Organizers of the upcoming New York Auto Show have revealed that Infiniti’s long awaited replacement for the G35 Coupe will be unveiled at the show, carrying the new title ‘G37.’ The new name hints at the coupe’s expected powerplant, a 3.7L version of the venerable VQ series of engines. This engine is also said to be a less powerful version of the same unit that will power the next GT-R, although there are rumors of a new turbo model from Infiniti that will be slotted above the new G37.

Initial speculation puts the standard output of the 3.7L engine at about 325 to 330hp, just enough to eclipse the potent twin-turbo 3.0L straight-six from BMW. However, the biggest news centers around a possible ultra high-end model based on the same AWD drivetrain of the next GT-R.

This teaser image of the new car’s headlight shows that developers have stuck with the design as shown in a previous concept rendering. Infiniti will also be unveiling a crossover concept in New York, labelled the ‘Infiniti EX’ that will feature a traditional SUV body with coupe-like styling.

Infiniti’s new G37 Coupe breaks cover

Image


One of the star attractions planned for the upcoming New York Auto Show, Infiniti’s new G37 Coupe has been revealed ahead of its official embargo date. Aimed squarely at BMW’s popular 3-series coupe, the new Infiniti comes packed with a stroked version of Nissan’s multi-award winning VQ engine and now displaces 3.7L. The powerplant comes with Nissan’s all new Variable Valve Event and Lift technology, which provides the engine with a flatter torque curve and improved power delivery right across the rev-range.

Final output is 330hp and 270lb-ft, while the engine’s redline is set at 7,500rpm. Customers will be able to opt for a conventional six-speed manual gearbox or a five-speed self shifter, and limited-slip differential will be available with some models. The next-generation FM platform, which underpins the new G, is 36% stiffer than the previous G35 and has a wider track and a lower center of gravity. Other new additions include firm springs, larger sway bars and 18in wheels as standard, plus an all new four-wheel active steering system. The first cars should be in showrooms by the middle of the year.

Considering that the new G37 is packing so much performance, we’re shocked that its designers have dropped the sharp and edgy design of the previous model and have instead gone with a softer and more porky shape. The concept car was everything that the new G coupe should have been, but this car looks as though it has had a few too many milkshakes.

With the New York Auto Show only a couple weeks away, the embargos had to begin to break any day now. Road and Track started things off by releasing its May issue online early with a single of the new Infiniti G37 and a short driving impression. Edmunds Inside Line and Automobile smelled blood, and immediately opened the flood gates revealing everything they knew about Infiniti's new G Coupe. These news outlets were apparently invited to a sneak preview of the G37 at Nissan's test facility in Arizona last month, and while Infiniti likely set strict embargoes on publishing pictures and driving impressions of the new model, all it takes is one hole in the dam to start a deluge.

The full view of the G37 is stunning, with familiar cues from the G35 Sedan mingled with coupe-specific cues like a large front intake and fast profile. The headlights peel back into the front fenders giving the G37 an even more imposing presence than the current G35 coupe.

The already excellent 3.5L V6 from the G35 Sedan gets bored out by 4.6mm to reach 3.7 liters, and the compression is increased to 11.0:1 to create some outstanding power numbers. An estimated 330 hp and 270 lb-ft will move the 3,682 lb coupe, and the drive should be much improved with 36-percent stiffer underpinnings than the G35 coupe. Stopping power is also quite impressive, with 14-inch front and 13.8-inch rear rotors.

Infiniti showed the world it was no pushover in the entry luxury market with its first-generation G35 coupe, and we think the great looks and impressive power numbers of the all-new G37 may put Infinity at the front of the pack. Of course, the BMW 335i coupe leads the pack at the moment while weighing less and putting up bigger torque numbers with its twin-turbo inline-six, so we'll reserve judgment on whether or not the G37 wins by a nose until we've had the chance to drive it.

I know what you mean. Seeing the press release pics makes me think that this car will very easily stand out in traffic, while the actual photos make it look like it will blend in. I don't know, seeing those actual photos makes me like the current G35 coupe better. I guess I'll have to wait to see one in person.

Same here. The concept was badass looking. But unfortunatley as with all concepts. They always hipe up the looks of a vehicle and then the production version comes out and they look nothing a like. Take the 4g for instance. The concept was pretty neat looking and then we seen the production version.::ghey3:

It happens on lap 4. That's when the difference between Infiniti's 2008 G37 Coupe and BMW's 2007 335i Coupe crystallizes.

All at once the BMW coupe that we've considered the leader in its class finally decides it's had enough. With its oil temperature pinned at 300 degrees F and its coolant temperature climbing rapidly, the turbocharged Bavarian wonder engages its limp-home mode and we crawl pathetically back to the pits.

This all-too-dramatic demonstration of Japanese-versus-German engineering occurred at Nissan's Arizona Test Center, where Infiniti invited a select group of journalists to drive the 2008 Infiniti G37 Coupe back-to-back with Germany's best. The limp-home part, well, that wasn't part of the plan.

In fairness, both cars had experienced a relentless pounding by journalists with a profound absence of mechanical sympathy before the BMW finally succumbed to the desert heat. But the flogging had been similarly abusive to both cars, and the Infiniti G37 never showed any signs of weakness.

Major hardware changes
The 2008 Infiniti G37 Coupe is a fully updated version of the G35 coupe that put Infiniti on the map as a serious player in the market for premium sporting coupes. There's a new engine, new front suspension, updated styling both inside and out, and slightly altered dimensions.

The real news is the power plant, which received an increase in displacement to 3.7 liters thanks to a 4.6mm increase in stroke. Nissan's Variable Valve Event and Lift (VVEL) now alters valve timing and lift on the intake valves. Compression is increased from 10.6:1 to 11.0:1. These tweaks combine to increase output to a projected 330 horsepower and 270 pound-feet of torque. That's 30 hp more and 30 lb-ft less torque than BMW's 335i coupe. It represents an improvement of 24 hp and 2 lb-ft over the current G35 coupe's 3.5-liter V6.

Transmission options include a five-speed automatic, which is shared with the G35 sedan but includes a new calibration and modified torque converter characteristics. It also comes with shift paddles behind the steering wheel. Alternatively, there's a six-speed manual that is modified from the sedan to reduce vibration. Its clutch is also refined for smoother engagement. The test car we drove, however, featured the G model's five-speed automatic transmission.

The basis for the G37 is Nissan's revised FM (Front Midship) platform, which now boasts a 36-percent increase in rigidity over the G35 coupe. The front double-wishbone suspension now has a single, lower ball joint instead of the previous double ball-joint arrangement in order to reduce steering kickback. Rear suspension remains a multilink setup.

When the G37 is equipped with a sport package (as was our test car), it will feature the largest-diameter brake rotors in the segment. Fourteen-inch rotors are stopped by four-piston (two per side) front calipers. The rear setup will include fractionally smaller 13.8-inch rotors and conventional single-action two-piston calipers. In dynamic bench tests, the larger front rotors helped reduce brake temperatures by 100 F compared to the G35's sport-package brakes, which should translate directly to better fade resistance.

Four-wheel active steering (4WAS) steers the rear wheels up to 1 degree based on input from an array of sensors, and it will be available on coupes with the Premium Package. Adding in small amounts of rear steering effectively changes the overall steering ratio between 12:1 and 20:1. Rear steering is currently a $1,500 option on the 2007 Infiniti G35 Sedan, so we expect a similar price structure for the coupe.

New styling inside and out
The coupe's proportions remain the same, but there are significant detail tweaks that differentiate the newer, more muscular G. The grille now features Infiniti's signature double arch, the headlights and taillights are L-shaped and the rear deck incorporates an integral spoiler. There's also a distinct character line running the length of both sides of the hood.

Dimensionally the G coupe remains low and wide. Overall length is up about one inch while width and height change only 0.2 and 0.1 inch, respectively. The wheelbase is still 112.2 inches — considerably longer than both the BMW 335i and Lexus IS 350 sedan.

Anyone comfortable with the current G35 will feel right at home in the G37. Most of the hardware looks to have been lifted directly from the 2007 G35 sedan, including the seats, shift lever and steering wheel. The basic layout is the same as well, with a rounded door panel melding into the dash. Aluminum trim is plentiful — from the doors to the pedals with the Sport Package. And there's the Infiniti-signature oval analog clock built into the dash.

The instrument panel still moves up and down as the steering wheel's tilt is adjusted, but the magnesium shift paddles (right for upshifts, left for downshifts) do not turn with the wheel. The steering wheel on the Sport Package car we drove included audio, cruise control and Bluetooth buttons and had a satisfyingly fat leather-wrapped rim.

The sport seats still use an asymmetrical design with a small bolster in the middle of the driver seat and adjustable thigh extensions. The seat adjustment controls have moved from the side of the center console to more conventional placement on the outside of the seat bottom cushion.

Giddyup
From the first corner driven in anger, it's easy to sense the G37's focus. There's firmer damping and better body control than in the BMW 335i. More impressive is the steering, which offers a perfect compromise of surface feel, steering effort and feedback. This makes the G37 more intuitive and better behaved at the cornering limit than the BMW — and the car we drove hadn't even been fitted with the optional four-wheel steering.

The engine, despite its longer stroke, retains the 7,500-rpm redline of the G35 sedan and makes genuinely usable power at high rpm. In tight corners the G's viscous limited-slip differential puts power down consistently through 245/40ZR19 rear rubber. Infiniti staggers the tires so the front gets smaller 225/40ZR19 tires. Both the 19-inch wheels and limited-slip differential are exclusive to the Sport Package.

It's clear when driving hard that Nissan is keenly aware its competition has upped the bar. The improvements to the G37 are shrewdly focused in areas which help the G compare favorably in exactly the conditions we were given to test the cars — on a racetrack. With the Sport Package comes stiffer springs, more aggressive dampers and larger antiroll bars. We'll withhold judgment about the G's ability to adapt to real-world driving as brilliantly as BMW's 3 Series until we're able to drive them both on the street.

One area in which we know the G falls short is the shift lever for the automatic transmission, which must be toggled forward for upshifts and backward for downshifts — the opposite of BMW practice. We've always liked pulling back on the lever to trigger the next higher gear as acceleration drives us into the seat, as if we were shifting from 3rd to 4th gear. Pushing forward on the lever to downshift under braking is similarly intuitive.

Of course, if you use the shift paddles, none of this matters. Downshifts are executed with a perfect rpm match — a rare and impressive achievement in a transmission with a torque converter.

The question remains whether the G37 Sport will match the acceleration of the BMW 335i, which hits 60 mph in only 4.8 seconds and trounces the quarter-mile in 13.3 seconds at almost 106 mph. Our seat-of-the-pants assessment says that the G37 isn't quite up to that task, due mostly to its torque deficit, fewer gears (the Bimmer has a six-speed automatic) and heavier estimated weight (3,682 pounds vs. 3,571 pounds).

But anytime the going gets twisty and you're driving in the upper reaches of the power band, the G will leave the 3 Series in its wake with better top-end punch and a more performance-focused chassis.

Get yours
G37 coupes will hit dealers on August 21 of this year. Infiniti PR folks were characteristically tight-lipped about pricing, which won't be announced until just before the on-sale date.

If Infiniti follows tradition, however, it will undercut its German competition in price while offering similar or better performance. Currently, that means a G37 sport coupe with the five-speed automatic transmission will have to tally less than $44,000 — an easy task considering the current car with these options rings up a $35,750 tab.

More importantly, it probably won't ever limp home.

This really makes me curious how the '08 Z will be treated. The '07s got a minimal HP bump compared to this, (306 vs 330) and similar weight. It seems odd to me that Nissan would make the '07 Z for all practical purposes useless, because of what is probably going to come for 2008. I'm guessing the Z will be the 370Z and use this engine and make 340 or 345HP. :lol:

Nissan seems to do this in-between screwing around with the HP, a lot. They did it with the 00-01 Maxima, which was at 222HP with a 3.0l then all of a sudden in '02 they brought in the VQ with the 3.5l and gave it 255HP, and so on. It just doesn't make much sense.

I feel bad for anyone getting a '07 Z right now, unless they are getting it for cheap.

At a Glance: 2008 Infiniti G37 Coupe

The all-new 2008 Infiniti G37 Coupe, which makes its world debut at the 2007 New York International Auto Show, combines the exhilarating performance, stunning styling and modern, sporty interior of the original Infiniti G Coupe, accelerating each to new levels. The new, second generation G Coupe is set to arrive at Infiniti retailers nationwide in August 2007.

Leading the enhancements to the G37 Coupe is the first-ever application of the new 3.7-liter V6 engine with VVEL (for Variable Valve Event and Lift). Estimated at 330 horsepower and 270 lb-ft of torque, the VQ37VHR contains approximately 35 percent unique parts content from the new VQ35HR engine introduced in the 2007 G35 Sedan last year.

Along with utilizing a larger displacement than the previous 3.5-liter powerplant, the VVEL system combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side, helping to improve not only performance and response but also emissions and fuel efficiency. Overall vehicle fuel economy improvements are estimated to be nearly one mpg better than the G35 Sedan and nearly two mpg better than the previous generation G35 Coupe (actual EPA ratings will be announced at a later date). The engine is backed by a choice of an upgraded electronically controlled 5-speed automatic transmission with available paddle shifters or a significantly revised and more refined 6-speed manual transmission.

The G37 Coupe’s enhanced platform and chassis also includes an available advanced 4-Wheel Active Steer system (4WAS), which helps improve vehicle handling performance by adjusting both the front steering gear ratios and the rear suspension geometry according to steering input and vehicle speed. Braking and handling is targeted to be among the best in the luxury sport coupe class.

All of these advanced performance systems are wrapped in an all-new seductive skin. The G37 Coupe exterior design features flowing front fender curves, a wave-style hood, smooth front fascia with Infiniti’s signature double-arch grille and L-shaped headlights. The side character line and side sills, as well as large wheel and tire packages transmit an added sense of power and vibrancy.

Inside, Infiniti-levels of craftsmanship are apparent throughout the all-new interior design, including the use of unique materials and finishes with traditional Japanese design cues. The new G Coupe also includes an extensive list of available technological features – a touch screen navigation system with XM® NavTraffic™ real-time traffic function, RearView Monitor and an available 11-speaker Infiniti "Studio on Wheels"™ by Bose® audio system with 24-bit Burr Brown DAC, 3-way door speaker arrays with 10-inch woofers and a 9.3-gigabyte Music Box hard drive.
