In all fairness, the 69 GTX in that magazine test was rolling on ritz crackers. New challenger has some serious rubber under her.

However, a huge difference is the new Chally's braking performance is repeatable all day.



The GTX was the hot rod of it's day and the Challenger is the same. Tire technology does play a significant role.

Here's more pedestrian examples from Motor Trend:
2006 Buick Lucerne: 3795 lbs, 235/55-17 tires, 60-0 in 136 ft.
2006 Mercury Montego AWD: 3954 lbs, 225/55-18 tires, 60-0 in 127 ft.

These cars are similar in size and weight to the GTX. The tires are skinnier than what the GTX had but are obviously made from new compounds. Both of the cars had disc brakes between 11.0 and 12.0 inches in diameter front and rear.

An interesting comparison are these two cars:
2006 Chrysler 300 Touring: 3776 lbs, 215/65-17 tires, 12.6" discs front and rear, 60-0 in 134 ft
2005 Chrysler 300 SRT8: 4190 lbs, 245/45-20 and 255/45-20 tires, 14.2" front discs, 13.8" rear discs, 60-0 in 113 ft


*edit* I did a little fiddling with the numbers. The difference between the 300 Touring and 300 SRT8 is 11369 lb/ft and the brakes are able to stop the greater mass in 21 fewer feet.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
