Saab will unveil its latest BioPower technology – the first production-based engine to be optimised for pure bioethanol (E100) fuel – at the Geneva motor show next month.

The automaker said the new model demonstrates the great performance potential of bioethanol. The combination of turbocharging with high-octane E100 fuel boosts output of the two-litre engine to 300 hp.
Modifications to the engine management system and internal components allow the use of greater boost pressure with a raised compression ratio.
“This exceptionally high specific power output of 150 bhp per litre demonstrates scope for future ‘rightsizing’ – using small high output engines that also deliver energy savings,” Saab said.
Peak power is complemented by a substantial 400 Nm of torque, giving the engine similar power to a naturally-aspirated four-litre unit. The car accelerates from 0 – 62 mph (100km/h) in 6.6 seconds and accelerates from 50 to 70 mph in fifth gear in 8.2 seconds.

Saab already markets Europe’s best selling flex-fuel vehicle, the 9-5 BioPower, and claims the BioPower 100 Concept will extend its leadership in the development of bioethanol technology.
“Bioethanol is a potent, high quality fuel which opens up exciting possibilities in helping to meet the environmental challenges that face us,” said Kjell ac Bergström, president and CEO at GM Powertrain – Sweden, who led the 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.”
