Yeah I read that too. Wonder where I read that it had only the software--it might even have been on this board, but I can't remember.
691bhp...yikes!
I would love to see the torque curve for this monster. At its lowest torque output, it should be able to pull away from anything and everything. I tested a 2004 Viper--it could start off on a slight uphill in 6th gear without lugging--at idle! I can't imagine what this car could do (probably pull a house)!
