Interesting comparison here of the Porsche Panamera 4 against the Porsche Panamera 4S. Enjoy!
After driving the V6 I was about ready to ascribe the lack of visceral thrills to the car as a whole—but then I drove the V8-powered Panamera 4S. The subjective difference is night and day, even if the objective difference from rest to sixty is only about a second (4.8 vs. 5.8, according to Porsche). It only winds a couple hundred rpm higher, and does no better in power per liter, but the V8 sounds and feels far more energetic than the V6. And this is before tapping the button to open up the $2,950 “sport exhaust,” which releases a bunch more burble. Even hobbled with all-wheel-drive the larger engine rotates the rear end at will, shoves the seat into your back, and encourages bad behavior in ways the V6 doesn’t begin to.
