All new 2011 Sonata can also be driven in all electric mode. Hyundai says that the Sonata Hybrid can cruise on all-electric at speed of up to 62 mph, and company's engineer indicated that the car might do even better. Hyundai did this by converting its 2.4-liter four-cylinder engine to the Atkinson Cycle and added a 40-horsepower electric motor, which is good for a combined 206 horsepower and 193 pound-feet of torque, but the main thing is the car's battery pack.

Instead of cull out the cheaper nickel-metal hydride cells, Hyundai's choice was costlier lithium-polymer cells with a total of 72 cells into the pack, which weighs a relatively 96 pounds.
