The all-new Sonata benefits from improved interior ergonomics, resulting in a completely driver-focused cabin that incorporates Hyundai Motor’s core interior design principles of safety, intuitiveness and simplicity.
The all-new Sonata provides the luxury feel of a car from the segment above in a mid-size 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 high-grade materials such as leather and metal that are utilized throughout. Maximum seat comfort and convenience is provided through the use of high-end environmentally friendly materials and elegant trim details.
HMI
Central to conveying the all-new Sonata’s premium design qualities is transmitting that experience to the driver and passengers, which Hyundai Motor has achieved through the use of high-grade 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 all-new Sonata, especially at high speeds.
The all-new Sonata has also been fitted with newly configured parts, such as a redesigned steering column in order to accommodate the car’s optimal driver-focused layout. The central console has moved away from the traditional shape and style, and vital information is now displayed in a more effective and easy-to-digest 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 all-new 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 all-new Sonata sets a new standard for ride in a mid-size sedan. Extensive chassis testing and tuning set out to improve the ride characteristics of the all-new 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 driving performance.
As one of the key drivers of Hyundai Motor’s sales, the all-new 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 all-new 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 all-new 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 all-new 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 on-center feel and agile, precise and responsive steering feel are aided by the all-new 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 all-new 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.
Carefully-paired powertrain combinations allow the all-new Sonata to deliver improved drivability over the previous generation model. A key aim during the development of the all-new Sonata was to provide useable performance and drivability while delivering maximum economy under regularly-encountered driving conditions.
4. Safety
Body In White Stiffness
An impressive 51 percent of the all-new 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 all-new Sonata to achieve top-class 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 hot-stamped components has increased by 9 percent over the previous model. Notably, the hot-stamped double-section structure on the B-pillar especially contributes greatly to the excellent performance of the all-new Sonata in crash performance tests.
These changes mean that the all-new 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 sub-frames and strengthen sub-frame mounting points, which also improves suspension responsiveness.
High Technology for Safety
The all-new 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 all-new 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 all-new Sonata’s forward-facing 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 all-new 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 re-activates the high beam headlights to provide a clearer field of vision for the driver.
In crash safety performance tests, the all-new Sonata is expected to achieve top-class results through careful design which ensures the car effectively distributes crash energy. Frontal impact forces are absorbed and distributed through the mid-section to minimize cabin distortion.
In terms of side and rear collision tests, the all-new Sonata provides high levels of occupant protection thanks to inherent strength achieved through the use of hot-stamped 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 weight-optimized hood structure, and a scuttle panel that offers increased head protection safeguards.
5. Convenience
The all-new Sonata delivers uncompromising convenience and generous interior space, together with elegant interior details, offering luxury typically associated with vehicles from the class above.
For front seat passengers, the all-new Sonata features integrated, height-adjustable 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 rear-seat passengers who benefit from heated seats, an electric rear window blind and rear side curtain blinds – a segment-first 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 all-new Sonata, and ensures a light and refreshing atmosphere is maintained at all times. Throughout the vehicle, elegant hand-crafted details can be found, utilizing high-end environmentally-friendly materials.
Advanced vehicle infotainment features, including sophisticated next-generation multi-media systems, ensure the all-new Sonata delivers cutting-edge 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 all-new Sonata also features voice recognition and smartphone integration.
Further convenience is provided by the all-new 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 under-fender kick-sensor, but employs a fender-mounted 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.
6. NVH
Improving NVH levels over the previous generation Sonata was an important area of focus for Hyundai Motor engineers developing the all-new Sonata. A result is noticeably lower audible levels of noise for occupants of the all-new 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.
