2008 Infiniti G35 Luxury Car Review & Performance

When the Infiniti G35 was redesigned for 2007, it was an evolutionary styling change from the first-generation model (2003-06).

The grille has crossbars that flatten at their extremes, an expression the car's stylists liken to sword blades. Compound, multi-element, L-shaped headlight housings wrap around the fenders. A one-piece fascia with three large air intakes across its lower reaches embraces the front end. The tops of the front fenders flow over into the hood, emphasizing the G35's width and enhancing its planted look.

The side view presents a relatively long hood, steeply raked windshield, fast backlight and brief rear deck, giving the G35 more the look of a sporty coupe than the four-door sedan it is. Recessed door handles sit almost flush with the sheetmetal. Tires snugly fill slightly flared, circular wheelwells. A rocker panel accented by a deep indent along the bottom of the doors pulls the sides of the G35 closer to the road.

Large, LED taillights repeat the L-shape of the headlights, crossing over from the fenders into the trunk lid. The trunk lid dips several inches into the rear fascia, compensating somewhat for the restricted opening imposed by the short rear deck. Proper dual exhaust tips exit beneath each side of the fully integrated rear bumper.

The interior is lively and friendly without being fussy or overly busy. There's luxury aplenty, but tempered by a focus on function, on connecting the driver to the car while at the same time providing passengers a pleasant and comfortable environment and entertaining diversions.

Audio and climate controls are conveniently located out in the open, on the face of the center stack, audio above and climate below, as they should be. A large, multi-function, knob-like control in the panel beneath the screen at the top center of the dash controls some functions, but its duties and operational planes are limited and minimally distracting.

The navigation system is controlled by this knob. Voice commands can be used for many operations. The navigation system offers a Birds Eye, which gives a perception of distance, incorporating a horizon and, depending on the available mapping data, three-dimensional building footprints for the local surroundings. It's neat to look at, though the regular overhead view the system uses works better for us. The XM Satellite Radio system provides real-time traffic updates, where available.

The cabin is trimmed with aluminum alloy, finished in what the designers call Washi, a texture intended to recall traditional Japanese rice paper. The optional African Rosewood trim looks as authentic as it is. Violet hues dress up white-on-black gauges.

The seats are comfortable, with thigh support a bit above average; even so, we wish the manual thigh-support extensions on the Sport Package seats were standard or at least available across the line. The adjustable torso and thigh bolsters on the Sport seats do what they're supposed to but favor slender bodies. The gas pedal and the rest for the driver's left foot are on different planes, leaving the knees at different angles, which is not the most comfortable position for long drives or for spirited motoring on winding roads.

The Bose Studio On Wheels delivers a sound that's richer, fuller, more intricate and crisper than any system we can recall in cars costing thousands, sometimes tens of thousands of dollars more than the G35. Although we're not prepared to go as far as Infiniti and compare it with a custom-configured, high-tech, in-home system, we stepped directly from a G35 sedan into a $100,000-plus European sports coupe with that marque's top-level sound system and could not distinguish a significant difference between the two. The G35's system's digital processing and eight-channel equalizer no doubt play a huge part, but our ears told us that almost as important is the Bose-designed speaker array. Infiniti claims, for instance, that the G35 is the first in the industry with a three-way, 10-inch subwoofer in each front door; the remaining eight speakers are traditionally located, with another 10-inch woofer in the rear parcel shelf, a 6.5-inch, full-range speaker in each rear door, three mid-range speakers across the front of the cabin, and a one-inch tweeter in each A-pillar.

Interior roominess is competitive for the class. Wide rear door openings leave room aplenty for legs, knees and feet when getting in and out.

Trunk space is competitive for the class.

Cubby storage includes a respectable glove box. The front center console provides as many as three cup holders, one inside the covered storage bin, and a can holder is molded into the hard-plastic map pocket in each door. Two cup holders pop out of the front of the fold-down, rear seat center armrest; a unique compartment masked by a Velcro-type flap on the right side is the surprise. The back side of each front seatback has a magazine pouch.

The Infiniti G35 delivers responsive performance. Stand on the gas and it pulls right up to its maximum rpm. It willingly and heartily revs to levels normally associated with smaller, less complex engines.

Fuel economy is an EPA-estimated City/Highway 17/24 mpg for the G35 automatic, 17/25 mpg with the manual, and 17/23 mpg for the G35x. The 2008 Lexus IS 350 betters the G35 by 1 mpg.

The manual and automatic transmissions ably handle the engine's power and power curve. The automatic does its job rather casually at part throttle. Holding the right foot unwaveringly hard to the floor produced sharper, more solid shifts at the engine's redline. The automatic changes gears the quickest and, interestingly, the smoothest with either the shift lever or the column-mounted paddles and under full throttle; it's like a power shift but without the clutch. Credit this to the engine's electronics, which feather the throttle through the instantaneous shift. The same electronics deliver smooth downshifts, too, whether in full auto mode or manual override, by blipping the throttle to match engine rpm to transmission speed in the lower gear; think double clutching a pure manual gearbox. The all-wheel-drive G35x has a snow mode that also electronically tempers throttle response.

The six-speed manual shift pattern was tight and gear selection was precise, requiring little effort. Clutch operation is heavier than we would expect even on a sports sedan. This makes for sometimes rocky clutch engagement, especially at low speeds and light throttle.

Ride and handling are consistent across the line.

The notable and commendable exception of this is the Sport models with four-wheel steer. Besides actively adjusting the rear wheel toe by up to a degree depending on vehicle speed and steering angle, the four-wheel steering brings with it a sportier shock and spring setup and road speed-sensitive, variable ratio power steering. For hustling down winding roads, this suspension and 4WS is the preferred combination, and it's not all that far out of its element cruising the Interstate. It's solid and taut and manages the G35's mass very well without exacting a price in stiffness. It's firm, yes, and will transmit pavement heaves more dramatically into the passenger compartment. But over anything less than chunking blacktop or weathered concrete, it gives up very little against the standard suspension, which leans a bit more toward supple. Not that the base suspension is floaty by any means, far from it, actually. But as demonstrated over several fairly hot laps on a racetrack, it's not as planted and controlled as the 4WS Sport.

On freeways, the G35 cruises comfortably and quietly. Gone is the irritating drone that often plagued rear seat passengers in earlier G35 sedans. There's little wind noise even at extra-legal speeds. There's more road noise from the optional tire packages than from the standard treads, but the added grip and, frankly, sharper looking 18-inch wheels are worth it.

The 2008 Infiniti G35 is offered in two models: G35 and the all-wheel-drive G35x. Both are powered by the same 3.5-liter V6 engine making 306 horsepower. A five-speed automatic is the standard transmission; a six-speed manual is available as part of a Sport Package. Option packages make it possible to tailor the G35's personality to your personal preferences.

The G35 ($31,600) comes standard with leather-appointed upholstery, an eight-way power driver's seat, and a four-way power front passenger seat; automatic climate control; power windows, outside mirrors and central locking; AM/FM/CD/MP3/XM stereo with 3-pin auxiliary audio input; multi-function trip computer; seven-inch color center-dash LCD monitor; tilt and telescoping steering wheel; analog gauge cluster that tilts with the steering column; aluminum interior trim; RFID-based, keyless ignition; HID bi-xenon headlamps; fog lamps; fold-down rear center armrest with lockable trunk pass-through; and aluminum-alloy wheels with P225/55VR17 all-season tires. The Journey Package ($450) adds dual-zone automatic climate control with rear air conditioning vents, eight-way power for the front passenger seat, an in-dash six-CD changer, and automatic on/off headlights.

The G35x ($34,100) adds the content of the Journey Package, heated front seats, and all-wheel drive. Options are similar to those for the base model.

The Premium Package ($2,500) adds a power tilt-and-slide glass sunroof, heated front seats with additional power adjustments, an upgraded memory system for seat and mirror preferences, power tilt-and-telescope steering wheel, a 10-speaker Bose Studio on Wheels system with Burr Brown Digital Audio Converters and iPod interface, Bluetooth hands-free phone system, and other convenience items.

The Sport Package ($1,650) includes bigger brakes, 18-inch aluminum wheels with W-rated summer performance tires, a limited-slip rear differential, magnesium paddle shifters mounted on the steering wheel, front sport seats, and unique front fascia and side sills. The Sport Package MT ($1,700) includes the same equipment, but replaces the five-speed automatic transmission with a six-speed manual, and replaces the automatic's pedal-operated handbrake with a pull-up lever. Buying the Sport Package MT is the only way to get a manual transmission in a G35. New for 2008 is a Sport Package AT ($1,100) for the G35x, which comprises similar equipment but skips the larger brakes and mounts 18-inch all-season tires.

The GPS Navigation Package ($2,150) includes such advanced features as a 9.3GB Music Box hard disc drive (instead of the in-dash, 6CD changer) MP3-capable compact flash media slot; lane guidance, which preps a driver for a left or right exit ramp from a freeway; and voice recognition for climate control, audio and navigation functions. This package is available only with the Journey and Premium Packages. The Technology Package ($1,100) adds Intelligent Cruise Control, adaptive front lighting, and Preview Braking. It requires the Navigation Package.

Other options include a tilt-and-slide glass sunroof ($1,000); an 18-inch Performance Tire and Wheel Package ($400); an African Rosewood interior trim package ($450); and active four-wheel steering ($1,500), which includes unique suspension tuning, but is not available with AWD. Very few options on the G35 are truly stand-alone; almost all require the Journey Package, and some options exclude others.

Safety features that come standard on all models include dual-stage frontal airbags with occupant detection and seatbelt pretensioners and load limiters; front seat-mounted, side-impact airbags (for torso protection); roof-mounted, front and rear side-impact air curtains (for head protection); active front-seat head restraints; rear seat child safety seat anchors (LATCH); antilock brakes with electronic brake-force distribution and brake assist; electronic stability control; and tire pressure monitoring.
