2014 Nissan LEAF IIHS and NHTSA Crash Tests

The premiere battery electric performs poorly in the IIHS Small overlap.

2014 Nissan LEAF performs poorly in the IIHS Small Overlap Crash Test with significant intrusion leaving little survival space for the dummy, meaning likely knee and leg injuries. The LEAF earned a poor rating.



The 2015 Nissan LEAF safety features includes front, side, and side curtain airbags with front seat belt sensors and occupant classification sensor, three-point ALR/ELR seat belts (driver's seat ELR only) with pretensioners and load limiters, child seat upper tether anchor, LATCH (Lower Anchors and Tethers for CHildren) system and child safety rear door locks standard. Vehicle Dynamic Control (VDC) and Traction Control System (TCS) is also standard on all LEAF models.



Back in 2011, the LEAF was one of the first mainstream battery electric models to undergo IIHS crash test evaluations. The 2011 model earned top ratings in the moderate overlap front, side, head restraint and roof-strength evaluations. That's still the case with the 2014 version.



The LEAF IIHS small overlap crash test revealed numerous design shortcomings. Besides the A-pillar failing completely, the LEAF had as much as 16 inches of intrusion in the lower occupant compartment and 14 inches in the upper occupant compartment. The instrument panel, parking brake pedal and steering column were all pushed back toward the driver. Injuries to the left knee and left lower leg would be likely in a crash of this severity, and injuries to the left thigh would be possible.



IIHS’ Additional Precautions When Testing HEVs, PHEVs, and BEVs



When testing hybrid or electric models, IIHS follows special safety protocols. Post crash, technicians check for high voltage and high temperature, which could lead to a potentially fatal electrical shock and/or fire. No one can touch the car until given the all-clear. Technicians wear safety gear, including eye protection, rubber boots and rubber gloves. They’re tethered at the waist to a long pole, which can be used to pull them away from the vehicle in an emergency. No issues with the batteries or electric systems were experienced in the Leaf tests.

Along with the pack longevity, I hope Nissan is working hard at correcting this problem ASAP.
