2015 Audi A8 and S8 get some new goodies

Luxury car buyers are a demanding bunch. They've got this crazy notion that just because they're spending the better part of a hundred grand on a top-tier luxury sedan, they should get the very best and the cutting edge of what the industry has to offer. That has tended to come down to the S-Class even when it had grown long in the tooth, and now that Mercedes-Benz has rolled out an all-new version, the competition is falling all over itself to release updates to keep their flagship sedans in the running. Jaguar did that just yesterday with its XJ sedan, and now Audi has revealed the latest revisions to its A8 range.
Set to debut at the Frankfurt show in just a few weeks from now, the latest A8 (and its performance version, the S8) benefits from a series of stylistic, powertrain, and technology upgrades. Among the most prominent, of all things, are the new Matrix LED headlights that can automatically lower the high-beams for oncoming vehicles, with integrated turn signals that light up to point in the direction the driver's about to turn. But that's hardly the end of the story.
Audi has apparently reduced the output on the 3.0-liter supercharged V6 to from 328 horsepower to 310 but raised the 4.0-liter twin-turbo V8 from 414 hp to 435, which now offers a 0-60 run of just 4.5 seconds. That's just three tenths behind the S8, which remains unchanged at 513 hp, as does the 493-hp 6.3-liter W12. The 3.0-liter TDI is up from 247 hp to 258, the 4.2-liter TDI grows from 345 hp to at 385 (with a massive 627 pound-feet of torque to boot) and the hybrid that offers a combined 245 hp and 354 lb-ft. That makes for one massive array of engines globally, although only some of them will be offered Stateside. Each is mated to an eight-speed automatic transmission and Quattro all-wheel drive, but thanks to the A8's lightweight construction, it's lighter than any other all-wheel-drive model in its class.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi confirms autonomous tech for next-gen A8

Like so many of its rivals, Audi is hard at work getting its autonomous driving technology up to speed and ready to reach the market. And now it's revealed when we can expect that time to come – or at least in what form it will arrive. In announcing the achievements of its latest RS7 Piloted Driving prototype, Audi has confirmed that the system will be offered for the first time on the next A8, the upcoming iteration of the German automaker's flagship sedan. Just as we heard this past January, the next-gen A8 will be able to drive itself around town at speeds of up to 37 miles per hour. Ingolstadt still isn't saying when we can expect the new A8 to arrive, but considering that the current model has been around since 2009 (albeit with periodic updates along the way) and that its key rivals – the Mercedes S-Class and BMW 7 Series – are both much newer models, Audi shouldn't be waiting much longer to launch its new flagship. The announcement was made as part of the reveal for "Robby," the latest version of the company's self-driving RS7 concept. The previous version, dubbed "Bobby," was based on the same model, and gave our man Jonathon Buckley over at Translogic a run for his money around Ascari a few months ago. (We'll let you watch the video below to see who fared better). But the new version is a good 882 pounds lighter, lapping the Sonoma Raceway (previously known as Infineon or Sears Point) in 2:01.01. That's in what is ostensibly still a road car, just one that's operated by a computer. The fastest lap ever recorded on the full 2.5-mile circuit, in case you were wondering, was also achieved in an Audi, but that was the R8 Le Mans Prototype that Allan McNish hustled around in a 1:20.68 qualifying lap.

On one of the world's most challenging race tracks, the Sonoma Raceway in California, the latest generation of the Audi RS 7 piloted driving concept has surpassed previous top performances once again. Audi will be offering piloted driving for the first time in the upcoming generation of the Audi A8.
