Review of the 2010 Infiniti G37 Sedan

  • Sport-focused, intelligently designed and attractively priced, the 2010 Infiniti G37 is an excellent choice for an entry-level luxury sport sedan, coupe or convertible.

  • Safety
  • Pros

    Muscular V6 engine, wide range of body styles, sharp handling, strong brakes, easy-to-use high-tech features, attractive price.

  • Cons

    Coupe's cramped rear seats, convertible's diminished performance, complicated and expensive options structure, engine gets a bit raucous at high rpm.

After almost 3 years

Vehicle: 2010 Infiniti G37 Sedan Journey 4dr Sedan (3.7L 6cyl 7A)

It's almost 3 years since we bought our G, and we have no regrets. Other than routine servicing, it's only been in for three TB's - one for transmission (it worked), navigation (another story), and the rear passenger window air leak (caused wind noise at speed - corrected). The initial enthusiasm for the navigation system waned as we regularly were directed to non-existent destinations (such as restaurants in the middle of established residential areas). This is a poor data issue that Infiniti refused to address. The fuel economy (mainly highway) has consistently amazed us - even at 75 mph we average 26-27.

Beyond the looks, the car

Vehicle: 2010 Infiniti G37 Sedan Journey 4dr Sedan (3.7L 6cyl 7A)

After a few Honda Accords, an Acura TL, and BMW 325i I was excited to take my 2010 G37 Journey with tech and navi packages home. But that is where I am most comfortable in the this car, at home. Trany is rough in auto or sport - dealer, after a few visits cannot identify the problem. Downshifts are unreliable and harsh. Interior noise is not what I would expect; wind, road, and tire noise is louder than it should. Paint quality is poor. Just passed 10k miles and examining the hood would make you think it has many more miles. I keep it washed weekly, waxed every 60 days, and you wouldn't know it.

Excellent overall. It balances handling, comfort and exceptional value. I looked at all the usual suspects. 3 series, C-Class, Acura, Lexus and found the G37 to represent the best of all these brands. 3.7liter is a rocket on wheels, precision handling when pushed and comfortable in city driving. Exceptional navigation system, very easy use with both voice command and touchscreen. Great driving position. I have about 4k miles and its been very reliable compared to my 2008 Audi A6. Service costs are very reasonable. Good long distance cruiser. Like BMW and Mercedes, G37s are built on independent rear wheel drive platform unlike Lexus ES and Acura TL.




Best of the four

Vehicle: 2010 Infiniti G37 Sedan Journey 4dr Sedan (3.7L 6cyl 7A)

This is our 4th Infiniti since 1997 (two I30s, G35 and now G37). It is by far the best of the four - I can't believe I'm getting the same fuel economy as the 2000 I30 with 227 HP and better than the G35 with 260 HP. Still new to the area, so the Nav system helps and is the best one seen to date. I love the fact that I have all my music on a USB stick and can use it with the system (no Ipod yet). Did I mention the heart rate when I step on the gas? Or corner, or stop fast? I love this car!

Very good, but not great

by on
Vehicle: 2010 Infiniti G37 Sedan Journey 4dr Sedan (3.7L 6cyl 7A)

This is a very good car with strong acceleration. The packages are well designed and standard equipment is good. My biggest gripe is with the 7-speed transmission which is jerky between gears 1-4 (apparently a known issue). At highway speeds it's a gem. The stock seats, while comfortable, are just not right for this car. I would seriously consider the sports package just for the unique seats and greater "snug" factor.

I traded in a 2009 Acura TL tech for the G37 and so far it has been a great choice. The TL is a very good car but it did not get me emotionally involved but was a pleasant car to drive. The TL tech is too complicated and has too much stuff and too many buttons. The G37 is truly remarkable and very fun and engaging to drive. It is nimble and very fast. I like the lines better and the interior is much better and more intuitive. I have the polished wood accents and just love it. Great car for the price and really exciting to drive and own!

What's New for 2010

For 2010, the Infiniti G37 sedan receives minor styling updates in the form of a new grille, headlights and bumpers. Inside, all G37s gain new gauges, metallic accents and, for those equipped with navigation, real-time traffic and weather as well as streaming Bluetooth audio. Mechanically, nothing has changed, though the previously available four-wheel active steering option has been discontinued. Finally, a new 20th Anniversary Edition debuts.

Introduction

In recent years, it's gotten even harder to choose an entry-level luxury car. Each automaker has been trying to outdo the others by offering even more powerful engines, new body styles and high-tech features. The end result is a batch of cars that might as well be equally good. Yet the 2010 Infiniti G37 still manages to stand out among this group thanks to its sharp styling and strong dynamic performance.

Certainly, the G37 is one of the more entertaining vehicles to drive in this segment thanks to its strong 328-horsepower V6 engine and agile handling. And visually it stands out in a crowd with its arcing bodywork. But the 2010 G37 does more than just go fast and look good; it also keeps its occupants comfortable and entertained throughout the journey thanks to a stylish cabin, the latest high-tech features and a suspension that's still supple enough to absorb the bumps and ruts of the daily grind.

Originally, Infiniti's G was available as just a coupe or a sedan. Last year, a new retractable-hardtop convertible debuted, giving G buyers a third, enticing option. The newest G offers the quiet comfort of a coupe when the top is up, and the exhilaration of a convertible when it's automatically stowed under the trunk lid. The downside is that the top and its associated mechanisms and reinforcements add a considerable amount of weight (the drop top weighs 450 pounds more than the coupe) and reduce luggage space to virtually nil when it's stowed.

There are a few other downsides as well, including the coupe's cramped rear seats and a tricky option pricing structure. And compared to the long-standing segment leader -- the BMW 3 Series -- the 2010 Infiniti G37 still isn't quite as communicative to the enthusiast in terms of steering feel and feedback. One might also consider the Audi A4/A5, Cadillac CTS and Mercedes-Benz C-Class, all of which have their own particular strengths. Yet even among this stellar group, Infiniti's G37 remains one of our top picks for its standout combination of performance, styling and comfort.

Body Styles, Trim Levels, and Options

The 2010 Infiniti G37 is offered as an entry-level luxury sport coupe, sedan or retractable-hardtop convertible in four trim levels -- base, Journey, G37x and Sport 6MT -- except for the convertible, which is offered only in base or Sport 6MT trim.

The base G37 comes standard with 17-inch alloy wheels (18s on the coupe), xenon headlights, keyless ignition and entry, automatic climate control, leather upholstery, full power accessories, a power driver seat, a tilt-and-telescoping steering wheel and a six-speaker audio system with a CD/MP3 player, satellite radio and an auxiliary audio jack. In keeping with modern trends, the G37 convertible has a retractable hardtop that stows beneath the trunk lid in less than 30 seconds.

The Journey trim level adds automatic headlights, dual-zone climate control, a six-CD changer and a power front passenger seat. Stepping up to the G37x all-wheel-drive model adds heated front seats and outside mirrors. The Sport 6MT trim level brings added performance features and the six-speed manual transmission. It comes standard with 18-inch wheels with high-performance tires (19-inch wheels on the coupe), sportier exterior and interior treatments, a limited-slip rear differential, upgraded brakes, a sport-tuned suspension and seats with added thigh and torso support.

There are no options available for the base G37. The numerous options for the other trim levels are typically only available via a range of packages. The Premium package includes a sunroof, rear park assist, a power tilt-and-telescoping steering wheel, driver memory settings, Bluetooth, an upgraded Bose audio system (of which the convertible gets a purpose-built version with headrest-mounted speakers), iPod connectivity and -- for the convertible only -- ventilated seats.

The Navigation package can be added to the Premium package and includes a hard-drive-based touchscreen navigation system (with streaming Bluetooth audio as well as real-time traffic and weather), voice-activated controls, a 9GB music server and a rearview camera. The Technology package, which is only available with the previous packages, includes adaptive cruise control, adaptive headlights and an upgraded climate control system. Other options include a Sport package (it adds most of the 6MT's equipment to the Journey or G37x), 19-inch wheels, a rear spoiler and interior wood trim.

The 20th G Anniversary Editions are based on the G Sedan Journey and AWD, G Coupe Journey and G Convertible. The Premium and Navigation packages are included. The sedan and coupe also get the Sport Package and 4-Wheel Active Steer (the latter not available with AWD). The Convertible gets standard climate-controlled seats. All are painted in a special graphite color, and feature special wheels, unique front fascia, sport side sills (not on sedan), unique interior trim and red leather seats.

Powertrains and Performance

Powering all 2010 Infiniti G37s is a potent 3.7-liter V6 that growls with 328 hp and 270 pound-feet of torque. Base, Journey and G37x models come standard with a seven-speed automatic transmission featuring manual paddle-shift control and rev-matched downshifts. The Sport 6MT comes with an exclusive six-speed manual transmission. G37s are rear-wheel drive except for the G37x, which is all-wheel drive.

In testing, an automatic G37 Journey sedan sprinted to 60 mph in a remarkably swift 5.4 seconds; the heavier convertible took a bit longer at 6.0 seconds. For G37s equipped with an automatic transmission, fuel economy rings in at an EPA-estimated 18 mpg city/26 mpg highway and 21 mpg in combined driving; Sport 6MTs rate 1 mpg less across the board. The convertible loses an additional mile per gallon relative to its sedan/coupe equivalents in both city and highway driving, and the all-wheel-drive G37x registers 18/25/20 mpg.

Safety

The entire 2010 Infiniti G37 line comes standard with stability control, traction control, front-seat side airbags, full-length side curtain airbags and active head restraints for the front seats. Added safety equipment is included with the optional Technology package, which adds adaptive headlights and pre-crash seatbelts that use the cruise control sensors to detect an impending impact and then automatically pre-tension. Convertibles have standard pop-up rollbars.

In government crash testing, the G37 sedan was awarded a perfect five stars for frontal impact protection for the driver, as well as for side impact protection for all occupants. Frontal impact protection for the front passenger earned it four stars. The G37 also did well in Insurance Institute for Highway Safety crash tests, where it received a top score of "Good" for protection of occupants in both frontal-offset and side-impact crashes.

Interior Design and Special Features

The G37 offers user-friendly controls, excellent build quality and a handsome design -- the latter highlighted by such items as the car's leather-accented magnesium paddle shifters and the Japanese "Shodo" aluminum trim (or optional wood trim). The front seats are comfortable and well-bolstered, while the available sport-styled seats offer even more aggressive bolstering, though they may be a bit too snug for larger drivers.

Both the sedan and coupe/convertible feel like sports cars wrapped in a luxury car package, but the coupe and convertible, with seats that are mounted slightly lower than the sedan's, feel a bit racier. The optional Bose audio system is excellent, and the convertible's headrest-mounted speakers make it even better.

The G37 sedan offers respectable space for rear passengers, with the exception of the narrow center seat, which is mounted rather high, severely compromising headroom and comfort. As expected, the coupe and convertible's backseats are significantly more cramped than those of the sedan.

The coupe's trunk measures a modest 7.4 cubic feet but the rear seatbacks fold down if more space is needed. The sedan's larger trunk accommodates 14 cubic feet of cargo and also includes a center pass-through for longer items. The convertible's trunk will accommodate two golf bags with the top up, but carrying capacity shrinks to about 2 cubic feet (think tissue box and not much more) with the top down.

Driving Impressions

The 2010 Infiniti G37's big V6 serves up thrilling acceleration, but we're not fans of the coarse noises it makes at higher engine speeds. We can't complain about the G's handling, however. This well-sorted Infiniti attacks curves with aggression and precision, yet it remains poised and compliant when driven over less-than-perfect pavement. Think of it as a world-class athlete in evening wear. Steering feel is commendable, particularly with the quicker of the two available ratios (standard on coupes and convertibles, optional on sedans). This sporty setup provides excellent feedback and a pleasant weightiness that builds progressively when cornering.

The seven-speed automatic transmission is mostly praiseworthy. Quick gearchanges are at your fingertips via the steering-wheel-mounted paddle shifters, and downshifts are executed with precise throttle blips to match revs. In testing, however, we've noticed that upshifts, even when in Drive, aren't as smooth as they should be for this class of car. Even so, this automatic makes a strong case for itself versus the optional six-speed manual, which has a pleasing bolt-action feel through the gates but is hampered by abrupt clutch engagement.
