Following the 2011 expansion of the G Sedan Line with the introduction of the 2.5-liter V6-equipped Infiniti G25 Sedan and the specially equipped G37 Limited Edition and Special Appearance models, there are now 10 ways to enjoy the uniquely exhilarating performance luxury sedan experience known as the G Sedan.
The major enhancements for the 2012 model year focus on content refinements to the Limited Edition and Sport Appearance Edition models. The G37 Limited Edition adds a new Graphite interior color (replaces the previous Monaco Red interior), a Black Obsidian exterior color and dark-finish 18-inch aluminum-alloy wheels. The G37 Sport Appearance Edition model changes include a new Midnight Black grille. Other 2012 refinements include one new exterior color, Malbec Black, for all models (excluding G25, Limited Edition and Sport Appearance Edition).
The full 2012 Infiniti G Sedan lineup includes the G25 Sedan, G25 Sedan Journey, G25x Sedan AWD, G37 Sedan Journey, G37x Sedan AWD, G37 Sedan Sport 6MT, G37 Sedan Sport Appearance Edition, G37x Sedan AWD Sport Appearance Edition, G37 Sedan Limited Edition and G37x Sedan AWD Limited Edition.
The Infiniti G25 Sedan
The addition last year of the G25 Sedan, with its more value-based price point, broadens the G’s appeal by providing an additional choice for buyers looking for a true luxury sedan – but who might not need the higher levels of performance provided by the larger engine-equipped G37 models. The G25 Sedan shares the same dynamic exterior, interior and chassis as the G37, but with a smaller displacement engine. The refined 2.5-liter DOHC 24-valve V6 produces 218 horsepower and 187 lb-ft of torque.
The G25 Sedan comes with a standard 7-speed automatic transmission and is available in both rear-wheel drive and intelligent all-wheel drive. Three G25 Sedan models are offered: G25 Sedan, G25 Sedan Journey and G25x Sedan AWD.
The G25 Sedan’s extensive list of standard equipment includes leather-appointed seating, Shodo aluminum interior trim, 8-way power driver’s seat and 4-way power front passenger’s seat, Automatic Temperature Control, premium audio system with six speakers, XM® Satellite Radio (XM® subscription required, sold separately) and much more. Other standard G25 Sedan features range from 17-inch aluminum-alloy wheels and High Intensity Discharge (HID) xenon headlights to 4-wheel Anti-lock Braking System (ABS), Vehicle Dynamic Control (VDC) and Traction Control System (TCS).
Across the Line – Inspired, Sporty Styling
For 2012, both G25 and G37 models retain the signature visually striking G exterior design, with its long, wave-like hood, raked A-pillars and athletic stance projecting a balance of power and grace that is suggestive of the performance potential within. The front of the G Sedan is highlighted by its iconic headlight and grille design, which offer a crisp form and high quality feel. Standard fog lights are located in the lower fascia, where they help provide an upscale and distinctive appearance. Every G offers standard High Intensity Discharge (HID) bi-functional xenon headlights. The silhouette offers a wedged roofline and a sweeping bodyside character line that emphasizes both the rich shoulder surfaces and the G’s rear-wheel drive orientation. The G37 Sport Sedan 6MT model features distinctive front fascia, headlights and sport side sills – which are also available as part of the Sport Package.
In the rear, the refined, evolutional L-shaped LED taillights express the G heritage and the Infiniti design identity. The trunk lid is accented by an integrated chrome spoiler, while prominent dual exhaust outlets complete the sporty appearance.
Eight exterior colors are offered for 2012: Vibrant Red, Liquid Platinum, Smoky Quartz, Graphite Shadow, Blue Slate, Black Obsidian, Moonlight White and Malbec Black.
A Refined Interior With a Crafted, Quality Feel
Every G Sedan offers a crafted interior environment with a long list of standard or available luxury features, such as standard leather-appointed seating and “Shodo” aluminum trim inspired by a style of Japanese calligraphy. An available audiophile-quality Infiniti Studio on Wheels by Bose premium audio system, which combines Bose’s 3-way speakers using 10-inch subwoofers in the front doors with a parcel shelf-mounted subwoofer in the rear. The instrument panel offers a predominately white color scheme for the gauge and LCD instrument display, enhancing both legibility and cohesiveness of design. In keeping with tradition, a refined analog clock is standard on all G25 and G37 models.
The 2012 G Sedan interior also continues to provide an unmatched harmony between the dedicated driver’s cockpit and comfortable passenger space – and between modern technology and traditional Japanese design cues. The result is a “modern warmth” that is unique in the sport sedan segment. The driver’s area has a simple, intuitive layout with easy-to-read electroluminescent gauges. A center information display, located between the tachometer and speedometer, conveys updates from the drive computer (average fuel consumption, instantaneous fuel economy, average speed, elapsed time, running distance, distance to empty, outside air temperature, warning displays, odometer and automatic transmission shift indicator).
The G’s available Infiniti Navigation System includes a high-resolution display screen. Along with the XM NavTraffic® Real-Time Traffic Information, the navigation system includes NavWeather™ with Real-Time Weather and 3-day forecast (XM® subscription required, sold separately), Streaming Audio via Bluetooth® and Zagat Survey® Restaurant Guide. The system also includes a touch screen and Voice Recognition. Other technologies include standard Infiniti Intelligent Key with Push Button Ignition, standard 7.0-inch color monitor display, standard XM® Satellite Radio (XM® subscription required, sold separately), and available RearView Monitor, Bluetooth® Hands-free Phone System and Brake Assist with Preview Braking (Intelligent Cruise Control).
Powerful, Responsive 3.7-liter V6 Performance
While the G25 Sedan’s standard 2.5-liter V6 provides outstanding levels of horsepower and torque, the G37’s stands out in class with it advanced 3.7-liter VQ37HR V6 with VVEL.
Rated at 328 horsepower and 269 lb-ft of torque, the engine’s VVEL (for Variable Valve Event & Lift) 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 system also offers improved emissions and fuel efficiency over the non-VVEL designs. The VVEL intake camshafts, featuring continuously variable lift control teamed with the Continuously Variable Valve Timing Control System (CVTCS), allow for a 7,600 rpm redline.
The engine also features rigid ladder frame construction, large crank journal and pin diameters, asymmetric piston skirts, twin knock sensors, an electronically controlled “drive-by-wire” throttle system, coated 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.
To help take full advantage of both refined engine designs, the G25 and G37 Sedans come with a standard (except for the G37 Sport 6MT model) 7-speed automatic transmission with Downshift Rev Matching, Drive Sport mode and ASC (Adaptive Shift Control) that allows for sportier shifts in performance driving situations. Solid magnesium paddle shifters are standard on G37 Limited Editions and as part of the Sport Package for G37 Journey and G37x AWD models. The G37 Sport 6MT features a smooth-shifting, close-ratio 6-speed manual transmission.
Estimated fuel economy for G25 Sedan RWD models is rated at 20 mpg City and 29 mpg Highway and 19 mpg City/27 mpg Highway for the G25x Sedan AWD model (all models equipped with the 7-speed automatic transmission).
Estimated fuel economy for the G37 Sedan RWD is rated at 19 mpg City and 27 mpg Highway with the 7-speed automatic transmission and 17 mpg City/25 mpg Highway with the 6-speed manual transmission. Fuel economy for G37x AWD models is estimated at 18 mpg City/25 mpg Highway.
Every G Sedan is equipped with the advanced FM platform, which locates the engine behind the front axle in the “Front Mid-ship” position. The positioning of the engine provides good front-to-rear weight balance, while the combination of long wheelbase, manageable overall length and wide front and rear track adds to the G Sedan’s overall handling performance. The G Sedan’s suspension is a 4-wheel independent design with lightweight aluminum components and front and rear stabilizer bars, designed to provide nimble and natural feeling handling, as well as a controlled, refined ride. The front suspension minimizes alignment changes through use of a single pivot lower wishbone and a long upper link. The rear suspension design separates the shock absorbers and springs, locating the shock absorber inline with the wheel center to help reduce suspension friction and reduce the wind-up motion of the axle on acceleration.
The Infiniti G37 Sport 6MT, G37 Journey RWD models with the optional Sport Package and G37 Limited Edition RWD include a sport-tuned suspension and 14.7:1 sport-tuned steering gear. All G37x Sedan AWD models feature Infiniti’s state-of-the-art ATTESA E-TS? (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system. The electromagnetic AWD system responds more quickly and precisely than conventional hydraulic AWD systems, with minimal compromise of rear-wheel drive performance characteristics on dry roads.
In addition, Vehicle Dynamic Control (VDC) is standard on all models, while Viscous Limited Slip Differential (VLSD) is included on the G37 Sport 6MT, G37 Journey RWD Sport Package-equipped vehicles and G37 Limited Edition RWD.
The G’s brake system utilizes power-assisted 4-wheel vented disc brakes with 4-channel, 4-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). Larger Sport Brakes (14.0-inch front, 13.8-inch rear) with 4-piston front/2-piston rear calipers are standard on the G37 Sport 6MT, the G37 Journey with Sport Package and G37 Limited Edition RWD. Also available is a Brake Assist with Preview Braking system (with Intelligent Cruise Control). The power steering system is a vehicle-speed-sensing design, which balances steering effort at both high and low speeds.
The G25 features a standard 17-inch aluminum-alloy wheel design with painted finish and P225/55R17 tires. Infiniti G37 models are available with a number of different aluminum-alloy wheel designs, including split 5-spoke and split 7-spoke 18-inch designs, and both all-season and W-rated summer performance tires (with the sport 5-spoke wheels only).
All 2012 G25 and G37 Sedans come equipped with Infiniti’s Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt sensors and occupant classification sensor, along with front seat-mounted side-impact supplemental air bags and roof-mounted curtain side impact supplemental air bags for front and rear-seat outboard occupant head protection.
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, front seat Active Head Restraints and the LATCH System (Lower Anchors and Tethers for CHildren). Brake-Operated Pre-Crash Seat Belts are available as part of the G37 Technology Package. Every G Sedan also features Zone Body Construction with front and rear crumple zones to help disperse crash energy around the passenger compartment.
