The main problem here is a good one for Infiniti: In regular form, the refined G37 coupe is already incredibly capable and exciting, which sets the bar pretty high for the IPL. Why pay a hefty price premium for the IPL? Its ride is too firm, road noise is off the charts and you get only 18 more horsepower — which it didn't really need in the first place.

Compared with the competition, the IPL may look like a deal, but to go up against the Ms and Fs of the world, it needs to offer more.
