Furthermore, Hyundai claims that the latest generation Sonata Hybrid could consume the fuel reaches 39 miles per gallon on the highway road, while 37 miles a gallon on the road for a lot of obstacles, such as urban roads. This car is claimed to be 40 percent more efficient than the previous generation. They are four-cylinder engine has been recalibrated for 2012 and is now even more fuel efficient is better to provide the best in class fuel economy. In fact, in 2012 Sonata GDI led the entire middle segment (non hybrid) in the city (24 mpg) highway (35 mpg) and combined (28 mpg) fuel economy, while the Sonata 2.0T is now achieving 34 mpg highway, up from 33 mpg in model year 2011.
Standard Blue Link - safety, health telematics and infotainment systems. Sonata GDI now leads the entire medium car segment (non-hybrid) on all fuel economy numbers - city, highway and combined With a choice of 2.4 liter I4 engine native GDI, 2.0-liter I4 turbo engine or a 40 mpg hybrid, the Sonata offers a variety of fuel-efficient powertrains Three-piece panoramic sunroof is now standard on the Sonata Limited The new seven-inch touch screen navigation with HD Radio Technology Rear backup camera is available in the SE with Sunroof and Navigation Package.
Sonata was launched with the original GDI Theta II 2.4-liter four-cylinder engine with the fuel system Direct-Injection Gasoline delivery (GDI), which contributes to improved fuel efficiency and lower emissions. The road is shorter, more direct than the fuel delivery, allowing for greater control of fuel mixture at the optimum time, thus increasing efficiency. Fuel is injected by a camshaft-driven pump, high pressure operating at pressures up to 2175 psi. Direct injection also uses a higher compression ratio of 11.3:1 normal for increased power. The pistons are "dished" to increase the efficiency of combustion in the cylinder. This powerplant gives the best fuel economy in its class and best-in-class four-cylinder horsepower and torque in its class.
Sonata provides an impressive lead segment city/35 mpg 24 mpg fuel economy rating highway/28 combined with either a manual six-speed automatic transmission with SHIFTRONIC ®. Horsepower and torque ratings for the Theta II GDI is 198 horsepower and 184 lb.-ft. torque. In SE trim, which includes standard dual exhaust, engine delivering 200 horsepower and 186 lb.-ft. torque. This high-tech, all-aluminum, 16-valve engine features Continuously Variable Valve Timing Ganda (DCVVT) and Variable Induction System (VIS) for better engine breathing. A version of this engine also meets Partial Zero Emission Vehicle (PZEV) standards.
With the 2.0-liter Theta II turbocharged GDI, 2012 Sonata offers an unprecedented combination of segment leading fuel efficiency and power - with a rating of 34 mpg highway, 274 horsepower at 6,000 rpm and 269 lb-ft of torque from 1800-4500 rpm with regular fuel. The 2.0T Sonata provides an outstanding 22 mpg city and 34 mpg highway. Hyundai's turbocharged engine equipped with twin-scroll turbocharger that when combined with the GDI system results in instantaneous power delivery. 2.0T engine is available in SE and Limited trim levels, the 2.0T SE adding a temperature control system is fully automatic upgrade, and the Limited adds 18-inch hyper silver alloy wheels SE, dual exhaust, and steering wheel-mounted paddle shifters.
Heart of the technological breakthroughs of 2012 Sonata Hybrid Hybrid's incredible Blue Drive lithium polymer battery pack. Simple hybrid powertrain Hard Blue with decoupling the engine, significantly reducing the amount of energy required to maintain highway speeds, so the estimated outstanding 40 mpg highway rating of fuel, the best of any mid-size hybrid sedan on the market.
Hyundai Sonata's commitment to create a highly efficient fuel continues with a six-speed automatic transmission with manual control SHIFTRONIC or transaxle six-speed manual standard.
When it comes to transmissions, gears more clearly better. The addition of the sixth gear enables closer spacing between gear ratios providing a better balance of performance and fuel economy while the overall width of the gear ratio helps deliver strong acceleration.
The gearbox has three planetary gearsets and a unique flat torque converter which shortens the overall length by 0.47-inch unit. Four different pinion improve durability and further minimize size.
The Hyundai Sonata is one of only two cars on the market That both have received a Top Safety Pick designation from the Insurance Institute for Highway Safety and a five-star overall safety rating from the federal government under its new crash-test procedures.
