2010 Audi S4 – Click above for high-res image gallery

We'll just come right out and say it: Audi lost the plot with the last generation S4. Unlike the twin-turbocharged V6-equipped B5, its B6 and B7 brethren did little to stoke the flames in our collective hearts. The "S" simply stood for, "I paid more for a bigger engine and some additional trim." Needless to say, that sort of behavior doesn't cut it when you're battling it out with one of the most competent sports sedan of the last decade: the BMW 335i.

So with the all-new A4 (B8) comes the 2010 Audi S4 – the most credible contender to BMW's hugely competent middle child. This time, Audi brings back the boost. And it's about damn time...

Since there's been some confusion in the past, let's set off by getting our branding barometer calibrated. Audi A4: Entry-level sports sedan. Audi RS4 (due out late next year): High-po competitor to the M3, Mercedes-Benz C63 AMG and Lexus IS-F. Audi S4: Well, that gets a bit sticky...

Audi cites the S4's main competitors as the BMW 335i and 335xi, the Mercedes-Benz C350 and the Lexus IS350. You'll notice one of these things is not like the other.



With the exception of the 335xi, none are equipped with Audi's party piece: all-wheel drive. Naturally, that feature comes at a cost. Starting price of the 335xi: $42,300 with a manual and $43,625 with BMW's Steptronic auto 'box. Starting price of the 2010 S4: $45,900 with a six-speed manual or $47,300 with Audi's new seven-speed S tronic dual-clutch transmission. That's a minor price discrepancy, but a discrepancy nonetheless. So what's the extra coin get you?

BMW's AWD is aimed at snow-bound Northerners; Audi's is a performance upgrade.
If you want to debate whose all-wheel drive system is better, feel free, but we'll save you the trouble: Audi, by a landslide. BMW's AWD option is aimed at snow-bound Northerners; Audi's is a performance upgrade and a brand differentiator. Quattro's been honed to perfection over the last 30 years and, at the end of the day, it's just what Audi does – and they do it properly.

Those interminable days of relentless understeer are nearly a thing of the past, replaced with smooth tracking and seemingly limitless grip. But as we found in review of the 2009 Audi A4 3.2 Quattro, it comes at the expense of engagement. With the S4, Audi sought to rectify the situation by focusing on two things and two things alone: tractable power and enhanced agility.



The first part of the formula comes from the all-new supercharged 3.0-liter TFSI V6, initially offered Stateside in the 2009 Audi A6. Retuned from its upper-midsize sedan sibling, the four-rotor equipped supercharger huffs and puffs 11.6 PSI into the bent six's cylinders, resulting in 333 horsepower at 5,500 RPM and 325 pound-feet of torque from 2,900 to 5,300 RPM. For those keeping track, that's seven horsepower less than the previous 4.2-liter V8, but 23 lb-ft more, all while returning 18 MPG in the city and 27 MPG on the highway (28 MPG with the S tronic). Its gas-guzzling predecessor only managed 13 city/19 highway.

Twist the key and Audi's (overly bitched about, albeit misleading) decision to slap a "T" onto the fenders of its supercharged sedan strikes as a tactical move more than a confusion creator. With the exception of a nearly imperceptible wine from around 2,000 to 3,000 RPM (seriously, had to stick our head out the window), Audi's boosted six does its best impression of a B-movie thriller: it's quiet, too quiet. Thankfully, aural pleasure isn't derived from the lump under the hood. The twin-tipped dual exhaust elicits the slightest burble when mating the throttle to the floor and delivers a pleasing, fuel-drunk "burp" when equipped with the S tronic tranny.



No matter the gearbox, you'll be thoroughly pleased by the shifting experience. The six-speed manual goes together with the supercharged mill like chicken and waffles, while the seven-speed S tronic – the first application on a longitudinally mounted engine from Audi – adds a healthy dose of Vermont's finest maple syrup. Clutch take-up is a bit on the high side, but full acclimation is just a few shifts away, and with the S tronic, Audi continues to prove that commuters and back-road bombers can live together in harmony with a singular gearbox. In full automatic mode, gear selection is intelligent and unobtrusive – even when it reaches for the ultra-tall, fuel-saving seventh ratio – and when twisty time comes, the steering wheel-mounted paddle shifters are more than willing to engage the proper gear based off the only computer we tend to care about: the gray stuff between our ears.

Audi cites a 0-60 time of 4.9 seconds, but focusing on thrust sells the S4 short.
Audi cites a 0-60 MPH time of 4.9 seconds with either the manual or the S tronic, although dialing in your own revs and dropping the clutch with a wanton disregard for mechanical sympathy may deliver slightly quicker times. Regardless of the initial sprint, the new mill's mid-RPM punch picks up where the outgoing V8 left us cold, with a blissfully flat rush of acceleration from 2,000 RPM until around 6,500 RPM, just before the fuel cutoff kicks in a few ticks past the seven-grand redline. Compared to the A6, where its 300 hp seems merely adequate to lug 4,123 pounds of luxury, the 3,874-pound S4 scoots along with quickness, delivering that Germanic missile-guided bank-vault sensation.

But focusing on thrust sells the S4 short. More than any other element, the Sport differential is Audi's pièce de résistance. Coupled with the RS4-inspired rear bias all-wheel drive system (standard 40:60 front-to-rear, with a maximum of 80% sent to the rear), the trick electronic diff – similar to the unit found on BMW's new line of xDrive products – shuffles torque to the outside rear wheel, pushing the car through the bend without relying on ABS-based nannies to heat up the brakes and spoil the fun.



We had the chance to test the S4 with the Sport differential on both an autocross course and through some of the rolling hills around Sonoma's Infineon Raceway, and came away with a two realizations: 1) It's even better than the unit fitted to the positively porky but sickeningly entertaining BMW X6 M, and 2) All the reports of the new S4 "stepping its tail out" on corner exit are daft. Yes, it feels that way, but it simply isn't.

While running around the cones with the Audi Drive Select system set to Comfort, the S4 pushes similarly to the A4. In short: a predictable buzz-kill. However, switch the ADS to Dynamic, disable the stability control and the S4's entire attitude changes. Although we heard some journos still complaining about understeer, we found the proverbial "slow in, fast out" to be the perfect way to attack the bends. Tip into the brakes early, turn in and then start slowly feeding in the throttle. Give it the boot just past the apex and you can feel a measured dose of twist being delivered to the proper wheels. The back end slips slightly and by the time you've straightening the steering, you're riding the red mist towards the next corner. It's thoroughly engaging and completely annihilates one of our primary criticisms of the standard A4.



Out on the track, this time in a Sport diff-less manual model, the core components of the S4 show through. The stiffer springs drop the S4 nearly an inch over optional 19-inch wheels (we've got 18-inchers on our tester with 245/40 rubber), and the additional tire camber and speed-sensitive steering tweaks make the S4 supremely confident around the circuit. Bombing bend after bend, low-speed left-handers and high-speed sweepers are dispatched with a minimum of drama, and although the steering is noticeably more precise than the A4, it still lacks some of the feedback we crave.

What Audi's created is an Evo for the discerning, low-key enthusiast.
Our only real issue stems from the brakes, which have been upgraded from 12.6 to 13.6 inches in front and from 11.3 to 13.0 inches in the rear. After three laps of flogging, pedal feel got progressively mushier and stopping distances increased to sphincter-sucking-seat status. We wouldn't call the S4 a tried-and-true track tool, but with some upgraded pads and stickier rubber, it could easily handle the task.

Back on public roads, the S4 delivers on its mission of being a sports car in a staid sedan's clothing. Few exterior elements distinguish the S from the A, so aside from the tweaked front and rear bumpers, grille, trunk spoiler, aluminum mirrors and standard LED taillights, you're free to fly under the radar of the local constabulary. Even the lowered suspension does little to affect ride quality and interior noise, and on the inside, the gray gauges, black headliner and bolstered seats are a welcome addition to a cabin we've previously praised. The one demerit we would issue is for the window switches, which appear to have been swapped out with lower cost units that feel slightly cheaper than what we've grown accustomed to with Audi. Yeah, we know it's a minor gripe, but we just want ensure it's not a sign of things to come with an otherwise faultless interior (previously voiced MMI issues aside).



Surprisingly, that last point is telling about the overall S4 experience. In the past, if you wanted a forced induction, all-wheel drive monster with telepathic abilities that can make even the most hamfisted feel like driving deities, you were left with a singular option: the Mitsubishi Evolution. However, some of us actually want to enjoy our time inside and stay on the DL while doing it. Cheap plastics, wonky switchgear and a comically oversized (if functional) rear wing are fine when you're 25, but not when you're looking for an entertaining way to end your day while toiling away in Middleagedom. So what Audi's created is an Evo for the discerning, low-key enthusiast. A sports sedan you actually want to drive, but aren't forced to. And on that measure, they've succeeded – brilliantly.

      you can step in a S4 for only 46? thats not half bad
        • 5 Years Ago
        please nobody feed the troll.

        yah but other man, if you max out the options on an M3 it'll cost like, 73, 74k or something... at which point you're at porsche 911 territory. i think the point is for a comparably equipped S4, you'll always be about 10k short of an M3... now i personally think that that's a great deal cuz with the tunability of the S4 mill, 10k can get you a LOT of performance and/or body work...
        • 5 Years Ago
        Fernando, you are way off base. VW and Audi have a very loose relationship, and the new A4/S4 share less than 5% of thier parts; the ones they do amounting to wiring and switches etc. Further, unlike ANY of the japanese brands, they are built in completely different factories.

        You clearly don't have much experience or knowlege in this industry.
        • 5 Years Ago
        I was reading on Edmunds (I think), that the 2010 is $46k whereas last year's model was $57k. So they updated it all and lowered the MSRP more than $10k!!!

        • 5 Years Ago
        audi_arena, Fernando may be a bit off in his comparison of an A4 to a Jetta as far as components go, but unfortunately they do share a less than stellar reputation in reliability. A friend's previous gen S4 was returned as a lemon 6 months into his ownership after 3 faulty manual gearboxes, and various engine and transmission seals that refused to seal, and Audis and VWs are both notorious for electrical problems.
        • 5 Years Ago
        not that there is anything wrong with the jetta...but since when did the jetta and the A4 look anything alike? they are built on completely different platforms, as stated above share nothing but extremely insignificant parts, have no engines in common, and there is no AWD jetta available.
        • 5 Years Ago
        @taipeileviathan

        "yah but other man, if you max out the options on an M3 it'll cost like, 73, 74k or something"

        actually a fairly loaded m3 sedan comes out to around 65k.
        • 5 Years Ago
        In reality, even if they do only share 5% and are built in different locales, a lot of people still think the A4 is as an expensive Jetta. You'd think considering the 95% different parts, they would look more than 5% different.
        • 5 Years Ago
        Yeah I think that's fair too. Problem is a loaded example closes in on 60K, at which point a M3 or C63 are tempting. Then again if you want/need AWD, this is currently the only way to go in a smaller car.

        Go Audi!
      • 5 Years Ago
      The S4 is not a BMW M3 competitor, it's a 335i competitor, so comparisons to the M3 or even the Mercedes C63 are pointless. The RS4 will be Audi's M3/C63 beater.

      0-60 in 4.9 seconds in a handsome saloon/sedan which has a fab interior, and the benefit of AWD sounds good to me.

      In Europe Audi's are considered discreet and exude class, and BMW's are considered flash and a bit of a predictable premium choice of transport... if I had the cash I'd rather go the Audi route.

      Sure, BMW gives better feed back, and flatters the driver's ego with it's tail-out antics, but the Audi is just as quick (if not quicker in real world driving conditions) and covers mile after mile without the unnecessary drama that BMW driver's seem to crave.

      BTW, at high speeds of say 140+ MPH, BMW's become twitchy - Audi's don't. Thanks to Quattro they are far more planted to the tarmac - that matters on the Autobahns.

      It's a shame you guys in North America wont get the S4 Avant, that one hell of a practical, handsome and quick way of getting around.

      M.
        • 5 Years Ago
        So is comparing the S4 to the WRX/EVO and saying those cars are crap. Oh yes that's what Glock was saying, so I guess by his way of thinking me comparing this to C63 and M3 is perfectly fine too.
      • 5 Years Ago
      It sounds great, other than being a little TOO low key for my tastes. It's got the shiny S4 mirrors, but the wheels are a bit bland. Also, that gas mileage improvement is insane with the new engine. Nice job, Audi!
        • 5 Years Ago
        Those are the lame 18". The 19" are better and you can always get the Euro version (RS4 style) and pop them on for the OEM look.
      • 5 Years Ago
      Great review and also great pictures. I really like this car, it sucks that it's unaffordable to me right now.
      • 5 Years Ago
      I have to wonder: if a man-child has a complex or any other inferiority issues, does having nicer materials for the interior of your automobile really help compensate?

      Inquiring Subaru owners wanna know...
      • 5 Years Ago
      So...chicken and waffles eh? I take it that means the 6 spd sucks, because that doesn't sound at ALL apetizing to me. Waffles with strawberries and whipped cream maybe...but with chicken? Ewwwwww...

      As much as I'd like this car, it'll be years before I could afford one. If it's mid 50's loaded in the US I'm afraid to look what it is in Canada, probably 3-4 years average salary here too. Maybe Ford makes a supercharger for the Fusion. Maybe (I know) it aint an Audi, but I thought I read their AWD system splits the power left to right and front to back too...cheap/poor man's Audi. Not exactly going to be hitting any rally circuits anytime soon.

      Do like though...I was hoping to be able to consider the last gen in a couple of years when they come down below 20...but it sounds like the V-8 is a disappointment...?? Too bad...would have liked listening to it. Maybe have to shoot for an old RS4 in another 8 years then. Eh?
        • 5 Years Ago
        wow you canadians... dude don't rip on something till you've tried it. fried chicken and waffles? match made in heaven. they go better together than, well, whatever it is you guys eat up there, like french fries and mayo (which i like, but to most americans they'd find as weird as you find chix+waffle). also chix+waffles is a pretty commonly known combo, i'm surprised you've never heard of it *even* if you've never tried it...
        • 5 Years Ago
        Nor mayo & fries...is that Cdn? Never tried it. I know we have different flavoured chips...bacon Lays for one. Mmmmmmmmmmmmmmm...bacon Lays. Maybe they have 'em now, they didn't several years ago. Who knows what else...Aero, Coffee Crisp...I'm getting hungry. And so off topic for this site! LOL


        Back on...yeah, when you consider what a V-8 S4 cost compared to this one, steal of a deal. Plus the new one is faster. Under-rated maybe? Old one is still faster than what I got, and still more money than I care to pay for a car...for now. I love used cars (Ca-ching$$), and something like this, hopefully, won't have had the bag ripped out of it like a WRX having a more "mature" driver behind the wheel. So I wait a few years...and hope.
        • 5 Years Ago
        Actually, the S4 wont be that expensive in Canada. My dad works for Audi Canada, and i was fortunate enough to try one out over a weekend and i must say, its a great car, way better than the B7 S4 for sure. Anyways, back on topic, they should start at 52 000$ (with 6spd MT). The demo we had was pretty much loaded, minus the 7spd S-Tronic and it came up to 63K. When you consider a base B7 S4 started at 72K, that's a pretty sweet deal if you ask me.

        BTW, I too was surprised by the chicken and waffle duo - I guess it hasn't made its way up here yet.
        • 5 Years Ago
        the b6/7 S4 with the 4.2 is still awesome. don't be afraid to get one of those. put a nice exhaust on that and you will be in heaven. there is nothing wrong with those cars. just get the warranty. as it is with pretty much any german car
      • 5 Years Ago
      Glock23,

      I have driven M3 and C63, and can say they are EONS better than this wannabe RS4. But I don't write long essays to bash the S4....

      There's really only the need for RS4 and the plain-jane A4. S4 is and always has been for ppl who can't quite swing for the RS4.
      • 5 Years Ago
      Great review, although having an Audi A4 with a cvt being the largest paperweight (it's been sitting in my driveway for 2years now) I'll never buy another Audi in my life ...looks good though...just don't like the red on the car...
        • 5 Years Ago
        Oh my, I'm so sorry to hear that. I'm not familiar with legislation in the US about lemons but were there not any lemon laws you could have used to receive compensation for the vehicle? That's an incredibly unfortunate event and what did Audi do regarding the warranty for the vehicle?
        • 5 Years Ago
        Audi_arena.... What exsactly is a real Audi? That's a pretty retarded statement
        • 5 Years Ago
        Maybe if you had done your homework and weren't such a cheap-ass, you would have bought a REAL audi...
        • 5 Years Ago
        The coil pack issue was because of Bosch, and still statistically didn't effect a very high percentage of cars compared with other problems that other brands have had. I know your personal experience is the only one that you know, but as a whole, over hundreds of thousands of cars, it's really not that big a deal.

        Besides, thats what warranties are for.
        • 5 Years Ago
        I'm sure if i bought the worst possible combo from a car company i'd feel the same, like the IS250 awd for example. Audi should have never put the CVT in north american cars, it's bad enough on an altima
        • 5 Years Ago
        Fernando and Jorge: Yes, I am saying there are lesser Audi's. Like all brands, they have a cheap CVT car (always equipped as sparsely as possible) for posers who want to look good, but have no appreciation for the superb engineering of things like Quattro, or thier fabulous multi-link suspension.

        You get what you pay for. If it were up to me, I would drop all the CVT's.
        • 5 Years Ago
        I'm curious to know what happened to your A4 CVT. I remember reading many reviews about the reliability/longevity of such a transmission in a vehicle and the significant performance limitations of a step-less transmission but your case is the first I've heard of failing. Care to share any insight on the condition of your vehicle?
        • 5 Years Ago
        Hahaha Rev jut bought a 96 blazer just for the next round of C4C!!
        • 5 Years Ago
        So audi_arena you are saying that his Audi is not as good as other Audi's? That's funny usually when you stand by a car company there's no. Oh don't get that one because its a POC, but in what I've seen in Audi's they are all crap. One friend A4 2003 50k miles timing belt broke wrecked the whole head. Another friend A4 2005 axle snapped on the highway and wrecked the AWD system. Audi makes great "looking" cars IMO and that's it, buy one just to have it sit in your driveway to look at it, just don't drive it. Just look on MSN auto's for owner reliability ratings they are junk nothing but problems. If you are going to buy one, you better get that 100K mile bumper to bumper, and you better read that bad boy up and down and backwards to make sure you are not getting shafted.
        • 5 Years Ago
        Gotta love that Audi refinement, eh?

        Just lease your Audi like my friend does. When it breaks down in under 3 years, just replace it.

        Or wait for the next round of "Cash For Clunkers"...
      • 5 Years Ago
      Overall I like this car, but I really hate the silver mirrors.
        • 5 Years Ago
        I'm 100% sure that someone will be delighted to swap thier regular painted A4 mirrors for your S4 ones.
        • 5 Years Ago
        Different strokes for different strokes. I love the brushed aluminum mirrors.
      • 5 Years Ago
      Here in Norway this car starts at 1 200 000 kroner (206 900 USD), around 3 times an average persons yearly income.
        • 5 Years Ago
        not just sportcars, a good friend of mine is from denmark, utterly insane what they pay there for any car.
      • 5 Years Ago
      Nice Rear....
      • 5 Years Ago
      The comments about the switches have to do with them feeling expensive, and nothing to do with reliability. These too will probably break if you spill coffee on them.
        • 5 Years Ago
        The reason why Audi have gone back to the "cheaper" switches is because the B6 gen A4/S4 switches peeled badly as did other pieces of trim.
        Some Audi dealers replaced them under warranty, others refused to replace them blaming it in suncream etc...
        So with that in mind Audi went back to using non-coated switches...
