Frequently Asked Questions

Q: Why aren’t EC6/EC7 sold in Europe?

NIO prioritized sedans (ET5, ET7) and conventional SUVs (ES6, EL8) for European launch. Coupé SUVs may come later.

Q: Is the EC6 just a restyled ES6?

Essentially yes—same platform and technology with a sportier roofline. Think BMW X3 vs X4.

Q: How much headroom do you lose?

Typically 1-2 inches in rear seats due to sloping roof. Most adults still fit comfortably.
