MotorTrend tests the 2012 W218 Mercedes CLS63 AMG with M157 twin turbo V8 Performance Package - 12.1@121
12.1@121 is the fastest time we have seen so far for a Performance Package M157 twin turbo V8. You might recall that Insideline tested the S63 AMG
with the performance package and hit 12.3@116 in the much heavier S class. The lighter (4256 pound) CLS63 puts up some very impressive numbers with 0-60 under 5 seconds and a low 12 second time. We have no doubt this means the lighter E63 AMG will hit 11's stock and about 124 mph in the 1/4 with the Performance Package.
