Audi A4 Vs S4: Which Luxury Sedan Reigns Supreme?

In this comprehensive comparison, we’ll explore the key differences between the Audi A4 and S4, from exterior styling to fuel economy, to help you make an informed decision.

Design and Features

When it comes to the Audi A4 and S4, the differences in design and features are subtle yet significant. While both models share a common DNA, they cater to distinct preferences and lifestyles.

Exterior Styling Differences

Stepping outside, the A4 exudes a sense of understated sophistication, with clean lines, subtle curves, and a athletic stance. The S4, on the other hand, takes a more dramatic approach, with a bolder front grille, chunkier side skirts, and a more aggressive rear diffuser. The S4’s stance is wider and lower, thanks to its sport-tuned suspension, giving it a more planted look on the road. So, which one gets your attention? Do you prefer the A4’s elegant refinement or the S4’s sporty swagger?

Interior Space and Comfort

Inside, the A4 and S4 boast identical interior dimensions, offering ample room for five passengers and a generous cargo area. However, the S4 takes things up a notch with exclusive features like sport seats, adorned with embossed S logos, and a flat-bottomed steering wheel. The A4, on the other hand, offers a more comfort-focused interior, with available features like heated and ventilated seats, and a panoramic sunroof. Which cabin atmosphere do you prefer? The S4’s high-energy vibe or the A4’s relaxing ambiance?

Infotainment and Technology

In terms of tech, both models are generously equipped, with features like Audi’s Virtual Cockpit, a 12.3-inch digital instrument cluster, and an 8.8-inch infotainment screen. However, the S4 takes the lead with its available premium Bang & Olufsen sound system, boasting 19 speakers and 755 watts of power. The A4, while still well-equipped, sticks to a more modest sound system. When it comes to staying connected on the go, do you prioritize raw audio power or clever convenience features?


Performance and Handling

When it comes to the performance and handling of the Audi A4 and S4, there are some key differences that set these two models apart.

Engine Options and Horsepower

One of the most notable differences lies under the hood. The Audi A4 comes equipped with a 2.0-liter turbocharged engine, producing 248 horsepower and 273 lb-ft of torque. While this is certainly respectable, the S4 takes things to the next level with its 3.0-liter turbocharged V6 engine, pumping out 349 horsepower and 369 lb-ft of torque. That’s a significant increase in power, making the S4 feel decidedly more athletic and responsive on the road. But what does this mean in practical terms? For starters, the S4 can sprint from 0-60mph in just 4.4 seconds, while the A4 takes a more leisurely 5.6 seconds to reach the same speed. That’s a difference of over a second – not insignificant when you’re merging onto a busy highway or accelerating through a gap in traffic.

Transmission and Drive Types

Another key area where the A4 and S4 diverge is in their transmission and drive types. The A4 comes with a seven-speed dual-clutch automatic transmission, which is smooth and efficient, but perhaps not the most engaging to drive. The S4, on the other hand, gets an eight-speed automatic transmission with paddle shifters, allowing for more driver control and input. Additionally, the S4 features Quattro all-wheel drive as standard, while the A4 offers it as an option. This gives the S4 added traction and stability, particularly in inclement weather or when pushing the limits on twisty roads.

Suspension and Steering

Finally, there are some notable differences in the suspension and steering setups of the A4 and S4. The A4 has a more comfort-oriented suspension, which is great for daily driving but may feel a bit soft when pushed hard. The S4, by contrast, features a sport-tuned suspension with adaptive dampers, which provides a more dynamic and responsive driving experience. The S4 also gets a more direct and precise steering system, which makes it feel more agile and connected to the road. While the A4 is still a pleasure to drive, the S4 is undeniably more engaging and fun for enthusiasts.


Price and Value

When it comes to investing in a luxury vehicle like the Audi A4 or S4, one of the most significant considerations is the price tag. After all, you want to make sure you’re getting the best value for your hard-earned money. So, let’s dive into the nitty-gritty of pricing and value to help you make an informed decision.

Base Model Pricing Comparison

The base model Audi A4 starts at around $39,000, while the S4 begins at approximately $49,000. That’s a significant difference, but what do you get for that additional $10,000? The S4 boasts more powerful engine options, sport-tuned suspension, and premium features like heated and ventilated front seats. However, if you’re on a budget and don’t need all the bells and whistles, the A4 still offers an impressive list of standard features, including a 10.1-inch infotainment screen and advanced safety features like forward collision warning.

Trim Levels and Upgrade Options

Both the A4 and S4 offer various trim levels and upgrade options to tailor your driving experience to your preferences. The A4 comes in Premium, Premium Plus, and Prestige trims, while the S4 offers Premium Plus and Prestige trims. As you move up the trim levels, you’ll gain access to features like adaptive cruise control, lane departure warning, and a 12.3-inch digital instrument cluster. Additionally, you can choose from various packages, such as the Convenience Package (which adds features like a power moonroof and parking sensors) or the Sport Package (which includes sport-tuned suspension and 18-inch wheels).

Cost of Ownership and Maintenance

While the purchase price is an essential consideration, it’s not the only factor to think about. You’ll also need to consider the cost of owning and maintaining your Audi over time. According to various sources, the Audi A4 has an estimated five-year cost of ownership of around $60,000, while the S4 comes in at around $70,000. These estimates include fuel, maintenance, repairs, and insurance costs. However, it’s worth noting that the S4’s more powerful engine may lead to higher fuel costs over time. Be sure to factor these expenses into your decision-making process to ensure you’re prepared for the long-term commitment of owning a luxury vehicle.


Safety and Reliability

When it comes to safety and reliability, both the Audi A4 and S4 have a lot to offer. But, how do they stack up against each other? Let’s dive in and explore the crash test ratings, safety features, reliability, durability, and warranty and maintenance requirements of these two popular Audi models.

Crash Test Ratings and Safety Features

Both the Audi A4 and S4 have received top-notch safety ratings from reputable organizations like the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). The A4 earned a 5-star overall safety rating from the NHTSA, while the S4 received a Top Safety Pick+ rating from the IIHS. These ratings are a testament to the robust safety features found in both models, including:

  • Advanced airbag systems
  • Electronic stability control
  • Anti-lock braking systems (ABS)
  • Lane departure warning and assist systems
  • Forward collision warning and automatic emergency braking
  • Blind-spot monitoring and rear cross-traffic alert
  • Adaptive cruise control with stop-and-go functionality

But, what sets the S4 apart from the A4 is its more advanced safety features, such as a 360-degree camera system and a head-up display that provides critical safety information directly in the driver’s line of sight.

Reliability and Durability Comparison

When it comes to reliability and durability, both the Audi A4 and S4 have a reputation for being dependable and long-lasting. According to various studies and surveys, both models have consistently ranked high in terms of reliability, with many owners reporting low maintenance costs and few mechanical issues.

However, the S4’s more powerful engine and advanced systems may require more frequent maintenance and repairs compared to the A4. Additionally, the S4’s more complex systems may be more prone to technical issues, which could impact its overall reliability.

Warranty and Maintenance Requirements

Both the Audi A4 and S4 come with a comprehensive warranty package that includes:

  • A 4-year/50,000-mile new vehicle limited warranty
  • A 4-year/50,000-mile powertrain limited warranty
  • A 12-year/unlimited-mile corrosion perforation limited warranty
  • 4 years of roadside assistance

In terms of maintenance requirements, both models require regular scheduled maintenance, including oil changes, tire rotations, and brake pad replacements. However, the S4’s more advanced systems may require additional maintenance tasks, such as software updates and inspections.

While both models are relatively low-maintenance, the S4’s more complex systems may require more frequent visits to the dealership or authorized service center.


Fuel Economy and Efficiency

Fuelling your car is an inevitable part of vehicle ownership, and with the ever-growing concerns about climate change, fuel economy has become a crucial aspect to consider when buying a new ride. The Audi A4 and S4 are both known for their performance, but which one fares better when it comes to fuel efficiency?

Gas Mileage Comparison

Let’s dive straight into the numbers. The Audi A4’s fuel economy varies depending on the trim level and engine choice. The base model A4 2.0T FS with the front-wheel drive (FWD) configuration achieves an estimated 27 miles per gallon (mpg) in the city, 37 mpg on the highway, and 31 mpg combined. Move up to the A4 2.0T Quattro, and the numbers drop slightly to 25 mpg city, 34 mpg highway, and 28 mpg combined.

In contrast, the Audi S4’s fuel economy is understandably lower due to its more powerful engine. The S4 achieves an estimated 21 mpg city, 30 mpg highway, and 25 mpg combined. While these numbers may seem less impressive, it’s essential to remember that the S4 is built for speed and agility, making it a worthy trade-off for those who crave performance.

Fuel Types and Engine Options

The Audi A4 offers two engine options: a 2.0-litre turbocharged inline-four cylinder, and a more potent 3.0-litre turbocharged V6 in the A4 45 TFSI Quattro. The S4, on the other hand, features a 3.0-litre turbocharged V6 engine as standard. While both models only come with petrol options, it’s worth noting that the A4 2.0T can run on regular fuel, whereas the S4 requires premium fuel.

Emissions and Environmental Impact

With growing concerns about carbon emissions, it’s essential to consider the environmental impact of your vehicle. The Audi A4 and S4 both have relatively low emissions, with the A4 emitting 166 grams of CO2 per kilometer (g/km) and the S4 emitting 187 g/km. While these numbers are still higher than many hybrid or electric vehicles, they’re relatively competitive within the luxury sedan market.
