GM’s Saab will introduce its latest BioPower concept car at the Geneva Motor Show next month, featuring its first production-based engine to be optimized for pure bioethanol (E100) fuel.
To be shown as an evolution of the Saab 9-5 SportCombi, the BioPower 100 Concept demonstrates the performance potential of bioethanol. In combining Saab turbocharging expertise with the use of high octane E100 fuel, the optimized 2.0-liter engine from the 9-5 range develops 300 hp (224 kW) maximum power.
This is enabled through modifications to the engine management system and internal components, allowing the use of greater boost pressure with an increased compression ratio. The high specific power output of 150 hp per liter demonstrates scope for future downsizing, using smaller, high output engines that also deliver energy savings.
Peak power is complemented by a substantial 295 lb-ft (400 Nm) of torque, giving this optimized engine the power characteristics of a naturally-aspirated engine of 4.0-liters displacement. The Saab 9-5 BioPower 100 Concept achieving zero to 62 mph acceleration in just 6.6 seconds and 50 – 75 mph (fifth gear) in 8.2 seconds.
The Saab BioPower 100 Concept being shown at Geneva features exterior and interior styling elements supervised by GME Advanced Design Director Anthony Lo, who oversaw Saab’s award-winning Aero X Concept, which was also premiered at Geneva last year.Saab’s 9-5 BioPower is Europe’s best-selling flex-fuel vehicle.
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 ‘rightsizing’ process, while also minimizing fossil fuel emissions.—Kjell ac Bergström, president and CEO at GM Powertrain - Sweden
