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.

Saab's modular hybrid system features a maintenance-free, 300-volt battery bank designed to last the lifetime of the vehicle, a 38 kW rear-mounted electric motor, a 15 kW integrated starter generator and all-wheel-drive with electric power transmission to the rear wheels. The entire system has been packaged without sacrificing cabin accommodation or trunk space, as demonstrated by its unveiling in the Saab 9-3 Convertible.

The all-aluminium 2.0-litre BioPower engine is modified to run on pure E100 bioethanol fuel, giving zero fossil CO2 exhaust emissions, and operates in tandem with the electrical power system. This offers fuel-saving stop/start functionality, torque boosting electric power assistance on demand, an electric-only 'Zero Mode' for city driving and regenerative braking.

The BioPower Hybrid Concept prototype car, a 9-3 Convertible with automatic transmission, is expected to achieve zero to 100 km/h acceleration in just 6.9 seconds, a substantial improvement against 8.8 seconds for the equivalent petrol model. Even more impressive is 80 to 120 km/h acceleration on 'kick-down' in only 5.5 seconds.

The Saab BioPower Hybrid Concept is the first project to be announced under a joint investment programme between General Motors R&D (Research and Development) and the Swedish Government. This has seen the establishment of a research and development office in Trollhättan, Sweden, focusing on vehicle safety, engine emissions and advanced manufacturing in collaboration with Swedish universities, research laboratories and suppliers.

Saab is a 100 percent subsidiary of General Motors which is committed to reducing vehicle emission and improving fuel economy through the implementation of a three-tiered, advanced propulsion technology strategy. The ultimate goal is the introduction of hydrogen fuel cell powered vehicles that emit only water and remove the vehicle from the environmental debate.

In the near to mid-term, hybrid propulsion will bridge the gap between today's technology and tomorrow's hydrogen fuel cell powered vehicles. GM is also focused on introducing alternative fuels and new technologies to improve the efficiency of internal combustion engines and transmissions, further reducing vehicle emissions and increasing fuel economy.
