The EC6 line-up will feature a range-topping Performance version that uses two electric motors: a 160kW permanent magnet motor at the front axle and a 240kW induction unit at the rear. These will combine to offer a 0-62mph time of 4.7 secs, while its 110kWh battery will offer a range of more than 370 miles.
The EC6 uses similar frontal stying to the ES6 and larger ES8 SUVs, but has a more sharply raked coupé roofline at the rear. It also features a large panoramic glass roof. As with other Nio models, its spacious interior is dominated by a large portrait-oriented touchscreen mounted in the centre of the dashboard.
