Following the legacy of the first generation model launch in 1985, the seventh generation All-new Sonata is the result of an ambitious project that began under the project name LF in 2011 and was completed three years of development.
With “innovation of fundamentals” as its theme, the vehicle is an expression of the future direction that Hyundai Motor is aiming for.
It is more refined and elegant exterior reflects the Fluidic Sculpture 2.0 design. Its ergonomic interior was designed to maximise drivers’ emotional quality satisfaction. Its reinforced body frame and improved platform significantly enhance safety and deliver a dynamic driving performance.
The All-new Sonata delivers greater power at practical speeds and offers improved fuel economy.
Noteworthy improvement in safety
The overall safety of the All-new Sonata has been upgraded with dramatically improved rigidity of the body and the installation of a six-airbag system. The use of Advanced high-strength steel (AHSS) that is 10% lighter but two times stronger than conventional steel has been increased more than 2.4 times, from 21% to 51%, to improve safety and driving performance. Boosting the use of structural adhesives from 11m to 119m, increasing hot stamped parts from five to 16, and reinforcing main sections of the body with dual member structures have improved resistance against bending and distortion from external shocks.
The US government’s National Highway Traffic Safety Administration (NHTSA) conducts vehicle testing each year to give consumers information about crashworthiness, collision avoidance and other areas that improve the safety of new vehicles. The 2015 Sonata has received NHTSA’s highest 5-Star overall safety rating for 2015. The 2015 Sonata also earns the highest safety rating from the Insurance Institute for Highway Safety (IIHS) in US.
Improved driving performance under practical speeds
The All-new Sonata is available with a 2.0 and 2.4 MPi gasoline (Brunei), 2.4 GDi gasoline, or 2.0 T-GDi gasoline engine. The engines offer greater responsiveness and noticeably improved driving performance as a result of diverse new technologies that improve engine output and deliver high acceleration at low to medium speeds that are most commonly used. Moreover, in spite of the increase in body size and body weight from 1,415 kg to 1,460 kg due to groundbreaking safety enhancements, fuel mileage was slightly improved through the use of diverse fuel-saving technologies. In addition, by installing a six-speed, front-wheel drive automatic transmission, it offers a smoother and more efficient transmission as well as outstanding acceleration.
The lightweight and responsive 2.0 MPi gasoline engine delivers a maximum 20.0 kg•m of torqueat 4,000 rpm and a maximum 157ps at 6,200 rpm. Powerful but also quiet and responsive 2.4 MPi gasoline engine delivers a maximum 23.3 kg•m of torque at 4,000 rpm and a maximum 178ps at 6,000 rpm.
HMI (Human Machine Interface) design was used in designing the All-new Sonata to maximise users’ comfort and emotional satisfaction. The navigation screen was placed on the same level as the instrument panel to minimise the driver’s eye movement, and pushbuttons on the steering wheel were placed for easy operation with the thumbs while driving. Switches for features such as air conditioning and cruise control were grouped according to function and placed within easy reach of the driver for quicker, safer operation while driving.
Improved driving experience and comfort
The All-new Sonata features important changes that enhance stability and comfort, precision handling, and cabin silence to improve driving performance and fuel economy. A best-in-class drag coefficient of 0.27 Cd was achieved through design adjustment that improved aerodynamic performance, such as lowering the tip of the hood and extending the under cover. In addition, to supply agile steering and stable handling, the vehicle is equipped with speed-sensitive Motor driven power steering (MDPS). Finally, to upgrade NVH (Noise, Vibration, and Harshness) performance, several measures, such as increasing the stiffness of the brake system booster and changing the pedal were implemented.
In addition, to greatly reduce the risk of crashes while driving, the All-new Sonata comes equipped with a Blind spot detection (BSD) and Rear cross-traffic alert (RCTA) that warns drivers about fast-approaching vehicles in blind spots or the rear of the car. Other new technologies and convenience features amplify the true value of Sonata.
Dynamic and elegant styling
The All-new Sonata showcases the more elegant and refined design characteristic of Fluidic Sculpture 2.0. The front features a new, more sophisticated hexagonal radiator grille, and the sides feature a more restrained lines and volumes that are more modern. The voluminous rear bumper offers visual stability, similar to the horizontal layout of the interior whose primary consideration is users’ convenience, but nevertheless exudes outstanding sophistication.
