Spotted testing again is the Mercedes-Benz C63 AMG sedan.
Oh, we forgot about one teeny, tiny element. The new version we've spotted testing is the C63 AMG Black Series sedan.
How do we know? Well, it doesn't take a rocket scientist to spot the major changes.
1) Suspension - Clearly this vehicle is much lower, particularly in the rear.
2) Fender flares - LOOK at those front fenders! Mercedes must have widened the Black's front track significantly. In addition, do you see the added venting a la C63 Black Coupe?
3) Front valence - If that's not a Black Series-inspired valence, I don't know what is. It looks akin to the SL Black Series' fascia.
Though Mercedes-Benz has so far remained mum on the topic, I'd be willing to wager that after the success of the C63 AMG Black coupe, where Mercedes actually increased production, it can certainly make the business case for a sedan that will likely sell in droves as well.
