By combining turbochargers and direct fuel injection and augmenting them with a novel way to use a small amount of ethanol, Cohn and his colleagues have created a design that they believe could triple the power of a test engine, an advance that could allow automakers to convert small engines designed for economy cars into muscular engines with more than enough power for SUVs or sports cars.

Very good story. Now I actually know what knock is. I'd be excited by that engine.

Most interesting news. I really hope that this type of technology is implemented into everyday engines by the 2011 forecast that they estimated.

yes, sarcasm. i agree it seems like they think they captured cold-fussion or something, but i don't think their findings are to be thrown out. the vw discovery is pretty clever, i must say. perhaps both methods could be used.

Ethanols is hype. Bio diesel is 4 times better. In the amount of energy gained.

Direct injection+turbo was pioneered by Audi with its Le Mans racing R8. Now available on most Audis.

Make the engine, then bolt-on a hybrid system.

Old news VW did this last year (or two years?). What about the gas motor that ran on high compression with high torque and improved mpg.Does anyone remember the name? HH something?That impresses me more!
