Compare the2025 Hyundai Elantra NVS 2025 Audi S3

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 S3 doesn’t offer a back seat reminder.

With its standard Forward Collision-Avoidance Assist, the Hyundai Elantra N is better at preventing collisions with pedestrians than the Audi S3, according to the Insurance Institute for Highway Safety:

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 S3 doesn’t offer a driver alert monitor.

Both the Elantra N and the S3 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The Hyundai Elantra N (Built after October 2024) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The S3 is not even a standard “Top Safety Pick” for 2025.

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 S3’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 S3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the S3 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. Hyundai will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the S3.

There are almost 3 times as many Hyundai dealers as there are Audi dealers, which makes it much easier should you ever need service under the Elantra N’s warranty.
