The ultra-green machine has a 2.8-litre, twin-turbocharged engine based on the GM global V6 made in Australia. However, the engine in the Aero X has been developed by Swedish engineers to run on bio-ethanol.
Saab says the bio-ethanol engine does not increase greenhouse-gas levels because its CO2 emissions are balanced by the amount of CO2 that is removed from the atmosphere when crops for conversion to bio-ethanol are grown.
It has 298kW of power, 500Nm of torque with a seven-speed double-clutch manual gearbox in a lightweight carbon-fibre body.
Saab says it is theoretically capable of 0-100km/h in less than five seconds.
Several new concept cars are expected to debut at the show along with key new production models, including the all-new Toyota Aurion, the Ford BF II Falcon and Holden's new Captiva 4WD.
