Sonata dials it up with a choice of two new and improved powertrains mated to a six-speed automatic gearbox. Gear selection is controlled by a new shift-by-wire selector that makes for safer, more precise and fool-proof gear changes and its smaller footprint clears up valuable space on the center console. This same push-button convenience is brought to the electronic parking brake which comes with auto-hold that allows the driver to remove his foot from the brake pedal during stops to relax the leg muscles while maintaining brake pressure.
