The Infiniti IPL G Coupe further hones the G37S' performance edge, but is it enough to run with the likes of BMW's M division or Mercedes-Benz' AMG branch?

Twenty percent stiffer springs help the IPL G to stay flat in the turns, while retuned dampers keep the ride from getting too harsh.

Large 19-inch wheels fill the wheel wells at each corner. Inside you can see that uprated brakes have been fitted to help the G to slow quickly and consistently.

A zero-lift aerodynamic kit has been fitted to the IPL G Coupe to help with high-speed stability.

Under the hood, the 3.7-liter V-6 engine has been massaged to output 18 more horsepower and 6 more pound-feet of torque.

The seven-speed automatic gearbox remains an option, but drivers can also opt for a six-speed manual shifter.

A freer flowing exhaust system no doubt helps add just a bit of that extra power.

However, mostly the retuned exhaust gives the G Coupe back some of the audible character that was lost in the transition from the old G35 to the G37.

However, this louder exhaust, when combined with the increased road noise from the suspension and wheel upgrades, can make the IPL G's cabin a noisy place to be at highway speeds. This is a less than ideal road-trip car.

IPL badges further illustrate that you've chosen the first model in the Infiniti Performance Line.

We moaned and groaned about the Infiniti G37 Convertible's lack of trunk space, but the G Coupe doesn't seem to have much more room in its trunk for your junk.

However, as this sticker illustrates, you can fit a pair of golf bags back there.

The red leather seats feature heated surfaces and power adjustments. The driver's seat even has power adjustable back and hip bolsters to keep you from sliding about during high-G maneuvers.

With the exception of the seats, you'd be hard-pressed to tell the IPL G Coupe from a standard G37 Coupe -- which is a good thing, because the standard G's cabin is remarkably comfortable for the price.

The steering wheel feels a bit large for performance driving, but felt nice in my hands. A pair of the nicest feeling paddle shifters in the business can be found mounted on the IPL G's steering column on seven-speed models.

Voice command and audio controls can be found on one side of the steering wheel's face.

The other side of the wheel is home to the cruise controls -- which are of the nonadaptive type in this performance-oriented coupe.

Infiniti's electroluminescent instrumentation is crisp, attractive, and easy to read at a glance.

The infotainment system can be controlled via this physical knob, via voice command, or by simply touching the screen's surface. Choice is a good thing.

The IPL G Coupe uses Infiniti's hard-drive-based navigation system, which is rather easy to use. It's a bit dated-looking in the wake of Audi's and BMW's latest offerings, but we have no major complaints about its operation.

The user is given a reasonable amount of control over how the maps are displayed, as illustrated here.

Many of the navigation system's physical and touch-screen accessible options are locked out at speed, but voice command remains available.

The Bluetooth hands-free system also rolls audio streaming in when paired with a compatible smartphone. Dial by voice allows users to verbally call up their contacts by name.

Traffic data is rolled into the navigation system and is factored into the Infiniti's routing algorithms.

Likewise, users can view weather forecasts and maps. Critical weather warnings can even be automatically spoken by the audio system when they appear in the vicinity or on your chosen route.

Digital audio sources include USB, iPod connectivity, Bluetooth A2DP streaming, CD/MP3 playback, and a hard drive MusicBox that stores ripped audio.

A premium Bose audio system is standard on the IPL, supplying balanced audio and strong bass.
