    LA 2011: Infiniti's IPL Does The G Convertible

    Infiniti is expanding their IPL lineup with the new IPL G Convertible.

    The IPL G Convertible is based on Infiniti's G37 Convertible with a number of subtle design and performance tweaks.

    The IPL G Convertible gets minimal changes on the exterior with unique front fascia with integrated fog lights and black finishers, sculpted side sills, chrome-tipped exhaust outlets, and unique 19-inch wheels finished in graphite. Only two paint colors are available: Moonlight White and Malbec Black.


    Inside, the only change is the choice of the color: Stone and IPL-exclusive Monaco Red.

    Under the skin, Infiniti engineers have improved the suspension to provide more confident handling. Also, Infiniti has added larger brakes to help bring it to a stop.

    The engine is Infiniti's stalwart 3.7L V6 with new software and exhaust system that brings the IPL G Convertible's horsepower to 343 and torque to 273. A seven-speed automatic is the only transmission option.

    2013 IPL G Convertible Joins Infiniti Performance Line Portfolio with Dramatic Styling, Tuned 3.7-liter V6


    The 2013 IPL G Convertible Infiniti, which is set to go on sale in spring 2012, becomes the second member of the Infiniti Performance Line of premium performance vehicles. First introduced with the dramatic IPL G Coupe, IPL’s product design philosophy focuses on “total vehicle performance,” including unique driving attributes and exclusive exterior and interior features at a highly attractive price point. The new IPL G Convertible features special aerodynamic styling pieces, the dynamic performance of an IPL-tuned V6, exhaust and suspension, 19-inch IPL aluminum-alloy wheels, and unique leather-appointed interior – along with the G Convertible’s three-piece retractable hardtop.

    “The Infiniti Performance Line, as demonstrated by our first offering, the IPL G Coupe, challenges the concept of ultra-high cost sports series. IPL pushes the premium performance envelope for buyers seeking a higher level of exclusivity and driving exhilaration, but does so with an Infiniti twist,” said Infiniti Americas Vice President Ben Poore. “Like every Infiniti, the new IPL G Convertible takes a different path from its established competitors, with its retractable hardtop that is designed to look as good with the top up as down. It’s a terrific addition to the Infiniti Performance Line, taking the dramatic Infiniti G Convertible to an even higher level.”

    Based on the premium foundation of the Infiniti G37 Convertible, the IPL G Convertible features an advanced VQ37VHR 3.7-liter V6. The engine management system has been recalibrated through air-fuel mixture and ignition timing optimization, raising the maximum horsepower output point to 7,400 rpm. To obtain a natural acceleration feel, the torque curve from low revs to the maximum torque point (5,200 rpm) was tuned for linearity. The IPL-tuned high-flow exhaust is a full dual exhaust design with independent left and right large diameter pipes. The muffler’s inner structure and materials have been maximized to reduce pressure and provide an appropriate performance exhaust note. The result is a 30% reduction in exhaust pressure versus a base G Convertible’s Y-pipe exhaust system design.

    As a result of both the exhaust system and engine management changes, the IPL G Convertible generates 343 horsepower – an increase of 18 horsepower over the non-IPL models – and 273lb-ft of torque (+6 lb-ft).

    The engine is matched to an electronically controlled 7-speed automatic transmission with Downshift Rev Matching and quick-shift Drive Sport (DS) mode with magnesium paddle shifters and Adaptive Shift Control (ASC).

    The IPL G Convertible’s enhanced dynamic vehicle performance focuses on providing confident handling, flat ride and smooth ride comfort. The IPL suspension tuning and damping management philosophy is designed to optimize each aspect of the suspension, effectively connecting the driver to the road surface while minimizing uncomfortable vibrations. Front spring rates have been increase 14% over the G Convertible Sport model and rear spring rates increased 4%. Front stabilizer spring rates have been increased 6% over the G Convertible Sport model and rear stabilizer spring rates increased 125%. Shock tuning has also been adjusted and incorporates an all-new HF-type shock.

    The IPL G Convertible also offers a sport-tuned steering gear and large 4-wheel sport brakes (14-inch front, 13.8-inch rear) with aluminum-alloy opposed calipers (4-piston front/2-piston rear).

    The IPL G Convertible’s unique exterior includes a dramatic front bumper/fascia design with integrated fog lights and black finishers, sculpted side sills and round chrome exhaust tips. Each part is shaped to complement the G Convertible’s elegantly seductive styling. Combined with the exclusive 19-inch IPL split 7-spoke graphite-finish wheels and low-profile W-rated Bridgestone Potenza RE050A performance tires, the IPL G Convertible embraces a road-ready attitude. The IPL G Convertible is offered in just two exterior colors: Moonlight White and Malbec Black.

    The IPL G Convertible interior harmonizes with the exterior styling, offering two color treatments – Stone and IPL-exclusive Monaco Red. All IPL G Convertible interiors include red-stitched leather-appointed Climate-controlled front sport seats with embroidered IPL logos, manual thigh extension and driver’s power torso and thigh support adjustment, red-stitched steering wheel, Silk Obi aluminum trim, IPL embroidered front floor mats, and aluminum trimmed pedals and footrest.

    Other standard IPL G Convertible interior features includes a 13-speaker Bose® Open Air Sound System, optimized for both top positions, with AudioPilot® 2.0 noise compensation technology and Personal® front seat headrest speakers, an Adaptive Dual Zone Climate Control that automatically adjusts fan speed and air volume based on top position, and Advanced Climate Control System (ACCS) with Plasmacluster® air purifier, Infiniti Navigation System with voice recognition and available XM NavTraffic® Real-Time Traffic Information, NavWeather™ with Real-Time Weather and 3-day forecast (XM® subscription required, sold separately), Streaming Audio via Bluetooth® and Zagat Survey® Restaurant Guide and touch screen, and Bluetooth® Hands-free Phone System.

    Technological and convenience features include standard Infiniti Intelligent Key with Push Button Ignition, Remote Keyless Entry system, a power tilt/telescoping steering column with increased travel, illuminated glove compartment and automatic temperature control. Also standard is XM® Satellite Radio (XM® subscription required, sold separately) and Rear Sonar System.

    An Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt sensors and occupant classification sensor is standard, along with door-mounted curtain side-impact supplemental air bags, front-seat mounted side-impact supplemental air bags and front seat Active Head Restraints. The rear seat includes fixed head rests with rear Pop-up Roll Bars. The G Convertible also features reinforced front side members, front pillars and body sills.

    “With it’s pure IPL style and performance, and the added dimension of open-air motoring, the IPL G Convertible is a welcome addition to the Infiniti Performance Line lineup,’” added Poore. “Watch for more models joining the IPL lineup in the future.”

    The 2013 IPL G Coupe is offered in one fully equipped model, the IPL G Convertible with 7-speed automatic transmission. There are no options.

    If your coming from the original G35 Sedan and Coupe, then the answer is yes

    If your coming from a couple year old G37 Sedan/Coupe, then the answer is maybe/no

    I had a rental G37 earlier this year. The interior had good fit and finish, everything fit together tightly. But the dash materials were nothing special, same rubbery/plastic stuff any car has, the metal trim looked real though. The leather was nice, similar to a Lexus. The CTS interior has more style and more going on, the Infiniti is simpler, sort of plain. The G37's party piece is the engine, the car can be a bit herky-jerky at low speed because it has a touchy throttle and brakes but when you want to go fast this car shines and that engine will rev to 7,000 or so rpm with ease. The problem with the G37 is it is good in sport driving, but not at much else, where as a BMW can do the smooth part and the sporty part, the G37 is rough around the edges car.

    But on the IPL model, why is it only 15 more hp? When you get an AMG or M car it is like 100 more hp. If they are going to do IPL, then this car should have 400 hp turbo or something.
