Ookay, excluding the 100k Tesla roadster......which is faster than a stock SRT-6. I can only think of two hybrids that are faster 1. GS450h and 2. LS600h, which both list for quite a bit more than the crossfire did new.

The Rx400h is quick but not fast enough and same for Honda Accord Hybrid, though it is pretty much as fast. But nothing that I would quanify as quite abit faster.
