I liked the sound of Lotus' recent prototype ' trifuel' Exige, which uses Ethanol and Methanol based fuels as well as your standard unleaded fuel, within the same engine, so you can use whatever you want.
Huh... do you sacrifice performance or mileage because it' s compatible with all of those?
It was just an MSN article I was reading, but with alcohol based fuels apparently you get 0.2secs off the 0-60mph and an extra 10mph on the top speed, over standard unleaded petrol.
There are no figures for fuel consumption, but thats where the compromise is, burning quicker and hence doing fewer miles per gallon. But alcohol based fuel creates less CO2 overall from the exhaust AND can use atmospheric CO2 to create the fuel renewably.
The standard Exige S is quoted to do 31mpg (probably a lot less on a track!) and emit 216g/km of CO2 - putting it into the ' significantly tarry footprint/ feel guilty about killing the planet' catagory.
But every little helps right? Its still ' gas-powered' I guess, but I can' t imagine driving an electric/hydrogen/solar powered/cow-fart powered performance car anytime soon.
Did anyone see the first episode of the new series of Top Gear? Its never scientific, but Jeremy was saying the process of making batteries for the hybrid Toyota Prius is so complicated, they cause more damage to the environment overall than a Land Rover. Then they raced a Prius against a BMW M3 and the M3 managed a better mileage going round the track, heh.
