"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 Infiniti 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 Infiniti 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 Infiniti 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 Infiniti 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 Infiniti 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.
