2011 Infiniti G37x Sport: Specs, Features, and Performance Overview

When you sit behind the wheel of a 2011 Infiniti G37x Sport, you’re not just driving a luxury sedan—you’re stepping into a blend of Japanese engineering and sporty intent. Infiniti positioned the G37x Sport as the all‑wheel‑drive answer to its rear‑wheel‑drive sibling, aiming to deliver confident handling in rain or shine without sacrificing the brand’s hallmark refinement. Below, we break down the key specifications, standout features, and real‑world performance you can expect from this 2011 model.

Engine and Powertrain

The heart of the G37x Sport is a 3.7‑liter V6 (VQ37VHR), a naturally aspirated engine that churns out roughly 330 horsepower at 6,800 rpm and about 276 lb‑ft of torque around 5,200 rpm. Power is routed through a six‑speed automatic transmission with a manual shift mode, letting drivers hold a gear for a more engaged feel.

What sets the “x” variant apart is Infiniti’s ATTESA all‑wheel‑drive system. It automatically distributes torque between the front and rear axles, sending up to 100% to the rear wheels under hard acceleration but shifting forward bias when traction is needed. This setup helps the G37x Sport launch from a standstill in under six seconds, a figure that nudges the 0‑60 mph mark at about 5.6 seconds according to contemporary road tests.

Exterior Styling and Sport Trim Details

Visually, the Sport trim leans into a more aggressive aesthetic without veering into outright track‑focused design. Key exterior cues include:

• 18‑inch aluminum alloy wheels with a two‑tone finish, larger than the base model’s 17‑inch.
• Unique front grille with blacked‑out surrounds and a subtle “S” badge.
• Dual chrome‑tipped exhaust outlets that give a deeper note on acceleration.
• Rear spoiler and a sculpted rear bumper that enhance the car’s stance.
• Bi‑Xenon HID headlights with adaptive lighting, improving nighttime visibility.

These touches aren’t merely cosmetic; the wider track and sport‑tuned suspension work together to reduce body roll, giving the G37x Sport a planted feel on winding roads.

Interior Comfort and Technology

Inside, Infiniti blends luxury materials with driver‑focused tech. The Sport trim typically features leather‑trimmed seats with perforated inserts, heated front seats, and a driver‑adjustable lumbar support. Ambient lighting can be tuned to three colors, adding a subtle personal touch.

On the tech side, the 2011 model offers:

• Infiniti InTouch™ navigation system with a 7‑inch display and voice command.
• Premium Bose® 12‑speaker audio system, delivering clear highs and a rich bass response.
• Rearview camera with guidelines, a handy aid for parking in tight spots.
• Bluetooth® connectivity and USB ports for smartphone integration.
• Push‑button start and keyless entry, adding a touch of modern convenience.

All of these features are wrapped in a cabin that feels both upscale and driver‑oriented, with a center console layout that keeps the most used controls within easy reach.

Performance Metrics and Driving Dynamics

Beyond raw numbers, the G37x Sport’s performance is defined by its balanced chassis. The sport‑tuned suspension incorporates firmer springs and dampers compared to the standard G37, resulting in a slightly firmer ride that still absorbs most road imperfections. Coupled with a limited‑slip differential in the rear axle, the car feels agile during cornering yet remains predictable for daily driving.

On a typical highway stretch, the G37x Sport maintains a composed cruise at 65 mph, and the steering offers a good amount of feedback without being overly heavy. Braking is confident thanks to four‑wheel disc brakes with ABS, though the brake pedal has a softer feel than a pure sports car, reflecting its luxury pedigree.

Fuel Economy and Practicality

Because the model balances performance with everyday usability, fuel economy sits in the moderate range for a V6 sedan. EPA estimates list about 17 mpg city and 25 mpg highway. Real‑world owners often report similar figures, noting that highway numbers improve when the AWD system operates predominantly in rear‑wheel‑drive mode.

Practicality is another strong suit. The G37x Sport offers a trunk capacity of roughly 13 cubic feet, ample for weekend luggage. Rear seats fold down in a 60/40 split, allowing for larger items when needed. The all‑wheel‑drive system also provides added confidence during inclement weather—a notable advantage over rear‑wheel‑drive rivals.

Safety and Driver Assistance

Infiniti equipped the 2011 G37x Sport with a suite of safety features that were advanced for its time. Standard equipment includes:

• Vehicle Dynamic Control (VDC) stability system.
• Anti‑Lock Braking System (ABS) with Electronic Brakeforce Distribution.
• Front, side, and curtain airbags, plus knee airbags for the driver.
• Traction control and brake‑assist technologies.
• Optional blind‑spot monitoring (available on higher trims).

These systems work together to help the driver maintain control, especially when the AWD system shifts torque during sudden maneuvers.

FAQ

What’s the main difference between the G37 and the G37x Sport?

The G37x Sport adds Infiniti’s all‑wheel‑drive system, sport‑tuned suspension, larger wheels, and a few interior upgrades such as leather seats and a premium audio system. The base G37 is rear‑wheel‑drive and generally lighter, which can translate to slightly quicker acceleration.

Is the 2011 G37x Sport reliable for daily use?

Owners report that the 3.7‑liter V6 engine is durable when serviced regularly. Common maintenance items include timing‑belt replacement around 100,000 miles and periodic fluid changes. Overall, the model is considered reliable for everyday commuting and occasional spirited drives.

How does the G37x Sport perform in winter conditions?

The AWD system provides better traction on snow and wet roads compared to a rear‑wheel‑drive sedan. While it’s not a substitute for dedicated winter tires, pairing the G37x Sport with appropriate tires makes it a competent winter driver.

Does the G37x Sport have a manual transmission option?

No. The 2011 G37x Sport was only offered with a six‑speed automatic transmission. Enthusiasts who prefer a manual must look to older G35 models or other brands.
