The Lotus Exige 270E Tri-Fuel is the successor to the 2006 Exige 265E, which could operate on either gasoline or E85 Ethanol. (The "265" stands for the amount of horsepower produced and "E" stands for E85.)
The next generation of the Exige raises the bar by being gasoline and E85 compatible as well as Methanol, giving it the Tri-Fuel designation. The methanol produces 270hp and 185ft/lbs of torque from a supercharged 1.8L engine, which will get you from 0 to 60mph in 3.9 seconds. Green is good.
Lotus is also working toward a Carbon-Neutral Synthetic Methanol. The process involves taking Carbon-Dioxide already in the atmosphere and causing a reaction with electrically produced Hydrogen, the result being Methanol. As an added bonus, liquid methanol can be transported and distributed in a very similar manner to gasoline, negating the need for a complete redesign at fueling stations.
