Saab will reveal the latest incarnation of its BioPower technology at the Geneva Motor Show.

The BioPower 100 concept is an evolution of the 9-5 estate car and produces 300bhp from its 2.0-litre high octane bioethanol engine.

“Bioethanol is a potent, high quality fuel which opens up exciting possibilities in helping to meet the environmental challenges that face us,” says Kjell ac Bergström, president and CEO at GM Powertrain – Sweden, who has led the Saab BioPower 100 engine development team.

“As the need to reduce energy consumption increases, we are exploring ways to run smaller engines that give relatively high power, with and without hybrid technology.

"This concept car shows that bioethanol can play a key role in this ‘rightsizing’ process, while also minimising fossil fuel emissions,” he added.
