At some point, the realization that the Japanese do sport sedans as well or better than the Germans is going to begin to really sink in.  That is, if it hasn’t already.  Exhibit A is the 2009 Infiniti G37 Sedan, which seems about as far from its roots in the G20 as Tokyo is from Munich.

The Drivetrain

Top priority with a top sports sedan is the ability to still provide functional daily transport if required.  In our book, rear-wheel or all-wheel drive is also a requirement and both are available with the G37.  Particularly with the latter, the Audi and its venerable “Quattro” remain the Lords of that domain.  But Infiniti has their own high-tech drivetrain marvel in the form of VVEL (variable valve event and lift) technology that is coupled to either a seven-speed automatic or six-speed manual transmission.  The automatic can be controlled via shift paddles if the sport package is added.  Power is derived from an economical 3.7-liter V6, 328 horsepower engine that still achieves 26 mpg on the highway with high-octane fuel.

To directly compete against the best European brands, Infiniti/Nissan has pulled together a special team of specialists that have addressed all previous shortcomings and ensured that aerodynamic efficiency, handling and braking performance are all on point.  The numbers seem to indicate success.  0-60 mph comes in less than 5.5 seconds and handling is aided by improved weight balance front to rear and an abundance of lightweigh aluminum components.  Four-Wheel Active Steer (4WAS) is available as part of the Infiniti G37 Sport model and improves handling performance by varying the front steering ratio and adjusting the geometry of the rear suspension according to steering input and vehicle speed.  The AWD version of the G37, known as the Infiniti G37x, uses Infiniti’s ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split).  That’s a lot of letters, but in short, the system uses an active torque distribution management system with an active clutch for smooth starts and greater grip on slippery surfaces without compromising the vehicle’s rear-wheel drive performance characteristics on dry roads.  All versions of Infiniti G37, whether rear or all-wheel drive come with Electronic Stability Program (ESP). Power-assisted four-wheel vented disc brakes have a four-channel, four-sensor Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). The power steering system is a vehicle-speed-sensing design, which provides optimum steering effort at both high and low vehicle speeds.

Depending on your expectations, the G37 is either merely solidly functional or appropriately upscale.  Quality is not shirked in either case with the usual leather, aluminum and electronic appointments.  The interior cabin itself is larger than average for this class because of an increase to the vehicle’s wheelbase.  The beneficiaries are the back seat passengers who will no doubt appreciate the extra leg room.  In the front, the center console bisects the two cockpit-like front seats.

Sport sedan style trends as of late are to attempt to replicate the spirit of a coupe, albeit with four doors.  The G37 definitely channels its inner coupe with a long hood and curving roof that culminates in a slightly ducktail-like trunk.  Typical Infiniti DNA can be found in the L-shaped headlamps and wraparound tail-lights are another Infiniti signature design.  Slightly bulging wheel arches effectively communicate a sporty image.

Standard Features and Options

As opposed to the frequent nickel and diming that automakers inflict on buyers for every extra,Infiniti provides a longer than average list of standard equipment.  That means every Infiniti G37 has the Infiniti I-Key with smart access as standard. As soon as the vehicle identifies a pre-programmed I-Key in the vicinity, the door can be opened and the car started without the key needing to leave a pocket or handbag.  Personal settings for the driver’s seat, steering wheel and exterior mirrors can be programmed into the key (on any car specified with leather seats) so that the key holder won’t have to reposition anything if the car has been driven by anyone else.  Also standard are a six-disc, seven speaker CD audio system, Bluetooth mobile phone connectivity, cruise control, power seats, auto-dimming rear view mirror, front and rear parking sensors, automatic lights and wipers, 18-inch alloy wheels, six airbags and integrated fog lamps.  The leather trimmed steering wheel has controls for the audio system, cruise control and telephone.  The G37 also has an adaptive front-light system (AFS) as standard.  Unique to Infiniti is the use of “Scratch Shield” paint.  A special highly elastic resin has been combined with a conventional clearcoat to increase the paint’s durability.  A car painted with “Scratch Shield” paint can exhibit up to five times fewer scratches that a conventional clearcoat when exposed to the same conditions.

The leather package, includes leather seats, heated in the front, power lumbar support in the driver’s seat and eight-way adjustment for the passenger seat in place of the standard four-way adjustment.  The Sport Model provides a different style of 18-inch alloy wheel, tyre pressure monitoring, a viscous limited slip differential and sports settings for the suspension, steering and brakes.  It also features Four-Wheel Active Steer (4WAS). By monitoring steering angle and vehicle speed data, the 4WAS controller calculates the difference between current performance and optimum target data which is pre-programmed into the system.  Also included in the sports package are sports front seats. The heated and leather covered seats have thigh extensions for greater support, while the driver’s also has power operated lumbar and lateral support. As with the leather package, the passenger seat is upgraded to 8-way power adjustment.  The multimedia package includes satellite navigation, a rear view camera and a Bose premium audio system.

Price

The Infiniti G37 starts in the $33,000 range, though the more spirited versions push the price into the lower 40 grand range.  Still, at any price the G37 is several thousand less than a comparable BMW.
