As mentioned on this Board: 6.2L V8, 503HP and 465TQ. - "Having said that, we will employ turbocharging, primarily at the top-end of the performance end of the spectrum." - Two turbocharged iterations of the V8 are on their way: * A "relatively modest boost" to 563HP and 664TQ * A "mighty mauler provisionally rated at" 697HP and 886TQ - "The only evolution for the normally aspirated unit is an increase in displacement to 6.8L, which is a legendary number for AMG, dating back to the company's successful sedan-racing origins."
