2009 Infiniti G37 Performance
This performance review was created when the car was new. Some links may no longer point to an active page.
The G37 Coupe that debuted last year was a spirited performer, able to serve as a comfortable commuter, and on request, as a powerful and agile enthusiast's car. For 2009, the sedan gains all of the performance equipment the coupe boasted last year -- and most writers say the power boost translates well to the four-door body. The convertible, however, would lose any race against its siblings -- the added weight of the hardtop roof costs it some acceleration and some handling balance.
- "Lively and fun, giving way just enough when pushed to keep us interested, while maintaining that balance and comfort necessary to keep the car great to live with as a daily driver." -- AutoWeek
- "Step hard on the gas, and this beautifully appointed, quiet-riding car becomes the automotive equivalent of a snarling attack dog. Seriously fast, with a throaty exhaust rumble." -- Newsday,
- "A great car for eating up pavement...it's quick, handles well and stops effortlessly -- both on-track and off." -- Edmunds
Acceleration and Power
All versions of the 2009 Infiniti G37 draw their power from a 3.7-liter V6 engine with variable valve timing that creates 330 horsepower and 270 pound-feet of torque. That doesn't sound like significantly more power than many competitors, but a number of reviewers have written that it feels like more. A six-speed manual is available, or new for 2009, a unique seven-speed automatic (with paddle shifters) that saves fuel by offering gear ratios suited to a huge variety of driving conditions. Convertible versions lag a bit behind coupe and sedan additions off the line.
The EPA estimates that both Coupe and Sedan versions should get 18/26 mpg with the automatic transmission 17/25 with the manual. The car requires premium fuel.
- "Not surprising, the acceleration times for the brawnier G37 S [sedan] are markedly improved over the less-powerful, five-speed G35 S Zero to 60 now takes only 5.0 sec, with the quarter-mile obliterated in just 13.5 at 105.3 mph. Compared with numbers from our long-term G35 S -- 5.3 and 13.9 at 99.9, respectively -- it's evident the additional 22 hp and two cogs make an appreciable difference." -- Motor Trend
- "G37's eager V6 engine satisfies at any speed. Passing maneuvers are a breeze." -- Consumer Guide
- The engine "stormed out of the lower reaches of the rev range and pulled hard all the way to its 7,500-rpm redline, and the power was easy to manage all the way." -- Edmunds
- "Acceleration was strong and smooth, and the engine makes great music as it happily revs to the red line." -- Forbes
- The convertible "feels quite a bit more deliberate than the coupe thanks to the weight -- 0-60 mph is probably in the high 5-second range now." -- Los Angeles Times
Handling and Braking
Reviewers are generally impressed with the handling balance of the G37, calling it sporty and responsive even in standard trim. But an available four-wheel active steering system takes handling to another level, making the G among the sharpest cornering cars in its class.
Convertible versions lose some of that handling precision, thanks to the 462 pounds of weight added by the retractable hardtop.
- In handling, the G37 is "Among the best in this class. G37S versions are grippy and agile, with little lean in corners. The available Four-Wheel Active Steer System provides particularly sharp moves. Braking is strong and secure." -- Consumer Guide
- "Through all but the most aggressive curves, the car stays as flat as the Arizona desert." -- Motor Trend
- "Transitions through corners are well managed, and there's no bobbing and weaving as you stop accelerating and begin braking or vise versa." -- The Auto Channel
- "The G37 slithered through the corners of the road course with nearly zero body roll, a tell-tale sign of a well developed suspension." -- Road and Track
- "This car simply goes where you point it. At any speed, you could easily thread a needle with this steering." -- The Family Car
- Four-wheel active steering "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." -- Cars.com
- Four wheel steering "works as advertised, but most buyers would be just as satisfied with the basic setup." -- Forbes
- "Thanks in part to the fact that the roof panels are steel and not aluminum, the convertible weighs a staggering 462 pounds more than the coupe. So if you like the way your G37 Coupe drives, just throw a Kawasaki Ninja in the trunk and see how that grabs you. ... the convertible exhibits more tremble and cowl-shake over rough roads than the closed-roof car." -- Los Angeles Times
