2005 Hyundai Sonata news, pictures, and information

2005 HYUNDAI SONATA CONTINUES TO BE THE SMART BUY

Sonata GLS and LX models are fitted wîth Hyundai's sophisticated 2.7-liter Delta V6 engine as standard equipment; it's optional on the base Sonata. This is the same powertrain used in the new Hyundai Tucson sport utility vehicle, the sporty Hyundai Tiburon coupe, the Santa Fe and the Sonata. Exceptionally quiet, smooth and refined, the Hyundai Delta engine is an all-aluminum 2.7-liter V6 DOHC powerplant that develops 170 horsepower at 6,000 rpm and 181 lb-ft of torque at 4,000 rpm.


At its heart is an advanced engine management system, which integrates fuel and ignition controls, providing maximum performance and fuel economy while reducing emissions. The Powertrain Control Module (PCM) monitors major systems affecting performance, emissions and smoothness.

With its 10.0:1 compression ratio, the Delta V6 delivers excellent torque output over a wide RPM range. Acceleration is smooth and responsive in all types of driving conditions.

The base Sonata is equipped wîth Hyundai's proven 2.4-liter, DOHC Sirius II four-cylinder engine rated at 138 horsepower at 5,500 RPM and 147 lb-ft of torque at 3,000 RPM.

With an aluminum DOHC cylinder head and four valves per cylinder, the Sirius II engine offers smooth performance and refined operating characteristics. Advanced features include dual balance shafts, hydraulic valve-lash adjusters, a toothed-belt camshaft drive, aluminum oil pan and a serpentine accessory belt.

Advanced Suspension Design

The Hyundai Sonata features a double-wishbone front suspension and a multi-link rear suspension. This combination provides a balance between the smooth ride of a luxury car and the handling performance of a sport sedan. (concept carz)

The double-wishbone suspension consists of upper and lower A-arms. The upper A-arm is rotated to minimize camber changes, helping the front wheels remain upright and in full contact wîth the road surface.

The lower wishbone A-arm is anchored by a front subframe wîth a square-tube design. This design improves lateral rigidity and reduces the amount of vibration and road noise reaching the passenger compartment.

The five-link rear suspension features a trailing link, two longitudinal links and an upper A-arm. This suspension design permits the wheels to react independently when the car encounters a rough road surface. Anti-roll bars (25.5mm front/11.5mm rear) and gas-filled shock absorbers in both front and rear further enhance Sonata handling characteristics without sacrificing ride quality.

The Quality is Designed-In


The midsize Sonata is the product of extensive research, during which Hyundai engineers benchmarked some of the world's finest automobiles, and then used state-of-the-art supercomputer analyses to design and manufacturer a world-class midsize sedan. (concept carz)

The quality begins wîth the Sonata's rigid unibody structure, which was developed wîth the use of sophisticated supercomputer-aided design and manufacturing (CAD/CAM) tools. Sonatas are assembled at Hyundai's $1.25 billion Asan Assembly Plant, located 30 miles southwest of Seoul, South Korea.

Transmission Choices


A smooth-shifting five-speed manual transmission is standard equipment on the Sonata. Hyundai also offers an optional electronically controlled, 4-speed automatic transmission wîth Shiftronic manual control. The 4-speed Shiftronic automatic transmission represents yet another technological advancement for Hyundai and is standard equipment on all V6-equipped Sonata models.

The automatic transmission is an electronically controlled four-speed featuring a lock-up torque converter and overdrive. Shift quality is smooth, precise and unobtrusive and the automatic transaxle is controlled by a computer chip that uses 'fuzzy logic' technology. In addition, using the Shiftronic manual override feature, the driver can manually select the gear of choice. In normal driving, the Sonata is smooth and refined, yet it's highly competent when driven hard.

Thanks to power-assisted rack-and-pinion §teering, the Sonata's §teering is responsive and predictable, giving the driver a sense of confidence and control.

The Sonata also is exceptionally quiet. In designing the Sonata, Hyundai engineers used advanced supercomputer simulations to achieve impressive reductions in noise, vibration and harshness (NVH).

Wheels & Tires


Sonata GL models are fitted wîth 15-inch all-season radial tires mounted on 15 x 6.0-inch steel wheels wîth full wheel covers. Sonata GLS and LX models are equipped wîth handsome 16 x 6.0-inch alloy wheels fitted wîth all-season P205/60HR-16 high-performance steel-belted radial tires.

Four-wheel disc brakes are standard on all Sonata models. A sophisticated four-channel anti-lock brake system (ABS) is available on Sonata GL, GLS and LX. ABS wîth with electronic traction control is available on GLS and LX models.

World-Class Safety Features


The 2005 Hyundai Sonata offers such advanced safety features as driver and passenger front airbags, front seat-mounted side-impact airbags and automatic front safety belt pretensioners wîth load limiters. The Sonata's safety story begins wîth the vehicle's basic structure - a highly rigid unibody structure designed as a steel safety cell that helps protect occupants from crash forces in front, rear and side impacts.

Key structural components are reinforced wîth high-strength steel. Crumple zones in the front and rear absorb impact and deform in a predetermined manner, dissipating crash energy while protecting the driver and passengers. Additional side-impact protection is afforded by high-strength steel beams in the doors.

The Sonata is equipped wîth dual front supplemental airbags, as well as side-impact airbags, which are mounted in the sides of the front seats. Satellite sensors for the side-impact airbags are located just outboard of the front seats.

The Sonata also offers the high-tech Hyundai Passenger Presence Detection system, which prevents the front passenger airbag from deploying if the seat is empty. The passenger presence system reduces crash damage costs by eliminating unnecessary passenger side airbag deployment.

Advanced technology also is incorporated in the Sonata's seatbelts. The Sonata's seatbelt pretensioners automatically remove slack from front safety belts at the onset of a collision. This limits the occupant's forward movement and it also helps position them optimally for airbag deployment.

A single, highly advanced sensor located under the center console controls the front airbags and the seatbelt pretensioners. Additional interior safety enhancements include Sonata's childproof rear door locks, adjustable rear seat headrest and a three-point safety restraint in the rear middle position. The child safety restraint system featuring LATCH (lower anchors and tethers for children) is also standard.

America's Best Warranty


Únderscoring the Sonata's value leadership in the midsize §egmènt is its -leading assurance package, the Hyundai Advantage, America's Best Warranty. With this package, Hyundai demonstrates its confidence in the quality of its products by providing warranty coverage exceeding that found on cars costing twice or even three times as much.

The Sonata, like all 2005 Hyundai models, is backed by limited bumper-to-bumper coverage for five years or 60,000 miles. Hyundai also provides original Sonata owners wîth limited powertrain coverage for 10 years or 100,000 miles. Even if the car is sold, Hyundai still backs the Sonata's powertrain for five years or 60,000 miles.

Sonata buyers also receive 24-hour roadside assistance coverage at no extra charge for five full years (no mileage limit). The warranty includes emergency towing, lockout service and limited coverage for trip-interruption expenses. In addition, Hyundai backs Sonata wîth corrosion coverage for five years or 100,000 miles.

Hyundai Motor America, headquartered in Fountain Valley, Calif., is a subsidiary of Hyundai Motor Co. of Korea. Hyundai cars and sport utility vehicles are distributed throughout the Únited States by Hyundai Motor America and are sold and serviced through more than 640 dealerships nationwide.
