For 2017, Porsche has redesigned the Panamera. Most will agree that the outline of this 2nd-generation, aluminum-body sedan is an improvement on the original design. It is longer, wider, & taller, but has a lower roofline, giving it more familiar Porsche styling. It will be available with a twin-turbo 2.9-liter V6 that outputs 440 HP or a 550 horsepower twin-turbo V8 that goes 0–60 in 3.6, with a top speed of 190 MPH.
