Is the Audi A4 S line equivalent to the S4?
The S-Line A4 is little more than an A4 with a few body kit components and a slight increase in power. The S4 is a totally distinct vehicle. For the S4, everything has been upgraded, including the interior, suspension, and engine.
What does the S in the Audi S4 stand for?
Sport. These vehicles are compared to supercars in terms of both price and characteristics. The “RS” (“Sport”) specification level of the standard model range of Audi is clearly above the highest performance “top-tier” trim level offered by the automaker. 8 Sept 2020.
Is an Audi S4 a quick vehicle?
The B5 S4’s third-generation 2.7-liter twin-turbo (‘biturbo’) V6 engine is featured in the powertrain details[5] (parts code prefix: 078, identification codes: AGB, AZB, APB). The engine has a cast iron cylinder block and two lightweight aluminum alloy cylinder heads, among other details. The valvetrain consists of twin hybrid-driven (timing belt and roller chain) double overhead camshafts with 30 valves (five valves per cylinder),[10][11] variable valve timing for the inlet valves, and 30 valves (five valves per cylinder). Two parallel water-cooled BorgWarner K03-series turbochargers pressurize the intake air; the charged air is cooled by two side-mounted air-to-air intercoolers (SMICs). It has a displacement of 2,671 cubic centimeters (163.0 cu in) and is capable of producing 400 Nm (295 lbft) of torque at 1,850 rpm and 195 kW (265 PS; 261 bhp) of mechanical power at 5,800 rpm. A BoschMotronic ME 7.1 (7.0 in North America) electronic engine control unit (ECU) was used for engine control, which enabled it to comply with the EU-3D emissions standard. For all vehicles sold in the US, the engine’s output was decreased to 184 kW (250 PS; 247 hp) and 350 Nm (258 lbft) in order to comply with US emissions rules (identification code: APB).
The Torsen T-2 quattro permanent all-wheel drive system and a six-speed C90 manual transmission were standard features, same like in the preceding S4 (parts code prefix: 01E, identification code: DSY, gear ratios: first: 3.500, second: 1.889, third: 1.231, fourth: 0.967, fifth: 0.806, sixth: 0.684). Final drive ratio is 4.111 (parts code prefix: 01H, identification code: DQA). For the first time, a five-speed ZF5HP19tiptronic automatic transmission with the prefix 01V was offered as an option. [5]
The B5 S4 is the fastest saloon/sedan in the Audi model line and one of the fastest saloon/sedans in the world at the time, with a claimed 0100 km/h (0.062.1 mph) acceleration time of 5.7 seconds and an electronically limited top speed of 250 km/h (155.3 mph).

Is S4 more valuable than A4?
- Power Over the whole powerband, the S4 packs a ton of power. Although the A4 has a lot of “Unlike the S4, which has constant power that is smooth and constantly ready to go, the S4 experiences turbo lag and the power band has several spikes and lulls in it.
- Interior
- Although the A4 and S4 have a similar outward aesthetic, the S4 has a significantly superior interior. There are many additional standard features on the S4 that aren’t as simple to retrofit, such as the color Drivers Information System, even if you can retrofit the S4 Recaro seats like I did on my A4 (DIS).
- Note from the Exhaust
- The S4 has fantastic audio. Nothing compares to the sound of the normally aspirated 4.2 V8 in the S4I’ve heard lots of huge turbo A4s and pretty much every exhaust configuration available for the A4 in my time.
- The Whole Shebang
- Although many A4s with the S-line aesthetic package may resemble S4s, it is not the complete package. The S4 sports improved suspension, wheels, sway bars, differential, and brakes (bigger rotors up front and vented in back). It’s a well-upgraded machine that outperforms the A4 almost in every way right out of the box. If you’re stuck there like I am, “good enough alone this may not matter much (I will probably upgrade/replace all of the aforementioned components in my S4), but this is definitely something to think about, especially if you want to make only minor changes.
- Quattro
- I must admit that having Quattro (AWD), which my A4 lacked, is really, incredibly good. Instead of understeering, skidding, and then waiting until the turn is finished to resume the throttle, the car handles like a dream and not only takes corners with a ton of confidence, but you can actually add power while coming out of the curve. Even after extensive suspension adjustment, my FWD A4 was never able to match the handling of a standard S4 with Quattro.
What distinguishes the Audi A from the Audi S?
The S series, which stands for sports, comes after the A series. The S series Audi cars are significantly faster on the road than the A series Audi cars because they have more standard features and more powerful engines than the A-series Audi cars.
Which is superior, the Audi A4 or A6?
The Audi A6 is bigger than the Audi A4, providing more space for cargo and more back leg and shoulder room. It also has a longer body and a broader wheelbase. The A4 is lighter than the A6, on the other hand, and gets higher gas mileage in base trims.
Which Audi A4 or A5 is superior?
While the A5 has the wider panoramic room as standard equipment, the A4 comes with a motorized sunroof as standard equipment. Although the two sedans’ interior spaces differ slightly from one another, both offer a roomy interior with enough of head- and legroom for both the front and the back passengers.
Audi RS49/10
The Audi RS 4 features a twin-turbo V6 engine under its hood on several occasions. The first RS 4 debuted in 2000 with a 2.7-liter biturbo engine.
This brand-new vehicle shares a lot with the Audi S4 and S5 models thanks to its 2.9-liter twin-turbo engine (they run a 3.0-litre turbo – the engine in the RS 4 is a smaller capacity and has a shorter stroke, but adds a turbo over the lesser S models).
But it’s not a V8. A 4.2-liter naturally aspirated engine with 331kW and 430Nm of torque was used in the most recent model preceding this one.
This new model still produces 331kW of power, but it does it between 5700 and 6700 rpm rather than 8250 rpm like the original V8. Additionally, the torque received a significant boost, increasing to 600Nm.
Not only has torque grown by around 45%, but it is now more evenly distributed across the rev range, spanning 1900 to 5000 rpm, as opposed to the V8’s lower, shorter-lived, and less-usable torque (4000-6000rpm).
And what about the crucial 0-100 km/h time? Whereas it was at 4.7 seconds earlier, it is currently at 4.1 seconds. The top speed stays the same at 250 km/h.
But what about the sound? Read the part below about driving, or even better, watch the video!
What is the best Audi series?
The popular German carmaker manufactures a wide range of vehicles, from entry-level compact luxury cars to full-fledged supercars. They have mastered the art of engine building, and for almost a decade, they have all been winning awards, whether it is for the fastest Audi sports cars or luxury SUVs. Audi is undoubtedly at the pinnacle of its success, so if you’ve been considering buying one, the time is now. The top 10 Audi vehicle models are shown below.
Is S-Line preferable to sports?
If you choose the S Line grade for your new Audi, you’ll get an aggressive bodykit, improved interior design, and lowered suspension for a more thrilling driving experience. Although S Line cars still feature the usual Audi range of engines, they won’t be any faster than the standard car. Instead, they will feel significantly livelier to drive.
Is Black Edition an improvement over S-Line?
You’ve heard the saying “all shirt, no pants,” right? Well, when you possess an Audi S series, you’ll encounter accusations of that nature. Although it appears fast, it is actually no faster than a standard vehicle with the same engine.
The 40 TDI diesel we discussed earlierthe one that achieves fuel economy of more than 50 mpgdoes trade off performance for fuel efficiency. It accelerates to 62 mph in 8.1 seconds, which is three seconds slower than the S6 diesel and twice as long as the 600 PS RS6.
While S line models have reduced suspension, they lack the quattro all-wheel drive found on S and RS models as well as the smart differentials and sizable brakes that make these sportier variants so capable on a winding country road.
Sport is indicated by the S (in the Audi S range). The line simply states that it is a trim level as opposed to the speedier S versions.
The exterior of Black Edition automobiles is matte black rather than chrome, as suggested by the name, which retains the sporty appearance of S line cars.
For greater efficiency, fuel can be squirted straight into the cylinder using TFSI, which stands for turbo fuel stratified injection. By taking the heat out of the intake air, the fuel cools the cylinder, increasing the compression ratio. According to reports, this will increase fuel efficiency by 15%.
