2011 Infiniti G37 Sedan Journey review: 2011 Infiniti G37 Sedan Journey

Compared with its sleeker sister, the Coupe, the G37 Sedan looks a bit frumpy from certain angles. Then again, in the shadow of a supermodel, I think we'd all fall a little short. Compared with other midsize premium sedans, the G37 Sedan is arguably one of the best-looking vehicles in its class and definitely one of the best-looking vehicles in the entirety of the Nissan/Infiniti lineup.

The Good

The <b>2011 Infiniti G37 Sedan Journey</b> checks all of the right cabin tech option boxes. The hard-drive-based navigation system features traffic, weather, and voice commands. Hands-free calling and rearview camera are standard. The Bose audio system provides well-balanced sound.

The Bad

Observed fuel economy was unimpressive. Infiniti's packaging and pricing structure may lock some users into spec'ing unwanted options.

The Bottom Line

The 2011 Infiniti G37 Sedan Journey earns its price tag with great tech and performance, but its ride may be too sporty and harsh for its single-option automatic transmission and for its target audience.

We spent some time with the 2011 Infiniti G37 Sedan Journey to see if that beauty goes deeper than the skin.

Performance
Under the sculpted hood is Nissan's workhorse 328-horsepower V-6 engine. A version of this engine (internally known as the VQ series) also finds its way under the hood of Nissan's Maxima, Murano, Quest, and 370Z and nearly every vehicle in Infiniti's lineup. This implementation displaces 3.7 liters and twists its crankshaft to the tune of 269 pound-feet of torque. Power is directed to the rear axle via a seven-speed automatic transmission with standard, sport, and manual modes.

The VQ-series engine beneath the hood of the G37 Sedan displaces 3.7 liters and outputs 328 horsepower.

Tapping the admittedly well-made optional magnesium paddle shifters felt rewarding to the fingertips. However, the manual shift mode itself left much to be desired and was actually rather annoying. The play-by-play went something like this:

As I approach a corner, I grab the paddle shifter for a downshift in preparation for the turn. Instead of immediately changing gear, the G37 hesitates for a moment while it decides what needs to happen. By now, I've slowed to the appropriate cornering speed and am easing off the brakes and beginning to turn the wheel. The gearbox decides that now is the perfect time for shifting and momentarily pops out of the current gear to match the revs for the downshift, canceling all engine braking and causing the car to lurch and toss its weight to the rear axle. As the sedan and I approach the apex, the gearbox pops back into the now lower gear and higher engine speed, suddenly reapplying an increased level of engine braking and causing the chassis to lurch forward and throw its weight back over the front axle, scaring the absolute crap out of me as I (and the traction control system) wrestle to keep the rear end of the sedan behind the front.

Drawing enjoyment out of the G37 Sedan turned out to be an exercise in the management of expectations. The standard and sport transmission modes are perfectly adequate for tooling around town or tackling a moderately challenging B-road, respectively. The latter mode is quite nice, allowing the engine's revs to rise slightly higher before shifting for increased power and even downshifts as the driver brakes in preparation for a turn. Leaving the G37 in this sport transmission mode and driving the sedan in a manner that's more Lexus GS than BMW 5-series yielded better results.

After a week of mixed casual and spirited driving, the trip computer reported 20.8 mpg. That's at the low end of the EPA estimated range of 19 mpg city and 27 mpg highway.

Scaling back on the sporty driving wouldn't be that big a deal if our G37 weren't loaded up with $2,520 worth of "sport" options. The $2,150 Sport Package upgrades the wheels to 18-inch aluminum rollers shod in summer performance tires, replaces the standard suspension with sport-tuned components, adds a viscous limited-slip differential, and upgrades the brakes to four-pot and two-pot calipers for the front and rear disc brakes, respectively. The package also adds the aforementioned magnesium paddle shifters as well as aluminum pedals, and swaps in a sportier body kit and sport seats. Those buckets are deeply bolstered, but with 12 directions of power adjustment for the driver's seat and 8 for the front passenger, they're more of a comfort addition than a true performance upgrade. Even the headlights become "Sport headlights," although we're not really sure what's so sporty about them, and a shiny red letter S gets affixed to the end of the "G37" badge on the rear decklid. Our sedan was also equipped with a $370 set of R-Spec high-friction brake pads.

The Car Tech staff was split over whether this Sport package was worth the dough. I think it's a bargain, but Editor-at-Large Brian Cooley seemed to think that the suspension was too stiff, too boy-racer for the upright G Sedan. (Check out the video at the top of this review to hear him explain this in his own words.) I welcomed the G's firm sport suspension setup and the levels of grip that it afforded. Admittedly, my idea of a "firm ride" may be slightly higher than many, but I liked that the G37's chassis communicated the bumps and imperfections of the road without crashing over them. Then again, the last car I drove before being tossed the keys to the G37 Journey was a low-spec 2012 Nissan Altima with a suspension made of what I believe to be mashed potatoes, so perhaps I was just eager for a bit of fun.

What you end up with upon adding that Sport package to the G37 Journey is a sedan that accelerates, stops, and handles better than its gearbox can keep up with. Fortunately, Infiniti offers the G37 Sport 6MT, which rolls in all of the options of the Sport Package, but drops the seven-speed automatic gearbox for a six-speed manual transmission with a proper clutch pedal. If you're the sort of driver who cares about anything listed in the Sport package's list of options or wants to explore the limits of the G37 Sedan's capability, the Sport 6MT is the trim level for you. Otherwise, skip the Sport package altogether and be prepared to take it easy.

Comfort and safety tech
As it turns out, the G Sedan isn't a bad place to take it easy. With standard leather trim, automatic temperature control, and a spacious cabin that envelops up to five adults (four comfortably) with enough sound deadening to permit low-volume music and conversation without shouting in the middle of a rainstorm, I was more than happy to adjust the driver's seat to a more relaxed position and cruise. The wide tires and stiff suspension transmit a noticeable amount of road noise into the cabin at highway speeds, but not an unforgivable amount. Again, if a quiet ride is what you're after, you'll want to test-drive a G37 Journey sans Sport package.

Cabin comfort options start with the standard 7-inch information display mounted at the top of the center stack. This gives drivers access to the climate control systems, audio controls for the standard USB/iPod connection, XM Satellite Radio tuner, single-slot CD player, and Bluetooth hands-free phone system. This screen is also where the drive can display the view from the rearview camera, which is also standard.

Stepping up to the $2,150 Premium package adds a beeping sonar proximity detector to the rear camera system, power adjustment to the steering wheel, driver memory settings for the standard power seats, a power moonroof, and a 2.0GB Music Box audio storage system that curiously only lists 800MB of available space. We're not sure what happened to the other gigabyte of free space, but that only leaves room for about 250 songs. Most importantly, the Premium trim level replaces the standard six-speaker audio system with the rather loftily named Infiniti Studio on Wheels premium audio system by Bose. This 10-speaker rig performed, to my ear, about like any other Bose-branded audio system that we've tested. It would seem that Bose has tuned much of the boominess out of its car audio systems, as the G Sedan's setup produced a very balanced sound. However, strong bass is just two ticks of the bass level away and sound remains essentially distortion-free at most volumes as long as you don't get too far from center with the EQ's settings.

Our vehicle was also equipped with a $600 Interior Accents package that adds high-gloss Maple trim to the cabin.

Infiniti's hard-drive-based navigation system features easy-to-read maps and snappy performance.

Checking the box next to the $1,850 Navigation package unlocks the next level of tech. The 7-inch information display becomes a touch screen and is now backed up by a HDD-based navigation system, a DVD player, and Infiniti's voice recognition system. In the presence of the navigation system the standard XM Satellite Radio receiver begins to download XM NavTraffic and XM NavWeather data and advisories. The navigation system's larger 9.3GB hard drive also features more space for audio storage. Maps show 3D buildings and landmarks and are attractive and easy to read. However, Infiniti's system does look a bit Fisher-Price when compared with the advanced graphics of BMW's and Audi's navigation systems.

Because of the way Infiniti has tiered its packaging, the options must be added in a specific order. So if you're not interested in the Sport package, you'll want to stop here, because that's the next package. Unfortunately, skipping the Sport package means that you'll be locked out of selecting the Technology package. Even odder, selecting the Sport package automatically specs the Tech package, which causes me to question why they're even separate packages to begin with.

Our tester, at any rate, was equipped with both the $2,150 Sport and the $1,200 Technology packages. The latter option adds automatic windshield wipers, an upgraded climate control system, and Intelligent Cruise Control (ICC), which uses forward-facing radar to automatically maintain a set distance between the front bumper and the vehicle ahead. Interestingly, Infiniti used a similar active cruise control system on the FX50S that we tested a few years ago that would slow the vehicle all the way down to stop-and-go speeds if necessary. The ICC system in the newer G Sedan deactivates below about 35 mph. Additionally, the ICC can't be set while the automatic windshield wipers are active. This is presumably for safety. However, if you set the ICC first, activating the wipers will not then disable the cruise control.

The Intelligent Cruise Control system uses forward-facing radar to maintain a safe following distance between you and the vehicle ahead.

Speaking of safety, the ICC's forward-facing sensor also acts as a crash-detection sensor that can trigger pretensioning of the seatbelts and preloading of the braking system in the event of an impending collision. As much of our testing was conducted in the rain, we did not put this system to the test.

In sum
All in all, with an $875 destination charge, our 2011 G37 Sedan Journey came to an as-tested price of $44,245. That's not a bad price relative to a similarly equipped BMW 335i sedan. The Bimmer would yield a more satisfying driving experience than the Infiniti, but at almost $10,000 more, it had better!

However, it can be difficult to optimize the G Journey Sedan to your needs because of the way Infiniti sets up its packaging. We'd recommend that the driver wanting to maximize comfort and safety tech stop checking option boxes at the Premium and Navigation packages and roll off of the lot with a $41,695 car. Performance drivers are probably looking at the G Coupe, but those who need four doors will want to test-drive the G37 Sport 6MT Sedan, which is an all-or-nothing affair that combines the options of the Premium, Navigation, and Sport packages with the addition of a six-speed manual gearbox for $41,495. Neither scenario features the option to spec the Technology package and its ICC system, but I'm not so sure that's a deal breaker for many.
