New Car Assessment Programs (NCAPs) are safety performance assessment programs that evaluate new automobile designs for their safety features. These programs aim to provide consumers with information about the safety of vehicles through crash tests and other evaluations. Here’s a detailed explanation of NCAPs and their significance:
Key Features of NCAPs
- Safety Ratings: NCAPs typically use a star rating system, ranging from one to five stars, to indicate vehicles’ safety levels. Higher star ratings represent better safety performance.
- Assessment Areas: NCAPs evaluate several aspects of vehicle safety, including:
- Adult Occupant Protection: How well the car protects adult passengers in various crash scenarios.
- Child Occupant Protection: The safety of child passengers, including the effectiveness of child restraint systems.
- Vulnerable Road User Protection: The car’s ability to protect pedestrians and cyclists in the event of a collision.
- Safety Assist: The presence and effectiveness of advanced driver assistance systems (ADAS) like automatic emergency braking, lane-keeping assist, and more.
Purpose of NCAPs
NCAPs are designed to:
- Improve Vehicle Safety: By setting high safety standards and conducting rigorous tests, NCAPs encourage manufacturers to enhance the safety features of their vehicles.
- Inform Consumers: NCAPs provide consumers with clear, independent information about the safety performance of new cars, helping them make informed purchasing decisions.
- Promote Innovation: By continuously updating their testing protocols, NCAPs drive innovation in automotive safety technologies.

Common Load Cases in NCAP Testing
NCAPs use various load cases to evaluate vehicle safety:
- Frontal Impact: A head-on collision with another vehicle or solid object is simulated.
- Side Impact: Evaluates protection in a side collision using a moving barrier.
- Pole Impact: Simulates a vehicle crashing sideways into a narrow object like a tree or pole.
- Rear Impact (Whiplash): Measures the risk of whiplash injuries in a rear-end collision.
- Pedestrian Protection: Assesses the vehicle’s design to minimize injuries to pedestrians.
- Rollover: The vehicle’s structural integrity and safety systems are evaluated in a rollover[1][2].
Euro NCAP Load Cases
Euro NCAP uses various load cases to evaluate vehicle safety. These load cases simulate different types of collisions and scenarios to assess how well a vehicle can protect its occupants and other road users. Here are the main load cases used by Euro NCAP:
- Frontal Impact
- Offset Deformable Barrier (ODB): The vehicle is driven into a deformable barrier at 64 km/h with a 40% overlap. This test simulates a head-on collision with another vehicle.
- Full Width Rigid Barrier (FWRB): The vehicle is driven into a rigid barrier at 50 km/h with full width. This test assesses the protection offered to occupants in a full-width frontal collision.
- Side Impact
- Mobile Progressive Deformable Barrier (MPDB): A deformable barrier is driven into the side of the stationary vehicle at 60 km/h. This test evaluates the protection offered to occupants in a side collision.
- Side Pole Impact: The vehicle is propelled sideways into a rigid pole at 32 km/h. This test simulates a vehicle crashing sideways into a narrow object like a tree or pole.
- Rear Impact (Whiplash)
- Whiplash Test: This test measures the risk of whiplash injuries to occupants in the event of a rear-end collision. It assesses the design and effectiveness of head restraints and seats.
- Pedestrian Protection
- Head Impact: Tests the impact of a pedestrian’s head on the bonnet of the vehicle.
- Upper Leg Impact: Evaluates the impact on a pedestrian’s upper leg.
- Lower Leg Impact: Assesses the impact on a pedestrian’s lower leg.
- Vulnerable Road User Protection
- AEB Pedestrian: Tests the vehicle’s automatic emergency braking system to detect and avoid pedestrians.
- AEB Cyclist: Evaluates the vehicle’s ability to detect and avoid cyclists.
- Safety Assist
- AEB Car-to-Car: Tests the vehicle’s automatic emergency braking system to detect and avoid collisions with other vehicles.
- Lane Support Systems: Assesses the effectiveness of lane-keeping assist and lane departure warning systems.
- Speed Assistance: Evaluates the vehicle’s speed assistance systems, including intelligent speed adaptation.
These load cases are designed to provide a comprehensive assessment of a vehicle’s safety performance in various real-world scenarios. Euro NCAP continuously updates its testing protocols to reflect advancements in automotive technology and safety standards[3].
