Audi RS5

So, would you have one over the BMW M3?
That's likely what you're asking right now, even if the magnificent 2011 Audi RS5 is yet to be officially confirmed for sale in North America. It's a question we've pondered time and again since Ingolstadt's new performance coupe was first unveiled at the 2010 Geneva Auto Show over a month ago. It's what we were thinking as we travelled to Munich last week to drive it for the first time. And it's the one thing on our mind when we're finally handed the ignition key.

Defining the Enthusiast
Up to this point, we're fairly sure the answer would actually be no. After all, the BMW M3 continues to remain the yardstick by which all performance coupes are invariably measured. As common as it has become after 25 years of uninterrupted production, the M3 is still ahead of the field and, what's more, a hugely rewarding drive. But as we get close to the 2011 Audi RS5 for the first time and catch a glimpse of its muscular rear bodywork, prominent aero diffuser, oversized tailpipes and integrated trunk-mounted spoiler, we begin to doubt the BMW. Then we spot our test car's wheels, a set of the optional graphite-color 20-inchers, and they're carrying 265/35R20 tires in front and 275/30R20 tires in the rear. It is suddenly time to reappraise. We stand and stare, suddenly wondering if the M3 might finally have met its match. On looks alone, the BMW is certainly closely challenged. The Audi RS5 has an instant air of aggressiveness harking back to Audi's most celebrated road car of all time, the original Quattro. You could argue that Audi really didn't need to build this car. The Audi S5 is an excellent car in its own right, after all. But the Audi RS5 exists purely on the premise that more is better. A guilty pleasure, if you like.

The Heartbeat of Ingolstadt
At the heart of the RS5 beats the latest evolution of Audi's naturally aspirated, direct-injection 4.2-liter V8. Spinning it to 8,250 rpm produces 444 horsepower, while 317 pound-feet of torque is available from 4,000-6,000 rpm. This is 95 hp more than the Audi S5's V8 has on hand (although only 8 lb-ft of torque more), and this power plant also surpasses the output of the M3's 4.0-liter V8 by 24 hp and 22 lb-ft of torque. This is essentially the same engine Audi slots into the midengine R8, and the way it delivers its considerable level of thrust makes the RS5 a truly memorable car to drive. At low revs the engine is surprisingly subdued for a car boasting such headline-grabbing acceleration, and it has a pleasingly relaxed character that makes it a sublime companion for long-distance motoring. Regardless of what gear you find yourself in, there's always plenty of urge on tap and a compelling eagerness in the way the engine goes about its business. As the torque figure indicates, however, this engine needs to be worked fairly hard before delivering its best. But that's not a great hardship. The big V8 loves to rev, and it only gets better the more you pour into it, feeling particularly gutsy as you wind it around to the redline. Indeed, the sheer energy released through the final section of the rev range is especially impressive for such a large engine. Another reason to run this V8 hard is the hearty baritone it sings when you've got lots of throttle applied. The camshaft alters, the engine note hardens and the acceleration crystallizes into a terrific crescendo of speed and blaring exhaust.

Shifting for Speed
You'll find Audi's latest seven-speed dual-clutch automated manual transmission as the only gearbox of choice here. In manual mode, the gears change smoothly, precisely and rapidly — enough to persuade you that you'd be no better off with a conventional six-speed manual transmission. In automatic mode the gearchanges are slower, more hesitant and not quite as crisp. But it is nevertheless handy to be able to nudge the shift lever across the gate and go hands-free at times, especially in slow-moving city traffic. The best bit, however, is the integral launch control program. Find a suitable piece of road, dial up Dynamic mode on the Drive Select menu, switch off the electronic stability program, apply the brakes with your left foot and lay down the throttle with your right foot, then release the stoppers. Audi claims acceleration to 100 km/h (62 mph) in 4.6 seconds — a scant 0.1 second slower than the time BMW quotes for the M3 with its own dual-clutch transmission. Top speed is 155 mph, although it can be raised to 174 mph as part of the optional Performance package for this car.

Power to the Road
Like the RS4 before it, the RS5 is fitted with Audi's excellent Drive Select system, which allows you to tailor the characteristics of the car's steering, throttle, gearbox, suspension and even the torque split between the front and rear wheels. The problem, of course, is that in an effort to extract the best from the new Audi you find yourself constantly turning the rotary dial down on the center console to alter each setting rather than concentrating on the road ahead. Deciding on a definitive setting could take you weeks, and that's without taking into account the variations in road conditions. It's easier to accept the preselected modes. If asked to define the main difference between the RS5 and the S5 upon which it is largely based, we would say that it's the sharpness of the new car's responses. Everything its lesser two-door sibling does, the RS5 executes with greater precision. And that also goes for the way it swallows up great distances at high speed. The RS5 is a straight-line weapon with few peers. It's a car that feels immensely fast and right at home on the wide autobahn running south of Munich and beyond, with unflinching stability all the way to its claimed top speed. There's just the right amount of torque to make rapid progress simple. However, there's considerable incentive to run the engine to its limiter, because that's where the power is as well as the exhaust music.

Off the Autobahn
In ultimate terms the 3,803-pound Audi RS5 doesn't possess quite the same clarity of response or overall feedback as a BMW M3, but it has more than enough to make it a genuinely rewarding car to drive hard — and fast. The steering is pleasingly fluid in its actions and extremely accurate, allowing you to place the Audi on the road with great confidence and providing impressive agility at all speeds. With its all-wheel drive apportioning power to all four wheels and a torque-vectoring device between the rear wheels helping to provide neutral handling, the RS5 has so much grip at very high cornering speeds that there's nothing more than a hint of understeer to warn you that the enormous purchase from the tires is about to run out. Fling the RS5 into a tightening-radius bend and you get some lean, but it builds progressively without any unruly pitch to throw you off line and force you to back off prematurely. With such high levels of grip you can afford to be late on the brakes into corners and still have the confidence to get hard on the throttle before the apex to take full advantage of the tremendous traction on the exit. Indeed, the way the RS5 blasts out of corners is one of its finest dynamic traits. And the ride? Fast Audis haven't always been known to combine compliance and control in equal measure. In fact, some performance-oriented models out of Ingolstadt in recent years have been downright harsh. The RS5, however, is different. With the suspension setting in the Drive Select menu switched to automatic, the ride is so good that you wonder how Audi could have gotten it so wrong for so many years.

More Than Just Fast
The 2011 Audi RS5 feels like a class act the moment you pull the door handle and climb inside. Audi has a well-deserved reputation for turning out some of the best production car interiors, and this car upholds that honor with one of the most stylish and high-quality cabins you'll find in any car at any price. If the primary objective of the 2011 Audi RS5 has been to put one over on the BMW M3, then it's hard to see how it has failed. Stylistically, it scores with its aggressive demeanor. See it in the street and you're in no doubt that this is one badass car. It's also hard to argue about the overall effectiveness of its driveline, especially the action of its dual-clutch gearbox. In terms of overall quality, it also scores highly. In the end, it comes down to the driving experience. In ultimate terms, there is very little separating the two cars. You'd buy the Audi for the secure feel it delivers, whether in the dry or the wet. On the other hand, you'd have the BMW purely on entertainment value, as it has a kind of fizz that makes a car so desirable. Clearly it's time for a reappraisal.

Audi has been serious for decades, busily bringing us such engineering breakthroughs as the five-cylinder engine, all-wheel drive, the aluminum chassis, direct fuel injection and competition-prepared diesels. It's been like science class. At least the lab projects have been impressing the neighbors and even winning races at Le Mans.

But with the 2008 Audi S5, the technoid visionaries of Ingolstadt have finally lightened up. After all, we're Americans. We're just a simple people. Speed and style are what sell.

Nuvolari Returns From the Past
Audi has figured out that a coupe should be beautiful, not merely exclusive. Even as the typical German sedan has become a beast with swollen fenders and a massive grille, designed to bludgeon the meek out of the fast lane on the autobahn, the 2008 Audi S5 has a different look. Its curving contours are leaner, more expressive and more energetic.

The face of the new Audi coupe comes from the midengine Audi R8 sports car, and the rest has been inspired by the 2003 Nuvolari showcar. The S5 version of the coupe is set apart visually from the conventional A5 by a radiator grille painted in platinum gray and inlaid with chrome trim, more aggressive bumpers, outside mirrors painted silver and four oval tailpipes.

Overall, this is a car that makes its luxury statement with color and chrome, a look that sets it apart from its German counterparts, the BMW 6 Series and Mercedes-Benz CLK-Class.

A New Way of Going Down the Road
The A5 begins with the structure of the A4 sedan, and it's broadly similar in size, though predictably lower and wider. At the same time, the wheelbase has been stretched 4.1 inches, which comes from relocating the differential for the front wheels ahead of the clutch.

Now the front wheels are carried by a lightweight, aluminum suspension with five links on each side, which is rigidly attached to the body by a separate subframe. Meanwhile the rack-and-pinion steering assembly also has found a new home close to the centerline of the wheels.

When you pencil it out, these changes have a huge impact. There are 5.3 fewer inches of front overhang, so there's less mass leading the front tires down the road, and that means the car is more responsive to steering inputs. The coupe also distributes its 3,807 pounds more evenly, 58 percent front/42 percent rear. And finally the steering is crisper, more direct.

It's in Your Hands
There's a new, down-the-road sense in this car that you can feel as soon as you take the steering wheel. The S5 feels alert, completely different from an A4 sedan or even an RS4.

It's a difference you can measure on the test track. On the skid pad, the S5 balances easily on its 255/35ZR19 Dunlop Sport Maxx tires. It hangs on until you reach 0.91g, which is a fraction more than the Audi RS4 sedan achieves. More important, the S5 maintains its poise even at the limit, and a quick dab at the throttle is enough to change its cornering arc.

The S5 balances nicely through the slalom as well, recording a speed of 68.6 mph, which compares to the RS4 sedan's 70.6 mph. The steering effort of the Audi coupe's speed-sensitive system is a little light, and it's overmatched by the quick turn-in from the chassis and tires, yet the car's overall responsiveness inspires complete confidence. Gone is the vague, on-center steering action that has characterized other Audi models.

This coupe fits the way real Americans drive. It's meant to travel enormous distances at high speed, undeterred by the character of the road or the nature of the weather. As the sporting version of the Audi coupe, the S5 has had its suspension snubbed down to a fairly tight calibration, a measure to keep the inevitable torque reaction of all-wheel drive from disturbing your sense of command and control through the steering wheel.

As you'd expect, these standard 19-inch, 35-series tires are pretty aggressive, though, and they'll patter across the ridges between the concrete slabs on the freeway or across broken pavement.


A V8 That's Perfect for America
Yet it's the engine that dominates the S5, just as it should in a sporting coupe. Audi's 4.2-liter V8 appears once again here, calibrated this time to deliver 354 horsepower at 7,000 rpm and 325 pound-feet of torque at 3,500 rpm.

This long-stroke V8 doesn't have a very sexy reputation, yet it's brilliant in both character and performance. It pulls from very low rpm just like an American-built V8, and then it has another dimension of power that carries you to its 7,000-rpm redline.

The tractability of this engine perfectly suits an automatic transmission, yet we still prefer the crisp throttle response that comes with a six-speed manual transmission. The shift linkage combines fairly long, light-effort throws with firm engagement, so it's easy to use. Even so, the engine has such authoritative power as you roll on the throttle there's not much need for shifting.

If you want to triumph over time from a standing start, you dump the clutch at 4,500 rpm, sense a bit of wheelspin from the front tires followed by a stern kick from the rears, and 60 mph comes up in 4.9 seconds. You pass through the quarter-mile in 13.3 seconds at 104.6 mph. This compares to the 420-hp Audi RS4's 4.7-second acceleration to 60 mph and its quarter-mile pass of 13.2 seconds at 106.8 mph.

Since the Audi V8 will carry this car all the way to an electronically limited top speed of 155 mph, the S5 has brakes that are up to the task, and this car with its standard 17-inch discs comes to a halt from 60 mph in just 110 feet.

Traveling in a Coupe
The Audi S5's interior rejects conventional German austerity for a warm, expressive look, and everything feels wonderful. A panoramic sunroof (it tilts up, but the shape of the roof prevents it from sliding open) also brings more light into the interior.

Audi has also managed the transition to mobile electronics with far more flair and good sense than its competitors. The navigation screen is high in the dash, yet it doesn't look like someone abandoned a microwave oven up there. And the Audi MMI system continues to be the best of these systems, as the central control knob and its surrounding buttons create an interface that quickly becomes intuitive.

At about $2,000, the Audi S5's optional, 505-watt Bang & Olufsen audio system seems like a ridiculous affectation at first, but the interior is such a nice place you'll be thinking up excuses to go out to the garage at night and listen to music.

There's a Message in Style
At the moment, official pricing for the 2008 Audi S5 has not yet been announced, though we understand $53,000 is a reasonable estimate. This would peg it to the price of a Mercedes-Benz CLK550, which the Audi S5 resembles in character far more than the $74,700 BMW 650i.

For decades, Audi has been an artistic success in America, but it's also been largely unencumbered by commercial success. It's reinvented itself over and over again, trying to find the magic fairy dust that will make people notice.

The 2008 Audi S5 will grab people by the neck and make them pay attention. It has the commanding presence of a BMW 6 Series, runs with the Audi RS4 sedan and sits there at the same price as a Mercedes CLK.

Here in America, we're simple enough to understand speed and style. The 2008 Audi S5 is a classic American coupe, ideal for a country where the distances challenge you. You know, purple mountains majesty, amber waves of grain and all that. The science nerds in Ingolstadt must take their vacations here.

Audi A5

There’s nothing quite like a large, premium-brand coupe with which to flaunt your wealth—all that sheetmetal, size, and power, but real seats for only two. It’s no wonder, then, that in such a sybaritic segment, the attention on a new arrival focuses on the most flamboyant member of the family.

Such was the case with the arrival of the Audi A5 and S5 siblings. Although both wear (mostly) the same sensual sheetmetal, only the S5 offers Audi’s melodious 354-hp V-8. We drooled over the shape of the cars, but when the time came to strap on our test gear, we snapped up the S5 and left the base A5 to sit like month-old Peeps on the clearance rack at Kroger.

Silly us. Of course the S5 grabs all the attention and posts the impressive performance numbers (0 to 60 mph in 4.8 seconds by our testing, and the quarter-mile in 13.4 at 105 mph), but the A5, motivated by a 3.2-liter V-6, grabs eyeballs just as effectively and will be the one posting the more impressive sales numbers. And it is certainly no slouch, even before you consider the five-figure discount.

Down 80 or So Horsepower, but Still Smooth, Flexible, and Fast

With Audi’s full battery of power-building and fuel-saving tech at work inside, the V-6 whips up 265 horses and 243 pound-feet of torque and manages an EPA-estimated 16 mpg city and 27 mpg highway, figures better than the V-8’s by 33 and 42 percent, respectively. We observed 15 mpg in our S5 test and 20 mpg with the A5.

Time slips suffer by one second in the 0-to-60 dash and 1.1 seconds and 7 mph in the quarter, with the A5 chalking up a 5.8-second 0-to-60 and a 14.5-second quarter at 98 mph. Although the engine comes noticeably alive at higher rpm, it is admirably flexible and will lope along comfortably at nearly any speed in any gear. At 30 mph, the IP gear indicator calls for an upshift to sixth, dropping the tach to 1000 rpm, where it is still silky smooth even when you floor it. It’s just that nothing happens when you do—sixth-gear acceleration from 30 mph to 50 takes 13.9 seconds, but that’s why God invented the downshift.

Although braking numbers differ by only one foot (158 for the S5, 159 for the A5), the A5 managed to best the S5 on the skidpad, pulling a genuinely sporty 0.90 g. The A5 we tested included the S-line performance package, which, for $2900, brings everything from the more expensive S5 except the V-8’s additional kapow. You get the front and rear fascias, 19-inch wheels, Dunlop SP Sport 255/35ZR-19 performance tires, and a firmer suspension. Although the larger rims and rubber no doubt aided the A5’s superior skidpad performance, they are also more vocal on the highway than the base rubber, thrumming on smooth pavement and emitting a sharp pong over expansion joints, but neither is at an offensive volume.

On winding pavement, the A5’s skidpad advantage disappears in all but the most determined maneuvers—it is nearly two tons no matter how many cylinders are under the hood, and mild understeer is the order of the day—but the car exhibits the same crisp steering action and relatively swift moves of the S5.

Just Settle Down and Enjoy the Ride—and the Envious Stares

Skidpad numbers aside, neither the A5 nor the S5 is an overtly sporting machine. Styling is a very well-executed job one. Ticking no options boxes but the S-line trim will net a visual dead ringer for the S5 with fully respectable performance and a significant fuel-economy bonus at a $7150 discount. If dusting all comers in the stoplight drags or a siren-song exhaust note is priority alpha, then the S5 is the only choice. Or you could go with a BMW 335i, which costs as much as an A5, will pace the S5 in late-night industrial-park shenanigans, but is as common as the sauer in kraut by comparison. But for a comfortable big-coupe knockout that flips a big “screw off” to sensibility and compromise, the A5 will draw envy from every surrounding motorist.
