Saab has announced that it will preview its latest bioethanol-powered engine at the Geneva Motor show next month.
The E100 (100% ethanol) compatible turbocharged 2.0-litre engine will be capable of developing 300bhp.
Saab has fitted the engine in a 9-5 estate giving it a claimed 0-60mph acceleration in 6.6 seconds.
The Biopower 100 concept has also received a few styling mods to emphasise its speed and sportiness.
GM Powertrain CEO Kjell ac Bergstrom said: "Bioethanol is a potent, high-quality fuel which opens up exciting possibilities in helping to meet the environmental challenges that face us. 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 'right-sizing' process, while also minimizing fossil fuel emissions".
