Sculpture 2.0.
Fluidic Sculpture embraces the company’s ‘Modern Premium’ brand direction and its
commitment to delivering value beyond expectations.
As applied to the allnew Sonata, Fluidic Sculpture 2.0 retains the original essence of this
wellreceived design philosophy while being further defined by core characteristics, such as
simple and harmonious design with refined fluidic design elements. The allnew Sonata offers
modern style through easytounderstand and pleasing design fundamentals that are expressed
through rich visuotactile colors, materials and overall levels of finish.
While inheriting the sensational design of the previous Sonata, the allnew Sonata has evolved
into a more refined, premium vehicle. Hyundai Motor designers emphasized its inner dignity,
expressed through polished lines and forms.
Hyundai Motor’s latest interpretation of Fluidic Sculpture provides the allnew Sonata with a
highclass, sleek style, a confident stance, and an appearance that is in keeping with Hyundai
Motor’s pioneering family look. Ultimately, the balanced, refined styling of the allnew Sonata
conveys the dynamic driving experience offered by the new model.
A singleframe premium 3D hexagonal grille is a key styling element at the front of the allnew
Sonata, while refined swage lines on its flanks and futuristic features at its rear contribute to its
dynamic shape. Powerful lightemitting diode (LED) daytime running lights and striking rear light
clusters add to the new model’s sophisticated appearance.
The allnew Sonata benefits from improved interior ergonomics, resulting in a completely
driverfocused cabin that incorporates Hyundai Motor’s core interior design principles of safety,
intuitiveness and simplicity.
The allnew Sonata provides the luxury feel of a car from the segment above in a midsize sedan
package, conveying a sense of style and dynamism previously unavailable in a Hyundai Motor
car in this class. In order to convey this sense of luxury the points of contact between the driver
and car were closely examined and enhanced – one result being the highgrade materials such
as leather and metal that are utilized throughout. Maximum seat comfort and convenience is
provided through the use of highend environmentally friendly materials and elegant trim details.
Central to conveying the allnew Sonata’s premium design qualities is transmitting that
experience to the driver and passengers, which Hyundai Motor has achieved through the use of
highgrade materials where constant physical contact with the car’s occupants occurs.
Additionally, significant attention to detail was paid to ergonomics. For example, Hyundai Motor
engineers focused their attention on developing the ideal steering wheel design to ensure the
best possible grip and feel for the driver. After a series of tests the dimensions and style of the
wheel were altered: an overall increase in rim cross section thickness and ergonomic
improvements to grip rests ensure more of the steering wheel surface is in contact with the
driver. Such subtle improvements to detail enhance the driving experience of the allnew Sonata,
especially at high speeds.
The allnew Sonata has also been fitted with newly configured parts, such as a redesigned
steering column in order to accommodate the car’s optimal driverfocused layout. The central
console has moved away from the traditional shape and style, and vital information is now
displayed in a more effective and easytodigest manner, in the instrument cluster facing the
driver. This approach significantly improves visibility for the driver, emphasizing that Hyundai
Motor cares for the drivers of its vehicles.
The switches in the allnew Sonata have been grouped depending on function and are within
easy reach of the driver, facilitating quicker, safer control. Switch feel was also given rigorous
consideration, both in terms of operational force and touch, in order to make locating and
operating functions as easy as possible while driving. The feel and grip of every component
occupants come into contact with has been improved over the previous generation model.
3. Driving Performance
The allnew Sonata sets a new standard for ride in a midsize sedan. Extensive chassis testing
and tuning set out to improve the ride characteristics of the allnew Sonata over its predecessor,
with particular attention being paid to chassis rigidity. Improved twisting and bending strength
have been achieved thanks to greater use of Advanced High Strength Steel (AHSS), which is
twice as rigid and 10 percent lighter than traditional steel, resulting in enhanced safety and
As one of the key drivers of Hyundai Motor’s sales, the allnew Sonata was tested in a variety of
locations worldwide, including the famed Nürburgring in Germany at Hyundai Motor’s dedicated
Technical Center, and the Mojave Proving Ground in California, America, in order to maximize
product competitiveness and satisfy the diverse needs of its global audience.
Reducing road noise, vibrations and enhancing driving dynamics were priorities for the allnew
Sonata development team. These objectives were achieved in part through optimized
suspension damping that gives occupants a soft, silent and comfortable experience. A luxurious
feel is generated through exceptional ride comfort, while the thorough development of handling
and steering feel allows the allnew Sonata to also offer a stable and secure ride over all road
surfaces and in all driving conditions.
In order to improve ride and handling performance, there have been significant changes to the
front and rear suspension, whose structure and geometry have been greatly modified to
enhance responsiveness, handling and stability. The dual lower suspension arms of the rear
suspension of the allnew Sonata distribute lateral forces more effectively than single arm
versions, providing greater freedom to finely tune ride characteristics.
Steering feel has been further increased thanks to the development of the Motor Driven Power
Steering (MDPS) that has resulted in a larger data processing unit, increased logic control cycle
and motor control speed, and greater steering column rigidity. Gentle oncenter feel and agile,
precise and responsive steering feel are aided by the allnew Sonata’s Drive Mode Select
function, which allows the driver to choose the best driving parameters to suit their requirements
or the current road conditions.
In terms of braking, the allnew Sonata boasts superior stopping distances for a car of its class,
combined with an assured, firm feel. Driver confidence is enhanced through the linear delivery of
impressive braking performance, while greater comfort is ensured thanks to minimal intrusion of
noise and vibration into the cabin.
Carefullypaired powertrain combinations allow the allnew Sonata to deliver improved drivability
over the previous generation model. A key aim during the development of the allnew Sonata was
to provide useable performance and drivability while delivering maximum economy under
regularlyencountered driving conditions.
Body In White Stiffness
An impressive 51 percent of the allnew Sonata’s steel is Advanced High Strength Steel (AHSS),
an increase of 30 percent over the previous generation model. These AHSS components are
used to both increase stiffness and more effectively protect passengers, helping the allnew
Sonata to achieve topclass safety ratings according to the company’s internal tests.
The new model has been further strengthened by increasing the use of structural adhesive more
than ten times when compared with the previous generation model. The addition of dual member
structures in main sections of the body has added strength too, while the prevalence of
hotstamped components has increased by 9 percent over the previous model. Notably, the
hotstamped doublesection structure on the Bpillar especially contributes greatly to the
excellent performance of the allnew Sonata in crash performance tests.
These changes mean that the allnew Sonata’s torsional and bending stiffness has increased by
41 percent and 35 percent respectively, compared with its predecessor. Internal testing data
suggest that the new model will score highly in official crash overlap and chassis strength tests.
In addition, high rear impact performance is ensured through reinforced side and cross
members that support the vehicle’s subframes and strengthen subframe mounting points,
which also improves suspension responsiveness.
High Technology for Safety
The allnew Sonata features an abundance of advanced safety features designed to protect its
occupants. A suite of airbags, including driver knee airbag, are fitted to the new model, while
several advanced passive and active systems work harmoniously to ensure the allnew Sonata
is one of the safest vehicles on the road.
Advanced Smart Cruise Control (ASCC) uses radar to automatically calculate the distance to
cars directly ahead and behind. The system maintains a constant gap to the next vehicle and
deploys the Automatic Emergency Braking system if a stationary vehicle is detected ahead –
avoiding a potential collision.
Blind Spot Detection (BSD) monitors traffic around the car in the driver’s blind spots, warning
drivers of possible unseen hazards. This system notifies the driver of hidden hazards through an
indicator symbol on the instrument panel and via illuminated signals on both exterior mirrors. If a
driver should ignore these visual warnings and begin to change lanes, the BSD system
automatically issues an audible warning.
The Lane Departure Warning System (LDWS) uses the allnew Sonata’s forwardfacing sensor
technology to recognize defined lanes situated ahead of the vehicle. If the LDWS detects
departure from the current lane of travel, a warning signal is issued through a visual symbol on
the dashboard, accompanied with an audible warning.
To ensure drivers of oncoming vehicles are not distracted by the allnew Sonata’s headlights at
night, the High Beam Assist (HBA) function automatically detects an approaching vehicle and
dips the high beam headlights to reduce glare. When the system no longer detects a vehicle
ahead, it reactivates the high beam headlights to provide a clearer field of vision for the driver.
In crash safety performance tests, the allnew Sonata is expected to achieve topclass results
through careful design which ensures the car effectively distributes crash energy. Frontal impact
forces are absorbed and distributed through the midsection to minimize cabin distortion.
In terms of side and rear collision tests, the allnew Sonata provides high levels of occupant
protection thanks to inherent strength achieved through the use of hotstamped steel with dual
layer reinforcement, and independent side airbag technology specially designed to protect
occupant’s upper bodies in the event of an accident. Pedestrian safety was also a prime
consideration, resulting in the provision of a durable and weightoptimized hood structure, and a
scuttle panel that offers increased head protection safeguards.
The allnew Sonata delivers uncompromising convenience and generous interior space, together
with elegant interior details, offering luxury typically associated with vehicles from the class
For front seat passengers, the allnew Sonata features integrated, heightadjustable seats that
have been developed to maximize comfort and convenience. They are also vented to cool
passengers under humid conditions, and heated to provide warmth during cold weather, faster
than the previous version.
The high levels of comfort extend to rearseat passengers who benefit from heated seats, an
electric rear window blind and rear side curtain blinds – a segmentfirst feature. Personal reading
lights provide rear passengers with directed illumination, while the new car’s spacious interior
and slim front seat backs mean there is plenty of legroom for all occupants.
A panoramic sunroof brings a sense of the outside into the cabin of the allnew Sonata, and
ensures a light and refreshing atmosphere is maintained at all times. Throughout the vehicle,
elegant handcrafted details can be found, utilizing highend environmentallyfriendly materials.
Advanced vehicle infotainment features, including sophisticated nextgeneration multimedia
systems, ensure the allnew Sonata delivers cuttingedge entertainment and connectivity to
drivers and passengers. A range of options are available, starting with a 3.8” LCD display,
moving up to 8.0” color touchscreen units, each of which utilize intuitive, clear ergonomic
displays. Supporting USB, Bluetooth and iPod connectivity, the allnew Sonata also features
voice recognition and smartphone integration.
Further convenience is provided by the allnew Sonata’s Smart Trunk function. Using the
vehicle’s smart key, the system can be activated (in the user settings menu) to open the trunk
automatically when the smart key is detected near the rear bumper for longer than three
seconds. Unlike competitor systems, the Smart Trunk function does not utilize an underfender
kicksensor, but employs a fendermounted antenna to receive its instruction to operate,
providing an illuminated and audible warning prior to opening. This allows users to keep both feet
on the ground at all times during operation – more convenient and safer when both hands are
full, for example.
Improving NVH levels over the previous generation Sonata was an important area of focus for
Hyundai Motor engineers developing the allnew Sonata. A result is noticeably lower audible
levels of noise for occupants of the allnew Sonata. Levels of engine and transmission NVH
have been kept to a minimum through minimized acceleration noise and additional damping of
the transmission mounting points.
Reduced NVH levels (dB) for the allnew Sonata:
Idle Steering Wheel 107 107
Floor 97 98
Acceleration Noise 51 52
Acceleration Booming 79 80
Road Noise (FRT/RR) 63/65 65/66
Audible (rumbling) road and engine (booming) noise is kept to an absolute minimum inside the
allnew Sonata, thanks to soundproofing materials that have been used to reduce apertures
through which noise could potentially be transmitted into the cabin. Across the available range of
powertrains engineers reduced highRPM booming, refined engine tones to provide a greater
sense of smooth acceleration, and removed unwanted and intrusive additional noises.
Refined suspension damping achieves a soft, quiet and comfortable ride, creating a calm,
luxurious and peaceful ambiance. Improvements to braking performance were also concentrated
on reducing NVH levels, and the allnew Sonata achieves the lowest levels of braking NVH for a
vehicle in its class.
The allnew Sonata benefits from a reinforced firewall that uses an integrated dualmember
construction, increasing strength and improving NVH levels. Sound absorption underneath the
car has also been maximized, with the addition of a specially designed under cover that utilizes
glass fiber reinforced polypropylene expansion board material.
The onroad behavior of the allnew Sonata has been engineered to ensure a sophisticated and
relaxing ride, achieving optimal levels of quietness for a car in its class. A soft, refined attitude
with low volume NVH gives the allnew Sonata a key competitive advantage over its rivals.
The allnew Sonata offers a wide range of engine and transmission options that deliver
enhanced performance. With an emphasis on practicality, the powertrains of allnew Sonata
have been carefully engineered and tuned for precise power delivery and maximum refinement.
A range of MPi and GDi engines deliver maximum drivability in all driving conditions, thanks to
improvements that mean plentiful torque and power are available across a wider range of engine
speeds. Carefullymatched smoothshifting transmissions ensure maximum availability of full
engine output and contribute to a smooth and relaxing ride for occupants. While the allnew
Sonata is equipped with 2.0 CVVL, 2.4 GDi, 2.0 LPi for the Korean market, variations will vary,
depending on each market.
