In significantly lamer news, the same execs also said the street-legal version of the SLS AMG GT3 will not make it to this side of the pond. Apparently, the enormous cost of certifying the car for the U.S. isn't worth it, given its extremely low volume.
As for the SLS AMG E-Cell, ze Germans still haven't decided whether that's coming here yet. The reason, again, is the cost of certifying versus sales volume. The car is slated to go on sale in late 2012 in Europe, and be a good bit heavier and more expensive than the gas burner.
