2011 IPL G Coupe Debuts With 348-Horsepower 3.7-liter V6, Tuned Suspension and Exclusive Exterior and Interior Features

Infiniti enters the 2011 model year with an impressive slate of all-new or refreshed products, including the next generation Infiniti M performance luxury sedan and Infiniti QX full-size luxury SUV. The most memorable addition of all, however, might be the introduction of the new specialty-performance vehicle collection, the Infiniti Performance Line.

The Infiniti Performance Line, or IPL, offers a new level of premium performance for Infiniti vehicles, focusing not just on engine power and acceleration, but also on redefining total vehicle performance. IPL promises unique driving attributes with exclusive designs, different from other Infiniti models in each selected Infiniti line. The first production vehicle in what is expected to be a range of IPL performance vehicles in the future is the 348-horsepower 2011 Infiniti Performance Line G Coupe.

"The 2011 IPL G Coupe sets a new performance standard, bringing all the elements together - styling harmonized with performance, exhaust note with acceleration feel, ride comfort and confident handling," said Infiniti Vice President Ben Poore. "It's the perfect formula for unmatched driving exhilaration."

Introducing the IPL G Coupe
The 2011 IPL G Coupe builds on the foundation of the second-generation Infiniti G Coupe Journey rear-wheel drive model with extensive modification throughout the vehicle. The IPL G Coupe's unique exterior includes a dramatic front and rear bumper/fascia design with integrated fog lights and black finishers, sculpted side sills, rear spoiler and round chrome exhaust tips.

Each part is shaped to accent the G Coupe's aggressively 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 Coupe projects a confident stance and road-ready attitude. The IPL G Coupe is offered in just two exterior colors: Graphite Shadow and Malbec Black.

The IPL G Coupe interior is designed to harmonize with the exterior styling, offering two color treatments - Graphite and Monaco Red (red interior only available with the Malbec Black exterior and 7-speed automatic transmission).

All IPL G Coupe interiors include red-stitched leather-appointed front sport seats with manual thigh extension and driver's power torso and thigh support adjustment, red-stitched steering wheel, Silk-Obi aluminum trim, and aluminum pedals and footrest. The 8-way power driver and front passenger seats feature 2-way adjustable head restraints and a unique rear-seat access system (the front seats move forward automatically at the touch of a button to allow passengers into the rear seats).

The double hand-stitched leather-covered steering wheel is designed for maximum comfort and usability, with standard wheel-mounted audio and cruise controls. Solid magnesium paddle shifters are standard with the 7-speed automatic transmission.

Other standard interior features include Infiniti Voice Recognition for audio navigation, memory system for driver's seat, steering wheel and outside mirrors, RearView Monitor, Rear Sonar and sliding glass panel moonroof.

The IPL G Coupe's enhanced performance comes from the synergetic effects of three technology areas - engine tuning, dynamic tuning, and sound quality/acceleration feel tuning. Engine performance modifications were selected not only for increased horsepower and torque levels, but also for acceleration feel and exhaust sound without compromising fuel economy or noise standards.

The IPL G Coupe's advanced VQ37HR 3.7-liter V6 engine management system has been recalibrated through air-fuel mixture and ignition timing optimization, raising the maximum horsepower output point to 7,400 rpm (from 7,000 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 Coupe's Y-pipe exhaust system design.

As a result of both the exhaust system and engine management changes, the IPL G Coupe generates 348 horsepower - an increase of 18 horsepower over the non-IPL models - and 276 lb-ft of torque (+6 lb-ft).

Equally inspiring is the IPL G Coupe's dynamic vehicle performance, which 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 increased 20% over the base G Coupe and rear spring rates increased 10%. Shock tuning has also been adjusted.

The IPL G Coupe 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) and Viscous Limited-Slip Differential (VLSD).

Technological and convenience features include standard Infiniti Intelligent Key with Push Button Ignition, Remote Keyless Entry system, a 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 an 11-speaker Infiniti "Studio on Wheels" by Bose with a 3-way front door speaker array using 10-inch woofers.

The IPL G Coupe's standard Infiniti Navigation System features XM NavTraffic Real-Time Traffic Information, XM NavWeather with Real-Time Weather and 3-day forecast (XM subscription required, sold separately), and Zagat Survey Restaurant Guide. The system also includes touch screen and 9.3GB Music Box Hard Drive.

Every 2011 IPL G Coupe offers a long list of standard safety and security features, including an Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt and occupant classification sensors is standard, roof-mounted curtain side impact supplemental air bags for front and rear-seat outboard occupant head protection and front seat-mounted side impact supplemental air bags.

Also standard are 3-point ALR/ELR seat belts (driver's side ELR only) and front seat belts with pretensioners and load limiters and adjustable upper anchors, driver and front-passenger knee bolsters, front seat Active Head Restraints and the LATCH System (Lower Anchors and Tethers for CHildren). Available as part of the Technology Package are brake-operated pre-crash seat belts with motion sensor on the brake pedal.

The 2011 IPL G Coupe is available in two fully equipped models: IPL G Coupe and IPL G Coupe 6MT. There are no options.
