2011 Infiniti G37xS Sedan: Weight & Specs

by Alex Braham 42 views

Let's dive into the specifics of the 2011 Infiniti G37xS sedan, focusing on its weight and other important specifications. If you're curious about how this car measures up in terms of mass and what that means for its performance, you're in the right place. Understanding the weight of a vehicle like the G37xS can tell you a lot about its handling, fuel efficiency, and overall driving experience. We'll break down the numbers and give you some context so you can see why these figures matter.

The 2011 Infiniti G37xS sedan typically has a curb weight of around 3,800 pounds (approximately 1,724 kilograms). This weight can vary slightly depending on the specific options and features included in the model. The curb weight refers to the weight of the vehicle with all standard equipment, fluids, and a full tank of gas, but without any passengers or cargo. Knowing the curb weight is essential for understanding the car's performance characteristics. A heavier car generally feels more planted and stable on the road, which can enhance the sense of security and control, especially at higher speeds. However, it can also impact acceleration and braking performance, as more mass requires more energy to move or stop.

The weight distribution of the 2011 Infiniti G37xS is also a critical factor. While the exact distribution may vary, it's generally close to a 54/46 split between the front and rear axles. This distribution means that the front of the car carries slightly more weight than the rear. Weight distribution affects how the car handles, especially in corners. A more balanced weight distribution can lead to more neutral handling, where the car is less prone to understeer (where the front wheels lose grip and the car wants to go straight) or oversteer (where the rear wheels lose grip and the car's rear end slides out). The G37xS, with its all-wheel-drive system, is designed to mitigate some of the effects of its front-biased weight distribution, providing better traction and stability in various driving conditions. The all-wheel-drive system helps distribute power to the wheels with the most grip, which can counteract the tendency for the front end to push wide in corners.

Impact of Weight on Performance

So, how does the weight of the 2011 Infiniti G37xS impact its performance? A curb weight of around 3,800 pounds places it in the mid-range for sport sedans of its era. This weight, combined with the car's powerful 3.7-liter V6 engine, contributes to its brisk acceleration and confident handling. The G37xS can accelerate from 0 to 60 mph in around 5.5 seconds, which is quite respectable for a car in this class. The weight also affects braking performance. While the G37xS has strong brakes, the car's mass means it requires a reasonable distance to come to a complete stop. Maintaining your brakes is a must, you should check them frequently.

Fuel efficiency is another area influenced by weight. The heavier a vehicle is, the more energy it takes to move it, which translates to lower fuel economy. The 2011 Infiniti G37xS gets an EPA-estimated 19 mpg in the city and 27 mpg on the highway. These numbers are typical for a car with its size, engine, and all-wheel-drive system. If fuel efficiency is a top concern, there are lighter and more fuel-efficient options available, but they may not offer the same level of performance and luxury as the G37xS.

Additional Specifications

Beyond weight, let's look at some other key specifications of the 2011 Infiniti G37xS sedan:

  • Engine: 3.7-liter V6
  • Horsepower: 330 hp
  • Torque: 270 lb-ft
  • Transmission: 7-speed automatic
  • Drivetrain: All-wheel drive
  • Wheelbase: 112.2 inches
  • Length: 188.3 inches
  • Width: 69.7 inches
  • Height: 57.2 inches

These specifications provide a more complete picture of the car's overall design and capabilities. The powerful engine and all-wheel-drive system make the G37xS a capable performer in various conditions, while the car's dimensions contribute to its comfortable interior and balanced proportions. The combination of these factors makes the 2011 Infiniti G37xS a well-rounded sport sedan that offers a blend of performance, luxury, and practicality. Keep in mind that some of these specs can vary. Always verify with your car's specific VIN number to know for sure!

Comparing with Competitors

When considering the 2011 Infiniti G37xS, it's helpful to compare it with its competitors in the sport sedan market. Cars like the BMW 3 Series, Audi A4, and Mercedes-Benz C-Class were all vying for the same buyers. In terms of weight, the G37xS is comparable to these models. For example, the BMW 335i xDrive sedan, which is a direct competitor, has a similar curb weight. However, each car has its own unique characteristics that set it apart. The BMW might offer slightly sharper handling, while the Audi could have a more refined interior. The Mercedes-Benz might prioritize comfort and luxury. The G37xS, with its powerful engine and all-wheel-drive system, offers a compelling blend of performance and value.

When comparing these cars, it's essential to consider your priorities. If you value ultimate handling and driver engagement, the BMW might be the best choice. If you prefer a luxurious and comfortable ride, the Mercedes-Benz could be more appealing. If you want a balance of performance, luxury, and value, the Infiniti G37xS is a strong contender. The G37xS also has a reputation for being reliable. Don't forget to check the car's history.

Owner Reviews and Reliability

To get a better sense of the 2011 Infiniti G37xS, it's worth looking at owner reviews and reliability ratings. Owners often praise the car's powerful engine, comfortable interior, and stylish design. The all-wheel-drive system is also a popular feature, especially for those who live in areas with inclement weather. However, some owners have reported issues such as oil consumption and electrical problems. It's always a good idea to research common problems and maintenance requirements before purchasing a used car. Overall, the G37xS is considered to be a reliable car, but like any vehicle, it requires regular maintenance and care to keep it running smoothly.

Reliability ratings from sources like J.D. Power and Consumer Reports can provide additional insights. These ratings take into account factors such as mechanical issues, electrical problems, and owner satisfaction. While the ratings can vary from year to year, they offer a general indication of a car's reliability. Before buying a G37xS, be sure to check these ratings and read owner reviews to get a well-rounded perspective. And, of course, have the car inspected by a qualified mechanic to identify any potential problems before you make a purchase.

Maintaining Your G37xS

Keeping your 2011 Infiniti G37xS in top condition requires regular maintenance. Here are some essential maintenance tasks:

  • Oil Changes: Regular oil changes are crucial for keeping the engine running smoothly. Follow the manufacturer's recommended oil change interval, typically every 5,000 to 7,500 miles.
  • Brake Service: Inspect the brakes regularly and replace brake pads and rotors as needed. Proper brake maintenance is essential for safety.
  • Tire Rotations: Rotate the tires every 6,000 to 8,000 miles to ensure even wear and prolong tire life.
  • Fluid Checks: Check and top off all fluids, including coolant, brake fluid, power steering fluid, and transmission fluid.
  • Tune-Ups: Perform regular tune-ups, including replacing spark plugs, air filters, and fuel filters, to keep the engine running efficiently.

By following these maintenance tips, you can keep your G37xS running smoothly and reliably for years to come. Regular maintenance can also help prevent costly repairs down the road. Don't skimp on maintenance; it's an investment in your car's longevity.
