2015 Audi A8 rises to meet the challenge [w/video]

It's turnover time in the extra large premium sedan segment. With Mercedes having stuffed HAL 9000 in its new S-Class, other luxury marques are quickly updating their own super sleds to keep up with this persistent march of technology. While far from a full redesign, the Audi A8 has changed enough for 2015 in terms of styling, powertrains and new technology to keep it in the conversation.
For starters, the A8's exterior design has been redone, with the most noticeable changes happening up front. The trademark 'gaping maw' grille is a little less gaping, while the headlights now feature a straight lower edge of LEDs, excising the old model's droopy-eyed look. Speaking of headlights, Audi now offers optional Matrix LEDs, the latest in headlight tech, with 25 individual elements per side that can be turned on or off and dimmed as the situation demands. The rear of the A8 has also been resculpted and looks very much inspired by the derrière of the A7, with a single chrome strip connecting the new LED taillights.
The A8's full suite of powertrains has also been upgraded, with the supercharged 3.0-liter V6 now producing 310 horsepower (up 20 according to Audi, though down 23 compared to the US-spec 2013 model). The twin-turbo 4.0-liter V8 is now rated at 435 hp, a solid 20-horse increase that lowers the car's 0-62 time to just 4.5 seconds. That's within spitting distance of the 520-hp S8's time of 4.1 seconds. That aforementioned super sport sedan's engine remains unchanged, as does the 6.3-liter 12-cylinder powerplant in the A8 L W12, but Audi's two diesel engines have both improved, with the 3.0-liter V6 producing an extra eight horsepower (256 total) and the 4.2-liter V8 gaining an extra 34 hp (385 hp) to go along with its more-than-adequate, though unchanged, 626.93 foot-pounds of torque.

Audi Sport launches limited edition R8 but doesn't add any more performance

Audi recently announced that its Quattro division had changed its name to Audi Sport, and that it had a number of new models on the way. One of those models to fall under its umbrella of responsibility is the Audi R8. Today, at the New York Auto Show, the performance arm is showing the limited Audi Sport Edition of the Audi R8. The rorty, mid-engined sports coupe's V10 seemingly already has enough power, as this special treatment appears to be mostly cosmetic. It starts with a set of 20-inch, forged aluminum wheels wrapped in 245/30 front and 305/30 rear tires. The brake calipers get a high-gloss red finish, while the V10 Plus version's brakes have an anthracite finish. The car's signature sideblades and side mirrors get a contrasting red finish regardless of exterior color. The front spoiler, grille, and diffuser insert are titanium black, and the tailpipe trims are finished in gloss black. View 15 Photos Entering the car, occupants are greeted by illuminated door sills. The interior color depends on exterior paint choice, and seats and door trim feature black and red Nappa leather. Seatbacks are embossed with an R8 logo, as is the flat-bottom, three-spoke steering wheel. The wheel features a red stripe at 12 o'clock, as well as satellite engine start and drive select buttons. Dark silver contrast stitching and gloss carbon inlays add more character to the interior. The Audi Sport Edition R8 will be limited to 200 units worldwide, and will start at ˆ181,900 (about $193,100), with the V10 Plus fetching ˆ205,800 (about $218,500). Orders start in May, with deliveries beginning in late summer. Related Video:

AMS Alpha 10 Audi R8 First Drive [w/video]

Horsepower is a relative number. Compared to the 1,500 hp in the last AMS car we drove, the face-melting Alpha 12 GT-R, 900 seems pretty tame. But by any rational standard that's a crazy amount of power, the kind that's hard to grasp in practical terms. When AMS Performance called us and offered a test in the 921-hp Alpha 10 Audi R8, saying yes was easy. Figuring out how to demonstrate that much thrust was the tricky part. Our solution was to head to the drag strip. What better way to show off the wicked alterations wrought by AMS president Martin Musial and his team than a video showing the car do the Star Trek warp speed effect through the quarter mile? AMS has a history of building quick drag strip cars, like the aforementioned GT-R and a series of Mitsubishi Lancer Evolutions. Vice president Arne Toman even owns the world's fastest Hearse. We should have taken the broken scoreboard at Milan Dragway as an omen. Wiped out by a lightning strike, both displays have since been replaced. Before our test both Musial and Toman explained that the Alpha 10 R8 wasn't built with drag racing in mind. But, being good sports, both met us at the track in southeast Michigan, unloaded the R8 from its trailer, and let us run through the timing lights over and over. The best time that day was 11.0 seconds at 136 mph, uncorrected. One of the many amazing things about the Alpha 10 Audi R8 is that it's essentially a bolt-on system. That's fast, but not what you'd expect for 786 horsepower at the wheels. And, honestly, we're not disappointed. First, a 4,200-rpm rev limiter was set too low to launch on the sticky drag strip. Put another way, that drag strip time is almost a street start. For what it's worth, Musial and Toman didn't seem concerned about the numbers. Like we said, they present the Alpha 10 as an all-around performance car, and we believe them. Now, if you go to AMS with the drag strip in mind, Musial and his staff can program whatever launch rpm you desire. (You're on your own for clutch replacements.) A reflash of the engine controller is part of the Alpha 10 package. Drop off a stock R8 V10 at AMS (or any of its 70-plus dealers), and they'll pull out the suitcase-shaped muffler that sits behind the engine. A pair of turbochargers, small mufflers, and two heat exchangers attach to the stock exhaust system mounts, while a giant water-to-air intercooler sits on top of the engine.
