2008 Infiniti G37 GSX

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 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.
