I’m really pleased to see that the G25 is a proper G — a sports car thinly disguised as a luxury sedan. But the G’s firmer, louder ride may not be to everyone’s tastes.

Ihe IPL G Coupe feels much like Goldilocks’ choice of porridge-not too hot, not too cold. Compared to the regular Infiniti G37 S, the IPL-tuned coupe feels a little less rough. Power gains feel more impressive than they likely are.

The IPL G Coupe feels like what you’d expect: a slightly hotter and very well-rounded Infiniti G37. The ride is a little firmer, but not harsh. Turn-in is precise but not darty.

If you’re shopping $40,000 sport sedans, the Infiniti G37 is required driving: It is smartly appointed, well-equipped, reliable and as much of a hoot to drive as the BMW 3 Series.

The second-generation Infiniti G satisfies both the left and right brain: It’s fun to drive and nicely appointed, yet it’s reliable and less expensive than many competitors.

The G25 is just as much sedan—just with a little less engine. You don’t give up anything else, however: it’s got the same conservatively aggressive good looks, the same austere but functional (if somewhat small) interior, and the same fantastic handling and suspension tuning.

The 2013 Infiniti IPL G convertible doesn’t raise the performance bar enough compared with the regular G37 droptop, and neither does it improve on that car’s shortcomings.

The Infiniti G sedan excels at driving dynamics. The interior is friendly and feature-laden without being too busy. The G is priced lower than most comparably equipped European competitors. We think it’s a good choice for performance-oriented drivers.

The priced right G25 offers all the power and features most any buyer could ask for from an entry-luxury sedan. Like a yoga master focused on strengthening the core, the G25 eschews the brute force of the G37 to deliver a very pleasing package.

Sport-focused, intelligently designed and attractively priced, the 2011 Infiniti G Convertible is an excellent choice for a luxury sport convertible.

With its V-6 engine, all-wheel drive, and sinewy looks, the 2011 Infiniti G37x coupe will make you the envy of the carpool lane, until the other parents see the effort it takes to get younger kids in and out of the backseat.

The Infiniti IPL G Coupe brings a fresh attitude to the luxury performance coupe segment. It’s brash, capable, and unapologetically rough around the edges. We don’t really see the point, but we had fun driving it anyway.
