The Infiniti G37 is Infiniti's new sports car that is expected to replace the Infiniti G35 Coupe for 2008. The G37 was unveiled at the 2007 New York International Auto Show.
EXTERIOR: The 2008 G37 maintains many of the styling cues from the previous G35 coupe model, however every sheet metal body panel is new. The exterior includes the Infiniti signature "L" bi-xenon headlights, LED taillights, and double arch grill. Also new are a wave hood and integrated rear lip spoiler, character line running from the front wheel well to the rear and side sills. Available sliding moonroof, and heated outside mirrors. Base wheels are 18x8 inch aluminum split 5-spoke wheels and optional are 19x8.5 inch 10-spoke wheels. Eight exterior paint colors will be available. Colors confirmed through photographs: red, silver.
INTERIOR: The interior of the production G37 is all new, and appears to be closely tailored after the interior used in the 2007 G35 sedan. Available features include: a touch-screen navigation system with XM NavTraffic real-time traffic function, a 9.3-gigabyte Music Box hard drive, a rear-view monitor, Bluetooth, Infiniti Intelligent Key with Push Button Ignition, and an 11-speaker Infiniti "Studio on Wheels" audio system by Bose. 8 way power driver seat and 4-way passenger is standard with 8-way passenger, sport-styled seats with thigh extensions, and driver's power adjustable torso and thigh bolsters optional. Leather seating is standard in a choice of three colors: wheat graphite or stone.
ENGINE: A new engine, identified as VQ37VHR, replaces the 3.5 liter engine used in the previous coupe model and the current G35 sedan. The 3.7 liter DOHC 24-valve V-6 powerplant produces 330 HP and 270 lb-ft of torque(24 hp and 2 lb-ft improvements over the current 3.5 liter G35 engine) with a 7,500rpm redline. Early dynamometer readings conducted during a magazine test indicate that the G37 manual transmission produces 287 hp and 236 ft-lbs. of torque at the rear wheels (compared to 236 hp and 218 ft-lbs. of torque in the previous six-speed coupe model). The engine uses an 86-mm stroke (up from 81.4 mm on the previous model) and a compression ratio of 11.0:1 (up from 10.6 on the previous model). This is also the first engine to use Nissan’s Variable Valve Event and Lift (VVEL) technology, which improves the torque curve and fuel economy, in a manner similar to BMW's valvetronic system, but is simpler and lighter in design, thus allowing the engine to have a high redline of 7,500rpm. Other engine related additions include Ram air dual intake, equal length exhaust manifold and dual exhaust system with laser-welded rear mufflers. Early announcements by Nissan guess that fuel mileage will be improved 2 miles per gallon over the previous G35 coupe model, but final numbers have not yet been released.
TRANSMISSION: The gearbox options are a 6 speed manual or a 5 speed automatic.The five speed automatic maintains the use of a torque converter, and with manual shift options through use of the console mounted gear lever and available magnesium shift paddles mounted behind the steering wheel.
CHASSIS: The vehicle is built on Inifiniti's second generation FM platform and is 36% more rigid that the previous G35 coupe model. Vehicle dimensions are 183.1 inches long, 71.7 inches wide, and 54.7 inches tall. Precise measurements are unknown at this time, however, Nissan states that the G37's suspension has higher spring rates, larger sway bars, and stiffer damping characteristics that the 2007 G35 Sedan. The front suspension uses double-wishbone unit with a single lower ball joint and the rear suspension is a multilink design. The Base G35 rides on stock 18 inch wheels wearing 225/50 Dunlop tires, with 13.0-inch brakes at all four wheels, and a 16.4:1 steering ratio. The optional sport package includes 19-inch wheels wearing 225/45 front and 245/40 rear Bridgestone tires, fourteen-inch rotors with four-piston front calipers, 13.8-inch rotors with two-piston calipers in back, and a 14.7:1 steering ratio. Note that the optional sport package uses Akebono sourced brakes, replacing the previous models Brembo units. Also optional, in the Premium package, is "4WAS" or four-wheel active steering, which can add up to one degree of steering input from the rear wheels, effectively reducing the steering ratio depending on speed and multiple vehicle sensor inputs. Only the 6MT and sport package models will be equipped with a limited-slip rear differential, and limited-slip will not be available on the base model. Vehicle Dynamic Control (VDC) is standard as are 4-wheel power-assisted vented disc brakes, 4-wheel Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). Available options include Intelligent Cruise Control (ICC) with Preview Braking. Safety features include
AVAILABILITY & PRICING: The current release date is slated as August 21, 2007 for first dealer delivery. Three models will be available: G37 Coupe, G37 Coupe Journey and G37 Coupe Sport 6MT models. Pricing has not yet been announced, but is estimated to be between $34,000 and $38,000 depending on trim level. The previous model G35 Coupe started at a base price of $33,500. The same vehicle will be available in Japan under the Nissan Skyline nameplate.
RUMORS: Rumors have also been circulating regarding a Twin Turbo version of the G37, which may be released in 2010. If released, it will probably have around 500 horsepower, and be all-wheel-drive. The reasoning behind this rumor is that Infiniti has expressed discontentment that the most expensive, highest performing Nissan vehicle, the GT-R, is anticipated to be released exclusively under the Nissan badge.
