EV Safety Benefits — Crumple Zones, Rollover Results, Vehicle Control
December 30th, 2018 by Zachary Shahan
Earlier this year, we published a free report on EV safety, The EV Safety Advantage. As we approach the end of the year, we’re publishing sections of that report as articles here on CleanTechnica.
In this section of the report, we roll through a handful of clear EV safety benefits, which help to explain electric cars’ better performance in the case of accidents and subsequent insurance claims. We also throw in more safety ratings and charts.
Note: Yes, we need to update the report to include Model 3 ratings, and we will do so once some more are published.
Optimal Crumple Zone
⇒ The absence of an engine in the front of the vehicle improves the crumple zone of EVs.
⇒ The centered location of battery packs vastly reduces the torque forces in a car accident.
⇒ In terms of frontal crash tests, EVs are comparable to high-end ICE vehicles.
Reduce Rollover Risk
⇒ 2% of crashes involve a rollover, but they cause 35% of deaths.
⇒ Large battery on the base lowers the center of gravity and reduces the rollover risk for EVs.
⇒ Tesla Model S achieves a record low 5.7% rollover likelihood in a single-vehicle crash, and Tesla Model X achieves the best rating among comparable SUVs.
Better Maneuverability and Control
⇒ Electric vehicles benefit from better dynamic stability due to a centered battery pack and electronic control of power and braking.
For Frontal Crash Ratings, EVs Perform at Least as well as Luxury ICE Vehicles
Rollovers Have a Higher Fatality Rate than Any other Kind of Crashes
EVs are Less Likely than ICE Vehicles — including Luxury and Most Popular Cars — to Roll over Due to Better Stability
Among SUVs, Tesla Model X is the Safest Car Ever Tested
⇒ Tesla Model X is the first SUV ever to get the top score in all of the component ratings, including rollover risk.
⇒ SUVs have a higher center of gravity and are more prone to roll over than a typical family sedan. But the EV model has a heavy battery pack at the bottom of the car, hence a much lower center of gravity than the typical SUV.
⇒ According to Tesla, NHTSA’s tests found that people inside a Model X have a 93% chance of walking away from an accident without serious injury — second highest on record behind the Tesla Model S.
