Ha!!
That pic makes the Camaro look like a little midget!!
and people were worried about weight. 
I think it's a touch wider than the Avenger. maybe by a couple of inches...but no more.
For reference:
The Dodge Avenger is:
58.9 Inches high, and
72.8 inches wide.
with ~5 inch ground clearance.
Corvette is 72.6 inches wide...and the Camaro is wider than the 'vette. (As per Fbodfather.) so it stands to reason that the pic is skewed a bit.
