Ferrari announced two goals for upcoming vehicles: to increase power-to-weight ratios and reduce emissions. To go along with some fairly ugly green stickers, their ethanol-fueled F430 prototype boasts 10bhp extra โ€” bringing the total to 493bhp โ€” and 5 percent lower emissions. It could be on sale by 2010, forming part of the company's pledge to shrink overall emissions 40 percent by 2012. Apparently, 5 percent at a time.
