The production version of the 2017 Chevrolet Bolt EV 200-mile electric car made its auto-show debut this morning in Detroit, after last week's global unveiling at the Consumer Electronics Show in Las Vegas.
But while the car was familiar, Chevy provided some eagerly sought information on the car's specifications.
The capacity of the Bolt EV's lithium-ion battery pack is 60 kilowatt-hours, and the output of the electric motor driving its front wheels is up to 150 kilowatts (200 horsepower).
The permanent-magnet traction motor is also rated at up to 266 lb-ft (360 Newton-meters) of torque.
And the combination will provide acceleration from 0 to 60 mph in less than 7 seconds, GM says.
For battery recharging, the Bolt EV's onboard charger operates at up to 7.2 kilowatts.
There's been much speculation on the capacity of the Bolt's lithium-ion flat battery pack, from as little as 53 kWh to more than 60 kWh.
The final 60-kWh statistic, however, is just about what's been expected for the pack, which uses liquid thermal conditioning to keep its operating temperature within the best range for long life.
The 960-pound battery is located under the cabin floor, stretching from side to side and from the front footwell to the back of the rear seat.
Using the built-in 7.2-kW charger, GM quotes a charging time of "50 miles in less than 2 hours" using a 240-Volt Level 2 charger. At the press conference, GM product chief Mark Reuss said a full recharge will be about 9 hours.
That doesn't address the time required for a full recharge, but may be more representative of how many Bolts will be used by their owners for daily transport.
The Bolt EV will also include an optional CCS fast-charging port, which GM says will provide "90 miles in 30 minutes," presumably on today's CCS charging stations, which have a maximum output of 50 kilowatts.
The EPA classifies the 2017 Bolt EV as a "small wagon," though most onlookers would call it a five-door hatchback.
Chevy gives the 2017 Bolt EV a target curb weight of 3580 pounds (1620 kg), "without two passengers" inside.
GM notes on its spec sheet that "EPA does not have a crossover category," although without any option mentioned for all-wheel drive, the Bolt would seem to lack one of the crucial qualifications for a crossover utility vehicle.
The company collaborated closely with battery maker LG Chem on development of the Bolt EV's powertrain.
While the car itself is assembled at Chevy's Orion Township plant in Michigan, its battery, motor, and drive unit are all manufactured in Inchon, South Korea.
