Lotus reveals its Trifuel Exige 270E concept car

Lotus has revealed its Trifuel Exige 270E concept car, demonstrating the sportscar maker’s belief in the future of methanol as an automotive fuel. The 270E uses the supercharged Toyota engine from the conventional Exige and can run on three different fuels: petrol, ethanol and methanol, or any combination of the three. Sensors measure the proportions of each fuel in the mix and adjust the engine management accordingly, meaning the new Lotus only needs one tank. Unlike hydrogen, which must be stored at very high pressure, or at temperatures as low as minus 253deg C, methanol is a liquid at room temperature. It can also burn with greater thermal efficiency than diesel, explained James Turner, Lotus’s head of powertrain research, and Richard Pearson, a technical specialist on the engine project. It therefore offers a vastly more viable solution than running internal combustion engines on liquid or pressurised hydrogen, and it is also a more convenient energy source for a fuel-cell vehicle.Most attractively of all, given the current environmental pressures, methanol can be synthesised from a mixture of hydrogen and carbon dioxide – one of the gases that we are told is responsible for global warming. Given that hydrogen can be extracted from water, using nuclear or solar energy, it’s easy to imagine how the whole process of manufacturing and burning the methanol could be carbon neutral. The supercharged Elise also demonstrates the other benefit of methanol: it has a higher octane rating, allowing it to produce more power. With no other modifications the output of the supercharged Toyota engine goes from its standard 237bhp to 266bhp. Lotus has no plans to sell the 270E, instead it is being used to demonstrate the relative ease with which an internal combustion engine and its fuel systems, whose seals and pumps need to be resistant to the corrosive properties of alcohol-based fuels, can be modified to run on ethanol and methanol. The company reckons the cost would be around £40 per car and that every new car should have multi-fuel compatibility.

Re: Lotus goes for methanol power

Just to add a few facts to the discussion...

-until a couple of years ago all Indy cars ran on 100% methanol fuel. Today they run on ethanol primarily because the ethanol industry provides the fuel at no cost

-Los Angeles ran a fleet of M90 fueled Ford Escorts over several years in the 80s. Their average driving range was 230 miles with M90 and 300 miles with gasoline. Methanol burns more efficiently than gasoline which explains why a simple conversion based on btus is not correct.

-a recent Chinese study in a laboratory showed no measurable difference in fuel consumption using M10 instead of gasoline.

-while methanol can be made from "renewable" resources this doesn't make much economic sense. Almost all methanol used in the world today is manufactured from natural gas....not green but a whole lot better than gasoline. Someone also noted that methanol is poisonous which is true but I would like to meet the last person who drank gasoline and lived to tell the tale!

-methanol today sells at about $1.20 per gallon, ethanol about $2.60 per gallon and wholesale gasoline about $3.00 per gallon. Everyone could save money by using methanol in their fuel supply

The conclusion that I reach is that methanol is a valid fuel that should form part of the fuel supply but sadly politics and vested interests conspire for this not to happen

And I would expect, that if you're going to name an article, that it would support your point.

Wind power ticks more good boxes than almost any other option. It is clean, nearly silent, emits no CO2, pays its way, and is "home made" - no small matter as Europe's reliance on imported gas jumps from 54pc to 80pc over the next 15 years.

"Those who don't like wind power have a duty to offer an alternative. So far they haven't really come up with anything," said Dr Bernotat.

Few working on the front line of the global energy crisis would disagree.

As for subsidies - find me an electricity generation method which isn't subsidised, or wasn't set up with government help. In Germany (as you've brought it up), 30% of all trade and industry subsidies go to coal mining. BNFL, CEGB - public sector.

Solar - perhaps not in the UK, but globally the potential is there. More interconnections between national grids, and more energy storage on the grid are required. We already use pumped-storage hydro to meet fluctuating demand.

Nice logic JJ. I needed a laugh...
