Details and also Review of Hyundai Sonata Hybrid Automobile

[ad_1]
The Hyundai Sonata Hybrid, anticipated to hit dealerships later the following 12 months, is actually the South Korean company’s very first hybrid in the US marketplace. Apparently, Hyundai took its time, scrutinized the hybrid competition, along with attempted to outdo it in each and every respect. At a price beneath $26,000, Hyundai has developed a mainstream mid-size hybrid sedan that delivers real competitors for the purpose of class-leading fuel economic system. Hyundai expects the Sonata Hybrid to achieve 37 miles per gallon in the city plus 39 mpg to the highway.

Because the motor is synced directly towards the transmission, a clutch latches to and even unlatches from your gasoline-fed two.4-liter inline-four with 166 horsepower and 154 pound-feet of torque on tap (also revised somewhat from before within the yr). As you’d anticipate from a hybrid, the Atkinson-cycle variant from Hyundai’s Theta II family members is optimized intended for maximum efficiency. Ultimate combined performance figures are 206 horsepower and also 193 pound-feet of torque.

Hyundai engineers say the lithium-polymer batteries can tolerate tens of 1000s of charge cycles, with out getting to use a liquid-cooling method. According to W. C Yang, president of your Hyundai R&D Center, the Sonata Hybrid batteries should supply “300,000 miles with less than 10 percent reduction in efficiency . that’s purely from an engineering point of view, not a warranty point of view.” Hyundai currently delivers a 100,000 mile/10 yr powertrain warranty inside the U.S. marketplace.

Also enhancing highway mileage is actually an Atkinson-cycle version from the 2.4 Theta II engine, determined by the standard 2.4-liter engine in the Sonata, but recalibrated to run around the Atkinson cycle, a common way of improving the efficiency of engines used in hybrids. A fair amount of low-end torque is definitely sacrificed in the Atkinson conversion, but that is actually made up by the addition of torque in the electric motor. Combined, the engine along with electric motor generate 209 hp and also 195 lb-ft of torque, compared to 198 hp/184 lb-ft in the two.4-liter version standard in the Sonata.

The multi-disc clutch pack sits inside the motor and is certainly used to decouple the two.4-liter engine for idle/stop and also electric-drive modes. By allowing higher EV-only speeds, the clutch plays a big part inside the Sonata’s highway fuel efficiency. With a 17.2-gallon fuel tank, the Sonata Hybrid has a theoretical range of 766 miles.
