drag coefficient

[Wass]

I think that one of the things which I would like to see an improvement on the current CT 200 is the drag coefficient.. Considering that , like the prius , the CT200 was designed to be a high efficiency hybrid, and nothing else, its drag coefficient is almost as bad as a conventional engined body shell. The hybrid engine will burn less fuel than a conventional engine and therefore needs less engine cooling ( which is a major contributor to drag), The CT is also fitted with wide wheels which is another contributor to drag.   Narrow tyres, improved under floor aerodynamics, more aerodynamic wing mirrors coupled with  a bodyshell which isnt so tied to the Auris way of thinking might go a long way.  The new mercedes A class has a market leading drag coefficient and yet it still looks  the business. Lexus needs to up its game quite a bit if it chooses to promote its green credentials.
