2011 Hyundai Sonata U.S. debut
Hyundai introduced its all-new 2011 Sonata at the 2009 Los Angeles Auto Show. This marks the North American debut of the latest version of the popular midsize sedan, introducing Hyundai’s “Fluidic Sculpture” design language and an all four-cylinder engine lineup to the U.S. market.
The exterior of the all-new Sonata is long, light and low. The high beltline allows for a long, sleek roofline accented by the third window. A monoform side profile includes flowing lines highlighted by a Hyundai signature chrome accent that spans the length of the car. Normally, this type of trim is only found around the windows. On the new Sonata, this trim extends out from the headlamps, juts up along the hood and through the beltline. The face is bold with a large powerful chrome grille and headlamps that integrate precise details.
The sleek design, combined with Hyundai’s expertise in interior packaging, has produced an interior that delivers class-leading comfort, functionality and practicality. A sleek roofline typically compromises headroom and interior volume but, at 120.2 cubic feet, the Sonata has the most interior volume of its key competitors. It is so spacious, Sonata continues to be classified by the Environmental Protection Agency (EPA) as a Large car, truly a “class above” Camry, Altima, Fusion and Malibu (all are categorized as Midsize cars). Even in trunk room, the Sonata shines. Sonata’s 16.4 cu.ft. of trunk space gives it a 9.3% advantage over the Camry, and a 17.1% advantage over Accord.
The new Sonata will launch with Hyundai’s new Theta II GDI 2.4L four-cylinder engine with a Gasoline Direct-Injection (GDI) fuel delivery system, which contributes to improved fuel efficiency and lower emissions. Sonata is the first midsize sedan to adopt GDI technology as standard equipment in a naturally aspirated powertain. This shorter, more direct path of fuel delivery, allows for greater control of the fuel mixture at the optimum moment, thus improving efficiency. The fuel is injected by a camshaft-driven, high pressure pump that operates at pressures up to 2,175 psi. Direct injection also utilizes a higher than normal 11.3:1 compression ratio for increased power. The pistons are “dished” to increase combustion efficiency in the cylinder. This powerplant will deliver best-in-class fuel economy, best-in-class four-cylinder horsepower and best-in-class torque.
Sonata delivers an impressive 23 mpg city/35 mpg highway estimated fuel economy rating with the available six-speed automatic transmission with SHIFTRONIC. (When equipped with the six-speed manual, the Sonata achieves an estimated 23 mpg city/34 mpg highway fuel economy rating). The preliminary horsepower and torque ratings for the Theta II GDI are 198 horsepower and 184 lb-ft of torque. In the SE trim which includes a standard dual exhaust, the engine delivers 200 horsepower. This high-tech, all-aluminum, 16-valve engine features Continuously Variable Valve Timing (CVVT) on both camshafts and a Variable Induction System (VIS) for better engine breathing. A version of this engine also meets Partial Zero Emission Vehicle (PZEV) standards.
Next year, Hyundai will add a 2.0-liter Theta II turbocharged GDI four-cylinder engine and a 2.4-liter Hybrid Blue Drive model featuring Hyundai’s breakthrough lithium polymer battery pack. Details about these powertrains will be announced at the 2010 New York Auto Show. Sonata’s innovative segment first powertrain lineup is a key driver of Hyundai’s goal to be the most fuel-efficient automaker on the planet.
Hyundai’s commitment to making the Sonata extremely fuel efficient continues with a six-speed automatic transmission with SHIFTRONIC manual control or a standard six-speed manual transaxle.
An advanced four-wheel independent suspension system combines a supple ride with precise handling and steering response for Sonata GLS and Limited models. Sonata uses MacPherson strut front and multi-link rear suspension systems with increased travel for improved wheel control and a smoother ride. All four wheels are controlled by coil springs, fade-resistant gas-charged dampers and stabilizer bars. The suspension has been optimized to keep the vehicle flat during corning and provide quick turn-in response. The rear suspension uses aluminum components to reduce weight and improve suspension performance. The GLS and Limited models also use advanced low-rolling resistance tires to improve fuel economy while maintaining good ride and handling performance.
The Sonata SE is an even more exciting and willing partner for drivers who prefer sportier ride and handling dynamics. The sport-tuned suspension features stiffer springs and larger stabilizer bars, resulting in a 20% increase in roll stiffness. Unique SE dampers, including monotube shocks in the rear are used to control the more aggressive suspension. Low profile 18-inch tires round out the unique chassis components of the Sonata SE.
Audio enthusiasts with even more demanding tastes will be impressed by the AM/FM/XM/DVD/MP3 audio system with touch-screen navigation that includes a 400-watt external amplifier, dedicated Dual Voice Coil (DVC) subwoofer, eight-channels and nine Infinity speakers available on the Limited. Infinity and Hyundai engineers worked together during the early stages of development to integrate the speakers into Sonata’s interior. The team spent hundreds of hours fine-tuning the system for the cabin’s unique acoustic attributes.
Touch-screen navigation is available on all trim levels and includes a high-resolution screen. This system provides new features including Bluetooth streaming audio capability. This easy-to-use unit can be controlled via 6.5-inch WVGA touchscreen or voice-activation by headliner-mounted microphone.
The system features 8GB of flash memory and comes matched with a sound system that plays compact discs, accesses digital music files via Bluetooth streaming audio or allows driver and passenger to access their personal listening devices through the iPod/USB/auxiliary inputs. Bluetooth audio wirelessly streams music from select mobile phones to the head unit. Also, with a Bluetooth-enabled phone one can look up a local restaurant and call for reservations before plotting the route. The XM Satellite Radio interface is also integrated into the navigation unit and features channel logos, real-time NavTraffic and XM Data services such as WX Satellite Weather®, XM Stock Ticker and XM Sports Ticker. The system is also updateable via the USB.
