Today I heard from one of our AMG sources that the new CL 65 AMG's 1000 Nm torque figure is actually electronically limited! Without limitation, the CL 65 AMG engine delivers impressive 1200 Nm torque. Ouch.

Two additional rumors: up til now, all engines seem to deliver substantially more than the claimed 612 HP, around 650 HP are in the word.
0-300 kph acceleration is rumored to be in the 22(!) seconds range. Ouch again. Just for comparison: the Lamborghini Murcielago has been tested slightly under 30 seconds. Ouch again.
