Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Volvo S40 was redesigned during the 2004 model year (the new design entered production in January 2004 and the earlier design, which is classified as a small car, remained in production into February 2004). Note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door. To assure that the S40 is the new design, look for vehicles manufactured in March 2004 or later.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the redesigned 2004 S40 in a 40 mph frontal offset crash test into a deformable barrier.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. After the dummy moved forward into the airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Volvo S40 was introduced in the 2000 model year and structurally modified beginning with 2002 models to improve occupant protection in frontal crashes.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the right tibia indicate that injuries to the lower leg would be possible. Head acceleration from the A-pillar hit was negligible.

Restraints and dummy kinematics

Dummy movement was reasonably well controlled. During rebound, the dummy's head tilted outward, brushed the A-pillar, and continued partway out the open side window.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
