What is the Difference Between "Four Wheel Drive" and "All Wheel Drive?"

The terms "all-wheel drive" (AWD) and "four-wheel drive" (4WD) are often used interchangeably to describe drivetrain systems that provide power to all four wheels of a vehicle. While both systems offer enhanced traction and off-road capabilities compared to traditional two-wheel-drive setups, there are key differences between AWD and 4WD systems in terms of operation, functionality, and performance. Understanding these distinctions can help you choose the right drivetrain for your driving needs. Here's a breakdown of the differences between all-wheel drive and four-wheel drive: AWD (All-Wheel Drive): All-wheel drive systems continuously send power to all four wheels of the vehicle, typically through a combination of differentials, sensors, and electronic control systems. AWD systems are designed to optimize traction and stability in various road conditions, providing better grip on wet, slippery, or uneven surfaces. AWD is commonly found in crossover SUVs, sedans, and performance vehicles to enhance handling and performance on both dry and challenging road surfaces. Key Features of AWD: Constantly active system that automatically distributes power to all wheels. Ideal for everyday driving and varying road conditions. Typically prioritizes on-road traction and handling over off-road capability. Can vary power distribution between front and rear wheels depending on traction needs. Often features stability control and traction management systems for improved handling. 4WD (Four-Wheel Drive): Four-wheel drive systems are designed to provide power to all four wheels of the vehicle but are typically selectable or engageable by the driver. 4WD systems often feature a transfer case with low-range gearing for enhanced off-road performance, allowing drivers to toggle between two-wheel drive and four-wheel drive modes depending on terrain and driving conditions. 4WD is commonly found in pickup trucks, SUVs, and off-road vehicles built for rugged terrain and challenging environments. Key Features of 4WD: Selectable system that allows drivers to engage or disengage four-wheel drive mode. Ideal for off-road driving, towing, and traversing rough terrain. Often includes low-range gearing for enhanced torque at low speeds. Provides increased traction and power delivery to overcome obstacles and challenging road conditions. Requires driver input to engage four-wheel drive mode, typically via a switch or lever. In summary, the main differences between all-wheel drive and four-wheel drive lie in their functionality, operation, and intended use. All-wheel drive systems are automatic and continuously active, providing enhanced traction and stability on various road surfaces , while four-wheel drive systems are selectable and often geared towards off-road performance and versatility. Both AWD and 4WD systems offer benefits in terms of traction, handling, and performance, depending on the driving conditions and terrain. When choosing between AWD and 4WD, consider your driving needs, preferences, and the types of terrain you will encounter. For everyday commuting and diverse road conditions, AWD may be a suitable choice. If you require enhanced off-road capabilities, towing capacity, or the ability to navigate challenging terrain, a 4WD system may be more appropriate. Consult with automotive experts or test drive different vehicles to determine which drivetrain system best suits your driving style and requirements.

Do Tires Expire?

Image
  Do tires expire is a question that our customers often ask. For years many motorists have relied only on tread depth to know when it is time to replace them. Unfortunately, the age of your tires is also a factor. Over time, tires can dry out and crack. Excessive heat and sunlight contribute to this and can cause tire to unexpectedly fail, even when there is plenty of tread remaining on the tire . Tire manufacturers offer different opinions regarding how long tires will last, but the National Highway Transportation Safety Administration (NTHSA) recommends that you replace tires after six years . How do you know how old your tires are ? The best way to know the age of your tires is to check the Department of Transportation (DOT) code. The manufacturer stamped it in the sidewall of your tire. DOT numbers identify the manufacturer and the make of tires, but they also tell you when the tires were made . The last four digits of your tires’ DOT code tell the month and year of manufa...

What is a Belt Tune Up?

Image
A Serpentine Belt is the rubber Drive Belt that causes the pullies on your car's Alternator, Air Conditioning Compressor, Water Pump, and Power Steering Pump to rotate and to create electrical and mechanical power. Rotation of the alternator creates your car's electrical power. Gas powered vehicles have one or more Drive Belts, at least one Belt Tensioner, and they may have one or more Idler Pulleys. Belt Tensioners insure that the Alternator, A/C Compressor, Water Pump, and Power Steering Pump continue to spin with the rotation of the engine. Idler Pulleys are simply pulleys that do not drive other components. Idler Pulleys are used to route the Serpentine Belt.  With use, a Serpentine Belt will stretch and wear.  Belt Tensioners and Idler Pulleys also wear, and this will cause additional belt wear. When a Serpentine Belt breaks, the components that it drives will not longer function. Because of this, Sant Automotive recommends that you replace your Serpentine Belt(s), Idler ...

What Do Spark Plugs Do?

Image
  Spark Plugs are the small electrical parts that provide the power to ignite the fuel in gasoline powered devices. As electricity passes between the Spark Plug's electrodes, gasoline ignites causing an explosion that powers your vehicle. Spark Plugs fire once every two engine rotations. This means that if your engine is running at 800 RPMs, your Spark Plugs will fire 400 times per minute. The heat produced by these explosions causes the Electrodes to wear which increases the gap between the Electrodes. The increased gap causes your vehicle to use more fuel to produce the same amount of power.  Worn Spark Plugs reduce Gas Mileage, and unburnt fuel will damage your car's Oxygen Sensors and its Catalytic Converter. Also, the longer that plugs stay in a vehicle, the more likely they are to become stuck in the engine's cylinder head. If a spark plug breaks, it can be very expensive and time consuming to extract it. For these reasons, Sant Automotive recommends that you change y...
