2021 Audi S4

The 2021 trim lineup remains the same with 3 trims on offer- Premium, Premium Plus, and Prestige. As you move up the trim level, more technology features and driver assistance tech get added. Here is an overview of all the trims and features.

Which Trim should you buy?

We will definitely suggest the mid-range Premium Plus trim as usual, as it offers a range of impressive creature comforts and gizmo. Alternatively, you can also equip this trim with the Convenience package to get almost all the privileges of the top-draw trim.

The Audi S4 can return a mileage of 20mpg in the city and 28mpg on the highway, with a combined MPG of 23. These figures are decent enough for a V-6 powered vehicle. With a fuel tank capacity of 15.3 gallons, the S4 can shell out a driving distance of 306 miles in the city and 428 miles on the interstate. On average, the S4 should be able to offer you around 351 miles of combined driving range. The S4 isn’t particularly a family-friendly sedan in terms of economy, but it is still more efficient than most performance-oriented sedans out there in the market. 

The Audi S4 offers more fuel economy than its Mercedes-AMG c43 but loses out to its Bavarian counterpart. The BMW M340i is the overall best choice with its fine balance of performance and fuel efficiency, offering the best mileage in this segment.

Audi’s cars have always featured drool-worthy interior designs with intricate little details that stand out when you catch a first glimpse of the cabin. The 2021 Audi S4 interior reflects on the same philosophy featuring an elegant yet simple cabin that looks appealing to the eyes. Driver functionality is also the key element here, owing to the sporty nature of the sedan. Standard interior bits include 12-way power-adjustable sport seats with a 4-way power-lumbar and heating and massage function, which is standard on all three trims. The seats are covered in leather or Alcantara upholstery, both of which add to the ambiance of the cabin. Standard mood lighting creates a cozy atmosphere for the passengers seated. 

The Convenience package adds a heated steering wheel and memory functionality to the driver’s seat. Customers also get a variety of interior colors and stitching patterns, to upgrade their cabin as per their incline. The trunk behind can only store 12 cubes of space, which is pretty underwhelming for a family on a trip. Still, the trunk may fit in 3 large suitcases with ease, making it ideal for daily use. The rear seats can be folded in a 40/20/40 split at the click of a button to accommodate some of your monthly groceries, while 4 cupholders and center armrest storage provide further convenience.

The Audi S4 offers exquisite levels of luxury with its roomy interior dimensions and opulent material quality. The S4 has the smallest trunk in its segment though, which puts it at a disadvantage compared to rivals.

The standout interior features onboard the Audi S4 sedan are:

• Leather/Alcantara seating upholstery
• 12-way power-adjustable sport seats with a 4-way power-lumbar and heating and massage function
• Brushed Aluminum inlays
• Available Driver's front seat memory

What’s there to keep you entertained?

Audi’s love affair with futuristic technology continues inside the 2021 Audi S4 Sedan. A sizable 10.1-inch touchscreen displays all the infotainment features in crisp graphics. Audi’s intuitive MMI technology provides haptic feedback to the driver’s touch responses. Voice control enables an even more natural way of communication between the driver and the interface. 

Almost all the modern infotainment features are also integrated into the touchscreen, including the likes of wireless Apple CarPlay, Android Auto, HD Radio, and Bluetooth. A 10-speaker sound system plays your music on the go, while a 19-speaker 3D sound system from Bang & Olufsen is also available to woo audiophiles. 

The optimal Audi Virtual cockpit plus brings impressive features like a high-resolution 12.3-inch screen, three display modes and relays your location in Google Earth or via a 3D map. Customers can also enjoy the privilege of the available Audi Connect services, which brings to the table navigation directions, an in-car Wi-Fi hotspot, and much more. Other technological enhancements like SiriusXM satellite radio, wireless charging, and two rear USB ports for charging complete a brilliant tech suite.

In a nutshell, the 2021 Audi S4 has a plethora of cutting-edge gizmo like:

• 10.1-inch MMI touchscreen

The 2021 Audi S4 Sedan exterior design is widely related to its A4 sibling, but the S4 possesses several visual differences like a unique Singleframe grille with subtle vents and numerous aluminum-look accents. For 2021, the S4 turns on the style with its updated 18-inch wheel design and a new front and rear fascia. In the rear, a combination of the diffuser with a quad-exit exhaust setup and an integrated trunk spoiler looks sporty as hell. The S4 also makes a style statement with its S-tuned quad exhausts, LED daytime running lights, and a colorful palette of 8 exterior colors. 

The exterior dimensions of the S4 remain unchanged for 2021. The exterior dimensions are well on par with other sedans in the class. The S4’s low ground clearance combined with Quattro all-wheel-drive grant it more stability and grip.

The Audi S4 stands out amongst the crowd with its unique styling elements like:

• Auto-dimming exterior mirrors
• 18-inch 5-Y-spoke design wheels
• Matrix-design LED headlights
• Integrated trunk spoiler
• LED daytime running lights

The 2021 Audi S4 pays equal emphasis on performance as well as the safety of its passengers. Thus, to fulfill that promise, the S4 includes a host of standard safety features like LED headlights with auto high beams, rain-sensing wipers, a rearview camera, lane departure warning, and forward collision detection with autonomous emergency braking. By opting for the higher trim levels, the driver unlocks new safety techs like 

• Audi adaptive cruise control with traffic jam assist and turn assist
• Blind-spot monitoring with rear cross-traffic alert
• A heads-up display
• Park assist
• Vehicle exit warning

Audi also provides a unique top view camera system that relays a birds-eye view of your car’s surroundings. You can also add matrix LED headlights to the table that enhance both your vehicle’s style and safety quotient.

2021 Audi S4 Sedan vs 2021 Mercedes-AMG C43 Sedan

The battle between two of Germany’s greatest automakers has always stirred up a lot of heat, and this duel is no different. The Merc may have the upper hand with a more powerful engine, but the S4 sends out a stern reply with a 0-60 mph time just 0.1 seconds faster than the Merc. However, the Merc’s AMG credentials prove to be the decisive factor in the handling sector, as it is more adept than the Audi in scaling corners. Both the sedans are almost neck-to-neck in terms of practicality, although the Mercedes offers slightly more storage. The Merc feels more like a raw performance-oriented sedan rather than a sports cruiser like the Audi S4. The choice is yours.

2021 Audi S4 Sedan vs 2021 BMW M340i Sedan

Audi and BMW’s fierce rivalry continues with the Audi S4 and the BMW M340i. However, the BMW M340i has clear bragging rights over its rival in the power and speed charts, fuel economy, handling dynamics, and cargo space. Technology-wise, both the sedans are evenly matched. The BMW can get pricier as you opt for more features though, but we still believe it is still worth all the bucks.

2021 Audi S4 Sedan vs 2021 Genesis G70 Sedan

The Genesis G70 is a welcome change over its aggressive German rivals in this segment. It has a snug old-school sedan-like feeling to it, without trying to overdo its sportiness. The G70 is a powerful sedan in its own sense, but the Audi S4 is at an advantage with more power under its hood. The G70 offers similar levels of luxury as the S4. Audi’s tech suite is still one of the finest in its business, but the G70 offers more trunk room. In a nutshell, the Genesis G80 is a great out-of-the-box choice in its pricey segment, although the Audi S4 is an amazing sedan in its own sense.

The 2021 Audi S4 Sedan is an excellent driver’s vehicle that offers luxury and performance in a single package. Audi’s Quattro AWD system and the powerful V-6 make the sedan a treat to drive. The best part about this sedan is the convenience of taking it out on daily errands as well as fun weekday trips with your family. The S4 feels right at home with its cutting-edge technology and racetrack-oriented vibes and is definitely one of Audi’s finest creations.
