Spanish layman's summary:
Datos de la NHTSA (2010–2025) muestran que el cabeceo en choques frontales varía según el vehículo. El análisis mDTW reveló 4 grupos cinéticos según altura de CG y diseño EV/híbrido. Estos diseños reducen o invierten el cabeceo, desafiando los sistemas de retención actuales.
English layman's summary:
NHTSA crash data (2010–2025) shows vehicle pitch during frontal impacts varies by fleet architecture. mDTW clustering revealed four distinct kinematic groups, driven by CG height and EV/hybrid layouts. These EV designs reduce or reverse nose-down pitch, challenging current restraint systems.
