At the Frankfurt Motor Show, Opel intend to show what they are capable of once they are freed from their GM shackles. The electrically powered Ampera should give Opel a jolt in the right direction when it arrives in 2011. The 150bhp motor incorporates a generator which takes its range up to 500 kilometres (310 miles). The wheels are driven on battery power alone for the first 60 kilometres. At this point, a small combustion unit kicks in to recharge the batteries as the journey continues. The Ampera does not, however, count as an Opel innovation, as the drive technology stems from the Chevrolet Volt sister model.
