Small overlap front: driver-side
Rating applies to 2017-25 models built after June 2017
Tested vehicle: 2017 Lexus IS 200t 4-door
The Lexus IS was redesigned for the 2014 model year. Beginning with the 2017 model year, the front-end structure was reinforced and the driver door, lower hinge pillar, and sill were modified to improve occupant protection in driver-side small overlap frontal crashes.
Beginning with 2017 models built after June 2017, the front-end structure was modified again and backing material in the footwell was added or changed to further improve occupant protection in driver-side small overlap crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Action shot taken during the small overlap frontal crash test of the 2017 Lexus IS built after June 2017.
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 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.
Forces on the left lower leg were just high enough to contribute to a moderate risk of injury.

Low beams
On the straightaway, visibility was fair on the right side of the road and inadequate on the left side. On curves, visibility was fair on both right curves and inadequate on both left curves.
The low beams never exceeded glare limits.
High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was fair on the gradual left and gradual right curves and inadequate on the sharp right and sharp left curves.
High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on the gradual right curve.
