Power – the S4 has gobs of intensity over the powerband. While the A4 has a lot of "get up and go" at full throttle, there is turbo slack and the power band has loads of spikes and respites in it; not so with the S4, which has steady power that is smooth and constantly prepared to go.
Interior – in detail the A4 and S4 are cosmetically similar to one another on the fa , the confidential of the S4 is much nicer. Extensively you ass retrofit the S4 Recaro seats display I did on my A4, beside are overflow of change off importantoptions on the S4 that aren’t so easy to retrofit like the color Drivers Information System (DIS).
The Exhaust – the S4 sounds astonishing. I've heard a lot of enormous turbo A4s in my day, and practically every fumes blend accessible for the A4, and nothing can beat the sound of the normally suctioned 4.2 V8 that is in the S4.
The Full Package – while the S-line appearance bundle on numerous A4s may make those autos resemble a S4 – it's not the full bundle. The S4 has updated brakes (bigger rotors in front and vented in the back), influence bars, differential, suspension, wheels, and so forth. Ideal out of the case, it's a very much redesigned machine that has upgrades over the A4 in almost every zone. In case you're similar to me and you can't leave "adequate" alone this may not make any difference a ton (I will most likely redesign/supplant the majority of the previously mentioned segments of my S4), however this is certainly a remark particularly on the off chance that you intend to keep changes negligible.
Quattro – my A4 didn't have Quattro (AWD), and I do need to state, having Quattro is ridiculously pleasant. The auto handles like a fantasy and not just takes corners with a huge amount of certainty yet you can really include control while leaving the turn, instead of understeering, slipping, and afterward holding up until the point that the turn is finished to come back to the throttle. My FWD A4, even with a huge amount of suspension work, would never stock up to the treatment of even a stock S4 with Quattro.
So the S4 is beautyful, quick, and smooth. What's not to love?
Gas mileage – my S4, regardless of how hard or delicate I drive it, gets a normal of around 18 mpg through the span of a tank (for a sum of around 225-250 miles for each tank). My A4 was upper 20s/low 30 MPGs reasonably reliably. So plan to refuel significantly more regularly…
Maintenance – the S4 is somewhat more high support; in spite of the fact that I haven't had any real repairs yet, my greatest stress is that if the motor were to ever blow, finding a substitution is almost unthinkable. Finding an utilized 2.0T for an A4 is super simple, however the aluminum 4.2 V8 can cost somewhere in the range of $5-20k for the motor alone…
Protection – this wasn't as terrible as I thought, however my premium went up from about $90 every month to $125 every month. Not a major issue, but rather this is a concealed cost to know about.
Adjustment cost and viability – tuning this auto is both more costly and more troublesome. While some essential mods like piggie funnels and a tune will awaken the 4.2 V8, including influence past that requires a great deal of cash for moderately little picks up. The A4, then again, is extremely mod-accommodating and you can include an OK measure of intensity genuinely shoddy. This isn't to imply that you can' t mod the 4.2 V8 S4, and organizations like JHM have done some stunning things with jolt ons alone, however those tuning choices are simply more costly than A4 parts, particularly when you factor in accessibility of utilized parts or deal things.
Would it do everything over once more? Without a doubt. The decision between an A4 and S4, toward the day's end, descends to your needs. As an auto crack, stalwart Audi fan, and somebody that could bear the cost of the switch fiscally, it was a genuinely simple choice for me. Then again, you (or I) could be flawlessly upbeat in an A4, and even play out a great deal of adjustments on it and have an auto that performs and looks stunning. There are positively days when I do miss my A4 (particularly those days including the corner store, haha). When making your assurance, here is the thing that I'd exhort you say something from an individual point of view to enable you to choose if the professionals exceed the cons of S4 possession:
Financial– factor in an additional $8-10k in price tag for the S4, and recall that changes, protection, and support are on the whole going to be more costly as well. In the event that you thoroughly consider a S4 is of your value extend in view of price tag alone, I wouldn't exhort "coming to" for it, as there are huge amounts of extra expenses not far off that may settle on an A4 a superior decision. It's smarter to have additional squirm room with regards to spending plan as opposed to extending your dollar too thin and trusting nothing turns out badly (Murphy's Law adores to strike at those circumstances!).
Gas Mileage – in the event that you intend to utilize the auto as a day by day driver, and have a long drive (paying little respect to whether it's city or turnpike driving), the A4 might be a superior decision. The S4 experiences a considerable measure of gas, and does not give it a second thought in the event that you go delicate on it or not. The gas tank is additionally entirely little (around 17 gallons, plus or minus) so you can experience a tank on even a medium separation excursion pretty effectively. Be set up for this…
What you as of now drive? – on the off chance that you as of now have a B7 A4, and need to move to a S4, you have to consider what you truly need to increase out of the move. On the off chance that you effectively claim an A4, I'd prescribe moving to a S4 for reasons other than needing included power alone (you can simply enormous turbo your A4 if so). For me, I had a FWD Automatic A4 and frantically needed a manual transmission and Quattro, and for this situation that bodes well as that is an altogether unique auto. Another situation where it would bode well is going from a high mileage A4 to a low mileage S4, or going from a B6 to a B7 for the corrective updates, or perhaps from a Sedan to an Avant or Cabriolet. In case you're hoping to move from a 6MT A4 with Quattro and low miles to a 6MT S4 with Quattro with high miles, this may not be a smart thought. In case you will dive in, ensure you are really overhauling and not purchasing an auto that will require costly support soon.
