Infiniti chose to debut its AMG- and M-fighting Infiniti Performance Line (IPL) at Pebble Beach in August with the introduction of a kitted out and specially tuned 348-horsepower G37 Coupe. The Japanese premium brand followed Act 1 up with Act 2 in Paris last month, now shining its spotlight on a conceptual IPL version of its G Convertible.

"The Infiniti Performance Line is designed to push the premium performance envelope for buyers seeking a higher level of exclusivity and driving exhilaration," commented Infiniti's US vice president Ben Poore. "IPL promises unique driving attributes from other Infiniti models, without adding stratospheric prices."

The gets most of the same upgrades as offered with the Coupe version, although like the standard-tune G Convertible power may be downgraded slightly. All the same, a factory-designed body kit will be part of the package as will some chassis tweaks to tighten and firm the already sporty ride to Z-like levels.

When the IPL G Convertible hits the road, it will be one of few factory-tuned topless sports models in its class. Lexus doesn't have a high-strung F version of its IS-C, whereas Mercedes-Benz and Cadillac don't even have convertible versions of their respective C-Class and CTS models. From a performance perspective BMW will reign supreme with its 420-horsepower M3 Convertible while the IPL G Convertible will edge out Audi's 333 horsepower S5 Cabriolet handily.

In the IPL G Coupe, the 3.7-litre V6 spins to a lofty 7,400 rpm after making a robust 276 pound-feet of torque at 5,200 rpm. It gains 18 horsepower and 6 pound-feet of torque over the standard G37, the result of a high-flow exhaust system and a recalibrated ECU; the usual first step an aftermarket tuner would take for a modest bump in performance.

Like those tuners, the transmissions are left untouched, with the standard close-ratio six-speed manual and optional paddle-shift actuated seven-speed automatic intact. A viscous-type limited slip differential moderates rear-wheel slippage while grippy 225/45 front and 245/40 rear Bridgestone Potenza RE50A tires lock the car to the tarmac.

Infiniti tuned the suspension in the IPL G Coupe too, increasing spring rates by 20 percent up front and 10 percent in the rear, while the brakes have been given a mild upgrade. We'll have to wait to see if the same specifications are applied to the production IPL G Convertible, as the one shown in Paris was only a prototype.

Unlike an aftermarket-tuned offering, all of the IPL G Convertible's upgrades will be completely covered by Infiniti's comprehensive warranty, including its many styling enhancements beginning with new front and rear fascias, revised side sills, a larger rear spoiler and 19-inch wheels. Inside, upgraded sport seats get meatier bolsters and manual thigh extenders, plus torso and thigh support adjustment, while extra metal trim adds to the exclusive look.

Don't expect pricing for this nicely modified G37 to be near the $82,300 being asked for the M3 Convertible, but rather it will likely slot in below the $68,300 needed for the Audi S5 Cabriolet.
