The new plug-in hybrid comes with an estimated range of 400 miles, 50 of which can be travelled on electric power alone.
For the second-generation Volt, Chevrolet has lowered the weight of the battery pack by almost 10kg, while the two-motor drive unit operates up to 12 per cent more efficiently than the outgoing car's.
The electric motors are coupled to a 1.5-litre petrol engine that develops 74bhp. When combined with the electric motors, the Volt's total output is raised to 118bhp, enough to cover the 0-60mph sprint in 8.4sec and give the Volt a top speed of 98mph. The new Volt should be capable of returning a combined 102mpg.
Charging time from a standard 13-amp socket is placed at 13 hours, while a fast charger drops that to four and a half hours.
The second-generation Volt is one of five new Chevrolet models coming in 2015.
