The awesome new Mercedes CLS63 AMG will go on sale from March with a fully loaded model to cost nearly 125,000 euros. But it’s worth it becasue as you see in these new videos, it looks great, goes like hell and sounds so dirty! AMG cars are very complete cars. They have fabulous styling, magnificent luxury, huge speed and so on. But the most incredible AMG feature for us, among a sea of incredibleness, is the noise they make. Just listen to the CLS’ brand-new 5.5 liter biturbo V8 in the promo video above, and then hit the jump to see an extensive driving footage of this superb vehicle.
