VW shows Cd value: 0.237 hybrid concept

VW unveils the Up! Lite concept car at the L.A auto show. It uses a 2 cylinder diesel and electric drive motors. It also has a very smooth tapered body style, rear view cameras instead of mirrors, automatic self adjusting grill opening and flattish 18" wheels for 70 mpg highway. "The image of the car body with its clean lines, as though sculpted from a block of aluminium, underscores just how fascinating a car tuned to aerodynamic perfection can look."
