2019 Chevy Impala: Unpacking the Safety Ratings for Peace of Mind

The Chevrolet Impala, a full-size sedan, underwent a significant redesign for the 2014 model year, and the 2019 model continues to offer the safety enhancements introduced in subsequent years. For those considering a 2019 Chevy Impala, understanding its safety performance is paramount. This comprehensive guide delves into the Insurance Institute for Highway Safety (IIHS) crash test ratings for the 2019 Chevy Impala, providing a detailed analysis to help you make an informed decision.

Small Overlap Front Crash Test: Driver-Side Evaluation

The small overlap front crash test simulates a collision where just the front corner of the vehicle impacts another vehicle or a solid object. This is a particularly challenging test, and the 2019 Chevy Impala performed admirably.

Evaluation criteria Rating
Structure and safety cage Acceptable (A)
Driver injury measures
Head/neck Good (G)
Chest Good (G)
Hip/thigh Good (G)
Lower leg/foot Good (G)
Driver restraints and dummy kinematics Acceptable (A)

The 2019 Chevy Impala achieved an “Acceptable” rating in the small overlap front crash test. The structure and safety cage held up reasonably well, earning an “Acceptable” rating. Crucially, driver injury measures for the head/neck, chest, hip/thigh, and lower leg/foot were all rated “Good,” the highest possible rating.

However, the “Driver restraints and dummy kinematics” were also rated “Acceptable”. The IIHS noted that during the test, the dummy’s head contacted the frontal airbag but then slid off to the left. This movement left the head potentially vulnerable to impact with structural elements. Despite this, the side curtain airbag deployed effectively, offering sufficient forward coverage to protect the head from side structure and external objects. The side torso airbag also functioned as intended.

Overall evaluation Good (G)
Curb weight 3,745 lbs
Peak force 16,836 lbs
Strength-to-weight ratio 4.50

The 2019 Chevy Impala earned a “Good” rating in roof strength. With a strength-to-weight ratio of 4.50, the roof can withstand over four times the vehicle’s weight, indicating robust rollover protection.

Head Restraints & Seats Evaluation

This evaluation assesses the effectiveness of head restraints and seats in preventing neck injuries in rear-end collisions.

Overall evaluation Good (G)
Dynamic rating Good (G)
Seat/head restraint geometry Good (G)

The 2019 Chevy Impala with power leather seats received a “Good” overall rating for head restraints and seats. Both dynamic rating and seat/head restraint geometry were rated “Good,” indicating effective protection against whiplash injuries.

Technical measurements for head restraints and seats are:

Headlights Evaluation

Headlight performance is crucial for nighttime driving safety. The IIHS tested two headlight variations on the 2019 Chevy Impala.

Premier Trim Headlights (HID Projector)

Evaluation criteria Rating
Low-beam headlight type HID projector
High-beam headlight type HID projector
Curve-adaptive? No
High-beam assist? No
Overall rating Poor (P)

The Premier trim’s HID projector headlights received a “Poor” overall rating. Low beam visibility was inadequate on straightaways and curves, and high beam visibility was also rated as fair to inadequate.

Technical measurements for Premier trim headlights:

LOW BEAMS Average minimum useful illumination distance (5 lux) Amount glare exceeded threshold
Straightaway right edge 76.0 m None
Straightaway left edge 42.5 m None

The headlight performance is a notable area of weakness for the 2019 Chevy Impala across all trims.

Front Crash Prevention: Vehicle-to-Vehicle Evaluation

The 2019 Chevy Impala offers optional front crash prevention systems.

Optional Forward Automatic Braking (Premier Confidence Package)

Overall evaluation Superior
Superior with optional equipment

When equipped with the optional Forward Automatic Braking system (part of the Premier Confidence Package), the 2019 Chevy Impala earns a “Superior” rating for front crash prevention. The system meets forward collision warning requirements and successfully avoided a collision in the 12 mph test and reduced impact speed by 10 mph in the 25 mph test.

Optional Forward Collision Alert (Driver Confidence Package)

Overall evaluation Basic
Basic with optional equipment

With the optional Forward Collision Alert system (available in the Driver Confidence Package), the 2019 Chevy Impala receives a “Basic” rating. This system provides forward collision warnings but does not include autobrake functionality.

Child Seat Anchors (LATCH) Evaluation

The LATCH system (Lower Anchors and Tethers for CHildren) is evaluated for ease of use.

Evaluation criteria Rating
Overall evaluation Acceptable (A)
Vehicle trim 1LS
Seat type cloth

The 2019 Chevy Impala received an “Acceptable” rating for child seat anchors. It has two rear seating positions with complete LATCH hardware and an additional position with a tether anchor and the ability to borrow lower anchors. The lower anchors were noted to be deep in the seat, and maneuvering around anchors in certain positions was difficult.

Details by seating position

Position Rating
1
Tether anchor Easy-to-find location, no confusion
Lower anchors Too deep, easy to attach, easy to maneuver
2
Tether anchor Easy-to-find location, no confusion
Lower anchors 1 dedicated, 1 borrowed from seat 3, too deep, easy to attach, difficult to maneuver

Conclusion: Overall Safety Assessment of the 2019 Chevy Impala

The 2019 Chevy Impala demonstrates a strong overall safety performance in IIHS crash tests. It earned “Good” ratings in moderate overlap front, side, roof strength, and head restraints & seats evaluations. The small overlap front test resulted in an “Acceptable” rating, primarily due to airbag slippage, although injury measures remained good. A significant area for improvement is headlight performance, which was rated “Poor” across all trims. Optional front crash prevention systems are available, with the Forward Automatic Braking system earning a “Superior” rating. Child seat LATCH anchors are rated “Acceptable,” with some ease-of-use considerations.

For potential buyers of a 2019 Chevy Impala, these safety ratings provide valuable insights. While the vehicle offers robust crash protection in most areas, the “Poor” headlight rating should be considered, especially for drivers who frequently drive at night. Choosing a trim with optional front crash prevention can significantly enhance safety. Overall, the 2019 Chevy Impala is a reasonably safe vehicle in its class, balancing strong crash test results with some areas needing attention.
