Compare the2025 Kia K5VS 2024 Audi A3

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 K5 are reminded to check the back seat if they opened the rear door before starting out. The A3 doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The K5 EX/GT1 has standard Parking Collision Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The A3 doesn’t offer automatic braking for stationary objects directly to the rear.

The K5 EX/GT1 has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The A3 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The K5 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 A3’s blind spot costs extra.

To help make backing out of a parking space safer, the K5 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 A3.

The K5’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 A3 doesn’t offer a driver alert monitor.

Both the K5 and the A3 have standard driver and passenger frontal airbags, front and rear 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, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

The K5 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The A3’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Kia’s powertrain warranty covers the K5 6 years and 50,000 miles longer than Audi covers the A3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A3 ends after only 4 years or 50,000 miles.

There are almost 3 times as many Kia dealers as there are Audi dealers, which makes it much easier should you ever need service under the K5’s warranty.

The design of the Kia K5 amounts to more than styling. The K5 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the A3 (.29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the K5 get better fuel mileage.

Because it has more passenger and cargo room, the EPA rates the K5 a Large car, while the A3 is rated a Subcompact.

The K5 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house.

The A3 doesn’t offer a remote starting system.

The K5 EX/GT1’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The A3 doesn’t offer an easy entry system.

Keyless Engine Start/Stop standard on the A3 only offers hands-free access for the ignition, none to unlock the car.

The K5’s sun-visors swivel front-to-side to block glare from the side windows. The A3’s visors are fixed into the windshield header.

Standard air-conditioned seats in the K5 EX/GT1 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The A3 doesn’t offer air-conditioned seats.

On extremely cold winter days, the K5’s optional (except LXS) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The A3 doesn’t offer a heated steering wheel.
