It is indeed quite a bit bigger than "our" Challengers.
6 inches longer in the wheelbase.
6.5 inches longer in the body.
2.5 inches wider.
6 inches taller.
Probably be about the same weight or up to 200lbs heavier.
This is a very big car.
A V6 version should be available for around $23,000 in todays money and the Hemi version for around $7,000 more.
If they had any sense they should also produce a smaller lighter, cheaper, Barracuda version.
