Specs on the new Kia Niro EV have been released, listed here is all what the powertrain is like:
"As far as the Niro EV is concerned, it comes with 201 hp and a near-instant torque of 255 Nm (188 lb-ft). It's enough electric punch for a 0 to 62 mph (100 km/h) run in 7.8 seconds and a top speed of 104 mph (167 km/h). The motor gets its necessary juice from a lithium-ion polymer battery with a capacity of 64.8 kWh. A full charge is estimated to last for 287 miles (463 km) in the WLTP cycle. Using a DC rapid charger will replenish the battery from 10 to 80 percent in around 43 minutes. With the second-gen model, owners will take advantage of bidirectional charging, but only for devices and at up to 3 kWh.

The Niro EV is more practical than its predecessor since it has gained a front trunk that can store 20 liters. Not only that, but the rear cargo area can now swallow 475 liters, representing a 24-liter increase over the model it replaces. Should you want the crossover with a combustion engine, the Niro HEV has a 451-liter volume while the PHEV is the least practical, at only 348 liters."
