TeamSpeed has released the first spy shots of the prototype for the new, more compact Maserati, spied testing in Germany. The car is code-named "M157" (or perhaps, Ghibli) and will aim to compete with models like the Porsche Panamera and Mercedes E-Class.

According to Maserati, the engine will be a turbocharged version of Chrysler’s 3.5-litre Pentastar V6 with an output of about 375 to 400 horsepower. Maserati expects to release official images of the M157 in late 2013.
