2010 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 is one of the most balanced performers in the upscale midsize car class. It offers brisk acceleration, with a V6 reviewers love. Its handling is crisp, particularly in coupe form. Yet its suspension is soft enough to make a daily commute comfortable. It’s one of the few cars that can compete with the athleticism of a BMW 3-Series on the track, and the comfort of a Lexus ES in stop-and-go traffic.
- “I've driven rear-drive automatic G37 sedans both with and without the sport package, and both stand out for their unique combination of refinement, agility, power, and value." -- Car and Driver
- "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,
- "The G37 convertible is a joy to drive." -- Automobile Magazine
- "A great car for eating up pavement...it's quick, handles well and stops effortlessly -- both on-track and off." -- Edmunds
Acceleration and Power
While rivals like the BMW 3-Series or Mercedes-Benz C-Class offer a choice of several engines, the 2010 Infiniti G has only one. A 3.7-liter V6 with variable valve timing, it makes 330 horsepower. While on paper it appears merely average in its class, reviewers are in love with this engine. It has tremendous low-end torque that makes it quick off the line, and a well-tuned exhaust note that reviewers almost never fail to mention.
A six-speed manual is available, but many writers say the seven-speed automatic (with available paddle shifters) is a better choice. Convertibles, we should note, are a bit slower than their sedan and coupe counterparts – a consequence of their heavier weight and less rigid structures.
The EPA estimates that both Coupe and Sedan versions should get 18/26 mpg with the automatic transmission 17/25 with the manual. The G37 requires premium fuel.
- 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
- "G37's eager V6 engine satisfies at any speed. Passing maneuvers are a breeze…The alert and responsive 7-speed automatic is what we would recommend, particularly on models with the Sport Package's paddle shifters." -- Consumer Guide
- 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
Infiniti designed the G37 with an eye toward matching the vaunted BMW 3-Series in track testing. Some reviewers say they’ve pulled it off. Even base models of the rear-wheel-drive G hold their own against canyon-carving favorites like the BMW 3-Series and Audi A4. But available all-wheel-drive and four-wheel-steering make it one of the sharpest handlers in a sporty class. It’s not harsh, however.
Convertible versions are a different story. The Convertible’s three-piece collapsible roof weights 462 pounds. When it is up, it’s in the center of the car and well-balanced. Down, it’s in the trunk – and reviewers say it throws off the car’s handling. The same, however, can be said of other hardtop convertibles, like the Lexus IS convertible.
- “I did my standard 100-mph acceleration run on a secluded freeway on-ramp, one that requires some quick braking before a gradual corner, and the brakes seemed well up to the task, with good pedal response.” -- Automobile Magazine
- “Coupes and sedans are grippy and agile, with little lean in corners. Steering feel is precise and direct.” -- Consumer Guide
- “Can attack a back road with plenty of grip and composure….The BMW 3-series has slightly better steering feel and body control, but the G37 is still quite good on both counts." -- Car and Driver
- "Through all but the most aggressive curves, the car stays as flat as the Arizona desert." -- Motor Trend
- "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
- Four-wheel active steering on the coupe "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
- "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
