Additionally, the SLC is supposed to get a 487 horsepower V8 and a 544 horsepower Black Series variant. What motor is this based on? They don't say. Furthermore, Automobile states the model will actually be called an SLR which also does not make too much sense.
Frankly, it seems Automobile is pulling a lot of this stuff out of their rear end with no support from any official sources whatsoever. They even blatantly state these are rumors so it would seem they are just making this stuff up for hits in typical Automobile fashion.
BenzBoost would love for the SLC or SLR to come to market but until there is something official to back this up treat this all as a rumor and speculation.
