The 2010 Toyoto Prius is claiming a cd factor of 0.25. With only the Merc E class coupe and quite unbelievably the Audi A2 anywhere near it this is where all car design should be going. We must banish all those SUVs and 4X4 to the scrapheap of profligacy where they deserve to be sent.
Okay, I'm intrigued. What's the cd factor?
