The SAAB Biopower Hybrid Concept car was unveiled this week at the Stockholm Motor Show. According to the press release:
The engine runs on pure E100 bioethanol fuel. In other words, its fuel is made from sugarcane, corn, and other kinds of biomass, which means it has zero carbon-dioxide emissions. When in the city, you can switch to all electric driving, allowing the 'gas engine' to shut off completely. The 'Zero Mode' kicks in below 31 mph and will last as long as the battery doesn't need to be recharged (6-12 miles).
With 260 hp (191 kW) 2.0-liter turbo BioPower engine and 53 kW electric motors, it is expected to go from 0 to 60 mph in 6.9 seconds. Its also capable of going from 50-75 mph acceleration on 'kick-down' in only 5.5 seconds.
The electric engine sports a 42-cell, 300-volt lithium-ion battery bank, mounted under the floor of the trunk. The 42-Volt ISG powers the hybrid stop/start functionality. It serves a multi-functional role as a starter motor, alternator and 15 kW engine power booster, while also helping to iron out residual crankshaft vibrations. The water pump, air conditioning and power steering systems are electrically powered leading to fuel savings.
"Hybrids are certainly interesting for Saab in the future and this project allows us to evaluate and explore the potential of hybrid technology in combination with BioPower," says Jan Åke Jonsson, Saab Automobile's Managing Director. "Although the exact hybrid application shown in this concept does not currently figure in our production plans, the project has been extremely valuable in helping us further our expertise. It shows how we could develop the sporty performance associated with Saab while using only renewable resources and saving energy overall."
