Small overlap front: driver-side

Rating applies to 2017-25 models

Tested vehicle: 2017 Audi A4 2.0T Premium 4-door 2wd

The Audi A4 was redesigned for the 2017 model year. Driver-side small overlap frontal ratings apply to the Audi A4 4-door sedan (tested) and to the structurally similar Audi A4 allroad wagon, also redesigned for the 2017 model year, and to the Audi A5 Sportback 4-door hatchback, introduced in the 2018 model year.

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

On the straightaway, visibility was good on the left side of the road and fair on the right side. On curves, visibility was good in all 4 tests.

The low beams created some glare.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and on both left curves.
