Compare the2026 Buick Encore GXVS 2026 Audi Q3

The Buick Encore GX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q3 doesn’t offer knee airbags.

Both the Encore GX and the Q3 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, rear cross-path warning and available around view monitors.

Buick’s powertrain warranty covers the Encore GX 1 year and 10,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

There are over 2 times as many Buick dealers as there are Audi dealers, which makes it much easier should you ever need service under the Encore GX’s warranty.
