Why so slim?

[loose]

I know I'm new to the r/c scene but can anyone tell me why lots of new cars seem to be infactuated with getting slimmer?

Are there any huge improvements to handling by keeping the weight as narrow as possible? I only ask cos whilst its great having new cars like the Aero (which undoubtedly looks like its the real deal) I cant help thinking the thin bodies look a bit pants! I saw a Boss Cat at one of the vintage meetings and that looked the dogs! Loved it!

I suppose its the old Kate Moss or Kate Winslet debate. I like a few curves personally!
