Assessing the Benefits: Quattro vs Standard AWD in Cars

Stedmans Garage Insights,

Introduction

When shopping for a new car, one of the key decisions buyers face is whether to get a vehicle with all-wheel drive (AWD) or four-wheel drive (4WD / Quattro). While these systems sound similar, there are some important differences that impact performance, capabilities, and cost. Understanding the pros and cons of AWD versus Quattro can help determine which is the right fit for your needs.

AWD and Quattro have become increasingly popular options in all types of vehicles from sedans to SUVs. AWD provides enhanced traction and control in slippery conditions by sending power to all four wheels. Quattro also sends power to all four wheels but is optimised for off-road activities with extra gearing and features. The Quattro system pioneered by Audi is one of the most well-known AWD technologies and highlights the performance benefits this type of drivetrain can provide.

In this blog post, we’ll take a deep dive into AWD and Quattro to reveal how each system works, their capabilities, and the types of vehicles they are best suited for. Factors like weather, terrain, towing needs, and driving style all impact whether AWD or Quattro is the better choice. Understanding the key differences will make it easier to pick the ideal drivetrain to match your priorities.

What is AWD?

AWD, or all-wheel drive, refers to a vehicle drivetrain capable of sending power to all four wheels. This is different from a traditional two-wheel drive vehicle that only sends power to either the front or rear wheels.

The key advantage of AWD over two-wheel drive is improved traction and handling, especially in wet, snowy, or icy conditions. By powering all four wheels, AWD helps maintain control and forward momentum whereas a two-wheel drive vehicle might lose grip and spin out.

How AWD Works

There are a few different AWD systems, but most work via a centre differential that can actively distribute torque between front and rear axles as needed. This allows the wheels with the most traction to receive the most power.

AWD systems can be full-time, always engaged to the front and rear axles. Or they can be part-time and have the ability to disconnect the rear axle when AWD is not needed, improving fuel efficiency.

AWD Advantages

Some key advantages of AWD include:

  • Better traction and acceleration on slippery surfaces like snow, mud, or gravel
  • Improved handling, cornering, and braking on wet or icy roads
  • Increased control and stability at highway speeds in inclement weather
  • More capability light off-roading or on unpaved surfaces

While adding complexity and cost, AWD improves safety and performance for many drivers, especially in areas with frequent rain or snow. For this reason, AWD has become a very popular option on all types of vehicles from small cars to SUVs.

Comparing AWD and 2WD

Compared to two-wheel drive, AWD provides:

  • Better traction in low-grip conditions like snow, mud, or gravel
  • Improved handling and stability by powering all four wheels
  • Increased capability off-road or on unpaved surfaces
  • More consistent power delivery to avoid wheel spin

However, AWD systems do come with some downsides compared to 2WD:

  • Higher manufacturing costs and complexity
  • Potentially lower fuel economy and increased weight
  • More maintenance and higher repair costs
  • Not needed for normal dry pavement driving

For most everyday driving in ideal conditions, 2WD is perfectly adequate. But for drivers who frequently encounter snow, ice, mud, or other low traction situations, AWD can provide a significant performance and safety advantage.

What is Standard AWD?

Standard all-wheel drive (AWD) refers to a basic four-wheel drive system that sends power to both the front and rear wheels of a vehicle. Unlike more advanced AWD systems, standard AWD typically operates in a fixed 50/50 torque split, meaning power is distributed evenly between the front and rear axles at all times.

Common Features of Standard AWD

Most standard AWD systems have the following components:

  • A transfer case that splits engine power between the front and rear differentials
  • Front and rear differentials to allow each wheel to rotate at different speeds
  • A simple viscous coupling or open differential in the centre
  • No electronic controls or sensors to actively distribute torque

With a basic mechanical AWD system, there is no ability to dynamically shift power between the front and rear axles as conditions change. The static 50/50 torque split provides consistent all-wheel drive traction but lacks some of the performance benefits of more advanced systems.

Examples of Standard AWD Vehicles

Many crossover SUVs and trucks use a standard AWD system to provide improved traction and stability in inclement weather. Some examples include:

  • Toyota RAV4
  • Honda CR-V
  • Subaru Forester
  • Jeep Cherokee
  • Ford Escape
  • GMC Terrain
  • Chevrolet Silverado

While basic in design, standard AWD offers proven capability in low-traction conditions like snow, ice, gravel, and light off-roading. It provides an affordable AWD option for drivers looking for increased traction without the complexity of high-tech systems.

What is Quattro?

The Quattro all-wheel drive system was first introduced by Audi in 1980 and revolutionised the automotive world. Quattro, meaning “four” in Italian, refers to the permanent four-wheel drive that provides enhanced traction and handling.

Unlike other all-wheel drive systems at the time that were part-time, the Quattro system was unique in that it was permanent. This means power is constantly being distributed to all four wheels, not just when slip is detected. The Quattro system was also the first to utilise a torque-sensing centre differential to actively distribute torque between front and rear axles.

Some key features and benefits of the Quattro system include:

  • Torque vectoring – Ability to vary torque to each wheel for improved cornering
  • Limited slip differentials – Help maintain traction during wheel spin
  • Up to 70% rear torque bias – For increased rear-wheel drive feel and dynamics
  • Predictive active control – Proactively adjusts torque distribution

Compared to traditional all-wheel drive systems, Quattro provides superior traction and handling in poor conditions, better high-speed stability, and a more dynamic driving experience. The active nature of Quattro allows it to respond faster and more effectively distribute torque than passive “on-demand” AWD systems.

Some key differences between Quattro and standard AWD systems include:

  • Permanent vs part-time AWD
  • Torque-sensing centre differential vs open differential
  • Active distribution vs reactive distribution
  • Higher rear bias vs balanced 50/50 torque split

In summary, the Quattro system pioneered a new generation of intelligent AWD systems and remains a leading benchmark for performance and capability over 40 years later.

Benefits of Quattro AWD

Quattro all-wheel drive provides enhanced traction and stability in poor weather conditions. The system can transfer torque between the front and rear axles to maintain grip on slippery surfaces. This results in better handling and control compared to two-wheel drive vehicles.

In dry conditions, Quattro improves handling and cornering capabilities. By sending power to all four wheels, the system allows for better acceleration out of corners. The all-wheel drive enables the vehicle to take turns with less understeer and oversteer.

Quattro positively impacts the overall driving experience and safety. Drivers report feeling more confident driving in challenging environments like rain, snow, and gravel.
