Today Mercedes Benz has announced the addition of two new top-of-the-range AMG models to its SL product range - the SL63 and the SL65 AMG.  To maintain some momentum ahead of the official launch, Mercedes has published only a three-quarters rear view teaser image of the V12 bi-turbo SL65 flagship model, leaving the front end restyling open to speculation. In earlier spy photos we've seen a completely restyled front end.

Aside from the aggressive new rear diffuser with the quintessential AMG quad exhaust pipes, a small rear spoiler and what appears to be "997 Turbo"-inspired wheels, the rear of the facelifted SL AMG model looks hardly different from the pre-facelift model.

What we know so far is that the SL 65 will be powered by a 6.0-litre bi-turbo V12 powerplant putting out some 612 hp and torque in excess of 1,000 Nm. The SL 63, replacing the SL 55, will get a 525 hp V8 with 630 Nm of torque. Coupled with AMG's seven-speed "SPEEDSHIFT MCT" gearbox, these latest AMG beasts should offer true 'Fahrspaß.'
