A Nio EC6 electric SUV-coupe was involved in a high-speed crash on December 1 in a suburban area of Shanghai, during which the vehicle’s rear section split from the cabin after colliding with a concrete roadside barrier. According to a statement issued shortly after the crash, the vehicle’s safety system immediately reported the incident; Nio staff rushed to the scene and transported the occupants to the hospital. Both individuals survived without life-threatening injuries.

According to the manufacturer’s account, the EC6 was not using its driver-assist system at the time of the accident. Once the collision occurred, the car’s doors unlocked automatically and the handles deployed, allowing the occupants to exit. The battery pack reportedly did not catch fire or exhibit any sign of thermal runaway or safety risk. Local police are investigating the cause of the accident.

The EC6 is a mid-size battery electric coupe-SUV produced in China since 2020. The latest 2025 model year offers dual-motor all-wheel-drive, delivering 360 kW of combined power and a CLTC-rated range of up to 630 kilometres using a 100 kWh battery pack.

Data provided by the automaker suggests that in this crash. However, the rear of the vehicle sustained structural failure after impacting a “knife-edge” concrete barrier at high speed, while the occupant cell remained intact. According to a technical account of the collision, the barrier’s narrow top edge, only about 12 centimetres wide, created extremely high local pressure, causing a so-called “cutting-type” failure concentrated at the C-pillar and rear floor. Despite severe damage to the vehicle’s rear, the passenger compartment showed no signs of deformation. Occupants reportedly could open the doors and exit the vehicle unaided. On-site images reportedly show a driver able to sit on the door-frame, underscoring that the cabin’s structural integrity held under extreme conditions.

The aftermath supports the view that the EC6’s steel-aluminium mixed body structure and high-strength safety cell preserved occupant integrity even in this rare extreme crash scenario. The absence of fire or battery failure suggests that the vehicle’s battery protection and passive safety design performed as intended.

While this singular incident does not automatically reflect on overall vehicle quality or design robustness across all crash modes, it does provide a real-world data point confirming that under this extreme localised barrier impact, the EC6’s safety architecture maintained core safety standards.

at least can open door, unlikely xiaomi after crash door cannot buka

and the passenger is damn lucky, the bonnet already crash into half

I thought EV door can't be open during accident

Inb4, MY Consumer mindset: RV > Safety

amazing . no fire.

Autobots transform.

So weird that it was cut.
At least didn't caught fire

This model EV must buy, safety feature +1. Car auto split in half lets driver & passenger escape safely, Tesla must learn

This is the problem with interchangeable battery system

The battery cannot be a structure members of the car
So failure point risk is higher

How fast until the cement block break like that?

Why NIO can provide Battery-as-a-service model to but when Perodua Q-VE do it, all condemn Perodua

Anneh okay with BaaS style of P2 EV. The risk of battery obsoleteness/degradation is transferred to P2. All other automaker, buyer owns and carry the risk of battery degradation/obsoleteness/lowering the car rezale value down

Those staying in condo is woso same what? Forever pay subscription/maintenance fee…

ini...transform halfway...

10 replies nobody mentioned woman driver

i'm disappointed, k

hggggnhhhhnnnn

New EV secret function they dont want to tell user

Split into half for easy escape

Nio i thought is swap out the battery when you need to refuel/recharge :X

perodua also same? need to go to their station and swap out the battery when battery flat?

woman n young? :X

NIO sell full price, then offer BaaS option later. People see lower price option.

P2 offer BaaS straight away, so people calculate the end cost to be higher with battery leasing fee. 80k starting price is ridiculous.

It's a subscription fee
