Hyundai introduced its all-new 2011 Hyundai Sonata at the 2009 Los Angeles Auto Show. This marked 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. Hyundai Sonata is the second vehicle in Hyundai's 24/7 version 2.0 product initiative (seven new models in the next 24 months) following on the heels of the all-new Tucson. Production of Hyundai Sonata will begin in December 2009 at Hyundai's U.S. plant in Alabama with retail sales beginning in January 2010.
2011 Hyundai Sonata Midsize Sports Sedan
The new Sonata will launch with Hyundai's new Theta II GDI 2.4-liter four-cylinder engine with a Gasoline Direct-Injection (GDI) fuel delivery system, which contributes to improved fuel efficiency and lower emissions. Hyundai 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.
The Sonata 2.0T, as the car is officially named, is powered by a new 2.0-liter Theta II twin-scroll turbocharged gasoline direct-injection (GDI) engine that produces 274 horsepower at 6,000 rpm and 269 lb-ft of torque from 1800-4500 rpm with regular fuel. The engine is linked to a six-speed automatic transmission with SHIFTRONIC manual control that drives the front wheels. No performance figures were released but Hyundai did announce that the Sonata 2.0T will deliver an estimated 22 mpg (10.7lt/100km) city and 34 mpg (6.9lt/100km) highway.
The 2.0-liter twin-scroll turbo engine will be available on the Sonata SE and Limited trim level, with the Limited getting additional upgrades, including a panoramic sunroof, 18-inch "hyper" silver alloy wheels, dual exhaust system and steering wheel-mounted paddle shifters.
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. Hyundai 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 Hyundai Sonata extremely fuel efficient continues with a six-speed automatic transmission with SHIFTRONIC manual control or a standard six-speed manual transaxle. Hyundai's all-new six-speed automatic A6MF2 transaxle helps the company meet its goals of improving fuel efficiency and reducing emissions. Shifts are silky-smooth with an option of manual control through the SHIFTRONIC feature.
Developed over a four-year period, this new six-speed automatic is 26.4 pounds lighter than the five-speed it replaces. It also is 1.6 inches shorter and considerably simpler, having 62 fewer parts, which is a key to increased durability, lighter weight and lower cost. When it comes to transmissions, more gears are definitely better. The addition of a sixth gear enables closer spacing between gear ratios providing a better balance of performance and fuel economy while the wide overall gear ratio helps deliver strong acceleration.
All Sonatas have column-mounted, motor-driven electric power steering that adjusts instantly to changing driving conditions while improving fuel economy over a conventional steering system. A quick-ratio steering rack is used for crisp feel on turn-in. Hyundai Sonata's turning diameter of 35.8 feet is better than Camry, Accord, Altima, Fusion and Malibu.
One of the program targets for the 2011 Sonata engineering team was world-class power-to-weight ratio. Power-to-weight ratio pays dividends in both performance and fuel economy. Hyundai Sonata is rich in ultra-high-strength steel, leading to world-class body rigidity. The 2011 Hyundai Sonata is 25 percent stiffer in torsion and 19 percent stiffer in bending rigidity than its predecessor, yet it is lighter than many midsize sedans, also offering more interior room.
The 2011 Sonata is a smart combination of superior styling, performance, safety and fuel efficiency. What’s more, it’s an affordable midsize car, putting a luxurious and rewarding driving experience within reach of many. Make the 2011 Sonata a part of your future.
