According to wiki the most powerful version of the charger produces 424 hp.
The Standard Enzo produces 651 hp.
Which means the Enzo is more powerful.
The Charger weighs almost 2 tons.
The Enzo, due to his carbon fibre body, weighs 700kg less.
The Enzo has better brakes, which means it can break later and harder before a corner or evasion. The Enzo’s active aerodynamics that produce a lot of downforce also help with cornering.
The Charger is heavier and less aerodynamic, which means he has to take corners slower and has to break earlier, meaning the Charger loses time that the Enzo would use to play out its superior acceleration (3.14 s from naught to 60, the Charger needs 6 seconds, hello weak engine and heavy body) to pull away from the Charger and disappear between the traffic.
So as I see it, in conditions that allow a race (not a congestion where you stand still, like grisaille puts forth), the Enzo would win easily.
When the Enzo wants to evade a car in front of him, he has to break later and less hard (if it has to break at all) than the Charger, which would have to break much earlier. Also the Enzo is less prone to spinning out of control while doing it, due to its superior suspension.
Enzo pulls away.
When they come to a corner, again the Enzo is quicker around it, for the aforementioned reason.
In a straight, the Enzo quickly pulls away from the Charger.
It really is no competition. It is like comparing a Golf GTI to a Porsche 911.
And if it is the FXX: The FXX has 800hp and is even lighter than the normal Enzo.
The Dodge Viper, which is both lighter and more powerful and faster than the Charger, was ca. 9 seconds slower than the standard enzo on the Top Gear test track (which has some hard corners) and and 18 seconds slower than the FXX.
