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.

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.

Also available on the 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.

New for 2009 is the G37x Coupe AWD with Infiniti’s 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 center 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 (BA). 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.

Split 5-spoke 18-inch aluminum-alloy wheels with P225/50VR18 all-season tires are standard on G37 Coupe. A 10-spoke 19-inch wheel and tire package, with lightweight cast aluminum wheels and high performance tires, is also available. A Tire Pressure Monitoring System (TPMS) is standard on all 2009 G37 Coupes.

Enhancing the already high level of dynamic performance of the G37 Coupe 6MT and G37 Coupe Journey with Sport Package are a unique sport suspension, a Viscous Limited Slip Differential (VLSD) and 19×8.5-inch front wheels with P225/45WR19 front tires and 19×9.0-inch rear wheels with P245/40WR19 rear tires.
