Small overlap front

The small overlap front evaluation consists of a driver-side and a passenger-side component. If the results of the two evaluations differ, then the combined small overlap rating is equal to the lower rating.

Driver-side

Rating applies to 2024 models

Tested vehicle: 2024 Honda Prologue EX 4-door 4wd

The Honda Prologue, an all-electric SUV, was introduced in the 2024 model year.

Driver restraints and dummy kinematics

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 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.

Passenger restraints and dummy kinematics The dummy’s head barely contacted the right side of the frontal airbag before moving into the gap between the frontal and side curtain airbags, leaving the head vulnerable to contact with forward structure. The inflated side curtain airbag has sufficient forward coverage to protect the head from contact with side structure and outside objects.

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

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger’s survival space was maintained well.

The dummy's head barely contacted the frontal airbag before moving into the gap in coverage between the frontal and side curtain airbags.

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

View of the vehicle after the crash showing the airbags and damage to the occupant compartment.

The rear passenger dummy's head approached the front seatback, which increases the risk of head injuries.

Rear passenger dummy injury values indicate a low risk of injury to the head or neck and a moderate risk of injury to the chest. During the crash, the shoulder belt remained in an ideal position on the dummy’s chest.

The rear passenger dummy's lap belt remained in the ideal position on the pelvis.

Overall rating
Distance at which headlights provide at least 5 lux illumination:

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

The low beams created some glare.

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

High-beam assist compensates for some limitations of this vehicle's low beams on the sharp right curve.
