2008 INFINITI G37 Review

from the Cars.com expert editorial team

Cars.com's Joe Wiesenfelder walks you through the 2008 Infiniti G37 S.

Vehicle Overview
When Infiniti’s first G35 coupe stormed onto the scene in 2002, it proved a worthy alternative to BMW’s 3 Series — the best you could get for $35,000 at that time. Now, as the new 3 Series reassumes control of the segment with a rip-snorting 300 horsepower in the 335i, it seems time for Infiniti to hatch the latest G.

That the redesigned G35 sedan already provided a compelling alternative to the 3 Series didn’t matter. Infiniti decided against matching that car’s 306-hp, 3.5-liter V-6, instead building a 3.7-liter engine for the appropriately named G37 coupe. The larger V-6 sends an estimated 330 hp to the rear wheels through a five-speed automatic or six-speed manual transmission.

Three trim levels are available: base, Journey and Sport 6MT, which is sold exclusively with the manual. Infiniti G37s hit dealerships in August 2007.

Exterior
The G37 looks much like you’d expect for a two-door offshoot of the new G35. The curvaceous body integrates large — but fairly subtle — fenders, while the bumper boasts one of the more sinister interpretations of the familiar air dam and side portals you see on many cars. Twin L-shaped headlights flank the slatted grille. The taillights aren’t all that different from those on the previous G35 coupe.

Adding the Sport package to a G37 Journey gets you a sport-tuned suspension, exterior ground effects and massive 14-inch front disc brakes — the same size as those on a Corvette Z06. The Sport pa...

Twin L-shaped headlights flank the slatted grille. The taillights aren’t all that different from those on the previous G35 coupe.

Adding the Sport package to a G37 Journey gets you a sport-tuned suspension, exterior ground effects and massive 14-inch front disc brakes — the same size as those on a Corvette Z06. The Sport package also swaps the G37’s standard 18-inch alloy wheels for 19-inchers. The G37 Sport 6MT includes all the enhancements standard.

Infiniti’s 4-Wheel Active Steer system is optional on the Journey and 6MT. It turns the rear wheels as well as the front ones, which purportedly improves high-speed handling and makes it easier to turn at parking-lot speeds.

At 183.1 inches long and 71.8 inches wide, the G37 is nominally bigger than the 335i coupe. It’s even a bit wider than the G35 sedan.

Interior
Apart from having a smaller backseat with room for two instead of three, the G37’s cabin is not much different from that of the G35 sedan. The coupe’s interior is a vast improvement over the first-generation G35, and now features such novelties as aluminum trim modeled after Japanese Washi paper.

Standard features include power front seats, automatic climate control, a six-speaker CD stereo and leather upholstery. Heated seats with power side bolsters, a moonroof and a navigation system with real-time traffic monitoring are optional.

Under the Hood
Sporting an elaborate air induction system similar to (no surprise) BMW’s Valvetronic, the 3.7-liter V-6 makes an estimated 330 hp and 270 pounds-feet of torque. It teams with a five-speed automatic transmission in the G37 base and Journey, while the Sport 6MT gets a six-speed manual. Cars with the Sport package include a limited-slip differential for better traction while cornering.

Infiniti estimates that the G37’s engine actually delivers around 1 mpg better gas mileage than the 3.5-liter V-6 in the G35. With the EPA’s revised fuel economy ratings for 2008, that should translate into roughly 21 mpg in combined city and highway driving for a manual-equipped G37.

Safety
All G37s come standard with six airbags, including side-impact airbags for the front seats and side curtain airbags for both rows. Active head restraints, four-wheel-disc antilock brakes, traction control and an electronic stability system are also standard.

Infiniti’s Intelligent Cruise Control, which can match highway speeds with the car ahead, is optional. It includes a Preview Braking function that preloads the brakes for faster response if the car in front slams on its brakes. Also optional are pre-crash seat belts that can tighten in response to emergency braking, as well as adaptive headlights that can swivel several degrees to better illuminate corners.

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.
