After the winter tests completed in New Zealand and extreme heat tests in Sanya of Hainan, Turpan of Xinjiang, and Chongqing in China, this time NIO took the ET7 for high-altitude testing to Tibet.
On the route from Shanghai and Lhasa, the altitude increases to about 5,000 meters, but since there is no internal combustion engine, performance of an electric car does not diminish.
Nonetheless, there are plenty of elements that require testing in various circumstances. For example, the air suspension must be double checked as the air pressure changes with altitude, which might affect its setting and ride comfort.
According to CnEVPost, NIO was testing also the steering system, braking system, EDS system, power cell system, cooling and heating of the passenger compartment, and overall vehicle NVH.
According to the latest rumors, the NIO ET7’s new drive units (180 kW permanent magnet in the front and 300 kW induction motor in the rear) will be used also in the current NIO models – ES8, ES6 and EC6. That makes economical sense, we guess, especially since the battery packs are already shared between the models.
NIO ET7 specs:
- 70 kWh battery – more than 500 km (311 miles) of NEDC range
- 100 kWh battery – more than 700 km (435 miles) of NEDC range
- 150 kWh battery option in the future will get more than 1,000 km (620 miles) of NEDC range
- 0-100 km/h (62 mph) in 3.9 seconds
- dual motor all-wheel drive
- system output of 480 kW and 850 Nm of torque
front motor (permanent magnet): 180 kW
rear motor (induction motor): 300 kW
NIO 2nd generation powertrain with SiC power electronics
- 100-0 km/h braking in 33.5 m, with Brembo brakes (standard)
- Cd of 0.208 (vs initially expected 0.23)
