fatter engine, fatter transaxle, fatter rear sub frame, and probably fatter rear suspension. fatter wheels/ tires, etc... (i wonder if its an evora rear suspension, vs, and exige?) probably a bigger fuel tank, bla bla bla.. but yea... 600 - i can see 300 easy, but 600 seems rather excessive. also you are comparing the cup car (which is about 100lbs lighter than a regular exige right?) so its probably more like 500 lbs more apples to apples.
....but then again. according to danny "our new cars weigh more because of the thought that goes into them" they must have put some extra thought into the v6 exige.?
"I really started paying attention to cars was when they came out with the Nissan Z, the first body. Then I seen the Cherokees, the old square ones, and I was like, “Wow, that’s cool.” Then I seen the Isuzu jeeps and I seen the Wranglers."
