Verdict

Should you buy one? Well, both the S4 and S5 can depreciate in value quite enthusiastically, in fact you’re potentially looking at a rate of nearly $10,000 a year, the warranty is quite short compared to less prestigious brands and if anything were to go wrong once the S4/S5 is...

The current B9 generation of Audi’s S4 and S5 fleet hit local shores in early 2017, bringing with it a new turbocharged spin to nameplates that previously enjoyed supercharged six and, prior, naturally aspirated V8 power.

Ingolstadt’s middleweight ‘S’ formula was, is and will continue to be considered Audi’s ‘soft rock’ performance in the company of ‘hard-core’ RennSport-chiseled siblings. Closer to the truth is that they occupy a friendly, livable and satisfying sweet spot between the relatively vanilla ‘A’ gear and the high-performance RS excess.

B9 has been a fine S4 and S5 vintage and still is in its recently facelifted guise. The singular recipe blends a 3.0-litre single-turbocharged V6, doling out a potent 260kW and 500Nm, and a befitting eight-speed conventional automatic as a refinement lift over its dual-clutch forebear, of course, via proprietary quattro drive. And it’s a breed underpinned with arguably the finest and most capable chassis of its premium competitive segment.

It could eventually be had in one of five different body styles: the S4 Sedan and Avant wagon, and S5 as a two-door Coupe, five-door Sportback or drop top Cabriolet.

When this generation arrived, pricing kicked off at just under six figures for a clean-skin S4 Sedan and walked up to around $120k for the convertible, many loaded with pricey options, from appearance packages to sports differentials. The mid-sized, middleweight S breed tends to typically lure a more mature professional buyer demographic so a good many used examples will likely to have been pampered and

The mid-sized, middleweight S breed tends to typically lure a more mature professional buyer demographic so a good many used examples will likely to have been pampered and well maintained.

The big lure in 2021 is that earlier examples have copped heavy depreciation – as much as 40 per cent – for what remains a thoroughly contemporary package with current tech and what’s still thrilling sportiness. Virtual Cockpit digital instrumentation, Apple CarPlay/Android Auto mirroring, all thoroughly new school and minted with Audi’s deft eye and craft for appealing luxury interior appointment.

While the S4 versions, specifically, were treated to expansive sheet metal revisions for the MY21 facelift currently in showrooms, plus a tickle to the equipment list, including larger touchscreen infotainment range(s) wide. But mechanically little has changed since 2017.

It’s of no surprise that the sedan has been the big S4 seller though Audi’s fast (and faster) wagons have enjoyed fair popularity with something of a cult following. In S5, the impressively practical liftback Sportback has enjoyed the most buyer attention, outselling the two-door Coupe five or six to one.

Worth considering, too, is that many used examples will have aged beyond the surety of Audi’s slim three-year warranty period, one key reason why existing buyers will be moving them on.

  • The 3.0-litre turbocharged V6 and torque converter automatic combination in the S4 and S5 are proving to be very solid.
  • This engine and driveline combination is shared across a large range of Volkswagen Group products from The Audi Q8 through to the Porsche Panamera and Cayenne so while you can expect the typical luxury car bugs, don’t be concerned with being left on the side of the road either.
  • The V6 in B9 series went through a change with the B8.5’s supercharger being replaced by a turbocharger and the torque increased by a good margin.
  • We’ve found that the 3.0 V6 still seems to be one of the most reliable German engines available even after the switch to a turbo.
  • However, water pumps and thermostats can still cause some issues, there are reports of PCV valve failure, carbon build-up is possible and thanks to the immense performance, both the S4 and S5 can have quite the appetite for brakes.
  • Externally, it’s critical to use genuine Audi or Audi approved windscreens as cheaper glass can cause havoc with the plethora of sensors.
  • Early model S5 Sportback window mechanisms can be overly sensitive when raising, resulting in the window failing to raise at all.
  • Parking sensors can be faulty on early models however, this should have been resolved under warranty.
  • Internally, the infotainment systems and Audi Virtual cockpit can glitch and falter however this is not a common issue as such and again, should have been resolved under warranty.
  • Overall, the B9 series of S cars are proving to be reliable and dependable, so far.

Should you buy one? Well, both the S4 and S5 can depreciate in value quite enthusiastically, in fact you’re potentially looking at a rate of nearly $10,000 a year, the warranty is quite short compared to less prestigious brands and if anything were to go wrong once the S4/S5 is out of warranty, being a premium branded European car that is heavily equiped with complex technology, the cost of parts and labour can potentially escalate quickly.

So, if we were to be logical, no you shouldn’t buy an S4 or S5, but surely logic is subjective isn’t it?

In that case, how about we look at it this way. For what an S4 or S5 asks for on the used car market, they offer an immense amount of car for the money. With even a mild tune both will very nearly match their RS counterparts in terms of performance for potentially $50,000 less and while the S4 and S5 exude comfort, class and sophistication, they can also be down right juvenile and savage if or when you want to let your hair down.

If you’re in the financial position to easily absorb the depreciation and have some money set aside just incase something were to go wrong down the track, yes you should buy an S5, or an S4.

Even if you’re in the market for an RS4 or RS5, we highly recommend trying an S4 or S5 first as the performance difference can be easily remedied and you’ll potentially
