HP numbers to boost the "ego" have become pointless and irrelevant. Jeep Trackhawk will pull the same 0-60 with the 707HP and its all wheel drive as a Z06.
If that's not quite enough, for a bit more you can have a Jeep Trackhawk from Hennessy with 1000 HP and 2.8 0-60 and 10.6 quarter mile... Need I say more?
