In an article in the July 2012 issue of Car & Driver, Daniel Pund says of the 6.2-liter, naturally aspirated engine in the outgoing SL63:
Indeed, so good was the 6.2-liter that AMG engineers get wistful just talking about it, even in front of the meddling, judgmental press. Goodness, was it a lusty thing with perfectly linear power delivery, immediate throttle response, and an exhaust snarl that would cause wolverines in neighboring states to believe they’d heard the voice of their God.
Pretty much sounds perfect to me.
This is your brain on Hogs.
