2011 Hyundai Sonata Hybrid Review:
Pros: The 2011 Hyundai Sonata Hybrid uses lithium polymer batteries for
its electric propulsion system. Its cabin tech suite features the most
responsive interface we've seen, with very solid navigation, phone, and
audio systems.
Cons: The navigation system only shows 2D maps, and the various hybrid screens don't show much actual fuel economy data.
The 2011 Hyundai Sonata Hybrid makes for a high-tech cruiser. It's a comfortable car with impressive body styling and useful cabin electronics.
The 2011 Hyundai Sonata Hybrid and 2011 Kia Optima Hybrid may not be twins, but they share much of the same DNA. The sheet metal looks different, but under the skin they are virtually the same. Built on the same platforms, both the Sonata and Optima Hybrids use a 2.4-liter Atkinson cycle four-cylinder engine, complemented by an electric drive system using a 34-kilowatt lithium polymer battery pack. Both offer similar cabin electronics, a flash-memory-based navigation system with traffic and weather, solid MP3 playback, and a Bluetooth phone system. They even use the same Infinity audio systems.
