2014 Mercedes Benz SLS AMG Black Series Spied at Nurburgring [Video]
Right now, there are three possible options for the engine of the SLS Black. First off, the 6.2-liter naturally aspirated V8 could be tuned once again, but the 5.5-liter V8 and 6-liter V12 that are found in the new R231 SL63 AMG and SL65 AMG are both possibilities.
To us, the car in the video sounds a bit like the V12, which would be good choice for turning the SLS into its ultimate form ever.
Whatever the case, it’s clear that the gullwing has received the usual Black Series kit - bigger intakes, chassis upgrades, a wider body and track, plus upgraded brakes and suspension for track use.
