The 348-horsepower G hardtop wears a factory-designed bodykit and came with engine and chassis tweaks to make things slightly firmer and faster. It goes on sale in December.
This week, its droptop brother will arrive at the Paris Motor Show. Infiniti hasn't announced power output, but we expect the IPL G Convertible Concept will probably be a shade less muscular than the coupe, as is the case with the non-IPL models. The automaker hasn't given away any hint of pricing, either, but VP Ben Poore did say "IPL promises unique driving attributes from other Infiniti models, without adding stratospheric prices," if that's any consolation. Stay tuned for complete details later in the week.

I got a G37 convertible as a loaner last week. Nice car. My one overwhelming gripe with the car was the placement of the rubber antenna. Right in the center of the trunk? Makes it hard to use the rear view mirror. Otherwise, I thought it was nice.
