BYD Datang EV Teardown Highlights Practical Chassis Engineering

A new Autohome teardown takes a close look beneath the BYD Datang EV 850 km flagship. The story matters because the Datang sits in a segment where buyers increasingly ask whether comfort features and long range are backed by serious engineering.

Autohome’s teardown describes steel exterior panels paired with plastic bumpers, an aluminum front crash beam, a reinforced water-tank frame, a steel full-frame front subframe and a front double-wishbone suspension using aluminum arms and knuckles.

What changed

The vehicle also uses BYD’s Yun Nian-A dual-chamber air suspension and variable damping. In practice, that gives the SUV a route to combine soft urban ride quality with firmer body control at speed or in corners.

At the rear, Autohome reports a bow-shaped steel crash beam, a full-frame steel rear subframe and a five-link independent suspension that uses robust components rather than the simplified layout critics often claim. The teardown also focuses on the second-generation Blade Battery.

EV InnoTech take

The Datang EV does not appear to chase exotic materials everywhere. Instead, the engineering story is selective: use aluminum where unsprung mass and energy absorption matter, steel where durability and repair cost matter, and spend on suspension hardware where owners can feel the difference.
