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 Elantra N are reminded to check the back seat if they opened the rear door before starting out. The S4 doesn’t offer a back seat reminder.

The Elantra N has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the S4’s blind spot costs extra.

To help make backing out of a parking space safer, the Elantra N has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Audi charges extra for Rear Cross-Traffic Assist on the S4.

The Elantra N’s 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 S4 doesn’t offer a driver alert monitor.

Both the Elantra N and the S4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

The S4 has not yet been evaluated by the IIHS for 2024.

The Elantra N comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The S4’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Hyundai’s powertrain warranty covers the Elantra N 6 years and 50,000 miles longer than Audi covers the S4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the S4 ends after only 4 years or 50,000 miles.

Hyundai pays for scheduled maintenance on the Elantra N for 3 years and 36,000 miles.
