Saab’s new BioPower hybrid concept makes its world premier today at the Stockholm Motor Show.

The new concept is the first in the world to produce no fossil C02 emissions by using an engine which runs on pure ethanol and electricity. It is also the world’s first hybrid soft-top.

The concept is powered by an all-wheel drive 260bhp 2.0-litre turbo BioPower engine and 53kW electric motors. It uses fuel-saving stop/start functionality, electric power assistance on demand and 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 0-62mph in 6.9 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.
