I have been waiting and waiting, as this may be my next car (in 400 hp form) but two reviews have trickled out. Positive! it looks like both hybrid and 2.0 were tested. Take a look.

My favorite compliment:
"But here’s the thing: As much as I craved to sample the powerhouse V6, the MKZ’s standard engine — a carryover but retuned 2.0L turbo — behaved so well and spooled out so much fun that few will go pining for more."
A worrisome comment:
"And despite the MKZ’s exotic looking interior and exterior, space is an issue. Head room for front passengers is limited, and leg room for rear passengers is non-existent when the front seats are set for a six-foot tall person."
