In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Leaf are reminded to check the back seat if they opened the rear door before starting out. The Sonata Plug-In Hybrid doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Leaf has standard Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Sonata Plug-In Hybrid doesn’t offer backup collision prevention brakes.

The Leaf (except S) offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Sonata Plug-In Hybrid only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The Leaf (except S)’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Sonata Plug-In Hybrid doesn’t offer a driver alert monitor.

Both the Leaf and the Sonata Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, blind spot warning systems, rearview cameras, rear cross-path warning and available daytime running lights.

The Leaf SV/SL’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata Plug-In Hybrid’s 55 series tires.

The Leaf has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Sonata Plug-In Hybrid doesn’t offer vehicle monitored tire inflation.

The Nissan Leaf may be more efficient, handle and accelerate better because it weighs up to about 250 pounds less than the Hyundai Sonata Plug-In Hybrid.

The Leaf has a much larger cargo volume with its rear seat up than the Sonata Plug-In Hybrid (23.6 vs. 9.9 cubic feet).

To allow full utilization of available cargo room, the Leaf’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. Its intrusive beam hinge reduces the Sonata Plug-In Hybrid’s useful trunk space.

The Leaf’s standard rear seats fold to accommodate long and bulky cargo. The Sonata Plug-In Hybrid doesn’t offer folding rear seats, only a ski pass-through.

The Leaf SV/SL has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Sonata Plug-In Hybrid doesn’t offer a remote starting system.

To improve rear visibility by keeping the rear window clear, the Leaf has a standard rear wiper. The Sonata Plug-In Hybrid doesn’t offer a rear wiper.

Both the Leaf and the Sonata Plug-In Hybrid offer available heated front seats. The Leaf SL also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Sonata Plug-In Hybrid.
