Chevrolet has revealed more details about the production Bolt EV at the Detroit Auto Show, having whipped the covers off the car in Las Vegas last week. As well as talking about range and cost, GM CEO Mary Barra and Executive Vice President of Global Product Development Mark Reuss used NAIAS to shed light on the Bolt's slimline battery, power output and punchy performance.

Just like most production EVs, the Bolt uses a single, high-output motor to make progress. With 150 kW (200 hp) and 360 Nm of torque, Chevy's EV is good for a 0-60 mph (97 km/h) sprint of under seven seconds, putting it in the same sort of territory as hot hatches like the RenaultSport Clio and VW Polo GTi.

The motor draws its power from a 60 kWh battery pack, made up of 288 lithium-ion cells measuring up at 100 mm (3.9 in) high and 338 mm (13.1 in) wide, spanning the whole floor, from the front footwell to the back of the rear seats. Chevy has used a nickel-rich chemistry in the car's lithium-ion battery in an attempt to cut down on cooling hardware and to make sure the Bolt delivers peak performance regardless of the climate it's in.

One of our overriding memories from time spent in the Telsa Model S is the power of its regenerative braking system. Because the car harvests energy so aggressively when you lift off the accelerator, driving the big sedan almost becomes a one-pedal deal – something Chevrolet has aimed for with the Bolt, which it claims can come to full standstill without having drivers touch the brakes.

Don't worry if you're particularly attached to your brake pedal, because the Bolt can also be operated in "low" regen mode, which means the left pedal isn't left feeling all lonely.

We learned about how long it takes to charge the Bolt on regular power at CES, but we now know there are other options for buyers anxious about not being able to quickly top up. If owners are willing to stump for the optional DC fast-charger, they can expect to gain 90 miles (145 km) of range in just half an hour.

The Bolt should retail for around US$30,000, although Chevrolet points out that price includes a federal tax credit of $7,500. In other words, this is a US$38,000 car that gets significantly cheaper when government rebates kick in.

Stay tuned for all the action from Detroit, where Gizmag is on the ground covering all the action.
