The new fascia as well as the enormous space for the three-pointed star are an easy give away. It seems the headlamps are slightly more upright and shorter than those found in the current SL.
Mercedes-Benz has covered the entire hood in plastic cladding, making it difficult to see if there any new creases. Perhaps the German company is planning some more aggressive lines to see the SL's styling look similar to the SLS'.
It's likely Mercedes-Benz will unveil the car towards the end of this year.
