Here are the latest photos showing the Mercedes AMG SLS Black Series during cold weather testing in the artic circle.

The car is a direct replacement for the SL65 AMG Black Series from 2008 and we expect it to be as insanely dangerous in this form.

It will be badged as the SLS AMG Black Series and is expected to output around 690 ponies, This is where information is vague as engineering the current 6.2-liter V-8 up is one possibility but unlikely, The other is introducing the new 5.5-liter twin-turbo V-8. From the large air intakes on the front of this prototype it could be feeding the Twin intercoolers required for the forced induction.

Also the detailing is showing a wider track along with the usual Black Series aggressive arches along with clever use of composites to reduce weight, we also expect numerous chassis and brake modifications to mate to the increase in power and torque.

This car is still in Prototype mule form from the current SLS and is likely to have another 2-3 months to go before the production prototype will be spotted probably at the Nurburgring in early may.
