How does the Saab 9-5 BioPower increase power and performance when fuelled by E85?
The octane rating of E85 is higher than petrol, so when the BioPower car is fuelled by bioethanol E85, its advanced trionic engine management system operates the turbo engine at a higher combustion pressure, producing more power without risk of ‘knocking’ (premature detonation of the fuel/air mixture).
