2012 Audi S8

2012 Audi S8

What it is: The sportiest version of the Audi A8. While the previous S8 had a Lamborghini-based 5.2-liter V-10, the new S8 has a twin-turbo V-8.

Why it matters: Audi’s last S8 didn’t exactly wow us, and this one has a bunch of new competitors. But, based on our experience with the new A8, things look promising for the top Audi sedan.

Platform: The latest A8’s aluminum space frame and body.

Powertrain: A 520-hp, 4.0-liter turbocharged V-8.

Competition: Aston Martin Rapide, Maserati Quattroporte, Mercedes-Benz S63 AMG, Porsche Panamera.

What might go wrong: Very little. This will be the most fun-to-drive A8 by far, and big sales volumes are not what Audi is going for.

Estimated arrival and price: We expect it to hit dealerships in 2012, at a cost of more than $100,000.

2012 Audi S8

2012 Audi S8

Audi claims it builds the sportiest cars in the premium segment, but another carmaker headquartered just 50 miles south, BMW, begs to differ. The battle is raging—and we couldn’t be happier. Early next year, Audi will launch its sportiest A8, the S8, as its latest volley. From what we know so far, it has the potential to become our favorite luxury car.

Powered by a twin-turbocharged, 4.0-liter V-8, the upcoming S8 will make 450 hp, matching the current model's naturally aspirated V-10. But it will produce significantly more low-end torque, which is one of our few issues with the current S8. The V-10 never felt as strong as its power suggested, although we will miss the sweet sound, which suggests that of a distant Formula 1 racer. What we won't miss is the V-10's appetite for fuel; the turbocharged V-8 will bring considerable improvement in that regard.

The upcoming 4.0-liter V-8 is a new, direct-injection engine which will also be built in a single-turbo configuration with a 400-hp rating. The lower-output unit will be offered in the regular A8, where it will replace the current naturally aspirated, 4.2-liter V-8. And it will power the S7, the sporty top-of-the-line version of the hatchback A7.

The Audi S8 will be differentiated from the regular A8 by exclusive S wheels, a four-outlet exhaust system, and an integrated rear spoiler. The interior will reflect its sporting aspirations with special seats and trim.

"Audi is pursuing the same path which BMW is following with its M models, where the lack of synergies with Formula 1 has led to the abandonment of V-10 engines," says Andrew Fulbrook, analyst at CSM Worldwide in London. He predicts that "Audi's V-10 engines will be limited to the R8 and to Lamborghini."

The S8 will be the sportiest A8, but not the most powerful: This honor will belong to the A8 W12, which will be launched this fall with a naturally aspirated, 6.3-liter W-12 that makes 500 hp. That's less than BMW's turbocharged 760Li, but the Audi, with its all-aluminum body, is the lighter car. Keep the battle going, we say.

2012 Audi A6

2012 Audi A6

There was some disappointment in Germany when the 2012 Audi A6 was unveiled. The seventh generation of Audi’s executive sedan looks an awful lot like the previous A6, not to mention the smaller, less expensive A4. It is an all-new car, but it didn’t take the visual leap forward that some previous A6 generations or their predecessor, the 5000, did. The difference is in details such as the pronounced shoulder line, protruding door handles, and finessed shapes of the grille, headlights, and taillights.

The perception that this redesign relies solely on nuance changes as soon as you enter the car. Audi’s interiors have been best in class for years, but the new A6 raises the bar another very significant notch by integrating much of the interior from the A7. The company is proud of the A6’s optional layered-oak trim, but we’re divided on it; check it out in person before ordering. The overall atmosphere and the attention to detail are simply unbeatable in this segment.

The instrument layout is dominated by a large screen between the tach and speedometer. It displays all kinds of information, including a feed from the thermal night-vision system on cars so equipped. A head-up display is optional for people who always want their information immediately available.

Really Good Six

Speaking of engines, the top-of-the-line A6 is still powered by a supercharged 3.0-liter V-6 that produces 300 hp from 5250 rpm to its 6500-rpm redline and 325 lb-ft of torque from 2900 to 4500 rpm. Compared with the supercharged V-6 in the previous-generation A6, this engine is more efficient, owing to an electric power-steering pump and a new oil pump. The compact, Roots-type Eaton TVS supercharger is virtually inaudible, thanks to the work of Eaton’s and Audi’s own engineers.

On the road, this powerplant steps off forcefully and builds torque evenly and rapidly. It emits a pleasant, sonorous sound that is unusually sporty for a luxury sedan yet unobtrusive enough not to scare away the nonenthusiast buyer. In the Euro-spec car we drove, the intermediary between the six and the Quattro all-wheel-drive system is Audi’s DL501 seven-speed dual-clutch transmission. (We'll actually get Audi's eight-speed automatic with this engine.) It shifts quickly and helps deliver better fuel economy than a torque-converter automatic would, but the manual mode could use some work. If you select a gear that the box doesn’t anticipate, the shifts can get a little jerky. Moreover, the system won’t process multiple shifts at once, meaning you have to order them one gear at a time. And it upshifts by itself at redline, so if you hold off too long and pull the paddle right as the engine tops out, you may find yourself shifting up two gears instead of one—which happened to us more than once. You’re probably going to want to ignore the manual mode.

Drives How it Looks: Beautifully

The A6 uses the latest version of Quattro, with a nominal front-to-rear power distribution of 40/60 percent. Add to that an optional sport differential that actually distributes torque instead of cutting it off like stability-control-based “torque vectoring” systems offered on cheaper cars, and the A6 is supremely capable. The electromechanical steering is nicely weighted, and its feel is vastly superior to that of the BMW 5-series, which has had most of its feeling snuffed out by a new electric booster.

The A6’s modular longitudinal platform places the front axle farther forward than in the old, nose-heavy A6s, making for far better weight distribution and greatly reducing the car’s tendency to understeer. The dynamic abilities of the new A6 also are enhanced by its lower weight. Audi managed to shave almost 300 pounds off the old car’s heft with extensive use of lightweight materials, mostly aluminum.


The A6 will stay on top of things even when the driver isn’t—perhaps because he’s lost in the sounds emanating from the top-notch, 1300-watt Bang & Olufsen stereo. The adaptive cruise control works from 0 to 155 mph, and it can bring the car to a full stop when necessary. A side assistant monitors the blind spots, lane assist acts on the steering system to keep you in your lane, a crash-sensing system will apply brake pressure even if you stay oblivious to looming disaster, and the night-vision system will highlight pedestrians in your path. Still, we’d prefer you just pay attention.

Passengers Limited to Two Computers Apiece

Your passengers will appreciate the fact that the A6 is a wireless internet hot spot that can support up to eight computers—which seems utterly unnecessary. The nav system includes a Google Earth bird’s-eye view. You can operate it with the MMI controller, by voice, or with Audi’s touch pad that recognizes letters—even poorly written ones. Among our favorite features are the full-LED headlights. The light they emit is colder and brighter than xenon, and they are styled to add a cool menace to this executive sedan.

For the U.S., the A6 will be offered initially with only the V-6 and Quattro, but a front-drive model with the 211-hp, 2.0-liter turbocharged four-cylinder and Multitronic CVT will follow. Other markets will get a hybrid based on the four, but we’ve been told that model will not come to the States. Audi is likely to add the powerful and torquey 3.0 TDI to the portfolio later, and by the middle of 2012, we’ll see the S6, powered by the same turbocharged 4.0-liter V-8 that you’ll find under the hood of the entry-level Bentley Continental. That model is probably worth waiting for, but for the impatient or those with smaller budgets, the A6 3.0T is already pretty close to perfection.

Lexus LF-Gh Hybrid Concept

Lexus LF-Gh Hybrid Concept

The Lexus GS sedan can be considered the Jan Brady of luxury sedans. Capable, but generally unremarkable and hardly a segment-smasher. Evidently, Lexus’s middle child is ready to shake things up, and will strut its stuff as the LF-Gh hybrid concept on the show stand at the 2011 New York auto show.

Lexus claims to have started with a clean sheet of paper, but from the side it looks a lot like a scaled-up version of the IS sedan, while the body-side contouring appears virtually identical to that of the big LS. The LF-Gh measures 192.5 inches long by 73.6 inches wide, making it about 2.5 inches longer and almost two inches wider than today’s GS450h. However derivative of its production siblings the car may be, it should be noted that the LF-Gh’s more-conventional sedan shape represents a shift from the fast profile of GS generation three. But don’t rule out the introduction of a sexy five-door fastback to the GS lineup, to counter the likes of the Audi A7; it’s possible that the Japanese company could jump on that German-led bandwagon.

Among the immediately noticeable stylistic elements are LED headlamps rendered in funky bubbled glass; an attractive rear end with razor-sharp taillamps that wrap around the side; and of course, the massive, pinched “spindle-shaped” grille, which shows there’s a pulse at the Lexus design studio—it’s bound to stir up some controversy. Also worth noting are the separate L-shaped banks of LED running lamps up front and the sharp sheetmetal-to-bumper cutline at the rear. Lexus says that the LF-Gh concept “explores a minimization of traditional features such as side mirrors and door handles,” the result of which looks pretty cool here but definitely won’t make production.

The company was short on details regarding the interior other than to mention it will be driver-oriented—a sharp departure from the current GS—and will feature a clock with a three-dimensional face. (So, uh, a regular clock?) Lexus also declined to say much about what’s under the skin of the concept, other than to mention the 20-inch wheels are turned by one of its hybrid powertrains; presumably, this means a V-6/electric combo that will beat the current GS450h’s 292 hp, 267 lb-ft of torque, and EPA city/highway ratings of 22/25 mpg. Production models will certainly also have six- and possibly eight-cylinder gas-only options.

Oh, and get used to that grille—it previews the faces of Lexuses to come.

2014 Audi S4 and S5 Massively Lighter, To Use Turbo Fours

2014 Audi S4 and S5 Massively Lighter, To Use Turbo Fours

The current Audi S5 coupe is gorgeous, fast, and luxurious, but at over 3800 pounds, it’s not dainty. And the upcoming 2010 S5 cabriolet will weigh about 4300 pounds—more than a lot of mid-size SUVs—so forgive us for thinking Audi product planners were being intentionally ironic when they spoke at the car’s launch about their green philosophy and success in downsizing. They conveniently neglected to mention weight and focused on their powertrain strategy: a far more efficient supercharged 3.0-liter V-6 replaces the naturally aspirated 4.2-liter V-8 in the S5 cabriolet and S4 sedan for 2010, with the S5 coupe getting the new engine for 2011. These cars are claimed to achieve the same acceleration as the V-8 models while using 20 percent less fuel.

Still, any idiot knows you can only get so far with engine downsizing in a performance car that weighs more than two tons. So we sat down with Michael Dick, Audi's global head of product engineering, and asked him about how he squares the company’s stated smaller-is-better credo with the reality of its hefty cars.

Crash Dieting

We expected to hear some mumbo-jumbo about how safety standards and consumer expectations for features and refinement dictate ever-growing curb weights, but Dick's response shocked us: Audi is currently testing a prototype of the next-generation S5 that weighs 880 pounds less than the current car. He outlined the ongoing increase in the use of aluminum, magnesium, and high-strength steel as a main reason behind the mass reduction. The current TT's chassis is 69 percent aluminum, and the next-generation A6 (probably due in 2011 or 2012) will have an even higher proportion, Dick says. The amount for the next A4/A5/S4/S5 will be higher still when they debut, likely as 2014 models.

Dick also said that the supercharged 3.0-liter V-6 is an "intermediate step" for Audi. The next S4 and S5 will have lighter turbocharged four-cylinder engines. We can look at the TT lineup for direction: the base TT in the U.S. has a 2.0-liter turbo four that makes 200 hp. The TT S has the same basic engine, but makes 265 hp with beefed up internals and a bigger turbo. Future S4 and S5 models will have about 20 percent less weight and up to 30 percent less engine displacement than the current S5, making combined fuel economy in the mid to high 20-mpg range likely.

Good Looks, Lofty Goals

Although Dick told us the existing S5 prototype uses the current car's styling, we were able to get insight into the next car’s design from another company source, namely the Sportback concept shown this year at the Detroit auto show. This "concept" isn't a concept at all—it's the Audi A7 that will debut later this year in production form. Company insiders tell us that while the car's overall proportions won't be used on other models, its sinister headlights, more-defined single-frame grille, and blade-like taillights will be defining graphic elements on the next generation of Audis.

So it will look good, and Dick claims that even with all the safety and luxury features of today's car, it will weigh only 3000 pounds. He goes so far as to claim it laps Germany's famed Nürburgring Nordschleife eight seconds faster than the current S5. Skeptical? So are we. Industry sources tell us Audi hasn't yet taken enough weight out of the car's structure to achieve the stated goals, and we get the impression that Dick is telling us about the project to force his development team to make good on the claims. If you assume a car's engineering must be completed three years before it goes into production, they only have a couple of years to achieve these aggressive targets. We wish them the best of luck.

2011 Audi A5 Sportback Not for U.S

2011 Audi A5 Sportback Not for U.S

A few months back, our spy shooters nabbed a few pics of the saucy A5 Sportback. Admittedly, we got a little giddy at the thought of the sexy slant-back scouting our streets. Alas, Audi has officially stated that it has no current plans to sell the new model in the U.S.

Along with an official teaser image, the German automaker released a short statement discussing its record worldwide sales and profitability and record levels of U.S. market share, and reiterated its goal to become the leading premium brand by 2015. It sees the U.S. market as “vital” to the success of the company, but is content with its current and planned future offerings. The larger A7 Sportback concept, which debuted at the 2009 Detroit auto show, is expected to be a strong candidate to arrive in the U.S. market, where it would compete against the Mercedes-Benz CLS.

Globally, Audi still intends to grow its current range to 42 models. It says some of those new products will come to the U.S., but it feels it must keep a proper balance here between its core products, such as the A4 and Q5, and model derivatives like the A5 Sportback. We are disappointed but not surprised at this announcement; recent years have seen us denied the latest fire-breathing, 580-hp RS 6 sedan and Avant, as well as many other powertrain combos that are offered elsewhere around the world. In any event, here’s to hoping the grass doesn’t always stay greener on the other side.

2012 Audi A7 3.0T Quattro

2012 Audi A7 3.0T Quattro

As a stylistic distinction, the term “four-door coupe” has edged perilously close to cliché territory, and we’re grateful that Audi has managed to avoid reveling in it in connection with the new A7, although the company does still use the terminology.

Still, the descriptor—it first appeared in the automotive lexicon nearly eight years ago, when the Mercedes CLS-class concept dazzled sedandom—is more relevant here than in many applications that have come along since, with far less justification. (The Acura ZDX comes to mind.) After all, the A7 has the same styling that distinguished the original CLS—a flowing roofline that swoops down at the rear, disguising the presence of that second set of doors.

In fact, it can be argued that Audi’s take on the FDC genre is the best yet. The design preserves sedan proportions, but as a hatchback/wagon, it doesn’t have to make any compromises to accommodate a formal trunk. At any rate, regardless of whether you go along with this car’s solution, we think this description is beyond dispute: wunderbar.

A6 in Disguise

The foundations for this dramatic sedan are new but will soon see service in support of the next generation of Audi’s A6 sedan, due to go on sale here this fall. But compared with the forthcoming A6, the A7 is longer, lower, and wider—a design mantra that originated in the 1950s and still works today. Overall length is up 2.1 inches to 195.6, the roof—55.9 inches at its apogee—is 1.4 inches lower, and width is up by 1.4 inches—all contributing to the dramatic appearance.

Consistent with other Audis and, indeed, with nearly all German chassis, the A7 architecture seems as stiff as the royal wedding, a fundamental prerequisite of handling certainty. Audi literature makes much of the A7’s aluminum content, which includes 20 percent of the bodywork, and the company claims that its glamorous hatchback weighs some 15 percent less than comparable steel-bodied cars. Maybe so, but “lightweight” is not a term that comes to mind in connection with the A7. Our test car tipped the scales at a hefty 4260 pounds.

Mass vs. Muscle

Mass is always the enemy in vehicle dynamics, but the A7 seems to handle its two tons with better-than-average aplomb. Power, supplied by Audi’s supercharged and intercooled aluminum V-6—3.0 liters, DOHC, direct injection, 310 hp, 325 lb-ft of torque—and delivered to all four wheels via a seamless eight-speed Tiptronic automatic, deals surprisingly well with that A7 heft.

This is basically the same setup offered as the standard powertrain in the Q7 SUV. Compared with that one, the A7’s curb weight makes it a veritable wraith, and the supercharged six propels the new hatchback to 60 mph in 5.4 seconds, to 100 mph in 13.5, and through the quarter-mile in 13.9 at 101 mph.

Acceleration is a little deliberate right out of the blocks—it’s hard to think of the A7 as quick—but comes on strong as momentum gathers. As an index, we recorded passing times—30 to 50 mph and 50 to 70—of 2.8 and 3.6 seconds, respectively. These are very good numbers and an aspect of performance that’s much appreciated when you’re exploiting a marginal passing window on a two-lane highway.

Fuel economy is another area where the A7 does well in spite of its curb weight. The EPA forecasts 18 mpg city/28 highway. We averaged 23 mpg in 873 miles of driving, much of it spirited.

Pretty, Yes, but Does She Dance?

Overassisted at low speeds, the steering comes to life above about 40 mph, delivering a more comprehensive menu of tactile information, as well as more weight. It’s gratifyingly quick at 2.7 turns lock-to-lock, and if the A7’s responses to inputs are a little deliberate, they’re decisive once they happen, and free of quirks.

The car’s mass is most apparent in a series of quick directional changes—autocross-level transient response isn’t its strong suit. And as we expected, the combination of curb weight, all-wheel drive, and a forward weight bias adds up to progressive understeer. However, we should mention that Audi has been working hard to correct its chronic nose-heaviness. The A7’s fore-to-aft weight distribution is 54/46 percent, which is approaching the split in some rear-drive cars.

We also were impressed with the A7’s grip, which came in at 0.91 g, delivered by a set of 265/35 Yokohama Advan Sport tires on 20-inch aluminum wheels. That’s not a lot of contact patch for a fast two-ton sedan, but the tires inspired confidence, and the car was at its best on sweeping turns at some eye-widening speeds.

There’s more. Braking performance was consistent and strong—157 feet from 70 mph. And ride quality was simply outstanding, particularly in view of those low-profile Yokes. Even on stretches of rural Michigan pavement resembling asphalt quilts, the A7 was composed and comfortable, damping the hard edges of the nastiest lumps and ironing out the rest.

The Inner Car

In our first-drive report, we noted that the A7 “oozes opulence and simplicity.” The word “stunning” also appeared, and these descriptors seem all the more accurate now that we’ve had more seat time.

The preview catalogued the A7’s garden of electronic systems—the touchpad that can recognize fingertip longhand script (except, perhaps, from doctors); blind-spot monitoring; lane-keeping assist; and adaptive cruise control that’s capable of bringing the car to a complete stop.

We also mentioned the head-up display, and with more experience, we’ve developed some ambivalence about this feature. The speedo repeater is helpful, especially in busy areas where glancing down at the actual gauge can be dicey. But the proximity warning that flashes when the car’s radar decides you’re too close to the car ahead gets to be pretty annoying when you’re dissecting traffic. “Mother, please! I know how to do this! Stow it!”

Speaking of stowing it, there’s a lot of stowage space under that rear hatch—24.5 cubic feet—and, as with all hatches, the cargo well is easier to get at than a conventional trunk’s.

Our test car did indeed ooze opulence. There are superb front seats with lots of adjustability, excellent audio, electronics galore, and rear seats with plenty of leg and headroom, the latter a pleasant surprise given the sloping roofline. We were particularly smitten with the optional, nearly matte oak interior trim. Score another victory for Audi interior design.

The Price of Prestige

Opulence, as you’d expect, doesn’t come cheap. We originally forecast a base price of $55,000. Wrong. Try $60,125.

That includes the Quattro all-wheel-drive system and supercharged V-6—the standard (and only) setup for U.S. versions of the A7—as well as a good array of features: heated leather seats, a power liftgate, a power sunroof, automatic climate control, and xenon headlights, among plenty of other kit.

But there are tempting options packages—Sport (20-inch wheels, firmer suspension); Innovation (LED headlights, adaptive cruise, head-up display, night-vision assist); Prestige (S-line trim, power-adjustable steering column, ventilated front seats, ambient interior lighting); and Bang & Olufsen sound (15 speakers).

Check all those boxes, and you’re looking at $81,530, or exactly the amount on our test car’s Monroney. At that point, you might be tempted to look at some other choices: The A8 starts at $78,925, after all, and the Mercedes CLS550 offers nearly 100 more hp for $72,125. You might also begin wondering what sort of price tag we’ll be seeing when autumn ushers in the new A6.

But A6 or something completely different, it’s clear there are few cars that will be able to upstage the satisfying A7 in sheer curbside wattage.
