All-New 2008 Infiniti G37 Coupe Sets New Standards For Style, Performance and Luxury
Highlights Include New 330 Horsepower V6, Seductive Styling and Luxury Appointments
The all-new 2008 Infiniti G37 Coupe combines the exhilarating performance, stunning styling and modern, sporty interior of the original Infiniti G Coupe and accelerates each to new levels. Among the key enhancements to the new second-generation G Coupe are a larger, more powerful 3.7-liter V6 engine, available advanced 4-Wheel Active Steer system, a dramatic new exterior design and a refined interior with intuitive, integrated technology. The G37 Coupe joins the recently introduced, all-new 2007 Infiniti G35 Sedan in Infiniti showrooms nationwide in August.

"The new G35 Sedan, which has been named to both Car and Driver’s "10 Best Cars" and Automobile magazine’s "All-Stars" list, has set the stage for the introduction of the new G37 Coupe," said Mark Igo, vice president and general manager, Infiniti Division. "The new Coupe builds on the styling, performance and interior enhancements of the G Sedan, adding the dynamic style, sporty atmosphere and expressive driving character expected of a class-leading luxury sport coupe. The line starts here."
Exhilarating Performance From a New Engine Leading the enhancements to the 2008 Infiniti G37 Coupe is the first-ever application of the new 3.7-liter V6 engine with VVEL (for Variable Valve |
Both the Coupe’s VQ37VHR and the Sedan’s VQ35HR engines are based on the award-winning VQ engine series, named one of the “Ten Best Engines” by Ward’s Auto World magazine for 13 consecutive years.
Along with utilizing a larger displacement than the previous 3.5-liter powerplant, the G37 Coupe’s new 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 system is also expected to improve emissions and fuel efficiency. 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-liter 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, molybdenum coated lightweight pistons, Iridium spark plugs and a symmetric twin air intake system.

A new, specially tuned dual exhaust system has been designed with 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.
Rated at 330 horsepower, the new engine is not only considerably more powerful than the previous generation G Coupe (rated at 275 hp with 5AT, 293 hp with 6MT), but is expected to offer increased fuel mileage and reduced emissions levels. Overall vehicle fuel economy improvements are estimated to be nearly one mpg |

“The new 3.7-liter V6 is a true powerhouse – becoming more enjoyable as you drive it,” said Igo. “And, this powerplant also features Infiniti’s trademark “Swell” acceleration – introduced on the new G Sedan last year – 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 upgraded electronically controlled 5-speed automatic transmission with manual mode, downshift rev matching, DS mode and ASC (Adaptive Shift Control) that allows for quicker shifts in sporty driving situations and available genuine magnesium paddle shifters; or a newly revised, lightweight 6-speed manual transmission.
Performance Platform and Suspension
Developed at test circuits throughout Europe – including the famed Nürburgring – the G37 Coupe was conceived as a performance thoroughbred. Handling and ride performance increases come from the G37 Coupe’s enhanced FM (Front Mid-ship) platform, which has been stiffened 36% from the previous generation, is lower in overall height and has a wider front and rear track width.
The G37 Coupe’s 4-wheel independent suspension design features lightweight aluminum components and large front and rear stabilizer bars, increased spring rates and optimized suspension damping.
The front suspension is a double-wishbone design, with a single pivot lower wishbone and a long upper link. The multi-link rear suspension separates the shock absorbers and springs, locating the shock absorber inline with the wheel center. These designs help minimize alignment changes and reduce suspension friction for nimble handling and smooth riding characteristics.
Steering is provided by a twin-orifice 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.
Also available on the new G37 Coupe is Infiniti’s exclusive 4-Wheel Active Steer system (4WAS). With unique chassis configuration that features automatically variable front steering ratios and rear suspension geometry that adjusts to steering input and vehicle speed via motor-driven controls. The system’s electronic control unit calculates the desired vehicle dynamics from a series of sensors, including vehicle speed and steering angle, and separately directs both the front and rear actuators to change steering gear ratios and rear geometry by moving both the front steering gear and rear suspension lower links – thus providing sports car-like agility and secure stability.
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 (BA). The standard G37 Coupe adopts the “sport” braking system of the recently introduced G35 Sedan. The G37 Coupe Journey 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.

A new 18-inch wheel and tire package is standard on G37 Coupe, featuring a “split 5-spoke” 18x8-inch aluminum-alloy wheel design with P225/50VR18 all-season tires. A new 10-spoke 19-inch wheel and tire package, with lightweight cast aluminum wheels and high performance tires, is also available. A Tire Pressure Monitor System (TPMS) is standard on all 2008 G37 Coupes.
To enhance the already high level of dynamic performance, the G37 Coupe 6MT and G37 Coupe Journey with Sport Package come standard with |
Seductive Styling
The G37 Coupe’s advanced performance systems are wrapped in an all-new seductive skin, giving the vehicle a kinetic feeling with emotional surface expression, sweeping character lines and tight panel gap lines.
“Compared with its predecessor, the G37 Coupe is longer, lower and wider – indicative of the power and technology of the vehicle,” said Igo.
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-xenon headlights with integrated fog lamps. As with the new G35 Sedan, Infiniti developed a specialized production process for headlight installation to impart tight build tolerances and an exacting fit of the complex front fascia. The aluminum hood is secured by dual latches located at the two front corners to ensure an excellent fit.
The strong side character line and side sills integrate with the large wheel wells and the 18- or 19-inch performance-oriented wheel and tire packages to transmit an added sense of power and vibrancy.
The rear of the G Coupe features broad rear fenders, flowing into the large LED taillights – an Infiniti trademark, refined rear bumper, integrated RearView Monitor camera (when equipped), rear underbody air diffusers and large dual exhaust outlets with chrome finishers. An available rear spoiler gives the G37 Coupe zero rear lift, matching the standard zero-lift front aerodynamics.
The G37 Coupe Sport 6MT models and G37 Journey 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 colors, including four new colors – Blue Slate, Platinum Graphite, Vibrant Red and Amethyst Graphite – are offered.
Sophisticated, Luxurious Interior
The 2008 G37 Coupe interior design 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 center console with a leather and aluminum-clad shifter. Special aluminum-alloy interior trim, inspired by elegant, handmade Japanese Washi paper, is located across the instrument panel, on the center console and on the door panels. Genuine African Rosewood trim is also available.
The instrument panel features Infiniti electroluminescent instrumentation with white-and-violet illumination and integrated multi-function information drive computer (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) display.
Drivers grip a double hand-stitched leather-covered steering wheel, designed for maximum comfort and usability with wheel-mounted audio and cruise controls. Available genuine magnesium paddle shifters for the 5-speed automatic transmission fall readily to hand and add control (G37 Coupe Journey with Sport Package only).

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.
Three Well-Equipped Models
