Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the Elantra Sedan Value Edition/Eco/Sport/Limited’s trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Regal Sportback doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.


While driving with high beams on, sensitive light sensors standard on the Elantra Sedan Sport/Limited detect other vehicles which could be blinded and automatically switch to low beams. The Regal Sportback doesn’t offer automatic dimming high beams.

The Regal Sportback’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Elantra Sedan Limited’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Elantra Sedan Value Edition/Eco/Sport/Limited has standard extendable sun visors. The Regal Sportback doesn’t offer extendable visors.

The Elantra Sedan has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise.
