2012 INFINITI G37 Road Test

Jennifer Geiger

With Infiniti's G lineup, there's something for everyone. The brand's best-selling car is offered in sedan, coupe and convertible body styles and in several performance levels, from the base G25 sedan (reviewed separately) to the high-performance IPL version of the G37 coupe, which is covered in this review. See them all compared here.

The 2012 Infiniti G37 IPL coupe is fast and agile, and it puts the P in Performance, but it's not cheap. Yes, you get an extra bit of power, but you're also stuck with a more brittle ride and ear-numbing road noise.

Moreover, the G37 coupe is already a winner in the class; the IPL version increases the price, but it doesn't add much value.

The IPL treatment adds a boost of horsepower, a sport-tuned suspension and specific interior and exterior trim. The coupe was the first vehicle in the IPL stable, and it will be joined by a convertible model later this year. Click here for our review of the G37 sedan.

Smooth Power, Rough Ride
Driving the IPL home after a long workweek was like slamming a shot of espresso. It's fast and exhilaratingly fun to drive … but so is the base G37 coupe. The IPL adds 18 hp, but I really couldn't feel the difference.

Compared with the V-8 engines in rivals like the BMW M3 (414 hp) and Lexus IS-F (416 hp), the IPL's 348-hp, 3.7-liter V-6 may look feeble by comparison, but it can at least play in the same arena. Its plentiful power is robust from a stop and smooth and str...

Smooth Power, Rough Ride
Driving the IPL home after a long workweek was like slamming a shot of espresso. It's fast and exhilaratingly fun to drive … but so is the base G37 coupe. The IPL adds 18 hp, but I really couldn't feel the difference.

Compared with the V-8 engines in rivals like the BMW M3 (414 hp) and Lexus IS-F (416 hp), the IPL's 348-hp, 3.7-liter V-6 may look feeble by comparison, but it can at least play in the same arena. Its plentiful power is robust from a stop and smooth and strong at higher speeds, and it has the soundtrack to back it up. It snorts and burbles upon takeoff and then fades to a more subtle but still sporty note on the highway. (See the three models compared here.)

Our test car was equipped with a six-speed manual transmission; a seven-speed automatic with paddle shifters is also available. The short-throw stick makes it easy to snap through shifts, though at times the action felt balky, and 1st gear occasionally required some force.

The G37 IPL is EPA rated at 17/25 mpg city/highway, beating the M3 (14/20 mpg) and IS-F (16/23 mpg) by a few digits. All three cars require premium fuel. I drove the Infiniti 182 miles (70 percent highway and 30 percent city) and got 19 mpg.

Most of those miles hurt, however. The IPL sport suspension has had most of the regular G37's comfort tuned out of it. The ride is firm, bordering on harsh. City potholes jar and resonate through the car. Things improve on the highway, but it still feels taught and jumpy over highway expansion joints. Its huge 19-inch wheels and low-profile summer tires don't help matters.

The IPL shines in the agility department, however, with crisp cornering and virtually no body lean. Overall, the steering is responsive. It feels light around town but firms up at higher speeds.

A Tight Fit
Rather than cramped, the front of the IPL's cabin feels cozy, especially the heavily bolstered sport seats. I found them snug, especially while cornering, but some people may find them too constrictive.

My 5-foot-5 self had more than enough headroom and legroom in the driver's seat, though the moonroof, which is standard in the IPL trim level, steals a couple of inches. My 6-foot-1 front passenger had to lower his seat in order to fit, which wasn't the most comfortable position. Up front, there are 37.7 inches of headroom and 43.8 inches of legroom. Comparatively, the M3 coupe has a bit more front-seat headroom but less legroom. The IS-F sedan offers slightly less headroom but a bit more legroom.

Like all G coupes, the backseat accommodates only two passengers; I missed the utility of four doors and seating for five. A long, heavy door and sloping roofline means getting into the backseat requires the usual stoop-twist coupe dance. No big deal for most, but not an easy feat when balancing a child-safety seat, which I shoehorned back there.

It's very tough to get the right fit. A rear-facing convertible seat pushed the front passenger seat all the way forward, making it unusable. With the child seat in a forward-facing position, the heavily bolstered backseat made it tough to find a flat section to nestle it into. The biggest challenge, however, was connecting the top tether strap. Its anchor is in the far corner of the shelf behind the seat.

Smaller adults should have an easier time fitting in the backseat; larger adults will be uncomfortable. Friends joked that the IPL looked like the Batmobile, but the backseat was like the Batcave. It's set very low to the ground, putting passengers in an uncomfortable knees-up position. The IPL has 34.5 inches of rear-seat headroom and 29.8 inches of legroom. Both the M3 coupe and IS-F sedan offer several inches more of each.

The IPL's trunk has a narrow-ish opening and a meager 7.4 cubic feet of cargo volume. The M3 has 11.1 cubic feet and the IS-F has 13.3 cubic feet. The IPL's backseat folds in a single piece rather than a 50/50 split.

Cabin Comforts
The IPL's refined interior is trimmed in premium-feel materials and has a dynamic look. Brushed aluminum looks classy, as does Infiniti's hallmark analog clock. Soft-touch leather and plastic pieces are in all the necessary contact places. Red contrast stitching adds a nice pop to the otherwise completely graphite-colored interior. Monaco Red is another IPL-exclusive interior color.

An intrusive and unacceptable level of tire thrum and general road noise at highway speeds ruined the ambiance, however, stopping conversation. My passenger's phone rang, and he opted to let it go to voice mail.

Infiniti gets an A+ for its navigation system. It's one of the easiest control interfaces out there, with an intuitive touch-screen and a large control knob that's easier to reach. What's even better is the navigation system doesn't absorb the climate and audio controls. Those are separate knobs, which are clearly marked and reachable.

Features & Pricing
The 2012 Infiniti G37 IPL starts at $50,695 including an $895 destination charge. Equipped with an optional trunk mat, first-aid kit and cargo net (a $200 package), my test car topped out at $50,895. BMW's M3 starts at $62,295 and the Lexus IS-F at $62,175. The IPL may seem like a bargain, but the base G37 with the 330-hp, 3.7-liter V-6 starts at just $38,695. If you want a manual transmission, you need to jump up to the $45,095 G37 Sport coupe, which also nets you a Bose stereo, limited-slip differential, a navigation system with voice recognition, driver's seat/mirrors/steering-wheel position memory, a backup camera with sonar system and a moonroof. It's still a bargain compared with the IPL.

The G37 is one of those cars whose styling had aged well … until the IPL team got ahold of it. Infiniti IPL-ified it with gaudy and aggressive body cladding, transforming it into a cartoon version of itself. Sure, the unique front and rear bumpers, side sills, rear spoiler and wheels add visual drama, but they look overblown to me.

Safety
In Insurance Institute for Highway Safety crash tests, the 2012 Infiniti G37 coupe received the highest score, Good, in frontal offset and side-impact tests. It scored Acceptable in roof strength and Marginal in rear-impact testing.

The G37 comes standard with a full complement of airbags including front, front-seat-mounted side-impact air bags and side curtain airbags for front and rear seats. As is required of all 2012 models, antilock brakes and an electronic stability system are standard. Click here for a full list of safety features.

The G37's fetching curves come at the price of visibility. A small, dramatically raked rear window, thick pillars and narrow side windows compromise visibility. The IPL's standard backup camera improves matters, but it could really use a blind spot warning system; one isn't available. Adaptive cruise control with forward collision warning is optional on other versions of the G37 but unavailable on the IPL model.

In the Market
The main problem here is a good one for Infiniti: In regular form, the refined G37 coupe is already incredibly capable and exciting, which sets the bar pretty high for the IPL. Why pay a hefty price premium for the IPL? Its ride is too firm, road noise is off the charts and you get only 18 more horsepower — which it didn't really need in the first place.

Compared with the competition, the IPL may look like a deal, but to go up against the Ms and Fs of the world, it needs to offer more.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
