Thanks to Saab Global’s hybrid site, here’s a bit more detail as to what components are what when it comes to this new drivetrain concept from Saab. The details that correspond to the numbers are below.

The Saab 9-3 BioPower Hybrid Concept is just as easy to drive as its petrol or diesel powered siblings. Energy use and power distribution is fully automatic. The only visible differences from a conventional car are a few instruments and the Zero Mode switch. Despite its compact design, the Saab Biopower Hybrid is a full hybrid vehicle, which means it has the capacity to be driven entirely on the stored electricity.

1. Saab BioPower 2.0 Turbo – combustion engine optimised to run on pure bioethanol (E100), resulting in zero fossil fuel emission.

2. Integrated starter/generator (ISG) – built into the flywheel, between the engine and transmission. Contributes with an additional 15 kW (20 bhp) and up to 120 Nm of torque

3. Rear Drive Unit (RDU) – transmission differential with an integrated 38 kW (52 bhp) electric motor/alternator. Deliver up to 665 Nm of torque briefly at lower speeds to boost take-off performance.

4. Battery Management System (BMS) – Electronic Control Unit with software for battery supervision.

5. 42 V battery – powers the front electric motor (ISG).

6. 300 V battery – powers the Rear Drive Unit. Compact, high-capacity lithium-ion battery.

7. Electronic Control Unit – for the Rear Drive Unit (RDU).

8. Zero Mode button – switch between Hybrid and Zero Mode. Driving range in fully electric Zero Mode is 10–20 km depending on driving conditions.

9. Electronic Control Unit – for the Integrated Starter Generator (ISG).

Saab BioPower Hybrid Concept: World’s First Fossil-free Hybrid Vehicle

· Innovative hybrid concept based on pure bioethanol

· Zero fossil CO2 emissions in all modes

· 260 bhp Saab BioPower engine running on E100 fuel

· Increased performance with threefold torque boost from electric motors

· Fuel saving ‘Zero Mode’ for city driving on electric power only

· Energy saving features including regenerative braking

· Space efficient modular design uses existing vehicle architecture

· All-wheel-drive for improved traction

The innovative Saab BioPower Hybrid Concept, making its world premiere at the Stockholm Motor Show (March 30 – April 9, 2006), delivers zero fossil CO2 emissions, enhanced performance and a range of energy-saving features by combining the use of pure bioethanol fuel and electric power generation for the first time. As the world’s first fossil-free hybrid vehicle, the Saab 9-3 Convertible show car also becomes the world’s first hybrid soft-top.

Packing formidable pulling power from its 260 bhp (191 kW) 2.0-liter turbo BioPower engine and 53 kW electric motors, the BioPower Hybrid Concept in the Saab 9-3 can briefly generate torque values three times greater than its gasoline-only equivalent. It is a sporty combination that makes for improved performance, as you would expect from Saab, as well as greater fuel economy and an extended driving range.
