Conflicting reports of output for the 4.0 twin turbo engine. The good news is likely to be that it has serious low-end torque whether in 450 or 520 trim. If it does have only 450 bhp and will likely be about $15-20k more than the NWB A8 with the usual options, the A8 will be my choice with the sport option, among others like dual pane glass, etc. A totally different car from the Pan 4S even if it does have 520 bhp--and one that I would favor over the Porsche.
