Worse still, it actually increases the consumption of fossil fuel stocks. E-85 is an 85/15 mixture of ethanol/gasoline. A car running E-85 uses 40% more of this blend than straight oil-based gasoline. It takes energy - usually natural gas or coal - to convert corn or other sources to ethanol. The use of coal in E-85 production, in particular, eliminates the enviornmental advantages of running motor vehicle on alcohol-based fuel.

< See related stories >
November 30, 2005
Volvo has begun production of FlexiFuel cars powered by engines running on E85 (85 percent ethanol / 15 percent petrol). The 92kW 1.8F engine will available on S40 and V50 models, initially only on the Swedish market.
Ethanol can be made from biomass such as wheat, sugar cane, corn or cellulose. When running on E85 bio-ethanol, emissions of fossil carbon dioxide are as little as 20 percent that of a petrol-fuelled car.
However, it's not perfect, as shown by these figures:
Petrol/E85 engine specifications:
Power: 92 kW.
Torque: 165Nm at 4000rpm
'Four of Volvo's seven models are offered with an alternative driveline powered by a renewable fuel'
.
Acceleration 0-100 km/h: 10.9sec (S40), 11.0sec (V50).
Top speed: 200km/h.
Fuel consumption: 7.4 litres/100 km (S40), 7.5 litres/100 km (V50).
…BUT these figures relate to running on 100 percent petrol. Fuel consumption when running on E85 bio-ethanol is about 40 percent higher since ethanol contains less energy than petrol.Well, well. Would Exxon-Mobil try to pull one over on you under the guise of "greener, sustainable energy self-sufficiency"? Figure it out for yourself.
