The Nio EC7 is a battery-powered mid-size luxury crossover SUV manufactured by Chinese electric car company Nio. It was announced on the Nio Day in late 2022 and first deliveries are scheduled for June 2023.^[1] The EC7 serves as the flagship coupe SUV.^[2]

The EC7 is a 5-door, 5-seater crossover SUV with a sporting roofline. It is a "crossover coupe" counterpart to the more boxy ES7. The car is offered with an option for a 150-kWh battery, available for all current Nio models. The EC7 is powered by a lithium-ion battery pack, which is swappable, just like the Nio ES8.^[3] The EC7 acts as a direct competitor to the Tesla Model X.

The EC7 generates 487 kW (653 hp), translating into a 0–100 km/h time of 3.8 seconds.^[4] This version uses a 300 kW induction motor in the rear and a 180 kW permanent magnet motor in the front.^[4] The EC7 is available with three lithium-ion battery pack options: 75 kWh, 100 kWh, and 150 kWh, officially expected to deliver a CLTC range of up to 490 km (305 miles), up to 635 km (395 miles), and 940 km (584 miles), respectively.^[3]

Nio claims that the EC7 has a drag coefficient of 0.23, which is the lowest ever for a production SUV as of 2023. The car features active air suspension, NOMI AI personal assistant, Nappa leather and intelligent fragrance system.^[5]
