2011 INFINITI G Coupe Press Kit: Overview

When it comes to a pure, seductive expression of intense performance, many INFINITI vehicles likely come to mind. But perhaps none embodies the idea of "Inspired Performance" better than the INFINITI G Coupe – which is designed to stir the soul through an unmatched combination of dynamic design, exhilarating performance and a modern, luxuriously crafted interior. And, if all that isn't enough, the G Coupe enters 2011 with a number of enhancements including new wheel design, new seductive colours and a redesigned front fascia.

In addition to the two exciting INFINITI IPL G Coupe models, the G Coupe is offered in four exciting models: G37 Coupe, G37 Coupe Sport, G37S Coupe Sport 6MT and G37x Coupe AWD – each equipped with a standard 3.7-litre VQ-series V6 with VVEL (for Variable Valve Event and Lift) rated at 330 horsepower and 270 lb-ft of torque. Three models are offered with a standard performance-oriented 7-speed automatic transmission with Drive Sport (DS) Mode, Downshift Rev Matching and available solid magnesium paddle shifters. The G37 Coupe Sport 6MT comes with a responsive, close-ratio 6-speed manual transmission.

Enhancements for the 2010 model year are primarily concentrated inside the beautiful G Coupe body. The previous "Washi" aluminum trim is replaced by a new "Shodo" style trim, inspired by the traditional art of Japanese calligraphy, on all models. Other changes include the addition of standard 8-way power passenger seats on all models, a new centre console design on automatic transmission-equipped models and a number of package content changes, such as the addition of the Advanced Climate Control System (ACCS) with Plasmacluster™ air purifier to the Technology Package and making RearView Monitor standard on all models.

"Our goal is to always keep moving ahead, always keep our vehicles fresh with new designs and new technologies," said Wendy Durward, Director, INFINITI Canada. "There's no better example of this philosophy than the enhanced 2010 G line."

Highly Seductive Styling
As the G37 Coupe enters the third year of its second-generation design, its stunningly seductive styling is recognized around the world. The smooth, aerodynamic design offers a kinetic feeling with an emotional surface expression, while the sweeping character lines and tight panel gap lines provide a rich, high quality appearance. Exterior highlights include flowing front fender curves, a wave-style hood, expressive front fascia with INFINITI's signature double-arch grille and L-shaped High-Intensity Discharge (HID) bi-functional Xenon headlights with integrated fog lamps.  The strong side character line and side sills integrate with the large wheel wells and performance-oriented wheel and tire packages to transmit an added sense of power and vibrancy. The rear of the G37 Coupe features broad rear fenders flowing into the large LED taillights, refined rear bumper, integrated RearView Monitor camera (when equipped), rear underbody air diffusers and large dual exhaust outlets with chrome finishers.

The G37 Coupe Sport 6MT models and G37 with Sport Package add an enhanced performance look, with a unique front fascia, special side sills and standard 19-inch aluminum-alloy wheels with high performance tires.

Eight exterior colours are offered for 2010: Plasma Red, Athens Blue, Platinum Ice, Liquid Metal Grey, Blue Onyx, Black Obsidian, Aspen Pearl and the new Asgard Grey.

Sophisticated, Luxurious Interior
The 2010 G37 Coupe interior design again features sophisticated craftsmanship, with a cockpit-oriented front driver and passenger area, INFINITI signature "double wave" instrument panel design featuring the INFINITI-signature analog clock and dramatic, full-length centre console with a leather and aluminum-clad shifter. The new Shodo aluminum-alloy interior trim is featured on the instrument panel, centre console and door panels.

The instrument panel includes INFINITI electroluminescent instrumentation with new white illumination and integrated multi-function information drive computer display (average fuel consumption, real-time fuel economy, average speed, elapsed time, running distance, distance to empty, outside air temperature, warning displays, odometer and automatic transmission shift indicator).

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 available for the 7-speed automatic transmission (G37 Coupe with Sport Package only). The 8-way power driver and front passenger seats are appointed with INFINITI's exclusive premium leather and 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 G37 Coupe Journey with Sport Package and G37 Coupe Sport 6MT add special sport-styled seats with thigh extensions and power adjustable torso and thigh bolsters for the driver, unique steering wheel stitching and high-grip aluminum pedals.

Technological and convenience features abound in the G37 Coupe, including 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 a 7-inch colour display and standard XM® Satellite Radio (XM® subscription required, sold separately). Standard is an 11-speaker INFINITI "Studio on Wheels"™ by Bose® with a 3-way front door speaker array using 10-inch woofers.

The G Coupe's available INFINITI Navigation System has been enhanced with next generation technology and a new display screen with four times the resolution of the previous generation system's screen. New features include Streaming Audio via Bluetooth® and Zagat® Restaurant Guide. The system also includes touch screen and 9.3GB Music Box Hard Drive

Three interior colour combinations are offered – Wheat, Graphite and Stone. Both the Wheat and Stone interior colours have been revised for 2010 to provide a more neutral colouring.

Exhilarating Performance, Intuitive All-Wheel Drive
At the core of the G Coupe's stellar performance is its advanced 3.7-litre VQ37VHR V6 engine with VVEL (for Variable Valve Event and Lift) rated at 330 horsepower and 270 lb-ft of torque. The VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response. The VVEL intake camshafts, featuring continuously variable lift control teamed with the Continuously Variable Valve Timing Control System (CVTCS), allow for a 7,500 rpm redline.

The engine also features increased cylinder block height (from the previous 3.5-litre design), ladder frame construction for greater rigidity, large crank journal and pin diameters, asymmetric piston skirts, twin knock sensors, an electronically controlled "drive-by-wire" throttle system, lightweight pistons, Iridium spark plugs and a symmetric twin air intake system.

The specially tuned dual exhaust system features equal length exhaust manifolds and low muffler exhaust backpressure to help improve engine breathing. Both intake and exhaust enhance driving pleasure with their authentic performance notes.

"The G Coupe's 3.7-litre V6 is a true powerhouse – becoming more enjoyable as you drive it," said Durward. "The engine also features INFINITI's distinctive ‘Swell' acceleration – with special tuning that builds horsepower almost continually to the redline like a building wave."

The G37 Coupe engine is backed by a choice of an electronically controlled 7-speed automatic transmission with manual mode, downshift rev matching, Drive Sport (DS) mode and Adaptive Shift Control (ASC) that allows for quicker shifts in sporty driving situations and available solid magnesium paddle shifters; or a responsive, lightweight 6-speed manual transmission.

The foundation for the G Coupe's impressive handling and ride performance comes from its second-generation FM (Front Mid-ship) platform. The 4-wheel independent suspension design features lightweight aluminum components and large front and rear stabilizer bars.
The front suspension is a double-wishbone design, with a single pivot lower wishbone and a long upper link, while the multi-link rear suspension separates the shock absorbers and springs, locating the shock absorber inline with the wheel centre. These designs help minimize alignment changes and reduce suspension friction for nimble handling and smooth riding characteristics.

Responsive steering is provided by a vehicle-speed-sensing design, which provides optimum steering effort at both high and low vehicle speeds. Standard on all G37 Coupes is Vehicle Dynamic Control (VDC), which assists in enhancing vehicle stability under a variety of driving conditions.

For buyers looking for the added control and all-climate handling of all-wheel drive, the G37x Coupe AWD comes with INFINITI's advanced ATTESA E-TS™ (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system. The system utilizes an active torque distribution management system with an active centre clutch designed for smooth starts and better traction and maneuverability on snowy roads than conventional all-wheel drive systems, plus minimal compromise of rear-wheel drive performance characteristics on dry roads.

Monitoring wheel spin, throttle position and vehicle speed, it automatically diverts up to 50 percent of available power to the front wheels, enhancing traction and control when road conditions are less than optimal. When all-wheel drive is not needed, the system can send up to 100 percent of the power to the rear wheels, preserving the G's sporty rear-wheel drive characteristics.

Braking performance is provided by standard 4-wheel vented discs with 4-channel, 4-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist. The G37 Coupe with Sport Package and G37 Coupe Sport 6MT are further enhanced with aluminum four-piston calipers (front)/two-piston calipers (rear) embossed with INFINITI lettering and large ventilated rotors – 14.0-inch front and 13.8-inch rear.

Also available on G37 Coupe is INFINITI's Intelligent Cruise Control (ICC) with Preview Braking, which provides a precise following distance from the vehicle ahead. It also identifies sudden braking situations with laser sensors to determine distance and relative speed of the vehicle ahead in the same lane and "pre-pressurizes" the Brake Assist system before the driver steps on the brake pedal.

Split 5-spoke 18-inch aluminum-alloy wheels with P225/50VR18 all-season tires are standard on G37 Coupe.    A Tire Pressure Monitoring System (TPMS) is standard on all 2010 G37 Coupes.

Enhancing the already high level of dynamic performance of the G37 Coupe 6MT and G37 Coupe with Sport Package are a unique sport suspension, a Viscous Limited Slip Differential (VLSD) and 19x8.5-inch front wheels with P225/45WR19 front tires and 19x9.0-inch rear wheels with P245/40WR19 rear tires.

Safety Performance and Technology
Every 2010 G37 Coupe is available with 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 G37 Coupe features Zone Body Construction with front and rear crushable zones to help disperse crash energy around the passenger compartment.

For occupant safety, the engine is designed to move under the occupant compartment in a high-speed frontal collision, while a breakaway construction of the propeller shaft (connected with the engine-drop function) and the double-wall construction of the bulkhead helps to minimize cabin deformation, especially in the lower leg area. In addition, the brake pedal is designed to collapse to help reduce lower leg injuries in a severe crash.

Four Well-Equipped Models
The 2010 INFINITI G37 Coupe is available in four models: G37 Coupe, G37 Coupe Sport, G37 Coupe Sport 6MT and G37x Coupe AWD.

Standard is the Premium Package, which includes  a power sliding glass moonroof, 11-speaker INFINITI "Studio on Wheels"™ by Bose® audio system, 2.0GB Music Box, memory system (drivers seat, steering wheel and outside mirrors) with synchronization, driver's seat power lumbar support, power tilt and telescoping steering wheel and Rear Sonar System.

Also available is the Sport Package (available on G37 model and standard on G37 Coupe Sport 6MT), which includes 19-inch wheels and high-performance tires, Viscous Limited-Slip Differential (VLSD), sport-tuned suspension, sport brakes, unique front fascia and side sills, sport-styled seats and steering wheel stitching, aluminum pedals and paddle shifters (G37 Coupe only).

The INFINITI Navigation Package adds navigation system with 08IT technology, WVGA display screen,  Streaming Audio via Bluetooth® and Zagat® Restaurant Guide, touch screen and 9.3GB Music Box Hard Drive.

The Technology Package includes INFINITI Intelligent Cruise Control (ICC) with Preview Braking, "Pre-Crash Seatbelt" system, rain-sensing windshield wipers and Advanced Climate Control System (ACCS).

"INFINITI Performance Line(TM)" Launches With Dramatic New 348-Horsepower IPL G Coupe

INFINITI today announced its rumored specialty-performance vehicle collection, the INFINITI Performance Line™. The first production vehicle from this group, the 348-horsepower 2011 INFINITI Performance Line G Coupe, debuts tomorrow evening at an exclusive event at the 60th annual Pebble Beach Concours d’Elegance. It joins the INFINITI line of performance luxury vehicles at INFINITI retailers nationwide in December.

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 2011 IPL G Coupe is the first of what is expected to be a range of IPL performance vehicles in the future.

INFINITI Performance Line vehicles are targeted at buyers seeking performance luxury vehicles that express a greater degree of individual style. The limited production IPL vehicles begin with INFINITI’s legendary emotional design and Japanese craftsmanship – and then heighten the luxury and performance levels through modifications to the exterior, interior, engine tuning and suspension.

“IPL was conceived to create a new premium performance envelope, going beyond equipment upgrades to accelerate the very soul of INFINITI’s Inspired Performance,” said INFINITI Vice President Ben Poore. “IPL brings all the elements together, styling harmonized with performance, exhaust note with acceleration feel, ride comfort and confident handling. It’s the perfect formula for unmatched driving exhilaration.”

IPL models will be identified by a special engine cover and trunklid badging. The IPL emblem is designed to reinforce the strong message and spirit of IPL. The letter “I” features a red insert representing sporty spirit, while the INFINITI-violet “shadow” behind the letter appears like an INFINITI flag to indicate the brand’s Inspired Performance promise.

About the IPL G Coupe
The 2011 IPL G Coupe builds on the foundation of the second-generation INFINITI G Coupe 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 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 RE50A 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.

Other standard interior features include INFINITI Studio on Wheels by Bose® premium audio system, INFINITI Hard Drive Navigation System, 9.3GB Music Box® Hard Drive, INFINITI Voice Recognition for audio navigation, memory system for driver’s seat, steering wheel and outside mirrors, RearView Monitor, Rear Sonar and moonroof (these items are optionally available on non-IPL G Coupe models).

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-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.

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. 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).

“When you drive the IPL G Coupe, the first thing you notice is the surge in sound and acceleration feel. The inspiring swell of sound is in complete harmony with the acceleration feel as engine speed increases,” said Poore. “The sound is clean and inspiring, adding to the fun-to-drive sensation provided by the 348 horsepower under the hood.”

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 removing 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 to reach a new premium performance standard.

The IPL G Coupe also offers a sport-tuned steering gear and large 4-wheel sport brakes with aluminum-alloy opposed calipers (4-piston front/2-piston rear) and Viscous Limited-Slip Differential (VLSD).
