Spark achieved highest possible “good” scores in the IIHS’s moderate overlap front, side, roof strength and head restraints tests, and scored an “acceptable” in IIHS’s new small overlap test, designed to replicate what happens when the front corner of a vehicle strikes another vehicle or an object like a tree or a utility pole.
“Spark’s impressive performance in IIHS’s most stringent test yet demonstrates the intensive efforts of our global safety team to deliver big safety in a small package,” said Gay Kent, General Motors general director of Vehicle Safety and Crashworthiness. “Spark’s safety structure makes extensive use of high-strength and ultra-high-strength steels and its robust passenger protection package includes 10 standard air bags.”
Minicars present unique challenges when designing for crashworthiness. Spark’s relatively short wheelbase of 93.5 inches required the Spark team to strengthen the car’s front-end structure to better absorb and distribute impact energy around occupants. A cradle extension offers additional support in frontal collisions.
Lightweight, high-strength steels constitute more than 62 percent of Spark’s under body and 42 percent of its upper body. The car’s rigid door beams and H-shaped structure under the seating area are designed to enhance protection in side impacts, and its high-strength cross members are designed to help manage crush space in side impacts.
Spark’s roof bow and B-pillar also use high-strength steels to help preserve the occupant space in a rollover crash. Likewise, the high-strength rear rail is designed to help protect the fuel tank in side and rear impacts.
Spark’s driver and passenger front knee air bags are designed to reduce the risk of lower extremity injuries in frontal crashes. Further protection is provided by dual-stage frontal air bags, seat-mounted side air bags and side curtain air bags that extend over the front and rear seating rows.
Additional safety features include a rollover sensing system, three-point safety belts in all four seating positions, safety belt pretensioners in the front driver and passenger seats, the LATCH child seat attachment system, adjustable head restraints and collapsible steering column.
MIRA has extensive experience in providing test engineering services to the global automotive industry. With over 35 major test facilities, including a comprehensive set of safety laboratories - crash, impact simulation, pedestrian; vehicle and component environmental facilities; full scale aerodynamic wind tunnel; vehicle and component EMC (electromagnetic compatibility); component and structures test labs.
Our team of specialist test consultants, engineers and technicians provide our clients with hundreds of years of combined expertise in testing to regulations and standards, to client specific requirements and in the development of appropriate test procedures and methods.
Ongoing capital investment in major facilities and equipment to support our client base has seen the recent additions of a new EMC facility, a major upgrade to our vehicle Climatic Wind Tunnel (CWTOne) and a comprehensive battery test facility.
Research and development investment in new test methods and tools is also an important part of MIRA’s test engineering business. Recent R&D investment has resulted in the introduction of a new ‘non-destructive’ low ‘g’ test rig and associated test methods, which are now being used to support vehicle manufacturers with sensor development in rollover scenarios. Continued R&D investment has also led to an expansion of MIRA-Caepro’s Safety Development offering. The introduction of our new advanced FMVSS 201U/226 facility enables clients to assess the energy absorbing qualities of the interior trims of vehicles and test the performance of side windows and curtain airbags to ensure they meet FMVSS 226 requirements.
